Oklahoma E. coli victims ate at Chipotle

However, the latest person did not report having eaten at Chipotle in the week before November 14, when illness started, the CDC document explained.

“All 3 Oklahoma ill people ate at a single Chipotle location in Oklahoma, and the North Dakota ill person traveled to Kansas during their exposure period and at the same Chipotle location as the Kansas ill person”. It said those illnesses started between November 18 and November 26, and all five said they ate at a Chipotle the week before they got sick.

The latest reported cases are being treated as a second outbreak while the CDC investigates whether it is linked to the previous illnesses first reported at the end of October. “Chipotle says it’s helping find which distributor created the problem”.

Following the outbreak, Chipotle Mexican Grill Inc. has said it is implementing new standards to ensure food safety.

Twenty ill people were hospitalized during that outbreak, according to the CDC.

The agency said the five new cases involved an E. coli strain with a rare DNA fingerprint, so they were being considered separately from the earlier outbreak, which sickened at least 53 people in nine states.

There aren’t any reports that any of the victims died during the outbreak. Repeated run ins with E. coli make that a tough promise to sell. Health officials have been unable to trace the E. coli cases to a particular ingredient. This investigation is ongoing, the CDC said.

Earlier this month, Chipotle also closed a restaurant in Boston after dozens of students at Boston College, including members of the men’s basketball team, reported gastrointestinal symptoms.

The more well known strain of E. coli is O157, which is more likely to cause severe cases of illness.

On Dec. 10, Chipotle shares surged after Chief Executive Steve Ells appeared on the “Today” show and said he was sorry for the people who have become sick.

A Chipotle spokesman told CNBC on Monday that the company is “confident” it can achieve a level of food safety risk that is near zero.

They said there are no reported cases at Tulsa Chipotle locations at this time.

Bill Marler, a food poisoning attorney who is representing customers who were sickened after eating at Chipotle, noted the chain had also been linked to other outbreaks of foodborne illnesses in California and Minnesota this summer.
