Seven new cases of highly pathogenic avian influenza (HPAI) have been confirmed in commercial turkey operations in Minnesota, while North Dakota, South Dakota and Iowa each have one new case.

These cases were confirmed by the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) on April 3-4, and published on the APHIS website on April 5.

Minnesota avian influenza cases

Of the seven cases in Minnesota, three of those were detected in Kandiyohi County, while Morrison, Becker, Dodge and LeSueur counties each had one case. Two of the Kandiyohi County cases were confirmed in flocks of turkey breeding hens, while APHIS described all of the other new Minnesota cases as “commercial turkey meat bird” flocks.

According to the Minnesota Board of Animal Health, the breeding hen flocks included 49,000 and 20,450 birds, while the Kandiyohi County meat bird flock involved 40,000 turkeys. The state agency reported the Morrison County flock size at 34,000 turkeys, the LaSueur County flock at 22,000 turkeys, the Dodge County flock size at 20,265, and the Becker County flock included 45,000 turkeys.

Prior to these cases, Kandiyohi County and Morrison County had both had one previous case, while these are the first cases for Becker, Dodge and LeSueur counties.

Other Minnesota counties with previous HPAI cases are Stearns, Meeker and Lac Qui Parle.

Other avian influenza cases

APHIS, on April 4, confirmed HPAI in a turkey poult supplier’s flock in Hamilton County, Iowa, as well as in commercial turkey meat bird flocks in Lamoure County, North Dakota, and McPherson County, South Dakota.

The flock size numbers for each infected premises these three states are still being verified by WATT Global Media.

These new cases mark the second for both Hamilton and Lamoure counties, and the third for McPherson County.

So far in 2022, HPAI has been confirmed in commercial poultry flocks in the following states: North Dakota, Kentucky, Delaware, Maryland, Missouri, Iowa, Wisconsin, South Dakota, Indiana, North Carolina, Minnesota and Texas. The Texas case involved pheasants. The virus has also been confirmed in the Canadian provinces of Ontario and Nova Scotia.
