BOSTON (Reuters) – Chipotle Mexican Grill Inc (CMG.N) shares fell to a four-year low on Thursday after testing confirmed Norovirus in a customer who ate at one of the chain’s Virginia restaurants and a video of rodents crawling on the floor of a Dallas shop went viral.
Shares of the burrito chain, which has been under a microscope since it was linked to a string of food safety lapses in 2015, fell 4.5 percent to close at $356.05 on Thursday.
