The first case of highly pathogenic avian influenza (HPAI) in more than two months has been confirmed in the Canadian province of Alberta.

According to information on the Canadian Food Inspection Agency (CFIA) website, the latest case was confirmed on July 28 in Stettler County.

Information concerning the type of birds involved or the size of the affected flock has not yet been disclosed to the public by the CFIA. This marks the 32nd confirmed HPAI case in the province and the 20th in an Alberta commercial poultry flock. The last time HPAI was confirmed in a commercial flock in Alberta was May 11, when it was found in Two Hills County.

The last time a backyard flock in Alberta was confirmed to have been affected by HPAI was June 2. There were two confirmed cases that day, one of which was in the Wainwright Municipality and the other was in Clear Hills County.

Prior to the Stettler County case, the last time HPAI was confirmed in a commercial poultry flock in Canada was July 22, in Saint-Gabriel-de-Valcartier, Quebec. In fact, the past four cases of HPAI in Canada were in Quebec. There were also cases of HPAI confirmed in Quebec on June 28, July 3 and July 9.

Every province has had at least one confirmed HPAI case, whether it has been in a commercial flock, backyard flock, wild birds or a combination of two or more of these. However, the only provinces to have positive HPAI detections in commercial poultry are Alberta, British Columbia, Manitoba, Nova Scotia, Ontario, Quebec and Saskatchewan.

Meanwhile, in the United States, the most recent case in a commercial poultry flock was confirmed on July 26 in Sanpete County, Utah. The three most recent cases in the U.S. all occurred in commercial turkey flocks in that county.
