The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has identified a case of highly pathogenic avian influenza (HPAI H5N1) in a backyard poultry flock in Racine County. Birds at the site were depopulated to prevent the spread of the disease.
H5N1 HPAI viruses are highly contagious and often fatal to domestic poultry. Caused by influenza type A viruses, the disease varies in severity depending on the strain and species affected. The disease can be spread by contact with infected birds, commingling with wild birds or their droppings, equipment, or clothing worn by anyone working with the animals.
DATCP continues to urge all livestock owners to implement strong biosecurity measures to protect their flocks and herds from the disease. This includes washing hands, disinfecting equipment, restricting access to animals, and separating new additions to the flock or herd for at least 30 days. Poultry owners are asked, when possible, to keep their birds indoors.
When HPAI H5N1 is diagnosed in a backyard poultry flock, risk factors are evaluated and a 10-kilometer surveillance zone may be implemented, without movement restrictions for surrounding poultry premises. To help producers determine if their poultry are located within an active control area or surveillance zone, poultry owners are encouraged to use DATCP's mapping tool.
