Fly Control Begins Before Summer Pressure Peaks

Wed, 13 May 2026 17:48:48 GMT

It usually starts with a few flies around the calf hutches or some extra tail switching in the freestall barn. Then, almost overnight, cows are bunching, calves are irritated and employees are swatting flies left and right.

By the time all of this becomes noticeable, fly populations have often already been building for weeks. Fly control experts say the best chance to stay ahead of pressure is to start managing breeding areas before summer heat and rapid population growth take over.

Small Problems Turn into Big Populations Fast

Flies reproduce quickly once temperatures rise. According to Roger Moon, professor of entomology at the University of Minnesota, flies can complete a generation every 40 to 60 days during spring weather and as fast as every two weeks during the hottest parts of summer.

That means the bedding pile or leftover feed that seems harmless early in the season can become a major source of fly pressure later in summer. Calf areas are especially vulnerable. Wet bedding, spilled milk replacer, manure and leftover feed create ideal conditions for flies to breed.

“Fibrous plant material enriched with manure, urine and moisture are basically the perfect environment for maggots,” Moon says.

Some of the most common breeding spots on dairies include:

Overwintered manure piles
Soiled calf hutch bedding
Bedded-pack barns that were not cleaned out over winter
Feed buildup around bale feeders
Wet feed refusals
The crusted edge around manure lagoons

Moon recommends scouting these areas every one to two weeks during the spring and early summer using something as simple as a garden trowel to look for maggots before populations explode.

Different Flies Create Different Problems

Not every fly on the farm behaves the same way, which is why identifying the type of fly matters before building a management plan.

According to Claire LaCanne, Extension educator in ag production systems, dairies most commonly deal with stable flies, house flies, face flies and horn flies.

“You’ll want to determine what’s pestering your animals to figure out the various methods for managing that particular fly problem,” LaCanne says. “Identifying the type of fly or flies that you are dealing with on the farm along with understanding their lifecycle is key to developing an effective fly management plan.”

Stable flies and house flies are considered “premise flies” because they reproduce in confined areas like barns, calf bedding and manure piles.

Stable flies are the bigger concern from a cattle comfort standpoint because they bite and feed on blood. They are commonly found on the legs and trigger behaviors like bunching, tail switching and foot stomping.

“Stable fly presence can result in reduced production,” LaCanne says.

House flies, meanwhile, do not bite. Instead, they feed on secretions around the eyes and nose and are generally more of a nuisance, although they can contribute to disease spread around the farm.

Flies Cost More Than Annoyance

It is easy to think of flies as just another irritation that comes with summer, but the impact goes much deeper than that.

Heavy fly pressure has been linked to reduced milk production, lower weight gains and weaker immune response. Flies also contribute to the spread of diseases like salmonella, E. coli and pinkeye.

Then there is bunching.

Anyone who has walked into a pen during heavy fly pressure has seen it. Cows crowd together tightly with heads in and tails out, stomping and constantly shifting positions.

Moon says bunching is one of the clearest signs that fly pressure has gotten out of hand.

“You’ll see them milling for position, stomping and switching their tails,” he says. “Bunched stock grow slower, lactate less and have lower immunity because of stress.”

Researchers have also found that bunching creates another set of problems. Airflow between cows decreases, heat builds faster, resting time drops and cows spend less time eating.

What starts as cows trying to get away from flies can quickly lead to lower intake, less resting time and reduced performance across the pen.

Sometimes the Damage Shows up Later

One of the more frustrating parts of fly pressure is that some consequences do not show up until months later.

Stable flies repeatedly biting cattle legs can contribute to hoof problems over time because cows spend more hours standing and shifting weight instead of lying down comfortably.

Moon says animals dealing with prolonged fly irritation may eventually develop sole ulcers or abscesses, issues that often become noticeable in the fall long after peak fly season has passed.

Sanitation Still Matters Most

Even with all the new fly-control products available, most experts still come back to the same basic message: cleanliness matters.

“Cleanliness and sanitation is the most important step in a fly management plan,” LaCanne says.

Removing breeding material interrupts the fly life cycle before adult flies ever emerge.

That means staying ahead of manure buildup, keeping bedding dry and cleaning out problem areas before temperatures really warm up.

“To manage stable flies and house flies, start with sanitation,” LaCanne says. “Doing your best to remove possible breeding sites like rotting hay or grain, spilled feed or TMR, manure piles and other decaying matter is the most effective way to manage stable flies and house flies.”

She recommends scraping, hauling, spreading or composting soiled bedding every other week during the summer if possible.

Several additional management steps can also help reduce pressure:

Move calf hutches and replace bedding after each calf
Use sand, sawdust or wood shavings during summer months
Mow grass and weeds around barns and lagoons
Compost manure properly so temperatures reach at least 140 degrees Fahrenheit
Place fly traps away from barns to draw flies away from cattle areas

Layering Strategies Works Best

Most farms that successfully control flies use multiple approaches together rather than depending on one product. LaCanne says scouting should become part of the routine.

“You should begin looking for signs of flies early in the season,” she says. “Dig or scrape around in areas with organic matter and search for larvae and pupae to figure out where your trouble areas are.”

Sticky traps can also help monitor population pressure and determine when additional controls may be needed.

When fly pressure builds despite sanitation efforts, additional tools can help.

Premise sprays may help suppress stable flies and house flies in enclosed areas, though LaCanne stresses they should be paired with sanitation rather than relied on alone.

Fly baits are most effective against house flies, while pasture fly traps can help reduce horn fly pressure on grazing cattle.

Biological controls are also gaining attention on dairies.

Some farms release parasitoid wasps, often sold as fly predators or fly parasites, to target fly pupae before adults emerge.

“Parasitoid wasps can provide effective management when used with other methods, especially diligent sanitation,” LaCanne says.

However, she cautions that insecticide use can interfere with beneficial insects, making it important to think carefully about where sprays are applied.

Start Before the Flies Force You to

One of the biggest mistakes farms make is waiting until fly pressure becomes obvious before taking action.By the time cows are bunching and calves are restless, fly populations are already well established.

According to Moon and LaCanne, the farms that manage flies best are not necessarily the ones reaching for more sprays in July. They are the ones that dealt with breeding areas early, before populations had a chance to build.

Bovine Tuberculosis Detected in Michigan Dairy

Tue, 24 Feb 2026 19:18:18 GMT

The Michigan Department of Agriculture and Rural Development (MDARD) has confirmed a case of bovine tuberculosis (TB) in a dairy herd in Charlevoix County, located west of Michigan’s Modified Accredited Zone (MAZ), where the disease is known to be present in the state’s white-tailed deer population.

(Michigan Department of Agriculture and Rural Development)

According to state officials, the detection followed identification of bovine TB in an adult cow at a USDA Food Safety Inspection Service-inspected processing plant. Through animal traceability efforts, officials traced the animal back to its herd of origin. Subsequent testing of the herd identified additional bovine TB cases.

“This latest detection of bovine TB highlights two important realities: how challenging the disease is to address; and why it is so crucial to use all of our tools for detection to swiftly identify cases and take actions to limit disease spread,” say Nora Wineland, state veterinarian for Michigan. “While finding a newly affected herd is never ideal, this case demonstrates our systems for detection and traceability are working, allowing us to quickly implement measures to protect animal health and public health in Michigan.”

MDARD reports an epidemiological investigation is already underway to determine whether additional cases may be linked to the affected herd. There are currently two TB zones within the state: a four-county area in northern lower Michigan called the Modified Accredited Zone, and the remainder of the state’s 83 counties is referred to as the Accredited Free Zone.

This is Michigan’s second confirmed bovine TB case in the past 13 months. The previous case was identified in a beef herd in Alcona County, located within the state’s Modified Accredited Zone, in January 2025. With this latest detection, a total of 84 cattle herds have been confirmed with bovine TB in Michigan since 1998.

What is Bovine Tuberculosis?

According to USDA’s Animal and Plant Health Inspection Service (APHIS), bovine tuberculosis is a chronic bacterial disease that can infect all mammals, including humans. It is caused by the bacterium Mycobacterium bovis and spreads through both direct contact between infected and uninfected animals and indirect exposure, such as contaminated feed, water or the environment.

The disease progresses slowly, often developing over several years. Infection typically begins in the lymph nodes before advancing to the lungs and chest cavity, where it can cause serious lesions.

While cattle are the primary host, the disease can also be present in white-tailed deer and elk, as well as bison, goats and certain carnivores, including coyotes.

The Symptoms

Unfortunately, infected cattle are typically asymptomatic. Detection usually occurs during live animal skin testing or, more commonly, at slaughter through our national slaughter surveillance program, according to USDA. If cattle or bison show clinical signs of tuberculosis, the disease has advanced to affect multiple organ systems, which is rare.

Can it be Prevented?

Bovine TB most often spreads through close contact, especially nose-to-nose interaction between animals, or when cattle consume feed or water that’s been contaminated. In most cases, herds become infected one of two ways: by bringing in an infected animal or through exposure to infected wildlife.

While the prevalence of tuberculosis in cattle is extremely low in the U.S., with an estimated prevalence of 7 per 1 million cattle screened, it can occur. Producers should work alongside their veterinarian to help create a biosecurity plan.

How is it Identified?

According to APHIS, the primary source of tuberculosis surveillance is carcass inspection at all federal and state inspected slaughter establishments. The other main sources of tuberculosis detection are testing animals before interstate movement and during disease investigations. Live animal testing is performed with a screening test. If positive, the regulatory veterinarian will conduct a confirmatory test.

Can it be Treated?

Unfortunately, tuberculosis in livestock is not a treatable disease. When health officials find tuberculosis in a herd, it is managed by either depopulating the herd or by testing and removing reactor animals.

Prepping Dairies for the Return of the New World Screwworm

Mon, 05 Jan 2026 22:00:59 GMT

As New World screwworm moves closer to the southern U.S., dairy farmers, veterinarians and industry leaders are paying closer attention. While it’s not time to panic yet, there is a shared focus on being prepared if the pest crosses the border.

Keith Poulsen, Ph.D., director of the Wisconsin Veterinary Diagnostic Laboratory at the University of Wisconsin, explained the urgency during a recent “Professional Dairy Producers” webinar.

“This is not just another fly,” Poulsen says. “The New World screwworm is the larval stage of a fly that actually burrows into live tissue. That’s what makes it unique and what makes it a genuine threat to cattle, other livestock and even people.”

The U.S. successfully eradicated the screwworm in 1960 using a method called the sterile insect technique. This approach involved breeding and releasing millions of sterile male flies into the wild. When these sterile males mated with wild females, no offspring were produced, slowly shrinking the screwworm population. Over time, this effort drove the pest out of the country.

