Frozen ground beef linked to an E. coli outbreak at a Rockbridge County Boy Scout camp was voluntarily recalled Thursday.

California-based S&S Foods LLC. has recalled approximately 153,630 pounds of frozen ground beef products because the meat may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service said in a press release.

The recall comes on the heals of a Virginia Department of Health discovery that showed 11 of the scouts with confirmed cases of E. coli was tied to tainted beef found at the camp.

"We were able to determine that 11 are linked to the beef recall that was announced today by the department of agriculture," said Bobby Parker, a spokesman for the health department.

State health investigators had previously linked the strain of E. coli found in stool samples of the children to a package of beef at the camp.

The 30-pound boxes of recalled frozen meet are sold only for food service and institutional use and are not for direct retail purchase. The meat involved in the recall was shipped to distribution centers located in Milwaukee, Wis., and Allentown, Penn., according to the FSIS.

Messages left for comment with FSIS and S&S Foods were not immediately returned.
