A California food company announced it is recalling 153,630 pounds of frozen ground beef after health officials said they found beef tainted with E. coli at a Boy Scout Camp in Goshen, Va.

The meat from S&S Foods of Azusa, Calif., was intended for institutional use and food service companies. The company is attempting to determine whether the “illnesses in Virginia are connected to our operations or have some other original source or cause,” Jeff Grohs, vice president of business development for S&S, said in an e-mail to the Associated Press.

The strain has been linked by the USDA’s Food Safety and Inspection Service and the Virginia Department of Health to the E.coli outbreak at the camp known for hosting Washington area Scouts.

The measure follows another major recall announced earlier this month by Nebraska Beef Ltd. The company decided to recall the beef sent to Nebraska, Colorado, Illinois, Michigan, New York, Pennsylvania and Texas.

At least 73 people who attended the Boy Scout Camp in Goshen, Va., have reported fallen ill, officials said. One person remains hospitalized.

As a measure of precaution, the camp has been closed.

E. coli infection is more often linked to food containing the bacteria. Among the foods that can cause E. coli poisoning are: undercooked ground beef (used for hamburgers), vegetables grown in cow manure or washed in contaminated water. Harmful bacteria are destroyed and the ground beef is safe to consume when it is cooked to 160 degrees Fahrenheit. Health officials recommend that people cook beef (especially ground beef) until is completely cooked through and no longer pink.

The E. coli O157:H7 strain can cause bad stomach cramps, vomiting, diarrhea, sometimes with blood in it. In some cases, it can cause life threatening problems. Children, the elderly and people with weak immune systems are more exposed to the disease.
