SHAWNEE, Kan. (AP) — Health regulators say one person who ate at a Chipotle restaurant in Kansas became ill in a new, late November E. coli outbreak that sickened five people in three states.

Kansas Department of Health and Environment spokeswoman Sara Belfry said Monday the person ate at Chiptole’s Shawnee Mission Parkway location the week of Nov. 23. No other details were released.

Jesus Martinez is a kitchen manager at that location. He says food safety is the top priority right now and managers are watching to make sure staff follows health and safety procedures.

The Centers for Disease Control and Prevention says the latest outbreak occurred between Nov. 18 and Nov. 26.

A larger outbreak, which began in October, sickened 53 people in nine states.

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.
