Swimmers, boaters advised to avoid several Central Florida lakes experiencing toxic algae bloom

The Florida Department of Health for Seminole County has just extended an algae bloom alert for three Central Florida lakes.

Swimmers are warned off taking a dip in Sanford's Lake Dot and Lake Kathryn and Lake Griffin in Casselberry because of an ongoing blue-green algae bloom. The warning will remain in effect until July 2.

Blue-green algae produce toxins that can cause health issues not only for humans but whole ecosystems. Swimmers and boaters are encouraged to avoid the lakes.


When a bloom is present, the water is discolored and has a foul smell. If someone comes into a contact with the algae, they should rinse themselves off with soap and water. Pets and other livestock should not drink from the lakes if algae blooms are present.  Fish can still be eaten if caught from a freshwater lake, but it is highly recommended to clean the fish thoroughly the fish and cook it well.
