The Imperial County Public Health Department announced Friday that cyanotoxins were found in the Salton Sea. In recent months, low levels of cyanobacteria, also known as blue-green algae, were detected blooming along the northern shore of the Salton Sea in Riverside County.  Water testing conducted by the California Regional Water Quality Control Board have confirmed the presence of three cyanotoxins: Anatoxin-a, Saxitoxin and Microcystin at the Desert Shores Harbor of the Salton Sea.
