School officials at Oak Ridge Preschool suspect that mouse remains were found in cooked green beans served during lunch. Although no one got ill, around half of the school's 206 students were given the meal. Spokeswoman Karen Cutler said that Aramark Corp., which provides food service management to Oak Ridge and more than 420 other public and private school systems around the country, was investigating the incident. "The object has not been identified. There is no confirmation of what the object is until it is tested," Cutler said. Principal Marian Phillips said the children were oblivious to the problem "because they didn't see anything. The teacher handled it in a way a professional should." Assistant Superintendent Ken Green said all of the cooked green beans and remaining cans were immediately pulled out and the parents informed. Officials believe whatever it was entered the green beans during the "prepackaging process," Green said. Health department official Dr. Paul Erwin assured that the health risk to students is "minimal if any."
