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.

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.

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.

U.S. to Expand Bird-Flu Testing of Beef in Slaughterhouses

Fri, 16 Aug 2024 17:31:33 GMT

The U.S. Department of Agriculture said on Tuesday it will expand bird-flu testing of beef entering the food supply as part of its response to the ongoing outbreak among dairy cattle, adding that U.S. beef and dairy products remain safe to consume.

USDA officials, in a call with reporters along with staff from other U.S. health agencies, said the tests will begin in mid-September and urged livestock workers to remain vigilant.

Nearly 200 herds in 13 U.S. states have contracted bird flu since March after the virus jumped from wild birds to cows, according to USDA data.

The USDA in May tested 109 beef samples from dairy cows sent to slaughter and found bird flu virus particles in one cow’s tissue sample. Older dairy cattle are often slaughtered for ground beef.

The expanded testing will continue for the rest of the year, and will focus on beef from dairy cows, said Emilio Esteban, USDA’s under secretary for food safety.

Eric Deeble, deputy under secretary for marketing and regulatory programs, said the USDA is confident with the current level of bird-flu testing conducted by the nation’s dairy farmers.

“I do feel that the response is adequate,” he said.

The Food and Drug Administration is talking with states about the plausibility of additional nationwide raw milk testing, said Steve Grube, chief medical officer of the Center for Food Safety and Applied Nutrition.

Colorado implemented mandatory weekly milk testing for dairy farmers on July 22 and has since detected 10 additional positive herds in the state.

Farm workers remain at risk of bird-flu infections so long as the virus circulates among livestock, said Nirav Shah, principal deputy director at the Centers for Disease Control and Prevention.

Thirteen poultry and dairy workers have contracted bird flu since April, according to the CDC.

The CDC is working on expanding its surveillance wastewater testing to H5 viruses in advance of the fall and winter flu season, Shah said.

Bird Flu Outbreak Reported in Minnesota Dairy Herd, the State's First

Thu, 06 Jun 2024 21:02:39 GMT

June 6 (Reuters) - The ongoing U.S. outbreak of avian flu in dairy cattle reached Minnesota on Thursday as the state announced its first infected herd.

More than 80 dairy herds have been infected with the virus across 11 states since late March, and three dairy workers have tested positive for the virus.

The Minnesota Board of Animal Health said the farmer of the affected herd reported more than 40 cows with signs of fever. The animals were tested on Monday and the U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratories confirmed the positive test on Wednesday night.

The animals are recovering, said Brian Hoefs, the state veterinarian.

Milk from the sick cows was disposed of, and the state Board of Animal Health has quarantined the entire herd for 30 days to reduce the risk of the virus spreading off the farm, the agency said. After 30 days from the last positive test result, the herd can be retested to be released from quarantine, the agency added.

“We knew it was only a matter of time before this detection would reach our doorstep,” said Hoefs. “It’s important for dairy farmers to follow the example of this herd and test sick cows.”

This was not the first Minnesota dairy farm tested for avian flu due to cattle showing signs of illness, but it was the first to confirm positive results, Hoefs said.

More samples from dairy farms could be sent to the state lab in the coming days, he said.

“Once this news gets out, then it kind of triggers other farms to consider doing the testing if they were on the fence prior,” Hoefs said. “My guess is we will see more testing later this week into next week.”

The other states that have reported infected herds so far are Colorado, Idaho, Iowa, Kansas, Michigan, New Mexico, North Carolina, Ohio, South Dakota and Texas.

Dairy cows with avian flu have died or been slaughtered by farmers after not recovering, Reuters reporting found. The USDA said that the vast majority of cows recover from the illness.

APHIS To Require Electronic Animal ID for Certain Cattle and Bison

Thu, 26 Sep 2024 18:29:58 GMT

USDA’s Animal and Plant Health Inspection Service (APHIS) has taken another step toward limiting the impact of an outbreak of foreign animal diseases by amending and strengthening its animal disease traceability regulations for certain cattle and bison. By requiring electronic animal identification for certain cattle and bison, APHIS put into place the technology, tools and processes to help industry stakeholders quickly pinpoint and respond to a foreign animal disease outbreak.

