Is red tide toxic to humans?
Most people are safe in the water. Florida red tide can cause some people to suffer skin irritation and burning eyes. The blooms may cause respiratory irritation for people with respiratory illness. Red tides are caused by a combination of bacteria, viruses, algae, and other microscopic organisms that live in warm, nutrient-rich water.
These organisms can survive in water that is too hot or too cold for them to survive naturally. When these organisms die, they release toxins into the water, which can be harmful to people and animals. If you are exposed to these toxins, you may experience symptoms such as fever, chills, headache, muscle aches, nausea, vomiting, diarrhea, or diarrhea-like symptoms.
In some cases, these symptoms may be severe enough to require hospitalization. You should also consult your doctor if you have any of the following symptoms: nausea or vomiting that lasts more than a few hours; difficulty breathing or swallowing; or a change in your vision or hearing.

Boiling does not destroy the toxin. The water that the shellfish are cooked in doesn’t remove all of the toxins. The best way to determine if your oysters are infected is to take a sample from the bottom of your tank.
You can do this by placing a piece of plastic wrap over the top of a glass of water and submerging the entire tank in it. If you can’t see any water in the glass, it’s safe to assume that you have an Oyster infestation.
