The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has identified a case of highly pathogenic avian influenza (HPAI) in a backyard poultry flock in Racine County. Birds on the premises were depopulated and will not enter the food system.
The HPAI virus has continued to circulate in both wild and domestic birds in North America since December 2021. 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.
