A health advisory was issued today for Fernan Lake by the Panhandle Health District and the Idaho Department of Environmental Quality. Water samples confirmed the presence of the blue-green algae species of Microsystis, Anabaena, and Aphanizomenon - all species can produce potentially dangerous toxins. Precaution is advised. These algae species may produce potentially dangerous toxins. Children and pets are particularly susceptible. In animals, a toxin that may be produced by Anabaena and Aphanizomenon can cause a rapid progression of neurological symptoms such as muscle spasm, decreased movement, labored breathing, convulsions and death. Symptoms have not been documented in people. However, the public is advised to avoid any activity that could lead to ingesting the lake water considering the effect these algal species have on animals/Panhandle Health District. More here.
