On Jan. 22, 2025, the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed more H5N1 detections in five states, including a second commercial chicken farm in Georgia, the nation’s top broiler-producing state.

Georgia’s outbreak involves another broiler facility in Elbert County, with 130,400 birds at the location. The state recently ordered a temporary ban on live-bird sales and exhibitions following its first outbreak on a commercial farm.

APHIS also reported outbreaks at broiler farms in two other states, one in Maryland’s Caroline County at a producer with 108,400 birds and another in Virginia’s Accomack County at a location that has 441,000 birds. Last week when announcing the presumed positive in the flock, the Virginia Department of Agriculture and Consumer Services said it is collaborating with counterparts in Maryland and Delaware on a unified response to avian flu incidents on the Delmarva peninsula. 

In Missouri, the virus was confirmed at a large egg-laying farm in Newton County that has 1.175 million birds. Elsewhere, officials confirmed H5N1 at a backyard farm in Oregon’s Umatilla County that has 50 birds.
