DOH-Marion reissues blue-green algae bloom alert for Orange Lake
May 09, 2022
Ocala, Fla. — The Florida Department of Health in Marion County has reissued a Health Alert for the presence of harmful blue-green algal toxins in Orange Lake, near McIntosh.
This is a continuation of a previous Health Alert the department issued for the lake on March 4. This alert is being reissued after a water sample taken on April 21 by the Florida Department of Environmental Protection indicated that toxins were still present.
The public should exercise caution in and around Orange Lake.
Residents and visitors are advised to take the following precautions:
- Do not drink, swim, wade, use personal watercraft, water ski, or boat in waters where there is a visible algae bloom. Do not get water in your eyes, nose, or mouth.
- Wash your skin and clothing with soap and water if you have contact with algae or discolored or smelly water.
- Keep pets away from the area. Waters where there are algae blooms are not safe for animals. Pets and livestock should have a different source of water when algae blooms are present.
- Do not cook or clean dishes with water contaminated by algae blooms. Boiling the water will not eliminate the toxins.
- Eating fillets from healthy fish caught in freshwater lakes experiencing blooms is safe. Rinse fish fillets with tap or bottled water, throw out the guts and cook fish well.
- Do not eat shellfish in waters with algae blooms.
What is blue-green algae?
Blue-green algae are a type of bacteria that is common in Florida’s freshwater environments. A bloom occurs when rapid growth of algae leads to an accumulation of individual cells that discolor water and often produce floating mats that emit unpleasant odors.
Some environmental factors that contribute to blue-green algae blooms are sunny days, warm water temperatures, still water conditions and excess nutrients. Blooms can appear year-round but are more frequent in summer and fall. Many types of blue-green algae can produce toxins.
Is it harmful?
Blue-green algae blooms can impact human health and ecosystems, including fish and other aquatic animals.
