Highly pathogenic avian influenza (HPAI) was detected U.S. commercial poultry operations in three states on December 27.
According to the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), the affected flocks were in Muskegon County, Michigan; Todd County, Minnesota; and Hardin County, Ohio.
Of the three, the Ohio case had the most birds involved. Affected was a flock of 1,363,900 commercial table egg layer pullets. This makes Ohio’s sixth commercial operation to be struck by HPAI in 2023. No state has lost more birds to HPAI than Ohio during 2023. That total has now reached 5,934,600 birds, representing the egg and turkey industries.
The Michigan case involved 31,000 commercial meat turkeys. This is the second commercial flock in the state to be infected during 2023, with the year’s other case involving 47,900 meat turkeys.
The Minnesota case involved 78,800 commercial turkey breeder hens. Minnesota has now had 34 commercial flocks affected by HPAI in 2023. The state had 81 commercial flocks struck by HPAI in 2022, making it the state with the most flocks affected during the past two years.
