Bird flu has been hitting a little too close to home lately. In its testing of the commercial milk supply, the U.S. Food and Drug Administration (FDA) reported on April 25 that 20% of milk samples tested from the retail market contained “viral fragments” of H5N1 bird flu. Many believe that’s an underestimate; experts at Ohio State University have found that as much as 40% of milk samples from processing facilities in the Midwest may contain parts of the virus.
