Cases of highly pathogenic avian influenza (HPAI) continue to be confirmed in Lancaster County, Pennsylvania.

The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) reported that the presence of HPAI was confirmed February 10 in a commercial meat turkey flock in the county. In that particular situation, 36,000 turkeys were involved.

APHIS on the same day reported that a flock defined as WOAH (World Organisation for Animal Health) Poultry in Lancaster County was also struck by the virus. However, under WOAH rules, flocks described as such and not as commercial flocks should not affect international poultry trade.

Just one week before that, a commercial table egg laying flock in Lancaster County was confirmed to have been hit by HPAI. Another table egg laying flock in that county was affected by the virus on January 28. Those two flocks collectively involved more than 2.2 million birds.

Since the beginning of 2026, Lancaster County has had three commercial flocks and four flocks described as WOAH Poultry affected by HPAI. Lancaster County also had a commercial meat duck flock hit by the virus in the last week of 2025.

To date this year, Lancaster County is the only Pennsylvania County to have any confirmed cases of HPAI in commercial poultry operations.

Pennsylvania Secretary of Agriculture Russell Redding in a recent press release reminded poultry producers that in the event their flocks become infected, or their operations are temporarily paused due to nearby infections, they can apply for HPAI Recovery Grants, the nation’s first fund dedicated to helping poultry businesses get back on their feet after devastating losses from avian influenza.

Pennsylvania’s HPAI Recovery Fund, which funds the grants, received a total of $75 million in state funding from 2022 to 2024. The fund has $59.45 million in reserve.
