Aug. 16 (UPI) -- Chipotle employees face another round of food-safety training, CEO Brian Niccol said Thursday, after nearly 650 customers became sick from eating at an Ohio restaurant last month.
Ohio's Delaware General Health District said 647 people reported having gastrointestinal problems after eating at a Chipotle restaurant in Columbus. Stool samples for some of the ill tested positive for clostridium perfringens, a food-borne disease caused by eating food left out at unsafe temperatures.
