OHA Issues Recreational Use Advisory for Cyanotoxin Bloom in Emigrant Lake
The Oregon Health Authority has issued a recreational use advisory for Emigrant Lake in Jackson County due to the presence of a cyanobacteria bloom. OHA officials said people should avoid swimming and high-speed water activities such as water-skiing or power-boating in areas of the lake where blooms are present as the major route of exposure is ingestion of water. Toxins are not absorbed through the skin, but those with skin sensitivities may get a puffy red rash. OHA encourages people to visit Emigrant Lake and enjoy activities such as fishing, camping, hiking, biking, picnicking, bird watching, canoeing and kayaking. Boating is safe as long as speeds do not create excessive spray, which could lead to the risk of inhaling cyanotoxins. Drinking water directly from areas of the lake affected by a bloom is especially dangerous. Toxins cannot be removed by boiling, filtering or treating water with camping-style filters. Contact campground management or the local health department with questions about water availability at nearby campgrounds or day-use areas. Children and pets are at increased risk for exposure because of their size and level of activity. Dogs can get extremely ill and even die within minutes of exposure to cyanotoxins by drinking the water, fetching objects from the water, licking their fur or eating the toxins from floating mats or dried crust along the shore. Exposure to cyanotoxins can be serious and cause a range of symptoms that may be similar to food poisoning such as stomach cramping, diarrhea, nausea and vomiting. Serious symptoms may require medical attention. Fish caught from areas where cyanobacteria blooms are present may pose unknown health risks, so OHA recommends not eating fish from those areas.
