The presence of highly pathogenic avian influenza was confirmed in two U.S. commercial meat turkey flocks on December 12.
The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported that the Iowa flock was in Sac County, with 45,200 birds involved. The South Dakota flock was in Kingsbury County and involved 39,500 birds.
So far in 2024, Iowa has had seven commercial flocks affected by HPAI and South Dakota has had 16.
Update on another South Dakota flock
APHIS also offered an update on a previously announced flock infection involving a commercial turkey flock in Brule County, South Dakota. That HPAI detection was confirmed on December 10 and there were 50,900 birds in that flock.
Wisconsin reports flock infection
The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) on December 12 reported that the presence of HPAI was confirmed in a commercial poultry flock in Barron County.
“DATCP and the U.S. Department of Agriculture animal health officials are working together in a joint incident response. The affected premises will not move poultry or poultry products, and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system,” the agency stated in a press release.
DATCP did not offer information concerning the flock size or the type of birds involved, and APHIS has not yet provided any information about the Barron County situation.
Wisconsin has not had a confirmed case of HPAI in commercial poultry since a flock of commercial turkeys in Washburn County was infected on January 5. That is the only other reported case of HPAI in commercial or backyard poultry in 2024.
