Detecting notifiable diseases in poultry

Reportable diseases are named under the Health of Animals Act due to their significant impact on animal health, human health or the Canadian economy. These diseases can affect domestic birds from commercial and small-scale breeding, as well as wild birds.

Canada must ensure these diseases are not present in domestic birds at all times. Their rapid detection on farms makes it possible to limit their spread and their disastrous economic impact for the entire sector.

The 4 diseases that must be declared in poultry are:

An outbreak of one of these diseases can have devastating effects on poultry with very high mortality rates. For a detailed description of these diseases and control measures, please consult the Canadian Food Inspection Agency (CFIA) website as well as the EQCMA document Detecting notifiable diseases in poultry .
