The Oregonian today reported on an E. coli outbreak at the Clackamas County Fair in August. According to the story, the Clackamas fair board will put up more signs regarding hand washing for next year’s fair.

Health investigators said today the outbreak spread to one additional person but is now contained. E. coli infections can cause diarrhea, stomach cramps and kidney failure. Those who became sick in August have recovered or are recovering.

This year’s outbreak is larger than the one from the Clackamas County Fair in 2006, when the bacteria infected four people, sending one to the hospital, said William Keene, an epidemiologist for the Oregon Public Health Division.
