Bird flu is infecting cows across the U.S. Now, scientists have discovered that the virus from infected dairy cows can remain infectious in unpasteurized milk and on the surface of milking equipment for at least an hour.
This means that dairy workers potentially face an increased risk of infection during the milking process. While the risk of drinking unpasteurized, or raw, milk was not the focus of this study, the research does confirm that live viruses can persist in raw milk.
