Sharon Salyer of the Everett Herald Writer reports that the Snohomish Health District is investigating at least six confirmed cases of E. coli O157:H7.   She reported that Dr. Gary Goldbaum, health officer, said Friday evening that while at least six cases have been confirmed, health officials still don’t know what caused people to become ill.

For readers of my blog, and those who have been following E. coli outbreaks tied to meat or lettuce in Vermont, Colorado, Michigan, Illinois or Canada, another outbreak this month does not seem too surprising.
