PORTLAND, — The Oregon Health Authority is telling beachgoers, particularly children and the elderly, to stay out of the water for now at Rockaway Beach in Tillamook County and Seal Rock State Park near Newport.

The health authority says water samples show higher-than-normal levels of fecal bacteria, which can cause diarrhea, stomach cramps, skin rashes and upper respiratory infections.

Increased bacteria levels in the ocean can come from both shore and inland sources, including animal waste, stormwater runoff, sewer overflows and failing septic systems.

Besides the ocean, beachgoers should avoid wading in nearby creeks and pools of water on the beach.
