The presence of highly pathogenic avian influenza (HPAI) was confirmed on June 12 in a commercial meat turkey flock in Lyon County, Minnesota.
The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported that the flock involved 92,400 turkeys. This is the first case in Lyon County in more than two years. In this most recent case, a flock of 120,300 commercial meat turkeys was struck by the virus, according to APHIS.
This marks the tenth commercial poultry operation to be affected by HPAI in 2024. Other counties to have positive detections include Meeker, Morrison, Stearns and Dodge. Most of the affected flocks have involved commercial meat turkeys, but one of the Meeker County premises included 1,368,000 commercial laying hens. Also among those 10 flock infections was a flock of 6,800 commercial turkey breeder hens in Stearns County and a commercial breeder operation in Dodge County, involving 14,100 head of poultry, but the species was not disclosed.
All cases have been of the H5N1 serotype.
This detection follows Minnesota’s first H5N1 infection of dairy cattle. Last week, it was reported that the virus had been detected in a Benton County herd. The only cases of H5N1 in poultry to be previously confirmed in Benton County were in backyard flocks, with two affected in April 2022.
