Investigators also used whole genome sequencing (WGS), an advanced laboratory technique, to get more detailed information about the DNA fingerprints of the two STEC O26 strains that caused illness. Two different, rare DNA fingerprints of STEC O26 were included in these investigations. PulseNet manages a national database of these DNA fingerprints to identify possible outbreaks. coli bacteria isolated from ill people by using a technique called pulsed-field gel electrophoresis, or PFGE. PulseNet, the national subtyping network of public health and food regulatory agency laboratories, is coordinated by CDC. Public health investigators used the PulseNet system to identify illnesses that were part of the outbreaks. Department of Agriculture’s Food Safety and Inspection Service, and public health officials in several states investigated two outbreaks of Shiga toxin-producing Escherichia coli O26 (STEC O26) infections. Food and Drug Administration External, the U.S.

Take action if you think you have a foodborne illness, such as talking to your healthcare provider, writing down what you ate in the week before you got sick, and answering questions about your illness when public health investigators contact you.ĬDC, the U.S.

They can help stop outbreaks and lessen their impact by keeping detailed records to allow faster tracing of individual shipments of foods from source to destination and to help investigators identify what made people sick.

Food industries are an important partner in making food safer for everyone.

A review of Chipotle’s distribution records by state and federal regulatory officials was unable to identify a single food item or ingredient that could explain either outbreak.

Testing of multiple food items collected from Chipotle restaurant locations did not identify STEC O26.

When a restaurant serves foods with several ingredients that are mixed or cooked together and then used in multiple menu items, it can be more difficult for epidemiologic studies to identity the specific ingredient that is contaminated.

Most ill people in these outbreaks ate many of the same food items at a Chipotle Mexican Grill restaurant.

The investigation did not identify a specific food or ingredient linked to illness.

The epidemiologic evidence collected during this investigation suggested that a common meal item or ingredient served at Chipotle Mexican Grill restaurants was a likely source of both outbreaks.

Isolates tested from ill people in the second, smaller outbreak were not related genetically to isolates from ill people in the initial, larger outbreak.

Investigators used whole genome sequencing (WGS), an advanced laboratory technique, to get more detailed information about the DNA fingerprints of the STEC O26 bacteria that caused illness.

There were no reports of hemolytic uremic syndrome and no deaths in either outbreak.

In the second, smaller outbreak, 5 people infected with a different strain of STEC O26 were reported from 3 states.

In the initial, larger outbreak, 55 people infected with the outbreak strain of STEC O26 were reported from 11 states.

Department of Agriculture’s Food Safety and Inspection Service, and public health officials in several states investigated two separate outbreaks of Shiga toxin-producing Escherichia coli O26 (STEC O26) infections. The most recent illness reported to CDC started on December 1, 2015.

These two outbreaks appear to be over.
