Highly pathogenic avian influenza (HPAI), commonly known as bird flu, has been confirmed at a commercial poultry operation in central Indiana, near Indianapolis.
The Indiana State Board of Animal Health (BOAH) reported that the virus was detected at a commercial breeder turkey farm in Boone County housing 18,763 birds. This marks the first confirmed case of HPAI in central Indiana since January 2025, when the virus was identified in a small, non-commercial hobby flock of 44 birds in Shelby County.
In response, state animal health officials have established a 10-kilometer (6.2-mile) control zone surrounding the affected Boone County site, covering parts of Boone and Clinton counties. Poultry and dairy farms within this area will undergo testing for the virus. Additionally, a 20-kilometer (12.4-mile) surveillance zone has been implemented across portions of Boone, Clinton, Hamilton, and Tipton counties.
Another case was confirmed Tuesday evening at a commercial meat duck farm in Elkhart County, where nearly 3,000 birds are raised. Officials have not released the names or precise locations of the impacted farms.
Earlier, on Sunday evening, BOAH announced a separate HPAI detection at a commercial turkey farm in Sullivan County, located between Terre Haute and Vincennes in southwestern Indiana. That farm houses 45,686 birds.
According to the U.S. Department of Agriculture (USDA), Indiana ranks fourth nationally in turkey production. The state leads the nation in duck production and ranks third in egg production.
Federal officials emphasize that HPAI does not pose a food safety risk. Properly cooked poultry and eggs, as well as pasteurized dairy products, remain safe for consumption.
