Gratiot County, Michigan, has had two commercial meat turkey flocks affected by H5N1 highly pathogenic avian influenza (HPAI) in less than a week.

The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) announced that the presence of HPAI was confirmed in a flock of 26,400 turkeys on May 2. HPAI was confirmed in another commercial turkey flock in that county on April 26, with 27,700 birds in that flock.

This marks the tenth commercial poultry operation in Michigan lost during the 2022-24 HPAI outbreak. Of those seven have been confirmed in 2024. The state lost two commercial flocks in 2023 and one in 2024.

Dairy herds also hit by H5N1

The H5N1 virus has not only been present in poultry operations in Michigan, but also in commercial dairy operations in the state.

According to APHIS, between March 29 and April 17, six Michigan dairy herds have been affected by the virus. APHIS did not disclose the counties where these bovine cases were confirmed, but the Michigan Department of Agriculture and Rural Development has identified the following counties: Ottawa, Ionia, Isabella and Montcalm.
