Chipotle E. Coli Outbreak Expands to Illinois

The majority of the illnesses have been in Oregon and Washington, where cases were initially reported at the end of October

An outbreak of E. coli linked to Chipotle has expanded to nine states, including Illinois, with a total of 52 people being sickened.

The Centers for Disease Control and Prevention said Friday there were seven additional illnesses, including in three more states — Illinois, Maryland and Pennsylvania. The most recent illness started on Nov. 13, it said.

The majority of the illnesses have been in Oregon and Washington, where cases were initially reported at the end of October. Additional cases were later reported in California, Minnesota, New York and Ohio.

The CDC had said in late November that additional cases could be reported for illnesses that started after Oct. 31.

Of the 52 people infected, the CDC says 47 reported eating at a Chipotle restaurant the week before the illness started. The agency has not yet determined the ingredient that made people sick.

Earlier Friday, Chipotle said it was tightening its food safety standards.

The Denver-based chain known for touting the quality of its ingredients said it hired IEH Laboratories in Seattle to help improve its procedures. It said it will implement testing of all produce before it is shipped to restaurants and enhance employee training for food safety and handling.

Chipotle has not yet said how sales have been affected by the bad publicity from the outbreak, but plans to provide a financial update before a presentation for analysts and investors Tuesday. In October, the company had forecast sales at established locations would be up in the low- to mid-single digit percentages for 2015.

The company's shares fell 2.5 percent to $551.16 in trading Friday afternoon.

Chipotle said it tested ingredients before, but that it is moving to testing smaller batches and a larger number of samples.

"In testing for pathogens, in many ways you're looking for needles in haystacks. Through this high resolution testing program, we are making the haystacks smaller by working with smaller lots," the company said.

It said that no ingredients that are likely to have been connected to the incident remain in its restaurants or supply system.

Chris Arnold, a spokesman for Chipotle Mexican Grill Inc., said the company's local produce suppliers may not all be able to meet the new standards. The company noted that its local produce program accounts for a "relatively small percentage" of the produce it uses, and only runs from around June through October in most parts of the country.
