A pig at an Oregon farm was found to have bird flu, the U.S. Department of Agriculture announced Wednesday. It's the first time the virus has been detected in U.S. swine and raises concerns about bird flu's potential to become a human threat.
The infection happened at a backyard farm in Crook County, in the center of the state, where different animals share water and are housed together. Last week, poultry at the farm were found to have the virus, and testing this week found that one of the farm's five pigs had become infected.
