Chipotle Mexican Grill has reportedly become the first fast-food chain to disclose the ingredients it uses that contain genetically modified (GM) organisms. The list of items containing GM ingredients is currently available only on the company’s Website and includes barbacoa beef, chicken, fajita vegetables, brown and white rice, steak, and tortillas.

According to its Website, the company’s “goal is to eliminate [genetically modified organisms] GMOs from Chipotle’s ingredients, and we’re working hard to meet this challenge. For example, we recently switched our fryers from soybean oil to sunflower oil. Soybean oil is almost always made from genetically modified soybeans, while there is no commercially available GMO sunflower oil. Where our food contains currently unavoidable GM ingredients, it is only in the form of corn or soy.” See BloombergBusinessWeek.com, June 18, 2013; Chipotle.com.
