The FDA is waiting on test results on the effects of pasteurization on the virus in cow's milk, but to date, it's seen nothing that would change the assessment that commercial milk is safe.

The Food and Drug Administration said Tuesday that fragments of the bird flu virus had been detected in some samples of pasteurized milk in the U.S. While the agency maintains that the milk is safe to drink, it notes that it is still waiting on the results of studies to confirm this.

The findings come less than a month after an outbreak of the H5N1 strain of bird flu was found, for the first time, in herds of dairy cows in several states. It has since been detected in herds in eight states. ⠀

The FDA is specifically testing whether pasteurization inactivates bird flu in cow milk. The findings will be available in the “next few days to weeks,” it said. ⠀

Still, the virus remains a cause of concern among health officials, given its particularly high mortality rate of around 50%. Bird flu doesn’t spread easily from person to person, but there’s worry that it could mutate as it spreads among cows to a version that spreads more easily among people. So far, there’s no evidence indicating that has happened, according to the CDC.

    There is a very big difference between the headline of “Bird flu virus found in pasteurized milk” and the real message “fragments of the bird flu virus had been detected in some samples of pasteurized milk in the U.S.”. Turning potential health hazards and threats into harmless particles is the very job of pasteurizing. That is excactly why we pasteurize milk.

    Heck, the virus particles could even evoke immune reactions, thus vaccinating us in a natural way. Just by drinking milk.
