OTTAWA, Canada (Xinhua) — Preliminary testing has confirmed the presence of H5 avian influenza on a turkey farm near Woodstock area in Ontario province of Canada, according to the Canadian Food Inspection Agency (CFIA) Tuesday.

The agency 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.

Further testing by the CFIA is under way 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.

Initial tests for the disease were conducted on April 5 at the Animal Health Laboratory at the University of Guelph, after the turkey farm experienced sudden deaths of birds over several days.

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 Ontario province, the CFIA, the owner of the infected birds, and the poultry industry are working closely together to manage the situation. Both levels of government will work with the poultry industry to address issues as they emerge. The Canadian poultry sector currently practices a high level of biosecurity that reduces the risk of disease spread.

Avian influenza does not pose a risk to food safety when poultry and poultry products are properly handled and cooked. Avian influenza rarely affects humans that do not have consistent contact with infected birds. Public health authorities stand ready to take precautionary measures as warranted.
