The U.S. Department of Agriculture announced on Friday that it will test the national milk supply for bird flu. As of Thursday, 718 dairy herds have been affected in 15 states.
Raw or unpasteurized milk from dairy farms and processors nationwide will be tested on request starting Dec. 16, beginning with California, Colorado, Michigan, Mississippi, Oregon, and Pennsylvania. There is no evidence that humans have ever contracted the bird flu virus as a result of drinking raw milk.