“It took decades, but we pushed screwworm out of North America all the way into South America,” Poulsen explains.

Today, detections moving north through Mexico have veterinarians and animal health officials paying close attention. With confirmed cases now within roughly 70 miles of the Texas border, the concern is very real.

“We’ve seen this pest before,” Poulsen says. “The fact that it’s moving north again means we need to be ready.”

Why is This Fly Different?

Unlike flies that target manure or dead tissue, the New World screwworm lays eggs in living animals. When those eggs hatch, the larvae burrow into the tissue and feed, creating painful wounds that can rapidly worsen.

“They’re irritated because it’s painful,” Poulsen explains. “When those eggs hatch and the larvae start feeding, it creates abscesses. Abscesses are painful, and they can lead to sepsis or a generalized infection.”

Animal deaths aren’t usually common, but the damage does not need to be fatal to be costly. Livestock often lose condition, require treatment and can suffer carcass trimming or condemnation later.

“You might see it at slaughter when tissue has to be trimmed out or carcasses are condemned,” Poulsen says. “That’s where a lot of the economic impact shows up.”

What Should You Look For?

Poulsen stresses early detection depends less on new technology and more on careful observation. The good news is producers already do this every day.

“We call it active observational surveillance,” he says. “You already check your animals every day. Now you just add a heightened awareness for very specific signs.”

Producers should watch for changes in behavior, skin condition and overall comfort, including:

Unusual discomfort or behavior, such as head shaking, kicking at the body, tail swishing or animals isolating themselves from the group
Animals that just seem off, even if no obvious wound is visible at first
Open sores or abscesses, especially those that appear suddenly or worsen quickly
Foul smelling wounds, which can indicate infected or abscessed tissue
Clusters of lesions, rather than a single isolated wound. “You’ll often see chains of abscesses,” Poulsen explains. “They can range from blueberry sized to golf ball sized, and you’ll usually see more than one.”

Certain areas of the body deserve extra attention, particularly places animals struggle to brush flies away, including:

Udder cleft and teat base
Axilla or armpit area
Neck and dewlap
Along the topline or shoulders

In more advanced cases, larvae can be visible within the wound.

“If you see larvae or maggots coming out, that’s a real telltale sign,” Poulsen adds.

Identifying the Fly

Adult screwworm flies look different from common horn flies, but Poulsen cautions against relying on visual identification alone.

“They have a metallic green body, large heads and striping on the abdomen,” he says. “But it’s hard to tell for sure just by looking.”

(USDA Animal and Plant Health Inspection Service)

Instead, he encourages producers to involve their veterinarian and diagnostic labs early rather than trying to make the call themselves.

“If you think you see the flies, grab a couple, put them in a collection vial and give them to your veterinarian,” Poulsen says. “We’ll identify them for free. Our lab network is activated and trained to look for this.”

Is This Only a Southern Concern?

Texas and the broader Southwest face the highest risk because warm temperatures allow screwworm flies to survive year-round, giving the pest more opportunity to reproduce and spread. Still, Poulsen cautions that northern states should not assume they are completely safe.

“We move a lot of animals back and forth,” he says. “Wisconsin alone moves about 6,000 animals per month to and from Texas.”

Transporting calves south or bringing in animals from higher-risk areas can inadvertently introduce screwworm to northern herds. Even healthy-looking animals can carry early-stage larvae that are not yet visible.

“The risk up here isn’t zero, but it’s not as high as in the south,” Poulsen says. “The advice for those farms is simple. Look closely. If you see anything, say something.”

Cold weather slows screwworm activity, giving farms some seasonal relief. Still, producers need to stay alert as warmer weather returns.

“Now that we’re in the middle of winter, flies shouldn’t be an issue,” he says. “This season is more about keeping an eye out and staying ready for what spring might bring.”

What Happens if Screwworm Crosses the Border?

While no one can say exactly how regulatory responses would play out if screwworm returns, agencies are already preparing.

Federal and state animal health officials are increasing surveillance, testing and monitoring programs to catch the pest early. Rapid response plans are also being developed, including quarantine measures, movement restrictions and treatment strategies.

“We’re ramping up testing, education and surveillance,” Poulsen says. “It’s not just about detecting insect presence. It’s about rapid response, communication and ensuring we have animal movement protocols ready if needed.”

Public health is also involved.

“We had a human case in Maryland from someone who traveled to an endemic area,” he adds. “Public health found it, treated it and contained it. That tells me the system works, but we still don’t want it in our livestock.”

Making Biosecurity a Priority

Being proactive isn’t just about one pest. Recent research presented at the MILK Business Conference shows many U.S. dairy farms take a reactive approach to biosecurity, leaving operations vulnerable to evolving disease threats. About one-third of farms don’t regularly review their biosecurity plans, even as challenges like highly pathogenic avian influenza, bovine spongiform encephalopathy and New World screwworm continue to emerge.

The survey of more than 300 dairy producers found that while 68% of larger farms have a biosecurity plan, 34% do not review or update it regularly. The good news is that more than 70% of large dairies are working on improvements, showing parts of the industry are taking biosecurity seriously. Having these systems in place can make a real difference when it comes to spotting problems like screwworm early and responding quickly.

Awareness Over Alarm

Poulsen is quick to clarify that being prepared does not mean panicking. While screwworm has not been detected in U.S. livestock yet, thinking ahead can make all the difference.

“If animals are coming from a high-risk area, they may need to be treated before transport and monitored closely after arrival,” he says. On modern dairies, that is easier said than done because quarantine takes space and space costs money. That is why he encourages producers to start planning now.

“Talk to your veterinarian,” he says. “Ask what your biosecurity plan looks like if you have to bring animals in. Do you have a place to isolate them? How long would they stay there? What treatments would you use?”

He emphasizes that the goal is not fear but knowledge and readiness.

“This isn’t about fear. It’s about knowing what we’re up against and using every resource we have to protect our animals and our industry.”

While the threat of New World screwworm seems intimidating, Poulsen’s advice is simple. Keep up with the latest updates, pay close attention to your animals and reach out to your vet or state animal health officials sooner rather than later. Staying ahead now makes all the difference later.

“The consequence of missing it is very, very high,” Poulsen adds. “It is much easier to control it early than later.”

Looking ahead, he sees the current situation as the start of a longer process.

“We’re at the beginning of this, not the end,” Poulsen says. “That’s exactly why we’re having these conversations now.”

How to Keep Birds Out of Barns

Mon, 29 Dec 2025 22:52:35 GMT

A few birds might not seem like a big deal, but unmanaged populations can quickly create real problems on a dairy. From feed loss to biosecurity concerns, birds can put herd health and even profitability at risk.

While there’s no perfect solution for ridding dairies of birds, control starts with understanding what’s legally allowed, taking timely action and using multiple strategies consistently. Starting early and applying consistent measures helps prevent issues before they escalate and creates conditions that make barns less appealing to these nuisance pests.

How Much Damage Can Birds Cause?

Bird-related damage and feed waste can be substantial, particularly when large flocks are present. Research from the University of Kentucky indicates a single European starling consumes approximately 0.0625 lb. of feed per day. While that amount might not seem like a lot, it can add up quickly. A flock of 10,000 birds can consume up to 500 lb. of feed daily, resulting in significant losses over time.

According to Matthew Springer, wildlife specialist, and Donna Amaral-Phillips, dairy Extension specialist, the impact extends beyond feed loss. Birds often target high-nutrient components of the ration, leaving behind an unbalanced mix. This inconsistency can negatively affect intake and animal performance, even when feed delivery is otherwise well managed.

Bird droppings are another headache. Manure from roosting birds can contaminate feed bunks, waters and barn surfaces, increasing the risk of disease transmission. When they have easy access to feed and housing areas, they can create added biosecurity challenges. Birds are known carriers of E. coli and Salmonella and can potentially carry highly pathogenic avian influenza (HPAI), or bird flu. Working to keep these pests out of barns can help protect herd health and reduce the risk of disease.

Know the Legal Limits

Before taking steps to manage birds, producers need to understand the legal requirements that govern control methods. Bird control is regulated by state and federal law, so it is important to check with your state wildlife division before creating a control plan.

Many bird species are legally protected, so it’s important to know the rules before taking action. It is illegal to kill or harm protected birds without a permit, and you cannot disturb nests that contain eggs or young. If your control measures could affect these species, you’ll need a Migratory Bird Depredation Permit from the U.S. Fish and Wildlife Service, often obtained with help from USDA-APHIS Wildlife Services. Starting with your state wildlife agency can save headaches later and keep your plan within the rules.

Start With Prevention and Timing

Bird control works best when prevention starts early and is adjusted throughout the year. Even during winter, acting quickly can keep birds from settling in and establishing roosts that are harder to remove later.

Focus winter prevention efforts on:

Sealing gaps around vents, eaves and rooflines
Keeping feed areas clean and covered
Installing plastic strip curtains on doors to limit entry

Birds tend to stick around when they find an easy meal, so limiting access to feed is essential. To reduce feed-related attractants:

Clean up spilled feed daily
Store minerals and additives in sealed bins when possible
Keep commodity bays tidy and sweep up loose feed regularly

Water can also attract birds. If they can drink or bathe in waterers, they are more likely to stay.

Prevent birds from perching on waterer edges
Adjust water levels so birds can’t easily reach the water
Clean waterers frequently to remove debris and droppings

Exclusion and Netting

Keeping birds out of barns is one of the most effective long-term strategies, but it takes planning and persistence. Because barns need airflow and room for equipment, completely sealing them isn’t always practical. Instead, focus on improving the spots birds are most likely to use.

Some practical ways to keep birds out include:

Closing gaps around vents, eaves and rooflines
Hanging plastic strip curtains on doors to limit entry
Using netting in areas where birds tend to roost or nest

Plastic strip curtains are especially helpful because they let people and equipment pass through while keeping birds out. Any openings larger than half an inch around vents, eaves and lofts should be blocked with wood, metal or wire mesh. These steps won’t get rid of every bird, but they can go a long way toward reducing roosting and nesting in barns.

Make Roosting Sites Uncomfortable

Birds prefer flat surfaces for perching, so changing those surfaces can make barns less inviting.

Ways to discourage roosting inside the barn:

Alter ledges to angles of 60 degrees or greater
Add angled wood or metal sheathing to problem areas
Install porcupine wire on ledges and rails

Outside the barn, you can also make your property less appealing by:

Thinning tree branches near buildings to remove perch sites
Reducing wind protection that shelters birds, encouraging them to move elsewhere

Scare Tactics Require Persistence

Visual scare devices and distress calls can help discourage birds, but they must be changed regularly. Birds quickly become accustomed to static deterrents. Combining visual and sound deterrents and rotating them throughout the year improves effectiveness.

