MADISON, Wis. (WSAW) - The Wisconsin Department of Agriculture, Trade and Consumer Protection has identified a case of highly pathogenic avian influenza in a commercial poultry flock in Burnett County. DATCP and USDA animal health officials are working together in a joint incident response.

The affected premises will not move poultry or poultry products, and birds on the property were depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system. According to the CDC, HPAI does not present an immediate public health concern for the general public. HPAI also does not pose a food safety risk; properly handling and cooking eggs and poultry to an internal temperature of 165˚F kills the virus.

The H5N1 HPAI virus has continued to circulate in both wild and domestic birds in North America since December 2021. 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.
