Pennsylvania has had its fourth case of highly pathogenic avian influenza (HPAI) in commercial poultry, but the first for a commercial broiler flock in the state.

The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported the new Pennsylvania case, as well as three new cases of HPAI in commercial turkey flocks in Minnesota, were confirmed on April 22.

The new case of HPAI in Pennsylvania, involved a flock of 50,300 commercial broilers in Lancaster County.

The Keystone state’s previous three cases of HPAI involved commercial layer operations, all three of which were in Lancaster County. The first case was confirmed on April 15, while the other two were confirmed on April 20.

There have now been 11 cases of avian influenza in commercial broiler flocks in 2022. Collectively, about 3,500,400 chickens have been affected by HPAI this year.

Avian influenza in Minnesota

HPAI cases in Minnesota turkey flocks continued with the April 22 confirmation of three cases in the state. The largest of which occurred in Swift County, where 127,400 turkeys were involved.

Another 46,000 turkeys were affected in a flock in Yellow Medicine County, while the new case in Otter Tail County included 27,300 turkeys.

To date, Yellow Medicine County has had two HPAI cases, Swift County has had three, and Otter Tail County has had four.

With the addition of these three cases, there have been 105 commercial turkey farms in the United States affected by HPAI. That number does not include breeder and poult flocks, in which there have collectively been 10 cases this year.