Examples of scare tactics include:

• Reflective tape or colored flags
• Flashing or revolving lights
• Distress calls or AM/FM radios
• Wind chimes or loud noises
• Replicas of hawks, owls or snakes

A Year-Round Commitment

Birds are a persistent nuisance on farms, and their presence can affect everything from feed quality to overall herd health. Unfortunately, there is no perfect solution to eliminate them completely, so managing their numbers and keeping them out of barns requires attention year-round. The most effective programs start early, use a mix of strategies and adjust seasonally as bird activity changes.

First Case of Avian Flu Detected in Wisconsin Dairy Herd

Sun, 14 Dec 2025 19:40:26 GMT

A case of highly pathogenic avian influenza (HPAI) has been detected in a dairy herd in Dodge County, Wisconsin, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) announced Sunday. This marks the first confirmed detection of the virus in dairy cattle in the state.

The herd was identified through routine National Milk Testing Strategy screening, not the surveillance required for moving cattle across state lines. The affected farm has been quarantined, and any cattle showing signs of illness are being separated for treatment.

Bird flu has already been detected in poultry flocks in Wisconsin. On Dec. 9, state officials reported HPAI in a flock in Marquette County, which is just one county away from the affected dairy herd.

HPAI in dairy cattle has been documented in the U.S. before, with the first detections reported in March 2024 in dairy herds in Texas and Kansas. Since then, there have been more than 1,000 confirmed cases across 18 states, primarily through targeted testing and monitoring programs. While the pace of new detections has slowed in recent months, one additional confirmed case has been reported in California within the past 30 days, indicating the virus is still a threat.

A Wake-Up Call for Dairy Biosecurity

The Wisconsin case comes as new research from Farm Journal highlights ongoing gaps in dairy biosecurity practices nationwide. A survey of more than 300 dairy producers, presented at the MILK Business Conference, found that while many operations report having biosecurity plans in place, consistent implementation and regular review remain a challenge.

According to the survey, 68% of farms with at least 250 cows say they have a biosecurity plan, yet 34% of those producers acknowledge they do not routinely review or update it. The findings point to vulnerabilities at a time when disease threats such as HPAI, New World screwworm and bovine spongiform encephalopathy continue to raise concern across the livestock sector.

(Farm Journal)

“We need biosecurity efforts to be more impactful at the ground level,” said Kirk Ramsey, professional services veterinarian with Neogen, who reviewed the survey results. “Not only to prevent major outbreaks, but also to protect employees and families from what could be carried home every day.”

As emerging diseases continue to challenge dairy operations, the research reinforces the importance of consistent, practical biosecurity measures to reduce risk and protect herd health.

What are the Symptoms of HPAI in Dairy Cattle?

As monitoring continues, officials are urging producers to stay alert for early signs of illness within their herds, as prompt detection and response remain key to limiting further spread. Signs of HPAI include:

Drop in milk production
Loss of appetite
Changes in manure consistency
Thickened or colostrum-like milk
Low-grade fever

State officials are monitoring the situation and working closely with the farm to contain the virus and prevent further spread. DATCP emphasized there is no concern for the safety of the commercial milk supply, as pasteurization eliminates the virus. The CDC considers the human health risk low.

Enhancing Biosecurity on Calf Ranches: Balancing Animal and Human Health

Fri, 15 Aug 2025 13:09:46 GMT

When it comes to biosecurity on calf ranches there are two main components: preventing disease spread among animals and safeguarding human health. While often the focus is on animal health, it’s crucial to remember the significant role humans play in disease transmission and prevention. Kirk Ramsey, veterinarian for Neogen, underscores the importance of biosecurity on calf ranches needing to involve those two main components and notes that implementing a comprehensive biosecurity strategy can help achieve a balanced approach.

In Deerfield, Kan., Kansas Dairy Development provides temporary housing for more than 96,000 head of cattle, from a few days old to springers nearly ready to calve, and according to Jason Shamburg, the organization’s co-founder and CEO, great animal care and husbandry go hand in hand with biosecurity.

“Clean cattle trailers, very clean facilities, clean calf hutches, clean bedding, clean milk, clean coveralls for our team and practices such as individual needle changes for treatments and needless applications for vaccines as well as a robust BVD screening and surveillance program are just some of the aspects that we believe develop a great calf but also creates the overall benefits of bio security,” he says.

Ramsey concurs but also notes sometimes a two-part viewpoint is overlooked at calf ranches because so much focus is put toward the calves when they are first onboarding into a new facility.

“Often they come from multiple states and go straight into calf hutches or individual pens,” he says. “In a way, this is kind of like a biosecurity practice to create a little bit of separation based on where those calves are coming from.”

Calf Health Management
Ramsey provides some tips on overall biosecurity tips for both calves and employees for calf ranches.

Onboarding
When calves arrive at ranches from various locations, biosecurity practices such as keeping calves separated in their hutches can create a needed barrier against disease. Maintaining organization based on the origin of the calves helps monitor and control potential disease spread.

“Also making sure those calves have had that first feeding is a massive part of their movement forward. Getting them comfortable and settled is a big first step.”

Sanitation Practices
Before new groups of calves are introduced, sanitation of the hutches is essential. Best practices involve pressure washing and using a combination of soap and disinfectants to clean the hutches. Air drying under the sun can further sanitize the environment. Moving hutches to new bedding areas allows the old ground to naturally sanitize and prepare for future use.

“A best recommendation practice is always moving hutches as you go down the line, so the calves are actually never on a bed pack where they were prior.”

Pest Control
Seasonal challenges, such as fly infestations in the summer, require strategic pest control measures. Ensuring dry bedding and routine sanitation practices can significantly reduce pest-associated risks. Careful maintenance of feeding areas, including bucket cleaning, can help control pest populations.

“Anything that we can do to try to maintain a drier environment in that calf hutch, the better to try to inhibit as much fly growth,” he says, noting the areas around where those flies are growing should be the target. “So that’s in front of those calf hutches, where that milk is getting spilled, where a lot of that fly growth is occurring.”

Record Keeping and Communication
Accurate record-keeping of calf health, vaccination schedules and treatments forms the foundation for effective biosecurity measures. Clear communication across all levels of staff ensures consistent implementation of biosecurity protocols, enhancing overall herd health.

“Having one person in charge of that line, or that group of lines, keeps that person responsible for those calves,” he says. “That person knows everything about those calves for that period of time, and then when they move to the next line, they are a communication relayer.”

Waste Management and Environmental Hygiene
Efficient waste management involves cleaning manure and bedding, allowing ample exposure to sunlight for natural ground sterilization. This ensures the environment is prepared for new calves, reducing the likelihood of disease resurgence.

“Allowing the sunlight to do its job, to break down the bacteria, is vital.”

Staff Training and Human Biosecurity
Another huge element to biosecurity is the people that interface with the cattle. It’s important to ask what are we doing to prevent each other from having the interface and bringing some of that stuff home to our families?

Providing coveralls and rubber boots can help reduce the risk of disease transmission to and from home environments. Encouraging routines like washing boots and hands is an easy yet impactful biosecurity measure.

Implementing comprehensive biosecurity measures on calf ranches fortifies the health of calves while protecting human health. Simple practices, such as maintaining cleanliness, systematic organization and thorough communication, can collectively elevate the biosecurity standard. Emphasizing these strategies ensures a healthier and more productive calf-raising environment.

As we aim for improved biosecurity measures, understanding both the challenges and solutions will pave the way for better practices on calf ranches, ultimately creating a win-win situation for both calves and humans.

8 Easy, Cost-Effective Tips To Maximize Biosecurity On The Farm And At The Fair This Summer

Wed, 30 Jul 2025 16:32:36 GMT

When it comes to biosecurity, livestock producers should have protocols in place for both on the farm and when taking animals to fairs or exhibitions. Live animals, vehicles, equipment, animal products and people can carry disease onto farms.

University of Missouri Extension dairy specialist Chloe Collins says preparation helps producers know what they are up against.

“This will help your biosecurity practices run smoothly and effectively,” she says.

With it being county and state fair season for many parts of the country, University of Missouri Extension veterinarian Corinne Bromfield says there are easy things producers can do to improve biosecurity and help minimize transmission of diseases.

“Many think biosecurity needs to be intense and expensive, but small, consistent actions can pay big dividends,” Bromfield says.

Collins and Bromfield share basic biosecurity steps that cost little to nothing but can save a lot of money and headaches:

Check health requirements for exhibitions. Many events require a Certificate of Veterinary Inspection (CVI), or health certificate from a veterinarian — especially for livestock traveling from out of state. This helps ensure only healthy animals go to shows, reducing the likelihood animals will pick up something at the show and bring it back home. If livestock exhibit any signs of contagious disease, such as coughing, diarrhea or skin irritations, they should be left at home.

Dedicated clothing. People taking animals to fairs should wear dedicated clothing and footwear at the fair and not bring them home to their other animals. Having dedicated clothing/footwear that doesn’t leave your farm is also important for your animals staying home.

Isolate new or returning animals. This is a key step to mitigate the immediate spread of disease and gives producers time to observe animals. Make sure the isolation area is separate from high-traffic areas and has its own feed and water sources. Another option is attending a terminal show, where the livestock will not return to the home herd.

Set a quarantine protocol. Keep new or returning animals separate from the herd for at least two weeks (four weeks is even better), and watch for any signs of illness. This helps prevent the spread of disease to animals that are currently healthy animals. Work with your quarantined after working with the home herd.

Sanitize. Keep housing, feeding and watering areas clean. Regularly disinfect these spaces and remove manure frequently to reduce cross contamination. Avoid bringing home feed, shavings or manure from the event. Wash the trailer to clean off manure, and always wash your hands after interacting with animals.

Clean your equipment. This is especially important for those attending fairs this summer or frequently moving animals. Always clean your equipment before you leave the farm and as soon as you return. If you’re bringing new equipment, such as a stock trailer, to the farm, stop at a truck wash on the way home to clean and disinfect it. Don’t forget to scrub buckets, fans, panels, shovels and any other objects that have traveled with your animal or may have encountered other animals or animal products.

Limit farm access. Create designated areas for visitors. If you frequently have people who visit your farm, create zones for them — preferably away from animal areas. Require visitors to wear disposable footwear covers (like plastic boots) to limit disease spread. Designate parking and foot traffic areas to keep a barrier from your herd. Consider posting “Personnel Only” signs and establish protocols for high-risk areas, such as feed storage and highly trafficked zones.

