H5N1 Avian Flu Returns Early to Minnesota Poultry Farms, Affecting Over 260,000 Birds
The H5N1 avian flu, also known as highly pathogenic avian influenza (HPAI), has re-emerged in Minnesota earlier than anticipated this fall. According to Shauna Voss, Assistant Director of the Minnesota Board of Animal Health, the disease was confirmed in a Wright County commercial flock of 29,800 birds on September 1. Since then, seven commercial flocks and three backyard flocks have tested positive, leading to the culling of over 260,000 birds. This early surge is unusual, as the disease typically appears in October. Minnesota farmers have been contending with HPAI annually since the USDA detected the ongoing outbreak in 2022. The virus is primarily spread by migratory birds traveling south from Canada, which make stops in Minnesota and interact with local poultry. HPAI is a deadly strain for poultry, capable of annihilating entire flocks within days.
