Subway is under fire after a Canadian television show reported that the restaurant’s chicken products could be made up of less than 50% actual chicken. According to tests performed at Trent University in Canada, the company’s chicken strips and oven-roasted chicken contained just 43% and 54% chicken DNA, respectively, consisting otherwise of soy and other filler ingredients. The sandwich chain denies the allegations. The investigation, which aired last week on the CBC program Marketplace, included DNA tests of chicken products purchased from several fast-food chains in Canada.