Develop a written biosecurity plan unique to your farm. First, figure out what risks you already face with visitors, moving equipment on and off the farm and other animals that could be potential disease vectors. Plan how to mitigate animal contact and minimize risks.

New World Screwworm Facts

Thu, 19 Jun 2025 14:24:55 GMT

A resurgent livestock pest has been making a lot of headlines lately.

The New World screwworm (NWS) was eradicated from the U.S. in the 1960’s, according to Extension educators at Texas A&M University. In a recently published bulletin , they noted there are occasionally flare-ups of the pest in Central America and Mexico.

Currently there is an NWS outbreak in progress in Central America. U.S. Secretary of Agriculture Brooke Rollins recently closed the border to livestock imports from Mexico after learning the pest was detected less than 700 miles from the U.S.-Mexico border. The ban applies to imports of cattle, horses, and bison, although NWS attacks all warm-blooded species, including wildlife and humans.

The screwworm gets its name from the unusual feeding behavior of its larvae (maggots) that “screw” into the host’s tissue with sharp mouth hooks. Over time and continued larval feeding and reproduction, these wounds become larger and deeper, causing extreme pain, tissue damage, and sometimes even death.

The Texas A&M educators advise producers to regularly check their livestock for potential NWS infestation. Symptoms include:

Foul-smelling wounds with visible maggots;
Animals biting and licking at wounds;
Lesions in navels, ears, and dehorning and branding sites; and
Unusual restlessness or lethargy.

They shared that typical livestock insecticide treatments may not contain an NWS outbreak because of the difficulty in targeting wildlife for treatment. In the past, the only way outbreaks have been brought under control is via release of sterile males, known as the sterile insect technique (SIT).

Producers who suspect a case of NWS infestation should immediately quarantine affected animals and report the case to their local veterinarian or wildlife biologist.

Hungary Confirms Foot-and-Mouth Disease Outbreak in Cattle

Fri, 07 Mar 2025 22:43:18 GMT

Hungary reported its first case of foot-and-mouth disease in more than 50 years, on a cattle farm in the northwest of the country, the World Organization for Animal Health (WOAH) said, citing Hungarian authorities on March 7.

According to WOAH, the outbreak, discovered in the city of Gyor, is the first outbreak of foot-and-mouth disease outbreak reported since 1973. The case was found on a 1,400-strong cattle farm on the border with Slovakia, Hungary’s National Food Chain Safety Office (Nébih) reported on Friday .

The farm showed classic symptoms of foot-and-mouth disease at the beginning of March, the report says.

“The presence of the pathogen was confirmed by the Nébih laboratory, which is why Dr. Szabolcs Pásztor, the national chief veterinarian, immediately ordered the closure of the farm and the initiation of an epidemiological investigation,” the report says. " In order to prevent the further spread of the disease, extremely strict official measures will be implemented, including a ban on the transport of susceptible live animal species.”

On Jan. 10, Germany confirmed its first outbreak of foot-and-mouth disease since 1988. The outbreak was detected in a herd of water buffalo in the Märkisch-Oderland district of Brandenburg, near Berlin.

“The confirmation of foot-and-mouth disease in cattle in Hungary comes less than two months after the virus was found in water buffalo in Germany,” the Swine Health Information Center (SHIC) said in a statement. “Hungary does not share a border with Germany; FMD-affected animals are approximately 475 miles apart.”

FMD affects cloven-hoofed animals such as cattle, pigs, sheep and goats. Not only is it highly contagious, but it also causes severe symptoms, including fever, painful blisters, reduced milk production and significant economic losses for farmers.

FMD poses no direct health risk to humans, but it’s important to note that they can act as carriers of the virus via contaminated clothing, shoes or equipment.

Trump Administration Announces $1 Billion to Combat Avian Flu and Soaring Egg Prices

Wed, 26 Feb 2025 15:28:34 GMT

The Trump administration is investing up to $1 billion in new funding to combat impacts of highly pathogenic avian influenza (HPAI) and soaring egg prices.

USDA Secretary Brooke Rollins in the Wall Street Journal said, “There’s no silver bullet to eradicating avian flu.” She laid out a five-point plan to address the situation.

Dedicate up to $500 million to helping U.S. poultry producers implement “gold-standard” biosecurity measures. USDA has developed a successful pilot program, called Wildlife Biosecurity Assessments, to identify and implement more safety measures. USDA will pay up to 75% of the cost to address any identified biosecurity vulnerabilities at poultry farms.
Make up to $400 million of increased financial relief available to farmers whose flocks are affected by avian flu, and we will assist them in receiving faster approval to begin safe operations again after an outbreak.
USDA is exploring the use of vaccines and therapeutics for laying chickens. While vaccines aren’t a stand-alone solution, we will provide up to $100 million in research and development of vaccines and therapeutics, to improve their efficacy and efficiency. This should help reduce the need to “depopulate” flocks, which means killing chickens on a farm where there’s an outbreak. Note: USDA hasn’t yet authorized the use of a vaccine. Before making a determination, USDA will consult state leaders, poultry and dairy farmers, and public-health professionals. The agency will also work with trading partners to minimize potential negative trade effects for U.S. producers and to assess public-health concerns.
USDA will take other actions to lower the price of eggs. For starters, it will remove unnecessary regulatory burdens on egg producers where possible. This will include examining the best way to protect farmers from overly prescriptive state laws, such as California’s Proposition 12, which established minimum space requirements for egg-laying hens.
USDA will consider temporary import options to reduce egg costs in the short term. We will proceed with imports only if the eggs meet stringent U.S. safety standards and if we determine that doing so won’t jeopardize American farmers’ access to markets in the future.

Senate Ag Committee Chair John Boozman (R-Ark.) said, “Producers and consumers alike have experienced the economic burden of this outbreak since 2022. I applaud Secretary Rollins and the Trump administration for prioritizing a strategy to combat this evolving threat. I look forward to working with USDA to ensure all poultry and livestock producers’ unique challenges are taken into consideration and they have the tools they need to address animal disease risks.”

In the Wall Street Journal Op-Ed , Rollins said some of the money will come from cuts to USDA spending by the Department of Government Efficiency (DOGE).

“Egg prices are skyrocketing, and it isn’t simply a matter of inflation. Grocery prices rose by more than 20% on President Biden’s watch, but the average price of a dozen eggs went up 237%, from $1.47 in January 2021 to $4.95 last month,” Rollins said wrote in the Wall Street Journal. “This matters for American families because eggs are a healthy, accessible and generally affordable source of protein.”

By the Numbers: Soaring Egg Prices
USDA upped its 2025 egg price forecast to a 41.1% increase (range of up 15.0% to 74.9%), more than double the 20.3% rise they forecast in January. USDA started their 2025 egg price forecast in July 2024 looking for them to decline 7.6% versus 2024

“Retail egg prices increased by 13.8% in January 2025 after rising by 8.4% in December 2024,” USDA detailed. “Retail egg prices continue to experience volatile month-to-month changes due to an outbreak of HPAI that began in 2022. HPAI contributes to elevated egg prices by reducing egg-layer flocks and egg production. About 18.8 million commercial egg layers were affected by HPAI in January 2025, the highest monthly total since the outbreak began in 2022.”

Egg prices in January were 53% higher than January 2024 and “surpassed the previous peak prices in January 2023,” USDA detailed.

I just left a message for Chris Kempczinski, CEO of McDonalds USA, thanking him for the choice to not add surcharge to eggs. THANK YOU @McDonalds!!!

Avian Flu a Top Priority for Rollins
On Monday, Rollins met with poultry farmers and industry leaders in Texas to address the ongoing avian flu crisis. She toured a Cal-Maine Foods facility in Bogata before hosting a roundtable in Mount Pleasant, where discussions focused on outbreak response and mitigation strategies. Rollins criticized the Biden administration’s handling of the issue, emphasizing the Trump administration’s commitment to supporting farmers and stabilizing egg prices.

“Clearly, this is a massive issue for our poultry producers, especially our egg layers,” Rollins told AgriTalk’s Chip Flory, in an exclusive interview, during Top Producer Summit. “Ensuring that we have a plan, not just for the short-term to bring down egg prices, which the president is very focused on, but for the long-term. What are the best practices around the world? Why in America have we been hit so hard? Why did the last USDA, a couple of years ago, recognize it as a major issue, but not many steps were taken.”

Just hours after being confirmed, Rollins’ first official meeting at the White House was on avian flu. She told Flory it’s her top priority right now, and she’s gathered a team from within USDA and the White House to focus on the issue.

“I’ve been talking to governors. I’ve been talking to the companies that are facing this. I’ve been talking to grocery. I mean, we’ve been talking to everyone, trying to come up with a big toolkit to be able to really approach this and hopefully figure out a way to, again, solve it for the long-term,” Rollins said.

Flory followed up by asking Rollins if vaccines will be one of the tools used by USDA.

“Vaccines are being discussed right now. I think that there is a lot of opinion on that on both sides. And we’re working through all of that right now,” Rollins told Flory.

The big announcement released on Wednesday did not include any plans to approve vaccines to combat the disease.

APHIS Answers Call to Protect Animal Agriculture

Thu, 16 Jan 2025 21:00:13 GMT

Despite facing many challenges, including the continued response to highly pathogenic avian influenza, USDA’s Animal and Plant Health Inspection Services (APHIS) worked to protect the health and value of America’s agricultural and natural resources.

“2024 was a year that confronted APHIS with new challenges. It was a year that forced us to find new and creative solutions to animal and plant health threats,” says Michael Watson, administrator for APHIS, in the 2024 Impact Report.

Here are a few highlights from the 2024 Impact Report surrounding animal agriculture:

Confirmed the first detection of HPAI H5N1 in a dairy herd in March 2024, and subsequently identified, investigated, and responded to H5N1 detections in livestock in over 860 herds across 17 states. APHIS issued two federal orders, implemented a producer support program, set up a voluntary monitoring and surveillance program for interested producers, and developed a national bulk milk testing strategy to help states protect the health of their dairy herds.
- Opened new market access for American agricultural exports, including U.S. rice to Ecuador, Texas grapefruit to South Korea, and California peaches and nectarines to Vietnam. APHIS also opened markets for U.S. live cattle, day-old chicks, and hatching eggs to Mozambique and beef and bone meal to Ecuador and Peru.
- Worked with regional partners in Central America to implement a multilateral response to the New World screwworm outbreak, increasing production of sterile flies weekly from 20 million to 90 million. These efforts, combined with rigorous surveillance and livestock inspections, protected U.S. borders from this devastating pest.
- Provided assistance to livestock producers on more than 123,000 occasions, including outreach and direct control activities to protect livestock from predation through a combination of techniques and tools. As much as possible, we responded using nonlethal methods like range riding, fladry, fencing, and husbandry practices.
Continued an emergency program to address nationwide detections of highly pathogenic avian influenza (HPAI). Since the outbreak began in February 2022, we have confirmed the virus in over 1,300 poultry premises across the nation and supported affected producers through depopulation, disposal, and indemnification programs.
Protected American agriculture from harmful plant pests and foreign animal diseases by intercepting 289,855 prohibited agricultural items and 3,008 quarantine-significant pests during baggage inspections. These inspections involved more than 16.7 million passengers bound for the U.S. mainland from Hawaii and Puerto Rico.

