E. coli O26 Outbreak Numbers Hit 45 in 6 States

Forty-five people infected with the outbreak strain of STEC O26 have been reported from 6 states. The majority of illnesses have been reported from Washington and Oregon. The number of ill people reported from each state is as follows: California (2), Minnesota (2), New York (1), Ohio (1), Oregon (13), and Washington (26).

Among people for whom information is available, illnesses started on dates ranging from October 19, 2015 to November 8, 2015. Ill people range in age from 2 years to 94, with a median age of 22. Fifty-eight percent of ill people are female. Sixteen (36%) people reported being hospitalized. There have been no reports of hemolytic uremic syndrome and no deaths.

The epidemiologic evidence available to investigators at this time suggests that a meal item or ingredient served at Chipotle Mexican Grill restaurants at several states is a likely source of this outbreak. The investigation has not identified what specific food is linked to illness. Chipotle Mexican Grill is assisting public health officials with understanding the distribution of food items served at locations where ill people ate and this work is ongoing.

State and local public health officials are interviewing ill people to obtain information about foods they might have eaten and other exposures in the week before their illness started. Forty-three (96%) of 45 people interviewed reported eating at a Chipotle Mexican Grill restaurant. The investigation is ongoing to identify common meal items or ingredients causing illness.
