Nearly 500 foods on grocery store shelves in the United States contain a potentially hazardous industrial plastics chemical, according to a report issued Thursday by health advocacy organization Environmental Working Group, Reuters reported. Azodicarbonamide, also known as ADA, was found in breads, bagels, tortillas, hamburger and hot dog buns, pizza, pastries, and other food products, according to the report. The World Health Organization cited studies that say the chemical "can induce asthma, other respiratory symptoms, and skin sensitization." The FDA states that azodicarbonamide can be used safely if the amount in flour does not exceed 2.05 grams per 100 pounds of flour or 45 parts per million. Subway and Kraft both announced they would be ridding their foods of the chemical
