April 29, 2016 – Ottawa, ON – Canadian Food Inspection Agency (CFIA)

In early 2016 Highly Pathogenic Avian Influenza (HPAI) was identified in commercial poultry flocks in the United States (U.S.) PDF (1,503 kb) and Mexico. Wild birds, known carriers of the influenza virus, are believed to be the source of the outbreak in the U.S. These outbreaks highlight the importance of biosecurity.

Wild birds are now in migration. As a result, the health of commercial poultry and small flocks is at risk. Avian influenza spreads when wild birds and people (carrying viruses on their hands, boots, tires etc.) come into contact with commercial/small flocks. Producers and small flock owners are encouraged to check their biosecurity plans to stop disease from flying, walking or rolling into their flock.

Farm staff and service providers who are unwell also pose a risk to flock health. Recently two Canadian commercial poultry flocks tested positive for the H1N1 influenza virus. The H1N1 influenza virus causes human respiratory illness and can be transmitted to poultry. In poultry, the infection may go unnoticed, or it may cause mild respiratory illness and decreased egg production. Although the impact of H1N1 is less severe than HPAI, prevention is important to minimize the potential for new viruses to develop in the bird population. Anyone with respiratory illnesses should avoid contact with poultry. For information on influenza and human health refer to the Public Health Agency of Canada.

Commercial poultry producers and small poultry flock owners are encouraged to protect their flocks by checking their biosecurity plans and making sure that their plans are practiced every day.
