Two years ago, fans of the fast-food chain Chipotle found themselves locked out. That’s because several Chipotle locations were forced to shut down after a major food E. coli outbreak. The outbreak not only caused many customers to fall ill but also had a huge impact on Chipotle’s earnings and reputation. Indeed, Chipotle, which had gained points for doing fast food fresh, suffered two contaminations in two months. The closures, lost revenue, and brand damage were a warning to other service industry providers that failing to properly train and monitor workers can and does come at a very high price. Until recently, it seemed that the chain had recovered. Then, in late July, reports circulated that Chipotle had closed another restaurant in Virginia after several customers fell ill. Once again, the company’s stocks immediately took a huge nosedive.
