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

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

The Canadian Food Inspection Agency (CFIA) reported that on April 23, HPAI was found in a poultry flock 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 it was detected in the rural municipality of Carmichael. Saskatchewan has now had five cases of HPAI in poultry, according to the CFIA, but this is the first case in Carmichael.

The new cases of HPAI in Alberta were reported in Wetaskiwin County, Sturgeon, Rocky View County and Camrose County. Those new cases were all identified as strains of H5N1. The Wetaskiwin and Sturgeon cases were confirmed on April 21, while the Rocky View County and Camrose County cases were confirmed on April 23 and April 24, respectively. This is the second case in Wetaskiwin County and the second case in Camrose County, while it was the first case for the other two counties.

CFIA described the Sturgeon County case as a “small flock.”

All of Canada’s provinces have had confirmed cases of HPAI, although Newfoundland and Labrador, New Brunswick and Prince Edward Island have not had any cases confirmed in commercial poultry.

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