"This Powell, Ohio location of a national burrito chain was closed after dozens of customers reported becoming ill over a weekend; by Wednesday more than 250 people had posted online claiming food poisoning and Ohio’s Department of Health had received over 350 related calls. Complainants reported nausea, vomiting and diarrhea, and a food-safety attorney suggested the outbreak resembles norovirus. The company said its protocols identified a handful of illness reports, it closed the restaurant out of an abundance of caution, conducted an internal investigation while cooperating with the local health department, and planned to reopen; it has not denied responsibility. The incident revived public and investor concern tied to the chain’s well-known 2015–2016 E. coli problems, knocked the stock nearly 10% that week, and prompted analysts and shareholders to pressure the new CEO for a clear account of what happened, what was remedied, and what changes will prevent a recurrence." - Daniela Galarza
