- Do not push up feed with the same equipment that is used to carry dead animals or scrape manure alleys.
- Sanitize all equipment used to treat sick animals before next use.
- Avoid contamination of feed and water sources with manure.
Vaccinate animals to increase resistance against Salmonella
There are several vaccine products available for Salmonella infection in cattle. Products vary widely in efficacy and breadth of coverage, and include whole cell bacterins, core antigen bacterins, and subunit vaccines. One type of subunit vaccine, which uses specialized proteins on the surface of the bacteria (siderophores and porins), not only protects against disease caused by multiple strains of Salmonella, but decreases fecal shedding, resulting in less bacteria excreted into the environment, and thus less exposure for cows in that herd.
Salmonella infection on the dairy is not only economically devastating to farms – it represents a public health risk for people handling the animals and their families. Control requires comprehensive management steps to decrease exposure and optimize animal resistance to infection.
