Chipotle has reportedly been hit with a lawsuit that claims the chain attempted to conceal a norovirus outbreak.
The class-action, filed on Tuesday, raises questions about an outbreak at a Simi Valley, Calif. location that affected at least 234 customers, NBC reports. The lawsuit states that a kitchen manager who was suffering symptoms continued to work at the restaurant from Aug. 18 until he was diagnosed with norovirus two days later. It says that when at least two customers had complained they were suffering symptoms, Chipotle attempted to cover up the outbreak instead of immediately alerting authorities.
