According to a report released by the Oregon Health Authority over the weekend, the Chipotle Mexican Grill franchise has infected 22 people living in Oregon and Washington with E. coli bacteria, and as a result, 43 Chipotle restaurants, including those located in Portland, have closed across the two states. Because people often do not report E. coli infections, it's likely that more have been infected, and the Authority recommends that anyone who ate at Chipotle between October 14 and 23 and who is experiencing vomiting and bloody diarrhea seek medical help immediately. The cases of E. coli infection come from Oregon's Clackamas and Washington counties and Washington's Clark, King, Skagit, and Cowlitz counties.
A Reuters article reports that this is the third outbreak of food-contamination at Chipotle since August. Chipotle Mexican Grill has over 1,700 restaurant locations, and it was founded in 1993.