“Rapid traceability in a disease outbreak will not only limit how long farms are quarantined, keep more animals from getting sick, and help ranchers and farmers get back to selling their products more quickly – but will help keep our markets open,” said Dr. Michael Watson, APHIS administrator.

APHIS said one to the rule’s most significant benefits for farmers and ranchers will be the enhanced ability of the United States to limit impacts of animal disease outbreaks to certain regions, which the agency called a “key to maintaining our foreign markets. By being able to readily prove disease-free status in non-affected regions of the United States, we will be able to request foreign trading partners recognize disease-free regions or zones instead of cutting off trade for the entire country. Traceability of animals is necessary to establish these disease-free zones and facilitate reestablishment of foreign and domestic market access with minimum delay in the wake of an animal disease event.”

The April announcement enhances a rule finalized in 2013 for the official identification of livestock and documentation for certain interstate movements of livestock.

The final rule applies to all sexually intact cattle and bison 18 months of age or older, all dairy cattle, cattle and bison of any age used for rodeo or recreation events, and cattle or bison of any age used for shows or exhibitions.

The rule requires official eartags to be visually and electronically readable for official use for interstate movement of certain cattle and bison, and revises and clarifies certain record requirements related to cattle.

“USDA’s final traceability rule updates the existing requirement for animal identification that has been in place since 2013, switching from solely visual tags to tags that are both electronically and visually readable for certain classes of cattle moving interstate,” said National Cattlemen’s Beef Association president Mark Eisele, a Wyoming rancher.

“Many producers are already familiar with using these visual tags and under the new rule, they will instead use electronic tags. NCBA has worked hard to secure $15 million in funding for producers to reduce the cost of implementing this change. We also remain committed to safeguarding producers’ private data and continuing to reduce the cost of ear tags for farmers and ranchers. Our industry faces a tremendous threat from the risk of a future foreign animal disease on American soil. To avoid devastating financial losses during a potential outbreak and to help producers quickly return to commerce, we need an efficient animal disease traceability system.”

USDA said it is committed to implementing a modern animal disease traceability system that tracks animals from birth to slaughter using affordable technology that allows for quick tracing of sick and exposed animals to stop disease spread. USDA will continue to provide tags to producers free of charge to jumpstart efforts to enable the fastest possible response to a foreign animal disease.

To obtain electronic ID tags at no cost, APHIS directs producers to contact their State Veterinarian.

A copy of this rule may be viewed at the APHIS website, and the rule will be published in the Federal Register in the coming weeks. This rule will be effective 180 days after publication in the Federal Register.

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.

This story will be updated by Bovine Veterinarian and Farm Journal editorial staff as more information is available.

NEW: USDA Confirms Cow-to-Cow Transmission a Factor in Avian Flu Spread

Fri, 19 Apr 2024 21:18:17 GMT

The U.S. Department of Agriculture said this week that cow-to-cow transmission is a factor in the spread of avian flu in dairy herds, but it still does not know exactly how the virus is being moved around.

Farmers and veterinarians have been waiting for confirmation on how the virus is transmitted to better control its spread. Dairy herds in eight states tested positive over the past month, along with one dairy worker in Texas.

“Those of us that have worked with influenza for a long time were fairly quickly saying, ‘Yep it moves cow to cow,’” Jim Lowe, an associate dean at the University of Illinois College of Veterinary Medicine, said on Friday. “You can’t explain the epidemiology any other way.”

Wild migratory birds are believed to be the original source of the virus. But the USDA said its investigation into cow infections “includes some cases where the virus spread was associated with cattle movements between herds.” There is also evidence the virus spread from dairy cattle premises “back into nearby poultry premises through an unknown route,” the department said.

The USDA said cows shed the virus in milk at high concentrations, so anything that comes in contact with unpasteurized milk may spread the disease. Respiratory transmission is not considered a primary way for the virus to spread in cattle, the department added.

Despite uncertainty over transmission, USDA has not imposed quarantines to restrict the movement of cattle around infected dairies, as it does with chickens and turkeys around infected poultry farms. Infected cattle appear to recover, while bird flu is usually lethal for poultry.

