The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has confirmed a case of highly pathogenic avian influenza (HPAI) H5N1 in a commercial poultry flock in Barron County. Working with the U.S. Department of Agriculture (USDA), DATCP is taking strict measures to prevent the spread of this highly contagious virus.
The affected premises have ceased poultry and product movement, and depopulation efforts are underway to ensure the virus does not reach the food system. H5N1, which has circulated among wild and domestic birds in North America since 2021, spreads via infected birds, wild bird droppings, equipment, and clothing.
DATCP emphasizes the importance of biosecurity practices, such as disinfecting equipment, limiting animal access, and quarantining new flock additions for 30 days. Poultry owners are advised to keep birds indoors whenever possible.
A control area within 10 kilometres of the infected site has been established to monitor and restrict poultry movement. DATCP’s mapping tool helps producers determine if their operations are within this zone. Livestock owners in Wisconsin must register their premises to facilitate communication during outbreaks.
To report unusual bird mortality or illness, owners can contact DATCP at (608) 224-4872 during business hours or (800) 943-0003 after hours. Updates and resources are available on the DATCP HPAI webpage.
H5N1 has also been detected in mammalian species, with a recent case in dairy cattle reported in Texas. While Wisconsin has not identified H5N1 in its dairy herds, DATCP and USDA continue to test livestock and provide resources to ensure herd and flock safety.
For the latest updates and biosecurity resources, poultry owners can visit the DATCP HPAI webpage. Protecting livestock remains a top priority during this ongoing outbreak.
