In 2015, Mexican fast food chain Chipotle Mexican Grill, had to announce the temporary shutdown of 43 restaurant locations in Oregon and Washington State after people became sick because of E. coli contamination. The company still suffers from sluggish sales and low traffic in its restaurants despite repeated efforts in marketing and sanitation after last year's foodborne illness outbreaks. The news resulted in its shares falling almost 17% in the month since the three earliest cases broke out on October 14, 2015. Though shares have rebounded slightly, the company still trades below the $700 per share it was traded at prior to the scandal. Shares of Chipotle Mexican Grill fell as much as 3.9% today to $423.02 per share.
