RALEIGH, N.C. (AP) -- Officials are warning about the dangers of raw milk after eight cases of illness in North Carolina were traced to a South Carolina dairy.

The Food and Drug Administration along with two North Carolina agencies says three definite and five likely cases of a bacterial ailment have been linked to raw milk from the Tucker Adkins Dairy in York, S.C.

Raw milk carries a higher risk of potentially harmful bacteria than milk that has been pasteurized. The bacteria in the North Carolina cases can cause vomiting, diarrhea, and other symptoms.

North Carolina prohibits the sale of raw milk to consumers, although it's legal in South Carolina. But it's illegal to transport raw milk across state lines for human consumption.

A call to the dairy was not returned Monday evening.
