SALT LAKE COUNTY, Utah, Aug. 28, 2018 (Gephardt Daily) — Test results are showing a low level of an algae-related toxin called anatoxin-a in the Jordan River, officials said Tuesday.

The Salt Lake County Health Department said in a news release theĀ EPA “action level” for this toxin is any detection of its presence, so health officials advise people to not enter the water itself, and to keep dogs from entering or drinking river water.

Toxins present at this level have not been shown to present a health threat to people on the surface of the river, such as while kayaking or boating.

“The samples that showed evidence of the toxin were taken from the Jordan Narrows, where the Jordan River enters Salt Lake County,” the statement said. “Additional samples were taken at Blackridge Reservoir in Herriman and at Wheeler Farm East Canal. For public safety concerns officials are advising caution for the entire river as algae and toxins can spread and change quickly.”

The Health Department will post warning signs at Wheeler Farm in Murray and Blackridge Reservoir in Herriman as much of this water comes from the Jordan River and they are popular recreational points. There are no potentially affected water bodies in Salt Lake County that will be closed to access at this time.

The Jordan River will also be monitored and sampled at its entry point into Salt Lake County including Blackridge Reservoir and Wheeler Farm and advisories will be updated as necessary.

“Although blue-green algae are a natural part of many freshwater ecosystems, under the right conditions they can expand rapidly,” the news release said. “High levels of nutrients in the water, combined with warm temperatures, abundant sunlight, and calm water, can promote growth, resulting in blooms that consist of cyanobacteria, often referred to as blue-green algae, a type of bacteria that can create toxins that pose a risk to humans and animals.”

Symptoms of exposure include headache, fever, diarrhea, abdominal pain, nausea and vomiting, and sometimes allergic-like reactions from skin contact.
