Nobody Can Figure Out Why People Got Sick at That Chipotle

"A restaurant in Delaware County, Ohio is at the center of a large foodborne-illness investigation after more than 700 inquiries and over 500 interviews; several stool samples have been collected but investigators say they currently have no leads. Tests on patient samples have come back negative for common culprits—including salmonella, shigella, E. coli, and norovirus—so leftover food is still being tested to try to identify the cause. The incident is being viewed in the context of multiple recent outbreaks tied to the chain (including an unresolved multi-state E. coli episode in 2016), raising broader concerns about food-safety practices in the fast-food industry." - Chris Crowley