The USDA said it expects that minimizing cattle movement and testing those that must be shipped, along with safety and cleaning practices on farms, should avoid the need for regulatory restrictions.

Officials reported last month that bird flu primarily affected older cows, though additional data now indicates younger cattle have been affected, the USDA said.

South Dakota Confirms First Case of HPAI in a Dairy Herd

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:

Six Questions One Industry Veterinarian Says She Is Asked Most Often About HPAI

Thu, 26 Sep 2024 19:00:28 GMT

The emerging issue of Highly Pathogenic H5N1 Avian Influenza (HPAI) in the U.S. dairy industry changes on nearly a daily basis.

Novonesis (a merger of Chr. Hansen and Novozymes) hosted a webinar on the issue on Friday to update producers, veterinarians and other members of the agricultural community.

“It’s a rapidly evolving situation,” lead presenter, Kay Russo, DVM, Novonesis technical services manager for dairy and poultry, North America, stressed at the beginning of the program.

“I’m getting a lot of questions, and I’m sure everybody on this call has questions. Or if you’re a veterinarian, you’re receiving them,” she said. “Again, this is a rapidly evolving situation, and what may seem correct today may be different tomorrow.”

Here are the six questions Russo said she is most frequently asked, and what her answers to them are – for now. Russo’s answers have been lightly edited for clarity.

Question #1: Is HNAI spreading from cow to cow?

Answer: Initially the thought was that every one of these animals was exposed to the disease from a bird. But at this point, there is some consideration for the fact that this may be spreading laterally. How it’s spreading is still unclear. There is some postulation that the virus is being spread in the milking parlor. Could it potentially be a mechanical spread from cow to cow on the milkers’ hands, or perhaps (on) the milking machines? Is it possible in these parlors where the humidity is high, it’s a warm environment that we’re seeing some aerosolization of the virus, so I would say that’s possible too. But there’s more work that needs to be done. But for all intents and purposes at this time, I would suspect there is some lateral transmission.

Question #2: Why are calves, younger lactation cows and the feedlot cattle not getting sick?

Answer: Ultimately, I don’t know the answer to this. More work needs to be done. The question needs to be answered. Are they truly not getting infected with a virus? Are they resistant to it, perhaps? Or is it that they are getting infected and just not demonstrating the clinical signs? We milk a lot of these dairy cows three times a day, so there’s a lot of eyes on them. In some of these instances, with the calves or in the feedlot cattle, you’re not handling them as often. We need to rely on the science to answer these questions in order to provide guidelines. I keep saying this, and I will continue to say it, we do not know what we do not measure. And we cannot provide guidelines around what we do not know.

Question #3: Is this a risk to humans?

Answer: The short answer is that it can infect humans. I know that in New Mexico, they are offering free testing to individuals that are working regularly with these infected herds. And if they are symptomatic – we’re seeing conjunctivitis and high fevers in some of them –they are being distributed Tamiflu for their use and for their families. 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.

Question #4: Is milk safe?

Answer: The FDA has stated the pasteurization process should kill the virus, and we should not see it in any saleable milk.

Question #5: Will this be a market limiting disease outbreak?

Answer: This is the major concern here, folks. These are important markets for us in this country. At this point, this is something that is absolutely a consideration. The goal here is to keep the farms in business.

Question #6: Are dairy farms a risk to poultry operations?

Answer: We’ve seen two commercial layer operations, one in West Texas and one in Michigan, be positive for highly pathogenic avian influenza this week. I know that there’s considerable amounts of work behind the scenes to determine the origin of the virus that caused the outbreak in those situations. Ultimately, in this circumstance, it’s going to be important that the cattle folks and the poultry folks come to the same table and talk and manage through this. We want to be good neighbors. These are two major industries in our country, so it’s important that the dialogue is there and continues so that we can keep (everyone) safe.

Twelve Cases of HPAI in Dairy Cattle Confirmed in Five States

Wed, 03 Apr 2024 18:54:11 GMT

To date, 12 cases of highly pathogenic avian influenza (HPAI) have been confirmed in dairy cattle in five states.

The U.S. Department of Agriculture has made the confirmations in dairy herds in four states: Texas (7), Kansas (2), Michigan (1), and New Mexico (1).

