(Bloomberg) — Chipotle Mexican Grill Inc., still reeling from recent outbreaks of E. coli and norovirus at its restaurants, is now being investigated for its link to a new spate of illnesses in three additional states.

Five people in Kansas, North Dakota and Oklahoma have fallen ill from an E. coli strain with a rare DNA fingerprint, the U.S. Centers for Disease Control and Prevention said Monday in a statement. All five, who became sick on dates ranging from Nov. 18 to Nov. 26, reported eating at a Chipotle in the week before their illnesses started.

The new report may further damage Chipotle’s reputation, which has been battered in recent weeks by an outbreak of E. coli that afflicted at least 53 people in nine states. That was followed by a norovirus contagion at a Boston location that sickened more than 140 college students. The company has estimated that sales will fall as much as 11 percent in the fourth quarter as the illnesses bring attention to the company’s food-safety struggles.
