Over a dozen cases of E. coli food poisoning appear to be linked to the Captain’s Galley Seafood Restaurant in China Grove, North Carolina. Diners who became ill ate at the restaurant from May 26 to May 29. Four of the cases have been confirmed as resulting from E. coli.

The Rowan Health Department is investigating the cause of the outbreak, but has not as yet found its source. The restaurant remains open.

Initial symptoms of E.coli infection include severe abdominal cramps and watery diarrhea. The diarrhea may become bloody and can lead to dehydration. Sometimes there are no symptoms at all. There is usually little or no fever.
