California public health officials warn consumers not to drink a batch of raw milk from a Fresno-based company after it tested positive for bird flu.

Last Sunday, Fresno-based Raw Farm voluntarily recalled a first batch of cream top whole raw milk with a "best by" date of November 27. By Wednesday, the California Department of Public Health announced that a second batch of Raw Farm cream top, with a "best by" date of December 7 had also tested positive for bird flu, based on retail sampling.

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.
