Health officials in California have discovered bird flu virus in raw milk for sale in a store in the state, a development scientists following the ongoing outbreak of bird flu in dairy cows have been anticipating and worrying about for some time.

The H5N1 virus was found in a sample of unpasteurized milk at a store, prompting a recall of one batch. Health agencies have warned against the growing dietary fad.

The U.S. Centers for Disease Control and Prevention on Friday confirmed the country's first case of H5N1 bird flu infection in a child, who experienced mild symptoms and is recovering from their illness.
