Abstract
Following reports of highly pathogenic avian influenza H5N1 infections of dairy cattle in the United States in March 2024, we established a Pan-Canadian Milk network to monitor retail milk in Canada. Milk samples from across Canada that had previously tested negative for influenza A virus (IAV) RNA were tested for the presence of anti-IAV nucleoprotein (NP) antibodies as an indicator of past infection of dairy cattle. None of the 109 milk samples tested had evidence of anti-IAV NP antibodies. This is consistent with previous findings from our academic group as well as others including federal testing initiatives that have not found any IAV RNA in milk. Although not surprising given that no cases of H5N1 in cattle have been reported in Canada to date, this work further supports that the extensive outbreak in dairy cattle in the United States has not extended northward into Canada, and the integrity of the Canadian milk supply remains intact.

Viral Immunology coverage includes:
Human and animal viral immunology
Research and development of viral vaccines, including field trials
Immunological characterization of viral components
Virus-based immunological diseases, including autoimmune syndromes
Pathogenic mechanisms
Viral diagnostics
Tumor and cancer immunology with virus as the primary factor
Viral immunology methods.
