RICHMOND, Va. – Virginia public health officials said Tuesday that samples of beef taken from a Boy Scout camp tested positive for a strain of E. coli O157:H7.

Spokeswoman Michelle Peregoy reportedly said that the bacteria had been detected in raw ground beef at some of the camps at the Goshen Scout Reservation in Rockbridge County, Va. It matches the strain found in some of the people diagnosed with the illness.

About 67 people who attended camp between July 20 and August became ill with symptoms associated with E. coli, and 16 children and one adult have confirmed cases.

The camp has reportedly closed as a precaution.
