“Testing showed that the same DNA pattern for this strain of E. coli was present in both cases,” Kathryn MacDonald, an agency epidemiologist, said. “We did the testing to make sure that these cases were connected and that this was not just a coincidence.” One of the children, a boy from King County, remains in a Seattle hospital, recovering from the E. coli infection. No new victims have surfaced.

Health officials said if anyone purchased the dairy's raw cow's milk or raw goat's milk they need to either throw it away or take it back to the store where they bought it.
