MARION COUNTY, FL (352today.com) – The Florida Department of Health in Marion County (DOH-Marion) has issued a cautionary notice regarding the presence of blue-green algae at Lake Weir’s Hope Boat Ramp and Hampton Beach. The advisory, issued on Feb. 19, 2025, urges residents and visitors to avoid contact with the water while testing is underway.

Blue-green algae, a type of bacteria common in Florida’s freshwater bodies, can produce toxins that pose health risks to humans, pets, and aquatic life. Environmental conditions can change rapidly, making it essential to exercise caution even if toxin levels have not yet been confirmed.

Health officials advise the public to avoid swimming, wading, drinking, or using personal watercraft in visibly affected areas. Those who come into contact with discolored or foul-smelling water should wash thoroughly with soap and water. Pets and livestock should also be kept away, as the water may be unsafe for animals.

The Florida Department of Environmental Protection (DEP) and its partners are monitoring the bloom, collecting samples, and analyzing toxin levels. Updates can be found on the DEP’s Algal Bloom Dashboard and Protecting Florida Together website.

Blue-green algae blooms typically occur in warm, still waters with excess nutrients and can appear as floating mats, scum, or foam in various colors. They are most common in summer and fall but can happen year-round.

For health concerns related to algae exposure, residents can contact the Florida Poison Information Center at 800-222-1222 or DOH-Marion at 352-622-7744. Reports of fish kills, wildlife issues, or additional bloom sightings can be made to the Florida Fish and Wildlife Conservation Commission at 800-636-0511.
