H5 AI confirmed on Ontario turkey farm
H5 avian influenza has been confirmed on a turkey farm near Woodstock, Ontario, by Animal Health Laboratory at the University of Guelph. Quarantine measures have been put in place.
Initial tests for the disease were conducted on April 5 after the turkey farm experienced sudden deaths of birds over several days.
Quarantine measures to control AI spread
All birds on the infected premises will be humanely euthanized 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.
The Canadian Food Inspection Agency (CFIA) has placed the farm, and a neighbouring farm, under quarantine to control disease spread and the industry sector has been notified to adopt enhanced biosecurity practices.
Confirming subtype of avian influenza virus
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. Results are expected within days.
