Canada has reported its second confirmed case of highly pathogenic avian influenza (HPAI) in a commercial poultry flock for 2024.

The latest detection was confirmed in Amherstburg, Ontario, on January 30, according to information from the Canadian Food Inspection Agency (CFIA). Information concerning the type of commercial flock involved or how many birds were affected has not yet been disclosed.

This is the first commercial flock in Amherstburg to be infected by HPAI during the 2022-24 outbreak.

Prior to this, the last time HPAI was confirmed a commercial poultry flock in Canada was January 3 in Papineau County.

While those are the only two instances of HPAI in Canadian commercial poultry in 2024, there have also been two non-commercial farms affected by the virus. One of those cases was in Saskatchewan and the other in Nova Scotia, making it four provinces to each have one confirmed HPAI case so far this year. However, the Saskatchewan and Nova Scotia flocks are backyard operations, those instances of HPAI should not impact poultry trade, according to rules established by the World Organisation for Animal Health.