An Update on Foot-and-Mouth Disease Virus Serotype O in Germany

Wed, 15 Jan 2025 16:29:29 GMT

On Jan. 10, Germany confirmed its first outbreak of foot-and-mouth disease virus (FMDV) since 1988. The outbreak was detected in a herd of water buffalo in the Märkisch-Oderland district of Brandenburg, near Berlin.

“Water buffalo, introduced to Germany in the 1990s, are farmed for milk, meat, and grassland maintenance,” according to a summary by the team at the Center for Animal Health and Food Safety (CAHFS) . They prepared a summary of the current FMDV situation in Germany for the Swine Health Information Center (SHIC) as part of the SHIC Global Swine Disease Monitoring Reports.

Here are some key points:

Within the affected water buffalo herd, three infected buffalo died and the remaining herd of 11 animals was euthanized to contain the disease.
Authorities have implemented strict control measures, including the establishment of a 3 km exclusion zone and a 10 km monitoring zone, and are conducting investigations to determine the source and route of the infection.
Immediate actions included culling all susceptible animals within a 1 km radius, including a farm with 170 pigs and another location with 55 goats, sheep, and three cattle as a precaution.
A transport ban for livestock was imposed across Brandenburg and later extended to Berlin, lasting at least 72 hours.
Sampling of animals within a 3 km radius is ongoing to assess the outbreak’s spread.

Serotype O
The Friedrich Loeffler Institute (FLI) identified the FMD virus as serotype O, a strain commonly found in the Middle East and Asia. Although, the exact route of entry remains unclear, the report says.

“The affected farm operates organically, using only its own hay for feed. The outbreak highlights the ongoing risk of FMD introduction into the EU through illegal trade and travel-related movement of animal products from FMD-endemic regions,” the report explains.

Germany, previously recognized as FMD-free along with the EU, has lost its status, triggering trade restrictions. Because of this, South Korea banned the import of German pork and quarantined 360 tons imported since December 27 for testing.

At the Green Week Agricultural Fair in Berlin, cloven-hoofed animals were excluded to mitigate risks.
In the Netherlands, 125 farms that recently imported calves from Brandenburg were ordered to suspend operations, and a nationwide standstill on calf transport was implemented until January 19.
Veal calf imports from Brandenburg were also banned.
Export to countries within the European Union’s single market is still possible for products that originate outside the restricted zones, under the principle of regionalization.

Germany’s FMD antigen bank, established for emergencies like this, holds serotype-specific vaccines and can produce them within days, the report says. Vaccines must be tailored precisely to the specific serotypen because vaccines against other strains are ineffective.

FMD affects cloven-hoofed animals such as cattle, pigs, sheep and goats. Not only is it highly contagious, but it also causes severe symptoms, including fever, painful blisters, reduced milk production and significant economic losses for farmers.

FMD poses no direct health risk to humans, but it’s important to note that they can act as carriers of the virus via contaminated clothing, shoes or equipment.

“Past outbreaks in Europe, such as those in the UK (2007) and Bulgaria (2011), resulted in extensive culling of livestock to control the disease,” the report says. “The current outbreak underscores the importance of biosecurity measures, rapid response and vigilance to protect agriculture and livestock from this economically devastating disease.”

Summary of New FMDV Strains into New Territories (2022 to date):

2022
Egypt: South American strains A/EURO-SA, and O/EURO-SA, were isolated from a batch of Egyptian samples tested by the World Reference Laboratory (WRLFMD).

Libya: FMD virus O/EA-3, a strain from East Africa was detected.

Iraq: FMD virus SAT2/XIV, closely related to viruses from Ethiopia was detected. It was observed to cause more severe clinical disease.

Jordan: FMD virus SAT2/XIV, closely related to viruses from Ethiopia was reported in the country.

Türkiye: FMD virus SAT2/XIV, was reported for the first time.

2023
Qatar: FMDV SAT1/I topotype, a virus with close sequence identity to a virus from Kenya was reported for the first time.

Algeria: Virus of the SAT2 topotype (SAT2/V) detected for the first time. Viruses from this lineage were last found in Ghana (1991), Togo (1990) and Ivory Coast (1990).

2024
Libya: A new incursion of FMDV O/EA-3 which is endemic to East Africa

Türkiye: Re-emergence of a virus strain originally from Iran, FMDV A/ASIA/Iran-05FAR-11

2025
Germany: Recurrence of FMD after 37 years. The National Reference Laboratory at the FLI confirmed the virus Serotype as type O, although the virus strain, origin, and route of entry into Germany are yet to be determined.

German Meat Exports Face Disruption After Foot-and-Mouth Disease Case

Mon, 13 Jan 2025 16:02:47 GMT

Germany’s meat and dairy exports outside the EU face severe restrictions after the country’s first case of the livestock disease foot-and-mouth was confirmed on Friday, the country’s agriculture ministry said.

German authorities confirmed the country’s first outbreak of foot-and-mouth disease in nearly 40 years in a herd of water buffalo on the outskirts of Berlin.

Foot-and-mouth disease causes fever and mouth blisters in cloven-hoofed ruminants such as cattle, swine, sheep and goats and in past decades has required major slaughtering campaigns to eradicate. Measures to contain the highly infectious disease, which poses no danger to humans, are being implemented, German authorities said.

The loss of Germany’s status as free from foot-and-mouth disease under World Organisation for Animal Health requirements, means many veterinary certificates for exports outside the EU can no longer be issued, Germany’s federal agriculture ministry said.

Consequently, exports of milk and dairy products, meat and meat products, hides and skins and blood products are “currently hardly possible”, the ministry said, adding that it “assumed third countries would immediately impose bans on such goods from Germany.”

The immediate goal is to ensure the disease does not spread, German agriculture minister Cem Oezdemir said.

German meat exports to the EU were likely to continue because current rules require exports to be stopped only from the region of an EU country directly suffering from a disease, an agriculture ministry spokesperson said separately.

Some countries are restricting imports of German meat including South Korea, the spokesperson said.

Authorities in Berlin and Brandenburg announced a six-day halt tothe transport for animals which can transmit the disease while investigations into the cause continue.

The president of the association of German farmers Joachim Rukwied called for urgent and intensive action to prevent the disease spreading and causing more serious financial losses for farmers.

The disease occurs regularly in the Middle East and Africa, in some Asian countries and South America.

USDA Reports First H5N1 Detection in Swine

Wed, 30 Oct 2024 23:27:10 GMT

USDA announced on Oct. 30 the first reported case of H5N1 in a pig in an Oregon backyard farm. It’s important to note there is no concern about the safety of the nation’s pork supply as a result of this finding, USDA said. This farm is a non-commercial operation, and the animals were not intended for the commercial food supply.

“The confirmed case in Oregon poses no threat to consumer health or food safety; properly handled and cooked pork products remain safe for consumption,” Bryan Humphreys, National Pork Producers Council (NPPC) CEO said in a statement. “The entire pork industry remains committed to safeguarding food safety and human and animal health.”

The case was discovered on a backyard farm that includes a mix of poultry and livestock, including swine. The Oregon Department of Agriculture announced on Friday, Oct. 25, that poultry on this farm represented the first H5N1 detection in Crook County, Oregon. On Tuesday, Oct. 29, the USDA National Veterinary Services Laboratories also confirmed one of the farm’s five pigs to be infected with H5N1, marking the first detection of H5N1 in swine in the U.S., USDA reports.  

“The livestock and poultry on this farm shared water sources, housing, and equipment; in other states, this combination has enabled transmission between species. Although the swine did not display signs of illness, the Oregon Department of Health and USDA tested the five swine for H5N1 out of an abundance of caution and because of the presence of H5N1 in other animals on the premises,” USDA wrote.

The swine were euthanized to facilitate additional diagnostic analysis. Although test results were negative for two of the pigs, and test results are still pending for two others.  
The farm has been quarantined to prevent further spread of the virus. Other animals on the farm include sheep and goats that remain under surveillance.  

“USDA’s National Veterinary Services Laboratories (NVSL) has conducted genomic sequencing of virus from the poultry infected on this farm, and that sequencing has not identified any changes to the H5N1 virus that would suggest to USDA and CDC that it is more transmissible to humans, indicating that the current risk to the public remains low,” USDA wrote.

H5N1 detections include viral genome sequencing to provide additional information of interest to medical professionals and the research community to improve understanding of the virus. Genetic sequencing for these samples is underway, but results may be inconclusive due to low viral levels in the samples, USDA said.   

Pork Producers Practice Biosecurity to Protect Pigs
Biosecurity is critical to eradicating H5N1 and other viruses. Not only does biosecurity protect the health of livestock, but it also protects the health of farmworkers and their families. For more information on protecting farmworkers, visit the CDC’s website .

The pork industry has worked alongside USDA’s Animal and Plant Health Inspection Service (APHIS) since 2009 to carry out the swine influenza surveillance program to identify influenza viruses circulating in swine, proactively detect reassortment viruses that could impact public health, and gain knowledge to contribute to improved animal health diagnostics and vaccines, NPPC pointed out in a statement.

“Pork producers have always been proactive and diligent about implementing biosecurity plans as part of their daily production practices to assure animals wellbeing and food safety,” Lori Stevermer, NPPC president and Minnesota pork producer said. “This detection serves as a reminder for producers of all sizes to understand and address influenza virus risks.”

What’s Next?
USDA recently approved two vaccine field safety trials for vaccine candidates designed to protect dairy cows from H5N1, and continues to explore vaccine options for other species.   As USDA takes additional steps to protect the health of livestock, it will continue to work closely with CDC to protect the health of people and FDA to protect the safety of the food supply.

“These collective, collaborative efforts have helped protect farmworkers and farmers, the health and welfare of livestock animals, and reaffirmed the safety of the nation’s food supply. The U.S. government remains committed to addressing this situation with urgency,” USDA said.

