The investigation into an outbreak of E. coli O26 illnesses that may be related to Chipotle restaurants in Washington and Oregon has grown from 19 reported Washington cases to 25 as of today. The Washington State Department of Health continues working closely with local, state, and federal partners on a disease investigation to learn the extent of the outbreak and possible sources of E. coli O26 bacteria.
In Washington, residents of Clark (11), Cowlitz (2), Island (2), King (6), and Skagit (4) counties have been reported as outbreak cases. Of the 25 cases, 23 reported having been at Chipotle restaurants before getting sick. Nine of the Washington residents were hospitalized. Cases range in age from five-to-60. The Washington Department of Health said there are five Washington restaurants associated with this outbreak: Hazel Dell, 7715 NE 5thAvenue, Suite 109, in Vancouver; 1404 Broadway Avenue and 4229 University Way NE in Seattle; 512 Ramsey Way 101 in Kent; and 1753 S. Burlington Blvd. in Burlington.
The Oregon Health Authority is reporting a total of 12 cases of Shiga toxin E. coli O26 linked to eating at Chipotle restaurants in the Portland Metro area, up from three cases that were first reported October 31.
Among the cases, three were hospitalized. There have been no deaths. People in Multnomah, Clackamas and Washington counties, as well as Columbia, Benton and Deschutes counties have reported symptoms.
Many people affected with Shiga toxin E. coli O26 may not seek health care, so the number of people made ill by this outbreak is likely more than identified.
