Federal standards for school meals are intended to keep kids healthy. But with emphasis solely on nutrition, schools are missing another component critical to students' health – exposure to toxic chemicals, according to a study led by Jennifer Hartle, a postdoctoral researcher at the Stanford Prevention Research Center.
School meals may contain unsafe levels of bisphenol A (BPA), a chemical often found in canned goods and plastic packaging, according to the first-of-its-kind study published in the Journal of Exposure Science and Environmental Epidemiology. BPA can disrupt human hormones and has been linked to health effects ranging from cancer to reproductive issues.
"During school site visits, I was shocked to see that virtually everything in school meals came from a can or plastic packaging," Hartle said. "Meat came frozen, pre-packaged, pre-cooked and pre-seasoned. Salads were pre-cut and pre-bagged. Corn, peaches and green beans came in cans. The only items not packaged in plastic were oranges, apples and bananas."
