Fish caught live and healthy can be eaten if filleted and rinsed thoroughly with fresh water. RED TIDE AND FISH Do not harvest or eat distressed or dead fish (or any animals) from or near a red tide. If you come into contact with red tide, wash off with soap and water, especially if your skin is easily irritated.ĭEAD FISH Red tides can kill fish and other marine life-avoid contact with and don’t swim or walk in these areas. SWIMMING Do not swim in or around red tide because the toxin can cause skin irritation, rashes and burning and sore eyes. If your symptoms do not improve, contact or visit a doctor or call the Florida Poison Information Center at 1-80. For people without asthma or chronic respiratory problems, over-the-counter antihistamines can help. You can get relief from respiratory symptoms by being in an air-conditioned space. Reactions to red tide can be worse for people with asthma, emphysema, bronchitis or any chronic lung disease. Red tide can cause coughing and sneezing and can irritate your eyes, nose and throat. SYMPTOMS? Even if you are not prone to respiratory issues, you should be careful. Respiratory irritation can occur when exposed to brevetoxins. Brevetoxins can be released into the air or water when wind and waves break open the algae cells. Red tide can discolor water to appear red or brown, and it produces potent neurotoxins, called brevetoxins, that can be harmful to the health of both people and animals. brevis), a single-celled, naturally occurring organism belonging to a group of algae called dinoflagellates, is the common cause of red tide in Florida. There are many HAB species in the Gulf of Mexico. For more information available to veterinarians and pet owners, see Education and Resources. Animals can also be impacted by harmful algal blooms. Symptoms should end a short time after the odor disappears or the exposure to the odor ends. If you are irritated by the strong odor or have breathing difficulties, move away from the source of the smell. The smell can cause respiratory irritation, but is not harmful to your health. The results from both studies indicated very low , non-hazardous levels. The Florida Department of Health completed testing in 20 for the presence of hydrogen sulfide in the air during HAB events. While a specific location might not constantly have a bloom, the bloom itself can continue for weeks, months or over a year.Īs some HABs decay, they release a bad odor due to hydrogen sulfide, a foul smelling gas that is a naturally occurring and colorless product of decomposition. It can smell like rotten eggs. The human nose is very sensitive and can smell the unpleasant odor of hydrogen sulfide at very low levels. Blooms can move around and change in a waterbody due to tides, winds and naturally fluctuating amounts of the algae. HABs usually happen in summer or early fall and can affect small and large areas of a waterbody. In Florida, HABs can be found among our saltwater, freshwater and brackish water bodies. Some blooms release toxins that make ecosystems, animals and people sick scientists call these harmful algae blooms (HABs). These foam- or scum-like masses are called blooms and can be pushed to the shore by winds, waves, tides and currents. Algae are plant-like organisms that sustain marine life. They contribute to the food chain and to the oxygen that keeps water bodies healthy, but sometimes, when conditions are right-often warm water and increased nutrients-certain algae can quickly grow and overpopulate.
