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 CDPH noted that no illnesses connected to the raw milk have been reported, but "due to the ongoing spread of bird flu in dairy cows, poultry, and sporadic human cases, consumers should not consume any of the affected raw milk." If you have purchased any of the product, the CDPH encourages you to immediately return it to your point of purchase.

The detection of bird flu virus this week in a batch of unpasteurized milk sold in California underscores what health experts say are the known and potential risks of the products.
