Chipotle May Allow Some Antibiotic-Treated Beef

After years of touting naturally raised meat, Chipotle Mexican Grill Inc. is considering changing its standards to allow beef treated with antibiotics into its restaurants amid a supply shortage.

The burrito seller is evaluating using meat from cattle treated with antibiotics because of an illness, which currently isn’t permitted to be sold in its restaurants, Chris Arnold, a spokesman for Denver-based Chipotle, said in an e-mail. The company still wouldn’t use beef from animals that had been given antibiotics to prevent disease and promote weight gain, he said.
