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.
