The Simcoe Muskoka District Health unit has lifted the blue-green algae bloom advisory for Huntsville’s Longs Lake.
Officials say the advisory for the lake’s south shore had been in place since September. Only one advisory is now active in all of Muskoka—for the northwest shore of Mary Lake in Huntsville.
The health unit recommends that people and animals do not drink, swim in, do sports on, or eat fish from the contaminated water– or to use algaecides or herbicides that may break open the algae and release the toxins inside.
Officials say the algae produce toxins harmful to humans and animals, with symptoms including skin irritation, fever, vomiting, and more.
