POLK COUNTY, Fla. - The Florida Department of Health in Polk County (DOH-Polk) is warning the public about a harmful blue-green algae bloom in the South Central area of Lake Hancock.
Recent water samples taken on June 11th, 2024 confirmed the presence of toxins, prompting the health alert.
Residents and visitors are advised to take the following precautions:

- Wash thoroughly: If you come into contact with algae or discolored water, wash your skin and clothing with soap and water immediately.

What are blue-green algae?
Blue-green algae, also known as cyanobacteria, are a type of bacteria common in Florida's freshwater environments. Blooms occur when rapid algae growth discolors the water and often produces floating mats with unpleasant odors. They can appear as scum, foam, or paint on the water's surface in various colors.
Factors contributing to blue-green algae blooms include sunny days, warm temperatures, still water, and excess nutrients. While blooms can occur year-round, they are more frequent in summer and fall.
Why are blue-green algae harmful?
Some types of blue-green algae produce toxins that can harm humans, pets, fish, and other aquatic life. Even at low concentrations, these toxins can pose risks, particularly for sensitive individuals like children, the elderly, and those with compromised immune systems.
