The presence of blue-green algae has been detected in Lake Jesup, prompting the Florida Department of Health in Seminole County to issue a precautionary warning to the public. While testing of water samples is ongoing, there is a potential for these algae to produce harmful toxins. Given that environmental conditions can change rapidly, residents and visitors are urged to remain cautious, even if toxin presence has not yet been confirmed.
As part of safety measures, individuals are advised to adhere to the following guidelines:
- Avoid drinking, swimming, wading, using personal watercraft, or coming into contact with waters where visible blooms exist.
- If contact with algae, discolored water, or foul-smelling water occurs, it is important to wash skin and clothing with soap and water.
- Pets and livestock should be kept away from affected areas, and alternative water sources should be used during algae blooms, as affected waters are unsafe for animals.
- Do not cook or clean dishes with water contaminated by algae blooms, as boiling does not remove toxins.
- While consuming fillets from healthy fish caught in freshwater lakes experiencing blooms is considered safe, it is crucial to rinse them with tap or bottled water, discard the guts, and cook the fish thoroughly.
- Avoid eating shellfish from waters with algae blooms.
Understanding Blue-Green Algae
Blue-green algae, a type of bacteria, are commonly found in Florida’s freshwater environments. An algal bloom occurs when there is rapid algae growth, leading to an accumulation of individual cells that discolors water and often produces floating mats with unpleasant odors. These blooms can also manifest as scum, foam, or paint-like substances on the water surface, appearing in various colors. Further details about algae blooms can be accessed through the Protecting Florida Together initiative.
Potential Harm from Blue-Green Algae
Blue-green algae have the capacity to produce toxins that pose risks to humans, pets, and ecosystems, including aquatic life. Even at low concentrations, sensitive individuals such as children, the elderly, and those with compromised immune systems may be vulnerable and should avoid exposure.
