What avian flu precautions can I take to protect my livestock? Keep your livestockbio away from open water sources that wild birds frequent, keep your coop clean, and disinfect your work boots.
How can I protect my poultry from the current outbreak of avian flu (H5N1)?
Understanding how avian flu spreads will help you defend your animals (and yourself) from the virus.
- Wild birds can carry and spread the virus to other wild birds, domestic poultry, and mammals through direct contact as well as indirect contact via contaminated open water and fecal matter. Deceased wild birds can also transmit the virus to humans, poultry, and livestock. Avoid contact with dead birds.
- Domestic poultry can spread the virus within poultry flocks and to wild birds and mammals. Poultry are highly susceptible to infection.
Cattle can spread the virus to poultry and mammals.
Humans can transmit bird flu to domestic poultry flocks. Avoid contact with dead wild or domestic birds.
Transmission between animals. H5N1 spreads easily between birds and cattle. Pigs can become infected, but so far, pig-to-pig transmission isn’t common. Similarly, humans aren’t spreading the virus to other humans. If enough humans or pigs become infected, the virus could adapt and spread more efficiently within these species. In the current outbreak, human infections are primarily linked to dairy cattle, though transmission from wild birds and poultry is also possible. People can become infected when the virus gets into a person’s eyes, nose, or mouth; when it’s inhaled through direct contact with cattle, poultry, or birds; or from indirect contact with contaminated surfaces and equipment.
How Bird Flu Reaches Your Farm
- Wild birds and water sources. Ponds and other open water sources are at higher risk of bird flu contamination, as these often contain waterfowl droppings.
- Feed and bedding contamination. Wild birds can drop infected feces into feeders, troughs, and high-traffic areas. Store feed and bedding securely to prevent exposure and virus spread.
- Exposure to infected birds. Exposure in other locations can then be tracked back with you to your farm.
- Equipment, farm tours, and visitors. The virus can hitch a ride on boots, tools, and feed bags. Often, farmers don’t immediately realize they have the active virus and spread it unknowingly.
- Rodents and other wildlife. Small animals can carry virus particles into feed storage or animal housing areas.
How to Protect Your Animals
- Make a biosecurity plan. Use resources from the American Pastured Poultry Producers Association, Defend the Flock, and the U.S. Department of Agriculture (USDA) “Highly Pathogenic Avian Influenza Biosecurity Checklist.”
- Disinfect your equipment regularly. Clean and sanitize shoes, clothing, hands, and equipment.
- Limit wild bird contact. Secure feed bins, water sources, and feeders to prevent exposure to wild birds and waterfowl.
- Restrict access to your farm. This includes farm tours, employees, and neighbors. Bird flu spreads before symptoms appear.
- Monitor flock health. Ensure birds are healthy while still allowing outdoor pasture access whenever possible.
- Know the signs and isolate. Pay attention to a sudden rise in bird deaths, respiratory issues, and watery or green diarrhea. Infected birds may appear weak, eat less, lay fewer eggs, and develop swelling around the eyes, neck, and head. Purple discoloration of wattles, combs, and legs can also occur. If you see any of these, isolate your birds, take extra sanitation precautions, and have your flock tested. However, infected birds may show no signs or exhibit symptoms shortly before death.
If You Suspect Bird Flu
Bird flu can hit even the best-run farms. The key is to act quickly to protect your flock, your farm, and other animals.
- Report suspected illness immediately: Bird flu is a notifiable disease – veterinarians must report suspected cases. Call your vet for testing as soon as you suspect bird flu. Prompt reporting is crucial for containment as well as compensation. Only live birds from an infected flock are eligible for compensation; dead birds won’t be covered. Reach out to your agricultural extension office, vet, animal-health lab, or the USDA.
- Isolate: Birds with signs of illness need to be separated and their housing sanitized.
- Testing and depopulation: Have dead birds tested. If your flock tests positive, the USDA will euthanize the rest of your flock to prevent further spread. There is compensation for euthanized birds available.
