PORTLAND, Ore.—Oregon Health Authority (OHA) issued a recreational use health advisory today for Cullaby Lake due to the presence of a cyanotoxins above recreational use values (RUVs). The lake is in Clatsop County.  People should avoid swimming and other water activities with a high risk of swallowing water or inhaling water droplets in areas of the lake where blooms are present. Ingestion or inhalation of water is the exposure route of concern. Toxins are not absorbed through the skin. However, those with skin sensitivities may get a puffy red rash.  OHA’s RUVs are designed to protect the most vulnerable, including children, who have a higher activity level and are more likely to swallow water while recreating.  OHA encourages people to visit Cullaby Lake and enjoy activities such as camping, hiking, biking, picnicking, bird watching, and motorized or non-motorized boating activities that have a low risk of swallowing or inhaling water droplets.
