Sarasota County Fla. — The Florida Department of Health in Sarasota County (DOH-Sarasota) has issued a health alert for the presence of red tide near Ringling Causeway/ Bird Key Park Beach, North Lido Beach, Lido Casino Beach, Siesta Key Beach, Turtle Beach, Nokomis Beach, North Jetty Beach, Venice Beach, Service Club Beach, Venice Fishing Pier, Brohard Park Beach, and Manasota Key Beach. This is in response to a water sample taken on November 12, 2024. The public should exercise caution in and around this area.
Residents and visitors are advised to take the following precautions if near affected area:
What is Red Tide?
Red tide is caused by high concentrations of a toxin-producing dinoflagellate called Karenia brevis (K. brevis), a type of microscopic algae found in the Gulf of Mexico. Red tide typically forms naturally offshore, commonly in late summer or early fall, and is carried into coastal waters by winds and currents.
At high enough concentrations, K. brevis can discolor water and give it a red or brown hue. To learn more about the appearance of red tide, visit Protecting Florida Together.
Is Red Tide Harmful?
K. brevis produces potent neurotoxins (brevotoxins) that can be harmful to the humans, pets, fish, and wildlife. Wind and wave action can break open K. brevis cells and release toxins into the air. This is why you should monitor conditions and use caution when visiting affected water bodies. People can experience varying degrees of eye, skin, and respiratory irritation from red tide. Sensitive individuals (e.g., children, the elderly, those who are immunocompromised, and those who have chronic respiratory conditions) may be at risk of experiencing more severe symptoms.
For additional information on potential health effects of algae blooms, visit the Florida Department of Health's harmful algae blooms webpage.
Where Can I Find Current Water Status Information?
The Florida Fish and Wildlife Conservation Commission routinely collects and analyzes red tide samples from around the state. Current information about Florida’s water quality status and public health notifications for harmful algae blooms and beach conditions is available at Protecting Florida Together. You can subscribe to receive notifications when water quality changes in your area.
