NEW YORK — Chipotle says it has been served with a federal grand jury subpoena as part of a criminal investigation tied to a norovirus outbreak this summer at one of its restaurants in California.
The investigation is being conducted by the U.S. Attorney’s Office for the Central District of California in conjunction with the Food and Drug Administration, the company said in a filing with the Securities and Exchange Commission Wednesday.
Chipotle Mexican Grill says the subpoena requires it to produce a “broad range” of documents.
The Denver company has been reeling since an E. coli outbreak linked to its restaurants, which was followed up by a separate norovirus outbreak in Boston. Chipotle says it expects sales for the fourth quarter to be down 14.6 percent.
