For the first time in nearly a year, the virus known as bird flu has been found on a commercial turkey farm in southwestern Indiana.
According to the Indiana State Board of Animal Health (BOAH), a commercial turkey farm in Sullivan County with a flock size of 45,686 was detected with highly pathogenic avian influenza (HPAI).
Sullivan County is along the border with Illinois, with Vigo County (Terre Haute) directly to the north and Knox County (Vincennes) directly to the south.
State health officials did not disclose to Hoosier Ag Today the name of the farm, nor the specific location of the facility impacted.
The last time a positive case was detected in southwestern Indiana was in Washington County in late February 2025.
Since March 2025, all of the reported cases of HPAI have been in northern Indiana on commercial duck, broiler, and egg farms.
Indiana ranks fourth in the U.S. for turkey production, according to USDA. The state also is first in the U.S. for duck production and third for egg production.
Federal officials with USDA add that HPAI does not present a food safety risk, and that cooked poultry and eggs and pasteurized dairy products remain safe to eat.
