@justyourluck If 20% of the US milk supply has #H5N1, then we've already effectively done the study, because we don't have a human #AvianFlu pandemic. We would, if it were possible for pasteurized milk to be a significant vector.
Also, we’ve known for decades that pasteurization effectively kills influenza viruses. Pasteurization degrades both the protein capsules protecting viruses and their genetic material. What is in milk after pasteurization are fragments, not whole viruses.
