The Virginia Department of Health was notified of several cases involving ill children Sunday after boys from dozens of Scout troops left the Goshen Scout Reservation outside of Lexington, Va., The Washington Post reported Saturday.

Officials said an additional 60 people who returned from the camp have experienced symptoms that may be from E. coli infections.

Christopher Novak, a Health Department epidemiologist, told the newspaper about 30 workers were trying to find out where the outbreak originated. He said it may have come from packaged meals of vegetables and beef eaten frequently at the camp.

Authorities said infected people included Boy Scouts and Cub Scouts, along with two Maryland residents.

Novak said 10 infected people were hospitalized and six have been released.
