Local health officials have rescinded a health alert issued on September 20, 2024 regarding harmful blue-green algae toxins in Silver Glen Springs.

According to the Florida Department of Health in Marion County (DOH-Marion), follow-up water samples taken at the site did not detect algae toxins, indicating that the public may resume water-related activities.

“It is important that the public exercise caution as blue-green algae bloom status can change when conditions are favorable,” stated DOH-Marion in a press release on Wednesday morning. “Residents and visitors are advised to avoid contact with the water if they see algae blooms.”

Blue-green algae are a type of bacteria that is common in Florida’s freshwater environments. A bloom occurs when a rapid growth of algae leads to an accumulation of individual cells that discolor the water. Floating mats are often produced that emit unpleasant odors.

Environmental factors that contribute to blue-green algae blooms include sunny days, warm water temperatures, still water conditions, and excess nutrients. Blooms can appear year-round, but they are more common in the summer and fall seasons. Many types of blue-green algae are capable of producing toxins.

Blue-green algae blooms can impact the health of individuals and ecosystems, including fish and other aquatic animals. To learn more about the potential health effects of algal blooms, visit the Florida Department of Health’s Harmful Algae Blooms webpage.
