Chipotle says carnitas are back on the menu at 90 percent of its restaurants, and that the pork's return to all U.S. restaurants should be complete by the end of November.
The Mexican food chain had stopped serving pork at about a third of its restaurants in January after it said one of its suppliers violated its animal welfare standards. Chipotle has not disclosed the supplier in question, but said the violation centered on how it was housing its pigs.
Denver-based Chipotle Mexican Grill Inc. has enjoyed strong sales growth and expansion by marketing itself as a more wholesome alternative to places like McDonald's and Taco Bell.
