chipolteThe Mexican food chain, Chipotle, has become the first U.S. restaurant chain to label all ingredients that contain genetically modified organisms (GMOs).

In a statement, Chipotle said it prides itself on its “Food with Integrity,” and was committed to serving high-quality ingredients.

Chipotle posted a list on its website identifying which of its ingredients contain GMOs.

Half of the 24 ingredients on the list were labeled with a red “G” indicating the presence of GMOs.

The GMO-containing ingredients included all tortillas and rice, as well as all varieties of meat, except pork carnitas.

Only two other companies, Whole Foods and Ben and Jerry’s, label GMO ingredients.
