Red Tide isn't Red!
Florida Red Tide
1. Red Tide is a type of Harmful Algal Bloom (HAB) that occurs when there is a higher than normal amount of plant-like microscopic alga, named Karenia brevis (K. brevis).
2. Red Tides can occur at any time of the year. They are most common in late summer and early fall.
3. The first official report of Red Tide in Florida was in 1844. Spanish explorers noted fish kills in Florida waters as early as 1530.
4. Harmful Algal Blooms appear worldwide and occur in fresh and salt water. They are caused by many different species of micro algae.
5. Red Tides are not always red! The water can appear light to dark green, brown or can remain its normal color.
6. K. brevis algae produces a toxin that can affect the central nervous system in fish.
Cooking or freezing does NOT kill the Red Tide toxins in contaminated seafood.
7. Airborne toxins can cause breathing problems in both people and animals.
Common human symptoms include burning or tearing eyes, a cough, and runny or stuffy nose.
8. Manatees, dolphins, dogs and birds can become very ill and die from the toxins.