Navigating HPAI: Supporting Producers and Safeguarding Cows

Mon, 28 Oct 2024 17:04:24 GMT

The first person who will notice illness in the herd is the one who works hands-on with the cows. It’s a cow that just looks off, a drop in production or changes in cow activity and behavior that triggers a call to the vet, monitoring or treating. Treatment is on a case-by-case basis, depending on which cow it is and what’s going on.

But for matters of trade and human health, the health of the entire U.S. herd must be addressed systematically. Rosemary B. Sifford, DVM; Deputy Administrator; USDA Animal and Plant Health Inspection Service says disease monitoring actually looks very similar on the state and national level. “Except, of course, we’re looking across all the herds. In some cases, we do have surveillance programs in place for diseases that we that we know are of concern for us.”

She adds, “Our trade partners are very interested in what controls we put in place and how we eradicate diseases, so we share that information, and that helps to build their confidence, and allows us to trade, even sometimes in the face of an outbreak.”

Top of mind right now is Highly Pathogenic Avian Influenza (HPAI), and Sifford says that although this battle has been a long one, the USDA team can effectively follow protocols that have been laid out for other viral diseases in the past.

“Our action strategy is really made up of four key parts,” she says. “Understanding the virus in the cattle, understanding how it’s moving and what the effects are on the cattle, how it’s distributed amongst the cattle herd, and being able to address that by mitigating the movement of the virus, and then providing support to the producers to ensure business continuity.”

Ken McCarty, one of the owners of McCarty Family Farms in western Kansas identifies factors that are largely beyond their control as events they are closely watching. Events such as the Covid-19 pandemic, the ongoing war in Ukraine, and their subsequent effects on fuel and commodity markets exemplify these difficulties.

“Those sort of ‘black swan events’ that used to be once in a decade now appear to be occurring yearly or every couple of years,” McCarty explained. In response, the farm aims to price-proof their operations, ensuring they can withstand these unpredictable shifts.

HPAI was not on the 2024 radar for McCarty Farms. Nonetheless, their prior planning for foreign animal disease outbreaks allowed them to quickly adapt and take necessary actions. As they put it, “It’s those types of events that are midterm challenges that we’re always trying to prepare for.”

Sifford emphasizes that farmers are not alone in prevention or treatment for HPAI. “We do have a number of financial incentives available to help producers through all of this, from covering the testing and some of the veterinary costs, to having somebody come out and help you with a biosecurity plan or audit, personal protective equipment for employees,” she says.

“We really encourage producers to be involved in the status program, because this is an important way for us to understand where the virus is and what’s going on, and it gives producers a level of confidence that they’ve maintained the biosecurity necessary to keep from having to worry about the virus.”

USDA Invests $17.6 Million to Protect Health and Welfare of Livestock

Wed, 11 Sep 2024 15:55:31 GMT

Highly pathogenic avian influenza (HPAI) and African swine fever (ASF) are two high-priority research areas that will be funded through a $17.6-million investment by USDA’s National Institute of Food and Agriculture (NIFA) to protect the health and welfare of agricultural animals.

“Protecting the health and welfare of agricultural animals is integral to ensuring a safe, sustainable, resilient and ethically-sound food system,” NIFA Director Manjit Misra said in a release. “Healthy livestock are more productive and less likely to harbor and spread diseases that can affect humans. In addition, properly managed livestock systems help maintain biodiversity and sustainable land use.”

These projects are part of USDA’s “One Health” efforts, an integrated, collaborative approach to address issues that impact the health of people, plants, animals and our ecosystems. The awards include $12.7 million for 27 projects funded through NIFA’s Agriculture and Food Research Initiative’s (AFRI) Diseases of Agricultural Animals program and $4.8 million for 10 projects funded through AFRI’s Welfare of Agricultural Animals program.

The AFRI Diseases of Agricultural Animals program focuses on maintaining healthy agricultural animals to ensure a safe and adequate food supply, USDA explains. The program supports research in whole-animal health, including disease prevention and control.

“Several projects focus on research related to vaccines that could mitigate the spread of HPAI and ASF. HPAI is a major threat to animal health, trade and the economy worldwide. ASF is a deadly pig disease that spreads rapidly and affects domestic and wild swine. While not a threat to human health, the virus could devastate America’s swine industry and food supply if it entered the United States,” USDA says.

Examples of the 27 funded projects include:

• University of Georgia researchers aim to develop mass vaccination strategies against a prevalent HPAI subtype. The potential benefits extend beyond avian influenza, paving the way for similar studies on other respiratory viruses affecting poultry and livestock.

• Massachusetts Institute of Technology scientists will design and evaluate ASF engineered vaccine antigens. This work will ultimately lead to development of a vaccine against ASF to aid in disease control and swine health.

• University of Missouri researchers plan to develop safer and more effective swine influenza vaccines, with the potential to reduce both animal and human influenza infections, and block potential zoonotic transmission from swine to humans.

The AFRI Welfare of Agricultural Animals program supports projects that evaluate current animal agriculture production practices and/or development of new or enhanced management approaches that safeguard animal welfare and adaption to climate change, the release says.

• Purdue University researchers will investigate the most effective indicator traits and breeding strategies to enhance heat tolerance in ducks. Scientists plan to develop guidelines that outline optimal management and breeding strategies to improve heat tolerance in poultry—offering a potential long-term solution to climate change impacts on poultry production globally.

• University of Vermont scientists will investigate how early-life calf management affects long-term behavioral development, emotional states and physiological stress in dairy cattle. The results will benefit the dairy cattle industry by increasing longevity and improving animal welfare and care standards.

Ground Beef Tests Negative for H5N1, says USDA-APHIS

Thu, 02 May 2024 15:46:16 GMT

The USDA Food Safety and Inspection Service (FSIS) announced results from testing 30 samples of ground beef on Thursday, showing that all were negative for H5N1.

The agency made the announcement on its website, available for review here .

USDA-FSIS said it collected the samples from “states with dairy cattle herds that had tested positive for the H5N1 influenza virus at the time of sample collection. The samples were sent to APHIS’ National Veterinary Services Laboratories (NVSL) for PCR testing.”

PCR stands for polymerase chain reaction. Such testing is done to identify the presence or absence of human pathogens in food. Common pathogens routinely tested for in food include E. coli and Salmonella, for instance. In the ground beef study, no virus particles were found to be present.

The USDA said it is working on two additional beef safety studies. According to the information posted online, these include:

1. Beef muscle sampling of cull dairy cows condemned at select FSIS-inspected slaughter facilities: FSIS is currently collecting muscle samples at FSIS-inspected slaughter facilities of cull dairy cattle that have been condemned for systemic pathologies. The samples will be analyzed by APHIS using PCR to determine presence of viral particles. The results are forthcoming and will be posted as soon as they become available.

2. Ground beef cooking study: ARS will be conducting a beef cooking study and will be using a virus surrogate in ground beef and cooking it at different temperatures to determine log-reduction of the virus. The results will be posted as soon as they become available.

The agency said the results from both studies will be posted as soon as they become available.

A Message to the Ag Industry about H5N1

Fri, 26 Apr 2024 20:49:16 GMT

“We’re going on a bear hunt. We’re going to catch a big one… We’re not scared.”

So goes a beloved children’s book written by Michael Rosen. The story is a metaphor for how to address fear. Kay Russo, DVM, often reads it to her son and daughter, ages 4 and 6.

“This unfortunate family seems to deal with a lot of issues as they’re going on their hike,” Russo says. “Ultimately, every time they reach one of these issues, the book basically says, ‘You know, we can’t go over it. We can’t go around it. We can’t go under it. We have to go through it.’”

That story illustrates how the dairy industry must deal with the growing impact of H5N1, says Russo, Novonesis technical services manager for dairy and poultry. She’s watched the spread of the virus with alarm and urges U.S. leaders across dairy and agriculture to step up and take action.

“Address it head-on,” she says. “Don’t hide.”

As with all major threats, she says ag needs a comprehensive, cohesive plan to address the virus in dairy – and to also look at how to protect the beef, pork and poultry industries.

“At this point, I believe it’s important to take one day at a time and systematically answer the questions that we need to get answered in order to define a sustainable path forward,” Russo says.

“We have a very clear picture that it’s in the udder and is being shed in milk. But where else do we need to be concerned? That matters because that is going to define the control tactics to reduce spreading it from cow to cow. Those questions are ultimately going to be the pillar of our understanding and help to define strategies for controlling the virus in a sustainable way.”

On The Front Line
Help can’t come soon enough for dairy producers and veterinarians in the trenches working with cows.

Veterinarians such as Dr. Barb Petersen in Texas have been dealing with the virus in their clients’ dairy herds since at least March.

“It has been circulating here as early as February, based on retrospective feedback from owners and fellow veterinarians,” says Petersen, owner of Sunrise Veterinary Service in Amarillo.

By early March, she had begun sending daily emails and text messages to her Texas Panhandle dairy clients who needed answers and support.

Petersen, who has been in practice 15 years, did her best to provide both. But she didn’t know what she was dealing with. Neither did any other veterinarian Petersen reached out to within 200 miles of her practice.

“We started to text and email each other, and give summaries of ‘OK, here’s the test that this doctor has run. Here’s what another colleague has run,’” Petersen recalls.

“We tested for every single viral bacterial mycotoxin, lepto, rumensin toxicity, nitrates… I mean, you name it, every single thing that we vaccinate for, we tested for, for sure, right off the bat. And then even some of the things that we don’t or can’t vaccinate for. We tried to cast a really wide net.”

None of the initial tests, conducted by the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL), provided an answer.

Recurring Symptoms Emerge

Some members of the animal health community suspected winter dysentery – an acute, highly contagious gastrointestinal disorder that can affect housed dairy cattle of all ages.

Petersen was skeptical.

“The first clinical symptom I saw was cows that had indigestion. They had manure that wasn’t well-digested, manure with particles of feed in it,” she says.

As she checked more cows and talked with colleagues, more information came to light and she began to identify recurring symptoms: thick, colostrum-like milk; lesions on cow vulvas; high temperatures; respiratory distress; a drop in feed consumption; and a corresponding lack of rumination. None of it added up to winter dysentery.

“This is a really strong and fierce reminder to keep your hands on the cows,” Petersen says. “It’s wonderful to have data, but you have to trust and then verify.”

When Russo at Novonesis got news of the problem from a colleague, she called Petersen.

Russo has worked as a dairy veterinarian and is also a board-certified poultry veterinarian. She and Petersen discussed what kinds of tests had already been done and what health concerns had been ruled out.

