The World Organisation for Animal Health (OIE) confirmed that two previously announced cases of highly pathogenic avian influenza (HPAI) in Canada involved commercial duck flocks, while another involved a commercial broiler flock.
On May 5, HPAI was confirmed by the Canadian Food Inspection Agency (CFIA) in a commercial poultry flock in Newell County, Alberta. In its latest report on the Canadian avian influenza situation, OIE announced that that flock involved 38,000 broilers.
CFIA also reported two cases in the York municipality in Ontario. The first of those two cases was confirmed on May 4 and the second was confirmed on May 6. The OIE report revealed that the first case involved 20,000 commercial ducks, while the second involved 24,604 commercial ducks.
OIE has not yet released the sizes and types of birds in each of the HPAI-affected flocks, but of those in which information has been shared, the total number of commercial poultry lost to the virus in Canada in 2022 stands at 1,769,917.
To date, commercial poultry flocks in the provinces of Alberta, British Columbia, Manitoba, Nova Scotia, Ontario, Quebec and Saskatchewan have been affected by avian influenza. However, when wild birds and backyard flocks are included, every Canadian province has had at least one case of HPAI.
The HPAI outbreak began in Canada in December 2021, when the virus was confirmed in birds at an exhibition farm in Newfoundland and Labrador.
Meanwhile, new cases of HPAI continue to be reported in the United States. To date, avian influenza has been confirmed in commercial poultry in the following states: Michigan, Wisconsin, Oklahoma, Minnesota, North Dakota, South Dakota, Nebraska, Kansas, Iowa, Missouri, Kentucky, Indiana, Colorado, North Carolina, Delaware, Maryland, Pennsylvania and Utah.
