WOAH declares HPAI “resolved” in Canada’s poultry flocks

The World Organization for Animal Health (WOAH) has stated that Canada’s poultry flocks are now resolved from the highly pathogenic avian influenza (HPAI) outbreak that began in late 2021.

The outbreak has spread across both commercial poultry and wild birds across North America, with the first case being recorded in December 2021 in Newfoundland and Labrador. Since then, it has spread across flocks in Canada and the U.S. At no point did any of Canada’s territories, or Atlantic Canadian provinces record cases in commercial poultry flocks.

“Surveillance is ongoing in the affected areas. HPAI outbreaks in poultry are now considered resolved and all zoning restrictions have been lifted in the following provinces: New Brunswick, Nova Scotia, Manitoba, Saskatchewan, Ontario, Quebec and British Columbia. Wildlife surveillance as well as the Canadian Notifiable Avian Influenza Surveillance System (CanNAISS) activities for poultry are ongoing in Canada,” the WOAH wrote in the statement.

Quebec has been widely considered the epicentre of Canada’s outbreak. The last detection was recorded on May 6 and was since revoked.
