High bacteria levels prompt OHA recommendation to avoid water contact – PORTLAND, Ore.—Oregon Health Authority (OHA) is issuing a public health advisory today for unsafe levels of fecal bacteria in ocean waters at Cannon Beach and Tolovana State Park in Clatsop County. People should avoid direct contact with the water in this area until the advisory is lifted. Unsafe levels of fecal bacteria can cause diarrhea, stomach cramps, skin rashes, upper respiratory infections, and other illnesses. Children, elderly and those with a compromised immune system should use extra caution as they are more vulnerable to illness from waterborne bacteria. Visitors should avoid wading in nearby creeks, pools of water on the beach, or in discolored water, and stay clear of water runoff flowing into the ocean. Levels of fecal bacteria tend to be higher in these types of water sources.
