PORTLAND — The Oregon Health Authority is telling beachgoers they can head back into the water at Rockaway Beach in Tillamook County and Seal Rock State Park near Newport.
The health authority had issued health advisories Wednesday after water samples showed higher-than-normal levels of fecal bacteria, which can cause diarrhea, stomach cramps, skin rashes and upper respiratory infections.
Officials said Thursday those levels have subsided.
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.
Officials still recommend staying out of large pools on the beach that are frequented by birds, and runoff from those pools, because the water may contain increased bacteria from fecal matter.
