The Friday night update comes just days after leading Canadian researchers questioned the country's response to the unprecedented spread of the virus among cows south of the border including the discovery of viral fragments in processed milk.
Canada will now be 'conducting enhanced testing of milk at the retail level' to look for any viral fragments that could signal cases appearing in dairy cattle here.
Milk from dairy cows in Canada goes through pasteurization before being sold, a heating process that neutralizes harmful pathogens like bacteria and viruses.
As noted by the CFIA, the U.S. Food and Drug Administration recently announced its latest research shows pasteurization is indeed effective in inactivating H5N1, even when fragments of the virus remain.
