The Columbian reports that Spanish Sonrise Dairy is recalling whole raw milk because it may be contaminated with E. coli.

The Yacolt dairy announced the recall on Tuesday, after routine sampling by the state Department of Agriculture found E. coli in the raw cream processed from whole raw milk, according to a news release issued by Spanish Sonrise Dairy.

The recall affects raw milk with a “best by” date of Aug. 23. The milk, which was bottled in half-gallon glass containers, was sold directly to private customers and at one retail store, Camas Produce.

E. coli infections may cause severe diarrhea, stomach cramps and bloody stool. Symptoms generally appear three to four days after exposure but can take as long as nine days to appear, according to the news release.

This isn’t the first recall for the Yacolt dairy. Spanish Sonrise issued a recall of raw milk and cream products in April 2015 after routine testing revealed listeria monocytogenes contamination. At the time of the first recall, the owners said they planned to close the dairy.
