California state officials have suspended a company’s sales of raw milk to retailers amid ongoing concerns about bird flu.

As contradictory and confusing bird flu test results come back from various county and state agencies, the state's agriculture department has instructed raw milk producer Raw Farm to withhold sales.

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.
