DENVER — Chipotle Mexican Grill has announced it no longer will serve any cheese made with milk from cows treated with the synthetic hormone rBGH (recombinant bovine growth hormone).
 
The move will make Chipotle the first national restaurant chain to eliminate rBGH entirely from items on its menu.
 
Chipotle began serving 100-percent rBGH-free sour cream last year and has begun shifting to rBGH-free cheese over the last several months, a move it will complete by year-end, according to a news release. Chipotle also serves rBGH-free, organic milk at some of its locations.
