Avian influenza continues to spread in Canada

Just days after the highly pathogenic avian influenza (HPAI) in wild birds was confirmed in Manitoba, the province has reported the first case of HPAI in poultry.

In addition, two more new cases have been reported in Saskatchewan and four in Alberta.

The Canadian Food Inspection Agency (CFIA) reported that on April 23, HPAI was found in a chicken herd in the rural municipality of Whitemouth, Manitoba.

In Saskatchewan, the presence of HPAI was reported in a poultry flock in the rural municipality of Morse on April 22, and two days later in the rural municipality of Carmichael. According to the CFIA, there are now five cases of HPAI in poultry in Saskatchewan, but the first in Carmichael.

In Alberta, new cases of HPAI were reported in Waitaskivin County, Sturgeon, Rocky View County and Camaros County. All those new cases were identified as strains of H5N1. Wetskivin and sturgeon cases were confirmed on April 21, while Rocky View County and Camrose County cases were confirmed on April 23 and April 24, respectively. This is the second case in Waitaskivin County and the second in Cameroon’s County, while it was the first for the other two counties.

The CFIA described the Sturgeon County case as a “little herd.”

All Canadian provinces have confirmed cases of HPAI, although no cases have been confirmed in commercial poultry in Newfoundland and Labrador, New Brunswick and Prince Edward Island.

The virus has also been found in commercial poultry in several US states, including Minnesota, Colorado, North Dakota, South Dakota, Nebraska, Kansas, Iowa, Missouri, Kentucky, Indiana, Wisconsin, North Carolina, Delaware, Maryland and Pennsylvania.
