Today, the news rolls in that Chipotle Mexican Grill was served a Federal Grand Jury Subpoena in December, following last year's numerous salmonella and nonovirus outbreaks, which made hundreds ill across the nation. The investigation into the company's alleged criminal actions will be led by the U.S. Attorney's Office for the Central District of California, with assistance from the Food and Drug Administration's Office of Criminal Investigations. It doesn't appear that the specific cause of the subpoena is yet known, but ABC News has published speculations that include incomplete food permitting for employees and unclean equipment.
Last fall, an E. coli outbreak caused 43 restaurants to close in Oregon and Washington, and other Chipotle restaurants were linked with disease around the nation. Chipotle announced earlier this week that sales dropped thirty percent in December 2015, and the company has launched aggressive marketing campaigns to improve its image.
