Troubles continue for restaurant chain Chipotle Mexican Grill, which has been served with a grand jury subpoena in the criminal investigation into the norovirus contamination at one of its restaurants.
The investigation concerns a case of norovirus contamination, a highly contagious virus causing winter vomiting disease, at a California outlet in August.
It was the first of several health scares for the chain last year. More than 50 people in nine states were affected by an E.Coli outbreak in the autumn. And in December, 91 people in Brighton, Massachusetts were infected by norovirus at the restaurant, including Boston’s basketball team.
Shares in the troubled burrito restaurant chain were trading down around five per cent yesterday evening after it was announced the company will have to present range of documents relating to the incident. The grand jury will then decide whether there is a criminal case to answer. Chipotle share price is at its lowest for more than two years.
The investigation is being carried out by the US Attorney’s office for the Central District of California and the food and drug administration's office of criminal investigations.
