June 18/San Diego/The Verge -- Chipotle is letting its customers know a little more about its burritos by opening up about the presence of genetically modified organisms (GMOs) within its ingredients. The Mexican-themed fast food restaurant has begun marking all products that include GMOs on the company website, helping to bolster its focus on organic and local foods. According to NaturalNews, this makes Chipotle the first U.S. restaurant chain to include such labels. Eventually, the chain claims it wants to eliminate GMOs from its menu entirely.

While many U.S. grocers specifically sell organic fruits and vegetables, just about everything else -- including prepared food from restaurants -- is rarely labeled. Environmental and consumer advocacy groups have argued that this should change. Though there is debate about whether growing and consuming GMOs leads to adverse effects, there has been no definitive and widely accepted study on their long-term impact on health and the environment. It has become a major issue in many states, and even went to public vote in California last year before ultimately failing. However, enough consumers seem to be interested in the presence of GMOs that it has led grocers like Whole Foods to instate GMO labeling requirements.
