The Washington Department of Health warned that milk produced at the Pleasant Valley Dairy in Ferndale, Washington, may be contaminated with Campylobacter this week.  Campylobacter – a bacterium that causes diarrhea, somach cramps, and other symptoms of food poisoning, is one of the most common causes of foodborne illness. 

According to the Seattle Post-Intelligencer:

The bacteria were found in a routine testing sample taken Dec. 11, the department said.

Local health departments are reviewing Campylobacter illness reports that may be related to the milk, the news release said. Symptoms of the illness usually occur two to five days after ingestion and generally last for seven to 10 days.

The milk was sold in half-gallon plastic containers at the Pleasant Valley farm store and at Barganica, Community Food Co-op and Terra Organica in Bellingham; Skagit Valley Co-op in Mount Vernon; Arlington Health, Petosa’s, Manna Mills, Tru Health and Bob’s Corn Patch in Snohomish County; and Spuds in Seattle, the news release said.

The milk has a sell-by date of December 20.
