Three commercial turkey operations in the same South Dakota County and a commercial duck breeding operation in California are the latest locations for confirmed cases of highly pathogenic avian influenza (HPAI) in the United States.

According to the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), the presence of HPAI was confirmed at three farms in Edmunds County, South Dakota, on November 20. One involved a flock of 33,400 commercial meat turkeys, another involved a flock of 19,200 turkey breeder hens and the other involved 30,100 turkey breeder replacement hens.

With these new cases of HPAI, South Dakota has now had 80 commercial poultry or upland gamebird flocks affected by HPAI during the 2022-23 outbreak. Nineteen of those flocks were affected in 2023.

APHIS also reported a confirmed HPAI infection in a flock of 23,400 commercial duck breeders in Fresno County, California. This is the third instance of a commercial poultry farm being affected by HPAI in California in 2023. The previous two both occurred in Merced County. One involved a commercial breeding duck operation while the other involved a commercial meat turkey operation.

In 2022, California had 15 commercial flocks hit by HPAI.

New HPAI cases in Canada

The Canadian Food Inspection Agency (CFIA) reported that two more commercial poultry operations have been impacted by HPAI, with both cases being confirmed on November 20.

One was in Chilliwack, British Columbia, and the other was in Rouville, Quebec.

CFIA did not reveal the type of poultry operations that were affected, or how many birds were involved.

So far during the 2022-23 outbreak, British Columbia has had 115 commercial flocks infected, while Quebec has had 42.