“I said, ‘You know, I may sound like a crazy person, a tinfoil-hat-wearing person, but this sounds a bit like (highly pathogenic avian) influenza to me. We’ve seen this particular strain of influenza that’s been circulating, that’s been jumping into mammalian hosts,’ and I kind of left it there,” Russo recalls.

More conversations between Russo, Petersen and other veterinarians ensued. Russo encouraged Petersen to collect some of the dead birds she had encountered at the dairies and submit them to TVMDL for testing, which she did.

On March 19, Petersen received a call from the Texas lab, confirming the wild birds were positive for H5N1.

At about the same time, barn cats at the dairies Petersen worked with were getting sick and starting to die. They had consumed some of the H5N1-infected birds and milk that had not been pasteurized.

“I spent one weekend picking up dead birds and the next weekend picking up dead cats. It was very sad,” Petersen says.

Science Provides Answers
Petersen sent some of the dead cats and a pooled sample of milk to TVMDL pathologists for testing. Because of their heavy workload, she sent the same material to a former veterinary classmate at Iowa State University (ISU), Dr. Drew Magstadt, now a pathologist at the school’s diagnostic laboratory.

“Whenever I’ve gotten into a real jam professionally – like, you have a question that you can’t seem to find an answer to – the group of folks that have always helped me solve it have been pathologists,” Petersen says. “It’s been pathologists that I could give the clues to who helped finish the puzzle.”

On a warm March night in Amarillo, Petersen sat resting on her back porch at home when a text message from Magstadt popped up on her phone.

“There’s something in the results,” he wrote. “Can I call you?”

On the phone, Magstadt shared what he’d found in the lab tests done on the cats and milk: H5N1.

“I was like, ‘Are you serious?’” Petersen asked Magstadt. “Are you going to run those tests again?”

“Yes,” he said. “Just to make sure.”

The initial H5N1 confirmation flabbergasted Magstadt. The next day, he retested the samples to confirm the finding.

“I had thought we would find the results were negative and we would move on to other testing. So I was very, very surprised when the results came back positive,” says Magstadt, ISU clinical associate professor and a pathologist at the Iowa State Veterinary Diagnostic Laboratory.

The National Veterinary Services Laboratory (NVSL) then confirmed Magstadt’s findings. The documentation of H5N1 by NVSL in a sample of milk from a dairy cow represented an industry first.

“The most surprising part of this, in my mind, is the fact that we’re finding so much virus as we are in the milk, in the mammary gland,” Magstadt says.

‘Show Us The Data’
On April 23, the U.S. Food and Drug Administration (FDA) reported it had detected “viral particles of H5N1 avian influenza” in pasteurized milk available for purchase at grocery stores.

Russo is quick to point out this doesn’t mean the actual virus is in milk. Rather, it’s the genetic material known as RNA.

“I think the FDA needs to show us the data,” Russo says. “The fact that there is viral material in some of the milk on shelves, as detected by rt-PCR. That test doesn’t say whether it is alive or dead. Virus isolation is necessary. The first tests have not grown virus, thankfully, but we need more data.”

No unusual human illnesses have been documented. Government health officials say they have seen nothing unusual in flu activity, according to a senior official at the Centers for Disease Control and Prevention (CDC) who was interviewed for this story. The overall assessment and risk to human health remains low from H5N1, the official says.

“CDC looks for a host of flu-like symptoms,” he told “U.S. Farm Report” host Tyne Morgan during a phone interview. “They do so by looking at people coming into emergency rooms, care systems, etc.”

Yet anecdotal evidence suggests the people most likely to be infected – dairy farm workers who have their hands on cows regularly – aren’t necessarily going to doctors for treatment.

The World Health Organization (WHO) website references just one “laboratory-confirmed case of human infection with an influenza A (H5N1) virus on 1 April 2024” on a dairy farm.

“It’s a mild, mild case and the only symptom he had was pinkeye,” Sid Miller, state commissioner of the Texas Department of Agriculture, told “AgriTalk” host Chip Flory at the time, as reported on AgWeb.

That Texas case marked the second confirmed human case of influenza A(H5N1) detected in the U.S. — and the first in the dairy industry. The first documented case, identified in 2022, involved a person in Colorado who worked with infected poultry that tested positive for the virus.

During his interview with Miller, Flory asked whether the virus could impact beef cattle at some point.

“You’ve seen what’s happened in the cattle markets,” Flory said. “They’re looking at it like this is a major problem for beef.”

Problems aren’t anticipated for Texas beef cattle, which consist primarily of feedlot cattle in the Panhandle, Miller replied.

“The cattle that get it are the older lactating cows, and we don’t have those in the feedlot,” Miller explained. “I think we’re OK, but we’re certainly going to research that.”

Tip Of The Iceberg?
So far, H5N1 has been officially confirmed in only 32 herds in eight states, according to data from USDA’s Animal and Plant Health Inspection Service (APHIS).

Some veterinarians working with dairies in Texas believe the virus is more active than current data suggest. Nick Schneider, a consulting dairy practitioner, is one of them.

“The thing is, when you get into the Panhandle of Texas, I’m not sure there’s anybody (dairy farms) that did not have it,” says Schneider.

Texas is home to 335 Grade A dairies with an estimated 625,00 cows, according to information on the Texas Association of Dairymen website. More than 100 of those operations are in the Panhandle.

The virus likely is being under-reported by the dairy industry because the presence of the virus in dairy cows is new, and there are no reporting requirements, Russo says.

“It’s not a foreign animal disease like it’s considered in poultry, where there are reporting requirements,” she explains. “This is considered an emerging disease (in dairy cattle).”

The dairy industry needs to be “very forward looking” now and address the virus, advises Schneider, the Texas dairy consultant.

“Looking at what happened in the rearview mirror is great, but if you’re not looking at where you’re going, it’s really just a pointless endeavor,” he says.

To that end, he advises gaining insights and expertise in preparation for whatever new information emerges next.

“We need to think about this potentially being something we have to live with, as being a part of the industry in the future,” Schneider says. “I hope I’m wrong. I would love to be wrong about that. But it’s something that we definitely need to consider when we’re thinking of how we’re going to manage it.”

Lessons From Swine And Poultry
Russo also advocates learning the lessons from swine and poultry, which have faced a variety of viral challenges for years.

“It’s important that we don’t try to reinvent the wheel as the cattle industry, but sort of cross the aisle to interact with the poultry folks and the swine folks who have gone through this repeatedly over the years and learn from the defined principles they use and try to adapt them into the bovine space,” she says.

Both swine and poultry have modified their animal management practices from the farm to the marketplace as a result of those experiences.

“Poultry, for instance has very distinct biosecurity principles they abide by to include lines of separation,” Russo says. “One is they keep the outside world out. Another is their use of PPE (physical protective equipment) to protect employees and also the birds from anything that might be carried onto the farm.”

The latter is a message Dr. Barb Petersen has taken to heart. Petersen says she was exposed to H5N1 for more than a month before she learned about the virus and its ability to infect dairy cows and people.

“I’m very fortunate that I never got sick,” she says.

Her advice? “Protect yourselves and your people on the dairy. There’s been underreporting of the virus. Understandably, there’s been a lot of fear. But every dairy that I’ve worked with has – with the exception of one – had sick human beings at the same time they had sick cows.”

Based on that knowledge, Petersen has acquired PPE available through Texas Health and Human Services.

“All the states have personal protective equipment available. Go and get it for your dairies,” she encourages other veterinarians. “If a dairy is on the fence, just provide it to them, offer it to everybody.”

Petersen says she has worked with people infected by H5N1 who do not interact with dairy cows. “I’m talking owners and feeders who don’t usually touch cows,” she says.

Research is underway to determine how much of a health risk the virus poses to humans, Russo says.

“This is a rapidly evolving situation, and the people that are working on it are doing everything they can to ensure the safety of those individuals that are most at risk,” she says.

A Paradigm Shift
The virus continues to hit the U.S. poultry industry hard.

Cal-Maine Foods, the largest producer and distributor of fresh shell eggs in the U.S., announced April 2 that chickens at its facility in Parmer County, located in the southwest part of the Texas Panhandle, tested positive for the virus. As a result, Cal-Maine had to cull nearly 2 million chickens − 1.6 million hens and 337,000 pullets.

In the AgriTalk discussion aired earlier this spring, Flory asked Miller, the Texas ag commissioner, whether he believes state agriculture department investigators are in front of the latest issues with HPAI in dairy cattle.

“I think so,” Miller replied. “We’ve got about 10 months before the ducks and geese come back, so I think we’ll have it figured out by then.”

Moving forward, the U.S. livestock industry might operate in a new world – one where the H5N1 virus is endemic.

Russo is undaunted by the challenge.

“This is not insurmountable, but it’s an issue we need to address swiftly,” she says.

Culled dairy cows going into the food supply deserve special attention, she says.

“We need to do the work so that we can define those movement strategies for the practitioners that are being asked to write health certificates on these farms that have the virus circulating,” Russo says.

The dairy industry needs to be more proactive for the sake of the poultry industry, she adds.

“Putting our heads in the sand, and hoping it burns itself out is not going to work. It’s just not,” she says. “It would take down the entire poultry industry by doing that, because this is highly pathogenic to them.”

That is not hyperbole, Russo says: a dime-sized piece of manure with H5N1 can infect up to 1 million chickens or turkeys.

In essence, the livestock industry needs to go on a bear hunt, as the children’s story says.

‘We can’t go over it. We can’t go around it. We can’t go under it. We have to go through it.”

With that as the focus, solutions to H5N1 can be found and help delivered to livestock producers and veterinarians on the front lines and, ultimately, the U.S. agriculture industry can insure a safe food supply.

South Dakota Confirms First Case of HPAI in a Dairy Herd

Thu, 11 Apr 2024 21:41:59 GMT

The South Dakota Department of Agriculture (DANR) and the Animal Industry Board (AIB) have received confirmation from the United States Department of Agriculture’s (USDA) National Veterinary Services Laboratory (NVSL) of the detection of highly pathogenic avian influenza in a dairy cattle herd in South Dakota.

This is the first confirmed case of HPAI in a dairy operation in South Dakota.

“South Dakota Dairy Producers encourage all dairy producers to closely monitor their herd and contact their herd veterinarian immediately if cattle appear symptomatic,” said Marv Post, Chairman of South Dakota Dairy Producers, in a prepared statement. “USDA continues to emphasize that pasteurization kills the virus and that milk and dairy products are safe to consume.”

