Chipotle: food-safety outbreaks and a long recovery

What happened
Chipotle built its brand on ‘food with integrity’ — fresh, locally sourced ingredients. In 2015 multiple outbreaks of E. coli, norovirus, and salmonella were linked to its restaurants across several states, sickening hundreds of people. The brand promise itself became a liability.
Comparable sales fell by about 30% in early 2016 and the share price roughly halved from its peak. Chipotle closed all its restaurants for a few hours on 8 February 2016 for a company-wide food-safety meeting, introduced new procedures such as preparing some ingredients centrally, and offered free burrito promotions to win customers back. Further incidents in 2017 slowed recovery.
Brian Niccol, from Taco Bell, became CEO in 2018 and invested in digital ordering, drive-through ‘Chipotlanes’, and marketing. Sales recovered strongly, and the share price later rose far above its previous peak.
