Eight restaurants, a distribution center and two suppliers of restaurant chain Sushi Roll were suspended by the Federal Commission for Protection against Health Risks (Cofepris) due to poisoning of 220 customers.

“After consuming food in these businesses had reported the poisoning of 220 people in two different events, so the Cofepris launched an investigation into the quality of products and health conditions in which the company operates,” said the department in a statement.

“The investigation continues as federal verifiers took 36 samples of food and products for microbiological analysis laboratory and the results will start coming next week,” added the agency.
