SHERIDAN, Ore. (KOIN 6) — Yamhill County public health officials said Friday it’s possible E. coli was found in a section of the South Yamhill River near Amity and advised swimmers to avoid the area until bacteria levels subside.
Between late July and early August, three people reported becoming ill after swimming in the Green Bridge area of the river. Testing later showed all three people were exposed to the same strain of E. coli.
Officials with the Oregon Public Health Division and Yamhill County Public Health are conducting further testing and have not yet determined the source of the bacteria. Storm water runoff, sewer overflows, failing septic systems and animal waste are common causes.
High levels of E. coli can result in diarrhea, stomach cramps, skin rashes, upper respiratory infections and other illnesses. For more information, contact Yamhill County Public Health at 503.434.7483.
