Chipotle Mexican Grill is snakebit. Yet another restaurant has had to go offline from food-borne illness. This time under the chain's new CEO. For some reason, Chipotles nationwide have suffered from poisoning outbreaks. The firm has changed its sourcing, logistics and cleanliness practices but to little avail. It just can't get it right and the public has responded by staying away from its burritos. This is a chronic PR crisis for the company and one it must solve sooner rather than later. There are many ways viruses and bacteria can enter a food chain, and a restaurant company needs to guard against all of them. It doesn't have the leeway of occasional lapses. The CEO will have to bear down on procedures to make sure it doesn't happen again.
