In April, Chipotle announced with great fanfare that it would no longer serve food made with genetically modified ingredients. On Monday, a law firm filed a class-action lawsuit in federal court claiming that the Mexican-style, fast-casual chain’s marketing is misleading and deceptive because it still sells lots of foods made with GMOs. According to the complaint, Chipotle’s meat, cheese, and sour cream is made from animals fed with GMO soy and corn, and the soft drinks it serves are made with corn syrup made from GMO corn.
