Avian Influenza (AI)

Advisories and Updates - Clinical Signs

Highly Pathogenic Avian influenza was detected in April 2015 in a commercial turkey flock in Ontario. In October 2015 Ontario was declared free of avian influenza by the Canadian Food Inspection Agency (CFIA). Poultry farmers and backyard small flock owners are encouraged to implement biosecurity to prevent future outbreaks of avian influenza.

Avian influenza is not a threat to food safety and Ontario poultry is safe to eat. As always, proper cooking times and temperatures, and proper handling techniques should be used with poultry meat or eggs.
