The USDA Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza in four additional flocks in Minnesota and Iowa. Three of those four cases occurred in counties that had no prior avian influenza detections.

The new counties affected by avian influenza are:

1.      Brown County, Minnesota – Flock of 46,800 turkeys affected

2.      Adair County, Iowa – Flock of 974,500 chickens affected

3.      Webster County, Iowa – Chicken flock infected, number of birds pending


The fourth new case of avian influenza occurred in Renville County, Minnesota. This is the third avian influenza detection in the county. Here, the virus was confirmed in a flock of 95,300 turkeys.

The flocks at each of the four farms will be depopulated and the properties will be disinfected to help prevent the spread of avian influenza.

To date, APHIS has reported 191 avian influenza detections which have impacted more than 43 million birds. APHIS and other state agriculture and wildlife agencies have reported confirmed avian influenza cases in 20 U.S. states.
