A new case of highly pathogenic avian influenza (HPAI) was confirmed in a commercial turkey flock in York County, Pennsylvania.

This marks the first case of HPAI in a commercial poultry flock in the state since it was last confirmed in a commercial duck flock in Berks County on June 2.

The latest infection involved 25,200 commercial turkeys, and the case was confirmed on September 29, reported the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS).

While the York County case is the state’s first commercial turkey flock to be affected by the virus, 18 commercial poultry flocks in the state have been affected, involving the broiler, egg and duck industries. It is also York county’s first case, with all other affected Pennsylvania flocks either being located in Berks or Lancaster counties.

Five new cases confirmed in Canada

In addition to the one new case of HPAI reported in the United States, five new cases have been confirmed in commercial poultry flocks in Canada.

The first of those was confirmed in a commercial flock in Clarence-Rockland, Ontario, on September 29. This is the first case for that particular city, and one of only two reported in the province since May.

The following day, three more HPAI cases were confirmed. One of those was reported in Redburn, Saskatchewan, which is the first of 2022 for that location. The other two were reported in Bifrost-Riverton, Manitoba, bringing the total number of cases in Bifrost-Riverton to four. All four of Bifrost-Riverton’s cases were confirmed in September.

Manitoba had one more case confirmed on October 1, with a commercial poultry flock in Ste. Anne affected, a third case for that rural municipality.

The Canadian Food Inspection Agency (CFIA) announced all five of those cases, but did not disclose information concerning the type of commercial flocks involved, or how large those flocks were.
