Chipotle's fresh-food model sickened 1,100 people and cost $25M

Chipotle Mexican Grill built one of the most successful restaurant brands in the United States on 'food with integrity' — fresh, locally sourced, minimally processed ingredients prepared in open kitchens. It grew from a single shop in 1993 to more than 2,000 restaurants, and its shares made it one of the market's darlings.

The same choices that defined the brand made it harder to keep the food safe. Fresh produce and meat that are not frozen, irradiated or heavily processed carry a higher risk of contamination, and a kitchen that prepares from scratch has more points where something can go wrong. As the chain scaled, its food safety program did not keep pace with the number of restaurants it was running.

Between 2015 and 2018 Chipotle was linked to a series of outbreaks — E. coli, norovirus and salmonella — that sickened more than 1,100 people across several states. In 2020 the company entered a deferred prosecution agreement and agreed to pay a $25 million fine, then the largest criminal penalty in a foodborne-illness case. Federal prosecutors said its food safety program had been inadequate.

The damage to the business was severe. Same-store sales fell sharply, the shares lost much of their value, and Chipotle spent years rebuilding its food safety systems and its reputation before traffic recovered.
