Avian Influenza in Canada
Avian influenza, commonly known as “bird flu”, is a contagious viral disease that can affect several species of birds used in food production (e.g., chickens, turkeys), as well as pet birds, wild birds and some mammals (see Poultry Farming). The viruses responsible for the disease can be classified into two categories: high pathogenicity or low pathogenicity. The highly pathogenic H5N1 subtype of the avian influenza virus is transmissible to humans. In Canada, cases of avian influenza must be reported to the Canadian Food Inspection Agency.
