In Seattle, the majority of the cases have been linked to Matador Restaurant, where the first five people infected dined in August. Three of those five were hospitalized, and one, a 16-year-old girl, developed a kidney disease known as hemolytic uremic syndrome, which can be fatal.

All five people have since recovered, but new cases have cropped up in the weeks since. Two of those were also found in Washington, and the other three were out of state. At least one of those out-of-state cases also dined at Matador during the exposure period. Links to the restaurant have not been identified among the two out-of-state cases.

All together, ten people have now been affected by the outbreak. Seattle health department officials say the E. coli strains in all cases share a similar genetic fingerprint.
