Highly pathogenic avian influenza (HPAI) has been confirmed in one flock of commercial poultry and one backyard poultry flock in Quebec.

This marks Quebec’s first case in commercial poultry in 2022. Previously, the only cases involved wild geese.

The Canadian Food Inspection Agency (CFIA) reported that on April 12, a H5N1 variant of HPAI was confirmed in Val-Saint-François, and the following day it was confirmed in a non-commercial poultry flock in Haut-Saint-François.

Specific information regarding the species or number of birds in these flocks was not offered.

The infected sites have been placed under quarantine. The CFIA has established movement control measures and is recommending that other farms in the area increase biosecurity.

Avian influenza in other provinces

To date, HPAI has been confirmed in every Canadian province except Manitoba, although the only cases to have confirmed cases in poultry are Quebec, Alberta, Ontario and Nova Scotia.
