USDA confirmed H5N1 genotype B3.13 in an Indiana dairy herd through routine milk-testing surveillance, marking Indiana as the latest state with an affected dairy herd. The agency and Indiana officials are investigating the farm and collecting epidemiological information to assess and limit further spread.
Further spread among dairy herds could disrupt milk production and increase biosecurity and testing costs, but the report does not identify a direct supply impact yet.
