Kansas residents will get a little something extra on their Chipotle burritos starting May 1. Chipotle Mexican Grill will begin using naturally raised meats in its burritos, tacos and salads served in the state of Kansas, in accordance with the company's ongoing commitment to change the way Americans eat.

"We've committed to improve the quality of every ingredient we buy," said Steve Ellis, Chipotle's founder, chairman and CEO in a press release. "In making that commitment, we knew that progress would be difficult - that there was no switch we could throw to be serving better food overnight. But with each step we make in the right direction, we continue to change the way people think about, and eat fast food."

Chipotle has served naturally raised pork for six years. The hogs are free to roam in open pastures, not confined. Chipotle's au naturel plan will convert all of the restaurant's beef and chicken to similar standards of accountability.

According to these standards, all beef and chicken Chipotle uses eat a vegetarian diet with no animal byproducts, do not receive growth hormones or antibiotics, roam in open pasture and a clean, indoor facility and are verified as humane by independent, third-party animal welfare agencies.

"It helps promote sustainable agriculture," said Robby Russell, manager at Chipotle Mexican Grill in Aggieville. "It's about taking the best ingredients from the best sources and using them in our restaurant."

The decision to change to all-natural meats is part of Chipotle's larger campaign to change the integrity of the food it serves, according to the company's Web site.

The campaign, Food With Integrity, is an ongoing quest "to source the highest quality food from farmers who care deeply about the welfare of their animals, their land, and their communities," according to the site.

In addition to its use of naturally raised meats, Chipotle recently began serving sour cream that is free of recombinant bovine growth hormone, a synthetic hormone that increases milk production in cows.

Chipotle also took a step toward exclusively using organic beans. This year, the company approximates 25 percent of the beans it buys will be organically grown, according to the site.

To make the transition economically feasible, employees said a small increase in price is likely, but the amount is not known at this time. However, Russell said given the potential benefit, the decision is justified.

"We definitely feel that it's worth the increase in price, because the food quality will be that much better," Russell said.

Customers at the Aggieville Chipotle said they are happy about the change, regardless of a potential price increase. Some, who said they eat there regularly, said the "all natural" campaign is another complement to the positive aspects of the restaurant.

"Chipotle is great because you can eat once, and you don't have to worry about it for the rest of the day," said Travis Gratton, sophomore in biology. "I think it's important that the food is safe, and whether its organic, that it's healthy."