In addition, the Idaho State Department of Agriculture announced March 28 that it had identified its first cases of HPAI in a Cassia County dairy cattle operation. The affected facility had recently imported cattle from another state and herd that had HPAI.

Fred Gingrich, DVM and executive director for the American Association of Bovine Practitioners (AABP), says the virus identified in affected dairy cows is the same virus that has affected the U.S. poultry industry since 2022.

“The assumption is the initial herds were affected by wild migratory birds,” Gingrich told Chip Flory, host of AgriTalk, on Tuesday.

Gingrich adds that government agencies, veterinarians and livestock industry groups have more questions than answers at this point about how HPAI is infecting herds, and they are not ruling out cow-to-cow transmission.

“Clinically, it looks like that’s what is happening. Some of the newly infected herds outside of Texas had purchased animals from areas there that had affected herds. That indicates that we probably have some cow-to cow transmission,” Gingrich says. “What’s not known is how does that transmission occur? Does it occur through oral secretions, through the manure, urine, or aerosolized in respiratory secretions like it is in birds? Or is there some mechanical transfer when cows are in the parlor together?”

Adopt Good Biosecurity Practices
The many unknowns at this point make the need for producers to adopt good biosecurity measures more important than ever. Gingrich says the AABP and the National Milk Producers Federation have teamed up to release a set of biosecurity guidelines for producer and veterinarian use. The guidelines and recommendations are available at bit.ly/3TGYMul.

The key points in the guidelines, Gingrich says, encourage dairy producers to minimize any opportunity for the transmission of HPAI by: minimizing livestock contact with wild, migratory birds, isolating new animals on the farm, limiting any visits to your farm to only essential workers and practicing good, general biosecurity measures.

“If you’re moving either your own cattle home from a heifer grower, or you’re purchasing animals, talk to your veterinarian about any potential screening that you might want to do for those cattle, which is just a good practice for any potential disease,” Gingrich advises. “Certainly, you just need to be careful about herd purchases when we have unknowns with an emerging viral event.”

Producers should use the same general precautions, Gingrich adds, for beef cattle and other livestock as well.

“Currently, there are no reports of HPAI in the U.S. beef herd, but certainly producers and veterinarians should be on alert to monitor and watch for any symptoms,” he says.

Five states, Delaware, Idaho, Nebraska, Tennessee and Utah, are taking additional precautions to increase their biosecurity measures. Dairy Herd Management’s Taylor Leach reports the Nebraska Department of Agriculture (NDA) has issued a restriction on the importation of dairy cattle because of the recent HPAI outbreaks.

Silver Linings In The Clouds
When dairy cows are affected by HPAI, they tend to be only a small percentage of the total herd.

“It only affects about 10% of the cows in a herd, and it does not cause mortality, and we’re thankful for that,” Gingrich says.

Furthermore, any risk to the U.S. public from consuming dairy and meat is very low, because pasteurization destroys the virus.

Looking Ahead
Moving forward in the days and weeks ahead, Gingrich recommends that producers work closely with their herd veterinarians and sign up for HPAI alerts as they are released by the Centers for Disease Control, USDA and other federal and state agencies.

“I think the first thing is to be on the lookout for the disease symptoms in your herd; don’t hide it. We all need to work together to continue the investigation. If you have a sudden drop in appetite and milk production in your herd, the first person you should call is your veterinarian and work through to get a diagnosis, whatever that might be,” he says.

“Secondly, we want dairy farmers to know that the veterinary community cares about you. And we certainly understand that this is a scary time. So make sure that you’re relying on your veterinarian and USDA and organizations like AABP for reliable information,” he adds.

Gingrich offers counsel for veterinarians as well. “Be aggressive with diagnostics, as the investigation is ongoing. Make sure that you are working with your diagnostic labs and state animal health officials to collect the appropriate diagnostics that we have posted on the AABP website. If you’re an AABP member, we have a reporting portal where you can identify the herds with this syndrome.”

Rare Human Case of Bird Flu Confirmed. Officials Believe it Began on Texas Dairy

APHIS Now Thinks Wild Birds Are to Blame for Highly Pathogenic Avian Influenza’s Arrival on Four U.S. Dairies

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.
