Bird flu has landed on a California farm that shuns virus-killing pasteurization, leading to a second recall of raw milk and a suspension of operations at the company, Raw Farm in Fresno County.

California health officials are warning not to drink another lot of raw milk from Fresno-based Raw Farm after it tested positive for bird flu virus. More testing of Raw Farm products is underway, the state said.

The detection of bird flu in raw milk again highlights safety concerns about a practice promoted by social media influencers and right-wing figures, including Robert F. Kennedy Jr.
