Highly pathogenic avian influenza (HPAI) has been detected in another upland gamebird operation in South Dakota.

The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported that on October 11, a flock of 200 birds in a commercial upland gamebird operation in Gregory County were affected by HPAI.

The Gregory County case came just five days after another commercial upland gamebird operation in Brule County was hit by HPAI. Gregory County is directly south of Brule County and borders Nebraska.

In total, South Dakota has had three gamebird operations affected by HPAI in 2022, with the first of those being confirmed on April 13 in Deuel County.

Nearly 1.8 million birds in South Dakota have been affected by HPAI so far this year, with the exception of the three gamebird operations and one commercial layer operation in Kingsbury County, all other affected commercial flocks in South Dakota have involved turkeys.
