Raw, unpasteurized milk is a known vector of bird flu when derived from infected cow herds. It can also contain pathogens such as E. coli, salmonella, and both Streptococcus and Staphylococcus bacteria.

Collection and testing of raw milk cheese will be done by the FDA amid outbreaks of the illness in several states.

FDA may impose measures ‘such as a recall, follow-up inspection or other possible responses to protect public health’
