The Canadian Food Inspection Agency (CFIA) has also been testing milk for signs of H5N1 in dairy cows. Canada has had no cases of H5N1 reported in dairy cattle. There's also no evidence of bird flu in samples of commercial milk. "Milk and milk products that have been pasteurized are safe to consume," the Public Health Agency of Canada said.

A teenager in British Columbia, Canada has been hospitalized with a presumed case of H5N1 bird flu, the first detected human case in the country in the current outbreak.

Based on current evidence, the risk of avian influenza infection for the public remains low. The risk of bird flu infection is higher for those who have unprotected exposure to infected animals, PHAC said.
