NEW YORK (AP) -- The Centers for Disease Control and Prevention says it is investigating more recent cases of E. coli cases linked to Chipotle, and that it does not know yet if they are linked to a larger outbreak that began at the end of October.
So far, the agency says five people have been identified in the new outbreak, including one in Kansas, one in North Dakota and three in Oklahoma. It says those illnesses started between Nov. 18 and Nov. 26, and all five said they ate at a Chipotle the week before they got sick.
For the larger outbreak linked to Chipotle, the most recent case had been on Nov. 10.
Chipotle Mexican Grill Inc. has said it is implementing new standards to ensure food safety.
