State health and environment officials have issued a health alert for toxic blue-green algae at Kirkman's Cove near Humboldt in the southeastern corner of Nebraska. Officials say in a news release Friday that the alerts were issued following tests of the lake water.
Skin exposed to the toxin from certain strains of blue-green algae can develop rashes and blisters. Someone who drinks water containing the toxin is at risk for headaches, nausea and muscular pain.
