HARRISBURG -- Anyone who bought raw milk or raw milk cheese from Stump Acres Dairy in North Codorus Township should throw it away because of possible Listeria contamination, the state Department of Agriculture announced Friday.

Unpasteurized milk collected during an April 24 investigation tested positive for the bacteria, the state said. Testing for Listeria can take as many as 10 days.

Pennsylvania law requires that farms selling raw milk have a permit and be inspected by the state to reduce health risks. Stump Acres' permit was revoked in 2007.

Symptoms of Listeriosis usually appear within three weeks of consumption and include fever, muscle aches, nausea and diarrhea. Infections during pregnancy can lead to miscarriage or stillbirth.

No illnesses have been reported as a result of the contamination, according to the Pennsylvania Health Department.
