Roy Graber reports:

In 2025, 26 states lost commercial poultry or gamebird flocks to highly pathogenic avian influenza (HPAI), but when it came to the number of flocks lost in the United States, close to half of them were in Ohio and Indiana. 

According to data provided by the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) and compiled by WATT Global Media, 285 commercial flocks in the country were lost in 2025. Of those, 137 were in those two Midwestern states.
