Officials in Washington state are warning consumers to stop drinking raw milk from a local dairy after tests found E. coli in one of the dairy’s raw dairy products.

According to the Washington State Department of Agriculture, raw Jersey whole milk, raw Jersey skim milk and raw Jersey cream from Dungeness Valley Creamery in Sequim, Wash., may be contaminated with E. coli.  

Officials warn that E. coli can produce a toxin called Shiga, which can lead to severe illness. The infection can also cause hemolytic uremic syndrome, which can be especially dangerous for people with compromised immune systems.

They wrote: “On Friday February 22nd we were informed there was a “Cannot Rule Out” (CRO) result on this product for a Shiga toxin-producing E. coli (not 0157H7). We took immediate action and within the same day contacted nearly all retailers and consumers letting them know to discontinue use of this product until further notice and in either outcome, they would receive a full refund. More importantly, there have been no reported illnesses at this time.”

The dairy is working with officials to find the source of the contamination and have placed safety, consumer health and transparency as top priorities. Read their full statement here.
