2nd case of AI in Ontario found on broiler breeder farm
Preliminary testing by the Province of Ontario has confirmed the presence of H5 avian influenza on a second farm in Oxford County, Ontario. The farm is a broiler breeder chicken farm.
The Canadian Food Inspection Agency (CFIA) has placed the farm under quarantine to control disease spread and the poultry industry has been notified to adopt enhanced biosecurity practices. Further testing by the CFIA is underway to confirm pathogenicity and to determine the precise subtype and strain of the virus. Pathogenicity refers to the severity of the illness caused in birds.
Tests conducted after sudden deaths of birds
Initial tests for the disease were conducted on April 17, 2015 at the Animal Health Laboratory at the University of Guelph, after the chicken farm experienced sudden deaths of birds over several days.
All birds on the farm to be culled
All birds on the infected premises will be humanely destroyed and disposed of, in accordance with provincial environmental regulations and internationally accepted disease control guidelines. As lead response agency the CFIA will ensure the quarantine of the infected farm, and determine a surrounding surveillance zone for further testing and movement control measures. The CFIA will also lead on required depopulation of birds, while the Province will provide technical support on required carcass disposal. Once all birds have been removed, the CFIA will oversee the cleaning and disinfection of the barns, vehicles, equipment and tools to eliminate any infectious material that may remain.