AABP Decides to Reference Cattle Disease as Bovine Influenza A Virus (BIAV)

Thu, 26 Sep 2024 18:58:48 GMT

On Sunday evening, the American Association of Bovine Practitioners (AABP), released a letter to its media partners to update them on how the organization will reference the emerging cattle disease, currently confirmed in dairy herds in six states, moving forward.

“Because this infection in cattle is not the same as highly pathogenic avian influenza (HPAI), after thoughtful consideration and discussion with many experts, the AABP will now refer to this as Bovine Influenza A Virus (BIAV), which more accurately depicts it,” wrote Geni Wren, director of marketing and communications for the organization, in an email accompanying the letter.

The letter was developed and signed by AABP executive director, Fred Gingrich, DVM, and president Michael Capel, DVM.

Gingrich and Capel are asking other organizations, state animal health officials, diagnostic labs, and state and federal agencies to use Bovine Influenza A Virus (BIAV) “so we can be consistent with our messaging and better distinguish the disease syndrome in cattle from the pathogenesis in birds. We believe it is important for the public to understand the difference to maintain confidence in the safety and accessibility of beef and dairy products for consumers,” they wrote.

The letter is available in its entirety for review here:

HPAI Now Detected on Ohio Dairy: Strange Bird Flu Concerns See Growth

Thu, 26 Sep 2024 19:03:22 GMT

Ohio has become the sixth state where dairy cattle have tested positive for highly pathogenic avian influenza (HPAI), also known as bird flu. A recent news release from the Ohio Department of Agriculture (ODA) reports presumptive positive results from dairy cows in Wood County.

According to officials, the cows arrived in Wood County on March 8 from a dairy in Texas. That dairy later reported a confirmed case of HPAI. The Ohio dairy operation alerted state officials when the livestock began showing signs of illness. State officials are awaiting confirmation from the U.S. Department of Agriculture.

“We have official confirmation that we do have a case at a dairy in Wood County of HPAI, which is an influenza,” says ODA Director Brian Baldridge. “We’ve been working with this in the poultry industry for about the last two-and-a-half years and it has found its way into the dairy industry. We are working diligently with the dairy, with their vets and with our Animal Health division and our state veterinarian, Dr. (Dennis) Summers, on this issue.

According to the USDA, HPAI has now been detected in five other states, including:

Texas
Kansas
New Mexico,
Idaho
Michigan

“Clinically sick dairy cattle from affected herds range from 1% to 20%, with an average of 10% of the milking herd affected. There are no confirmed reports of death loss in dairy cattle directly attributed to these detections. Most sick cows begin recovering within a few days.”

“Federal and state agencies continue to conduct additional testing from sick animals and in unpasteurized clinical milk samples from sick animals, as well as viral genome sequencing, to assess whether HPAI or another unrelated illness may be underlying any symptoms,” the ODA reports.

The agency notes that clinically sick dairy cattle from affected herds range from 1% to 20%, with an average of 10% of the milking herd affected. Currently, there are no confirmed reports of death loss in dairy cattle directly attributed to these detections with most sick cows recovering within a few days.

HPAI symptoms in dairy cattle include:

Sudden drop in milk production.
Some severely impacted cows are producing thicker, more concentrated, colostrum-like milk.
Drop in feed consumption with a simultaneous drop in rumen function, accompanied by loose feces and some fever.
Impacted herds have reported older cows in mid-lactation may be more likely to be severely impacted than younger cows, fresh cows or heifers.
Some herds have reported pneumonia and mastitis.

Officials are strongly advising dairy producers to use all standard biosecurity measures. They note it’s important for producers to clean and disinfect all livestock watering devices and isolate drinking water where it might be contaminated by waterfowl. Farmers are also being asked to notify their herd veterinarian if they suspect any cattle within their herd are displaying symptoms of this condition.

USDA Proposes Amendments to APHIS's Traceability Regulations

Thu, 19 Jan 2023 20:04:19 GMT

USDA published a proposed rule which would amend U.S. animal disease traceability regulations to require eartags in cattle and bison that are both visually and electronically readable — electronic identification (EID) tags.

Some changes have been made to a prior APHIS plan, including now the agency using the term EID tags instead of radio frequency identification (RFID) tags. APHIS said that is to accommodate the potential for future technologies other than RFID relative to the tags.

Industry Responds

Ethan Lane, vice president of government affairs at NCBA, broke down the timeline for the transition to EID tags in Thursday’s AgriTalk.

“We currently have the RFID tag rule that we saw at the end of the Trump administration that took a three or four year period to ramp up and transition to,” Lane says. “This EID tag will go live as soon as it is finalized, which is likely to be a year to 18 months.”

What’s at Stake

The EID system is aimed at helping the U.S. cattle industry deal with the emergency response to animal disease events, with APHIS concluding that while foot and mouth disease (FMD) and other diseases have been largely excluded from the U.S., “exclusion of every high impact disease through every pathway of introduction is likely an unachievable task.”

Kent Bacus, NCBA’s executive director of government affairs, echoes APHIS, saying FMD is one of his association’s biggest concerns.

“We haven’t had a case of FMD in the U.S. since the 1920s, and there hasn’t been FMD in North America since the 1950s,” he says. “We have a very naive herd that would be devastated by FMD, as would other hoofed livestock.”

Disease management tactics aside, Bacus says the domino affect FMD would have on the supply chain that is continuously being soddered and broken would be “catastrophic.” He points to highly-pathogenic avian influenza (HPAI) and African swine fever (ASF) as examples.

The Gameplan

Under the proposed rule, APHIS would require tags to be used that are both visually and electronically readable for interstate movement of cattle and bison six months after a final rule is published in the Federal Register.

Comments on the APHIS proposed rule are due Mar. 20. There is not yet a definitive date when the plan will finally be in place.

USDA Awards $14.4 Million in Farm Bill Funding to Protect Animal Health

Tue, 01 Dec 2020 19:38:43 GMT

The USDA’s Animal and Plant Health Inspection Service (APHIS) is awarding $14.4 million to 76 projects with states, universities and other partners to strengthen animal health programs.

From increasing practical livestock biosecurity measures to advancing rapid depopulation and disposal abilities during high-consequence animal disease outbreaks, the funding will support endeavors to protect animal health in the U.S. According to a USDA release, the funding will also fund projects to enhance early detection of high-consequence animal diseases and improve emergency response capabilities at National Animal Health Laboratory Network (NAHLN) veterinary diagnostic laboratories.

“We continue to use our Farm Bill funds to increase our capabilities and prepare for potential foreign animal disease incursions,” USDA Undersecretary for Marketing and Regulatory Programs Greg Ibach said in the release. “Our consultation board and leaders in animal health and laboratory diagnostics provided recommendations for the type of projects we would fund, to make sure we were targeting these funds where they can make the most impact. Our partners across states, laboratories and industry alike will benefit from the projects we are funding today.”

This is the second year of funding from the 2018 Farm Bill as part of an overall strategy to help prevent animal pests and diseases from entering the country and reduce the spread and impact of potential disease incursions. Last year, APHIS provided $10.2 million to fund 44 projects.

This year’s funding will support:

National Animal Disease Preparedness and Response Program
$9.3 million will support 46 National Animal Disease Preparedness and Response Program (NADPRP) projects that will address critical livestock biosecurity and large-scale depopulation and carcass disposal concerns in all major livestock industries across all regions of the U.S. These projects will be led by state animal health authorities in 16 states,14 land-grant universities and 2 industry/veterinary organizations.

> 24 projects will focus on livestock biosecurity
> 22 projects will focus on large-scale animal depopulation and carcass disposal in animal disease outbreak response events
> 12 of the projects are national in scope
> 7 of the projects have a regional scope
> 27 projects focus on state-specific issues
National Animal Health Laboratory Network
$5.1 million will help fund 30 National Animal Health Laboratory Network (NAHLN) projects to be led by NAHLN laboratories in 21 states. The projects will focus on early detection of high-consequence animal diseases and improve emergency response capabilities at NAHLN veterinary diagnostic laboratories. In addition, some of the projects are aimed at improving diagnostic testing for high concern diseases, including African swine fever, classical swine fever, foot-and-mouth disease and avian influenza.

7 Steps to Create a Biosecurity Plan

Fri, 13 Nov 2020 02:32:19 GMT

No matter what type of livestock operation you run, biosecurity should always be at the forefront of your mind. Putting biosecurity protocols in place can help reduce the risk of disease being transferred to not only livestock, but to humans as well.

According to Joe Armstrong, DVM, University of Minnesota Extension cattle production systems educator, having a biosecurity plan can help protect your farm from external pathogens and can minimize the transmission of diseases on your operation. To build a biosecurity plan for your farm, Armstrong provides these seven steps.

1. Determine your goal.

Before you can develop your plan, it is important to determine your end goal. You can’t get to where you are wanting to go unless you know where you are at. To do this, Armstrong suggests asking yourself two questions:

Is there a specific disease that you are looking to target that you already have?
Is there a particular disease you are worried about acquiring?

If you don’t know the answers to these questions, that’s okay. Reach out to your veterinarian for help.

2. Develop your team.

One of the most valuable members to have on your farm’s team is your veterinarian. When formulating your biosecurity plan, be sure to include them in on the discussion.

“Your veterinarian is one of the only people you work with that can comment on your entire system and how everything works together,” Armstrong says. “They have specific biosecurity training that can help you develop a plan that targets your most significant transmission risks.”

3. Formulate the plan.

As you begin to write down your farm’s intentions, it is crucial that you be as specific as possible. No matter how simple a protocol may be, you still need to have it in writing. Armstrong suggests creating visible materials that can serve as a reminder to you and your staff.

4. Get everyone on board.

“Biosecurity only works if everyone follows the protocols,” Armstrong says. “One person that isn’t on board can derail the whole thing. Make sure everyone understands what to do and make sure everyone understands why it is important.”

Consider having a team meeting to go over the new protocols and ask employees for their suggestions and feedback.

5. Start the plan.

Now that the plan has been given the green light, it’s time to put it in action.

“The sooner it is in place, the sooner you can refine the protocols and identify problem areas that need to be resolved,” Armstrong says.

6. Fine tune.

Because of workforce turnover and changing conditions on dairy farms, biosecurity training needs to on-going and continually reinforced. It may be helpful to ask your veterinarian to attend these training sessions to answer some of the questions your team members might have.

7. Evaluate and make adjustments.

One of the most important steps in formulating a biosecurity plan is to make adjustments as necessary. Be sure to record incidences of diseases to help measure whether you plan is working or not

“If your plan has been given enough time to work, you can decide if you need to change your plan based on your evaluation,” Armstrong says.
