The farm is not a commercial operation, so there is no threat to the national pork supply, according to the USDA.

The U.S. Department of Agriculture (USDA) has confirmed the first case of H5N1 bird flu in a pig in the United States.

USDA issued a statement on Oct. 30 that said the infected pig was discovered at a backyard farm in Crook County, Oregon, where it shared space with poultry that had previously tested positive for the virus.
