Iowa, North Dakota and Indiana all have new confirmed cases of highly pathogenic avian influenza (HPAI), while Minnesota has two new cases, the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported.

All of the affected flocks were commercial turkey flocks, with the exception of the Indiana case, which was a commercial duck flock.

The two cases in Minnesota were a flock of 40,900 in Morrison County, and a flock of 72,000 in Stearns County. The North Dakota case was in Richland County and involved 27,500 turkeys, while the Iowa case involved 29,300 turkeys. These are the first cases for both Bremer and Richland counties.

The duck flock affected by HPAI was in Elkhart County and involved 6,600 birds. This is the third case reported to date in Elkhart County ducks.

The most recent case in Stearns County is the sixth in commercial poultry in that county, all of which were turkey flocks, but HPAI has also been found in one backyard flock there.

Morrison County has had 11 cases, nine of which were in commercial turkey flocks. Also affected there was one layer flock and one broiler flock, according to APHIS.

States to have confirmed cases of HPAI in commercial poultry in 2022 include Minnesota, Colorado, North Dakota, South Dakota, Nebraska, Kansas, Iowa, Missouri, Kentucky, Indiana, Wisconsin, North Carolina, Delaware, Maryland and Pennsylvania. The virus has also been found in commercial game bird operations in Texas, New York and South Dakota.

In addition, every province in Canada has had a confirmed case, although there have not been any cases in commercial poultry in Newfoundland and Labrador, Prince Edward Island, New Brunswick or Manitoba.
