Canadian animal health authorities have confirmed the depopulation of an ostrich flock following the detection of highly pathogenic avian influenza (HPAI). The incident underscores the ongoing challenges posed by the virus, which continues to affect both commercial and non-commercial poultry operations across the country.

• The affected flock was located in Alberta, where routine surveillance and testing identified the presence of HPAI.
• Officials from the Canadian Food Inspection Agency (CFIA) immediately implemented strict biosecurity measures to contain the outbreak.
• These measures included quarantining the premises, restricting movement of birds and related products, and initiating the humane depopulation of the infected ostriches to prevent further spread.

HPAI, commonly known as bird flu, is a viral disease that primarily affects birds but can have severe economic and ecological consequences. While ostriches are less commonly associated with avian influenza compared to chickens or turkeys, they remain susceptible to infection. The virus can spread rapidly through direct contact with infected birds, contaminated equipment, or even wild migratory species, which are often implicated in introducing the pathogen to domestic flocks.

• The CFIA has emphasized that the depopulation process was carried out in accordance with international animal welfare standards.
• Disposal of carcasses and disinfection of facilities are ongoing, and surveillance in surrounding areas has been intensified.
• Authorities are also working closely with producers to reinforce biosecurity protocols, including limiting access to farms, disinfecting vehicles, and monitoring for clinical signs of disease.

Although HPAI poses minimal risk to human health when proper precautions are observed, its impact on the poultry industry is significant. Beyond the immediate loss of birds, outbreaks can disrupt trade, increase production costs, and strain resources for disease control. Canada has faced multiple HPAI detections in recent years, reflecting a global trend of persistent viral circulation among wild bird populations.

Producers are urged to remain vigilant and report any unusual mortality or symptoms such as respiratory distress, decreased feed intake, or sudden drops in egg production. Public health officials reiterate that poultry and eggs remain safe for consumption when handled and cooked properly.
