Chipotle's ... vision is to change the way people think about and eat fast food. Nothing is more important to us than serving our customers fresh, delicious ingredients that are raised responsibly. Over the years, we have had great success serving the premium beef we call Responsibly Raised, which is produced according to high standards requiring, among other things, that animals be raised without hormones or antibiotics. Sometimes the existing supply of the premium meats we serve is unable to meet our growing demand. This has been the case recently with a portion of the steak we serve, as the size of the total U.S. cattle herd has shrunk to its lowest point in more than 60 years. Returning to grass-based farming systems for cattle is a core component of our long-term vision. Most livestock today spend much of their lives in conditions far from the natural ecosystems in which they evolved. Most cattle spend the latter part of their lives in feedlots, where they are fed grain like corn and soy. There's also evidence suggesting that grass-fed beef is healthier for the people who eat it, and when managed properly, easier on the environment. Over time, we hope that our demand for grass-fed beef will help pave the way for more American ranchers to adopt a grass-fed program. We want to encourage more American ranchers to make the transition to raising cattle entirely on grass.
