Quebec has confirmed its first case of highly pathogenic avian influenza (HPAI) in a commercial poultry flock since January, marking the end of an eight-month period without new outbreaks in the province. The Canadian Food Inspection Agency (CFIA) reported the detection of the virus on September 15 in a flock located in Brome-Missisquoi, part of Quebec’s Eastern Townships.

• The affected farm, operated by Canards du Lac Brome, specializes in duck production.
• According to the company, the outbreak is isolated, and all necessary biosecurity measures have been implemented.
• The farm has been placed under quarantine, and the birds will be humanely culled to prevent further spread of the virus.
• Disinfection procedures are underway, with personnel in hazmat suits sanitizing equipment and vehicles entering and leaving the premises.

This marks the 60th confirmed case of avian flu in Quebec poultry farms since the H5N1 strain was first detected in the province in 2022. Although only one other farm has been affected in 2025, authorities warn that the virus continues to circulate among wild bird populations. The Ministry of Agriculture, Fisheries and Food urges poultry farmers and urban bird owners to remain vigilant and monitor for symptoms such as reduced appetite, lethargy, and abnormal egg production.

• Avian influenza poses minimal risk to public health.
• The CFIA emphasizes that the virus does not spread through properly cooked poultry or eggs, and human infections are rare.
• However, individuals working closely with infected birds or contaminated environments are advised to take precautions.

The resurgence of HPAI in Quebec follows similar outbreaks in Alberta earlier this month, where multiple commercial flocks were infected. Experts attribute the renewed spread to seasonal migration patterns of wild birds, which act as reservoirs for the virus.

The CFIA continues to monitor the situation closely and has implemented control zones to contain the outbreak. Farmers are encouraged to enhance biosecurity protocols and report any unusual bird deaths or symptoms immediately.
