Has bad press taken a bite of Chipotle's sales? One firm thinks so.
Just 9.5 percent of consumers visited a Chipotle Mexican Grill restaurant in December, down from 14.1 percent in November, researchers at Bespoke Market Intelligence estimate.
Since Chipotle was linked to food-borne illnesses in late October, analysts have been predicting declining sales at the fast-casual chain. Those predictions were supported by the new report, which estimates a 30 percent decline in visits over the past three months.
