In Mercer County, the new cases involved 22,119 birds at one site and 9,510 at another, both of which are commercial turkey populations. In both cases, the animals involved have been euthanized.

The new cases bring the 2025 totals to 4.24 million birds affected in Jay County, the highest total in Indiana, and 6.11 million in Mercer County. (Darke County is the only county with more cases in Ohio at 8.32 million.)

Adams and Randolph counties are also affected by control areas from cases identified in Jay County. (Adams County has had highly pathogenic avian flu identified at one site this year, with 19,860 birds affected a a commercial turkey operation in late January.)
