The Canadian Food Inspection Agency (CFIA) is investigating a farm in Southern Ontario, near Woodstock, which has experienced recent elevated turkey mortality. Preliminary testing indicates an H5 virus, and further testing is being done to determine the subtype and pathogenicity. A neighboring farm is also under quarantine.
Given the events of this winter, with the rapid eastward spread of HPAI H5, suspicions are running in that direction.
If this turns out to be HPAI H5 (H5N2, H5N8, H5N1, etc.), then this would represent the most eastern detection of these subtypes to date. We should know in a day or two.
OTTAWA, April 6, 2015
Preliminary testing by the Province of Ontario has confirmed the presence of H5 avian influenza on a turkey farm near Woodstock, Ontario.
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. 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.
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.
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 Province of Ontario, 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.
