Quoting the front of the box: "CRUNCHY toasted CHEESE - NOTHING ELSE." Ingredients listed: Cheese (Pasteurized Milk, Salt, Cheese Cultures) Enzymes, Annatto (for color). Contains Milk. NO MSG, NO WHEAT OR WHEAT PRODUCTS, GLUTEN FREE. Box does not state anything about GMO ingredients, but there is no corn nor soy. I suggest you contact the manufacturer at: 800-367-1711. Hope this info is helpful.
