A commercial breeder operation in South Dakota and a commercial turkey flock in Utah are the most recently reported 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), both cases were confirmed on October 19.

The South Dakota case, located  in Roberts County, was only identified by APHIS as a “commercial breeder operation” and didn’t include the species of the 3,800 birds that were affected.

This is the first confirmed case of HPAI in Roberts County for 2022.

Meanwhile, the Sanpete County case is the county’s 17th for the year,  and six of those cases were confirmed in October. In the most recent case, 9,200 turkeys were affected. To date, all of Utah’s HPAI cases, with the exception of a commercial layer operation in Cache County, have been in Sanpete County.

Three new avian flu cases in Canada

Three new cases of HPAI were confirmed in Canada, two of which are in the same municipality in Quebec.

The Canadian Food Inspection Agency (CFIA) reported that the presence of HPAI was confirmed on October 18 in two commercial poultry flocks in La Haute-Yamaska, Quebec. Prior to this, the virus had not been confirmed in any poultry in this municipality.

Meanwhile, one day later, HPAI was confirmed in a commercial poultry flock in Hoodoo, Saskatchewan. This is also the first HPAI case in this rural municipality.


Further details concerning flock type or size have not yet been released.

So far in 2022, Quebec has had 12 cases of HPAI in commercial poultry, while Saskatchewan has had 14.
