The toxins were found in water samples taken on Oct. 14 around the St. Johns River near Mandarin Point.
Blue-green algae blooms occur when there’s a rapid growth of algae. This can appear as scum, foam, or paint on the surface of the water. The algae tends to discolor the water and can have an unpleasant odor.

The Department of Health said sunny days, warm water temperatures, still water conditions, and excess nutrients are all factors that contribute to algae blooms.
Residents and visitors should not drink, swim, wade, or come into contact with water where there is a visible bloom.
If you do encounter the algae, wash your skin and clothes immediately.
