Oklahoma and Kansas Now Linked to Chipolte E. coli Outbreak

The FDA, CDC, and state and local officials are investigating a second, more recent outbreak of a different, rare DNA fingerprint of Shiga toxin-producing Escherichia coli O26 (STEC O26) linked to Chipotle Mexican Grill restaurants.

The CDC reports that five people have been reported with the new variant of STEC O26 from a total of three states: Kansas (1), North Dakota (1), and Oklahoma (3).

The Kansas and North Dakota cases ate at the same restaurant in Kansas. The three separate Oklahoma cases all ate at the same Chipotle restaurant.

As of December 18, 2015, 53 people infected with the previously reported outbreak strain of STEC O26 have been reported from nine states: California (3), Illinois (1), Maryland (1), Minnesota (2), New York (1), Ohio (3), Oregon (13), Pennsylvania (2), and Washington (27).

The epidemiologic evidence available at this time suggests that a common meal item or ingredient served at Chipotle Mexican Grill restaurants in several states is a likely source of both outbreaks.

The investigations are still ongoing to determine what specific food is linked to illness.
