Health officials issue alert after finding blue-green algae toxins in Doctors Lake

FLEMING ISLAND, Fla. – The Florida Department of Health in Clay County issued a health alert Friday after finding harmful blue-green algae toxins in Doctors Lake near Magnolia Road.

The alert came after analyzing the results of a water sample taken on July 16.

According to the DOH-Clay, blue-green algae are a type of bacteria that can be found in Florida’s freshwater environments. When they bloom, algae can discolor water and produce floating mats that emit unpleasant odors. In addition, blooms can also appear as scum, foam, or paint on the surface of the water in various colors.

Officials said the community should be cautious in and around this area and shared a list of safety precautions:

• Do not drink, swim, wade, use personal watercrafts, or come into contact with waters where there is a visible bloom.
• Wash your skin and clothing with soap and water if you have any contact with algae, or discolored or water that smells unpleasant.
• Keep pets and livestock away from the area to avoid any contact with water. Waters where algae blooms are present are not safe for animals. Pets and livestock should use an alternative 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 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 thoroughly.
• Do not eat shellfish in waters with algae blooms.

Health officials said blue-green algae blooms occur more frequently during summer and fall, and some contributing factors to blooms are sunny days, warm water temperatures, still water conditions, and excess nutrients.

According to DOH-Clay, blue-green algae can produce toxins that can be harmful to humans and pets as well as ecosystems, including fish and other aquatic animals.

Sensitive individuals such as children, the elderly, and those who are immunocompromised may still be at risk even at low concentrations of blue-green algae and should avoid any exposure, health officials said.
