Bird flu virus has been found in a batch of raw milk sold in California, and consumers should not drink it, the state Department of Public Health warned Sunday.

No one has gotten sick from the contaminated milk, but the recall serves as an extra caution around the wellness trend that is drinking raw milk.

The County of Santa Clara Public Health Laboratory had identified bird flu in one sample of raw milk purchased at a retail outlet. In response to this positive test, the California Department of Food and Agriculture will begin testing raw milk in bulk tanks for bird flu twice a week — instead of just once.
