According to the FDA, remnants of the bird flu virus have been detected in pasteurized milk, but it won’t infect whoever drinks it.

Experts say that commercial milk remains safe to consume. But what are health officials doing to protect the milk supply, and what about raw milk?

The discovery of viral fragments of avian flu virus in milk sold in U.S. stores suggests that the H5N1 virus may be more widespread in U.S. dairy cattle than previously realized.

The results do not indicate that the virus found in milk is currently infectious, as the pasteurization process works to inactivate viruses.

The Food and Drug Administration on Tuesday announced that genetic fragments from the highly pathogenic avian influenza virus H5N1 have been detected in the pasteurized, commercial milk supply. However,

Testing conducted by the FDA on pasteurized commercially purchased milk has found genetic evidence of the H5N1 bird flu virus, the agency confirmed Tuesday.

The milk poses virtually no risk to consumers, experts said. But the finding suggests that the outbreak in dairy cows is wider than has been known.

Federal agencies with competing interests are slowing the country’s ability to track and control an outbreak of highly virulent bird flu that for the first time is infecting cows in the United States,
