A child in California caught bird flu amid a recall of raw milk in the state, but investigations have found no evidence that the case was caused by raw milk.

The CDC's announcement, released Friday (Nov. 22), came two days before a voluntary raw-milk recall by the California-based dairy company Raw Farm. H5N1 can pass into the milk of infected cows, but the pasteurization process eliminates it. Raw milk, which is unpasteurized, may expose people to the germ, officials have warned.

With this latest case, the U.S. has detected 55 total human H5N1 bird flu infections this year, including 29 cases in California alone, according to the CDC. The agency added that there has been no evidence of person-to-person spread of the virus, and for now, the risk to the general public remains low.
