There has been recent detection of multiple avian influenza viruses into North America (Canada and United States). These viruses are apparently spread by migratory birds. These influenza viruses have been detected in captive birds, backyard poultry and commercial poultry flocks in 20 different states and provinces in USA and Canada. This situation is UNPRECEDENTED in the history of North America.

These viruses appear to be related to an influenza virus that has been circulating in Asia and Europe throughout 2014. This group of influenza viruses is highly pathogenic to birds, making them severely sick and in many cases inducing high mortality in birds up to 90%. However, they seem to represent a low risk for human infection, so poultry and poultry products are safe to consume when they are properly handled and cooked.
