Chipotle: First National Restaurant Chain to Serve Free Range Pork

Food With Integrity means working back along the food chain. It means going beyond distributors to discover how the vegetables are grown, how the pigs, cows and chickens are raised, where the best spices come from. We learn how these factors affect the flavor of the finished product. And what we can do to improve it.
Take our carnitas, for example. In pursuing new sources of pork, we discovered naturally raised pigs from a select group of farmers. These animals are not confined in stressful factories. They live outdoors or in deeply bedded pens, so they are free to run, roam, root and socialize. They are not given antibiotics.
Consequently the pork they produce has a natural, moist, delicious flavor. We think it tastes better and is better for you. Our customers love it. And because they do, we buy all we can. By creating a market for meats raised in a healthier environment, we make it worthwhile for these farmers to raise even more. That’s how Food With Integrity works for everyone.
Today we’re doing the same with new sources of chicken, beef, beans, avocados and even lettuce. We’ll be doing it with every item that goes into our menu.
