During red tide, whelks and moon snails can accumulate dangerous levels of the toxin as they feed on contaminated shellfish. During red tide blooms, hard-shell clams, soft-shell clams, oysters, mussels, whelks, and moon snails are not safe to eat, according to the National Oceanic and Atmospheric Administration.
Red tide is caused by a combination of factors, including pollution from human activities, climate change, ocean acidification, overfishing, coastal development, invasive species, nutrient runoff from agriculture and urban runoff, as well as human-induced changes in the ocean’s chemistry, such as the loss of calcium carbonate (CaCO 3 ) from the seafloor and the release of carbon dioxide (CO 2 ) and methane (CH 4 ) as a result of fossil fuel burning and deforestation.
What happens if you eat seafood from red tide?
Recreational fishermen must be careful: Do not eat mollusks (clams or oysters) taken from red tide waters, as they contain toxins that cause a food poisoning called NSP (Neurotoxic Shellfish Poisoning). If the finfish have not been killed by the toxin, they can be eaten.
What can you eat during red tide?
As long as the fish isn’t sick, it’s okay to eat it. Red tide is caused by algae blooms in the Gulf of Mexico. The algae, which can grow up to 1,000 feet (305 meters) high, can be harmful to humans and other marine life.
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. Red tides can cause respiratory irritation for people with respiratory illnesses. If you think you may have been exposed to the red-tide, you should contact your health care provider right away.

Can you get sick from red tide?
Brevetoxicity, also known as “shellfish poisoning”, can be caused by eating red tide-contaminated shellfish. Brevetoxicosis is a rare but serious condition in which the body’s immune system attacks its own tissues and organs. Symptoms include nausea, vomiting, diarrhea, abdominal pain, fever, chills, headache, muscle aches, and fatigue. It can be fatal if not treated promptly.
The symptoms can last from a few hours to several days, but they usually resolve on their own within a day or two. If you suspect that you or someone you know may be suffering from this condition, call your doctor immediately.
How long does red tide sickness last?
According to the study, only one hour of exposure to Florida red tide aerosols can cause increased symptoms and decreased respiratory function for at least 24 hours. “This is the first study to show that long-term exposure of asthmatic patients to red tides is associated with increased respiratory symptoms,” said lead author, Dr. Michael J. O’Brien, a professor of medicine at the University of Miami Miller School of Medicine.
“This study is important because it shows that the symptoms of asthma and other respiratory diseases can be worsened by long term exposures to these toxins. This is especially important in light of the fact that many people with asthma are not aware that they have the disease and may not seek medical care for it.
The findings of this study are also important for the public health community because they suggest that people who live in areas with high concentrations of these toxic substances should be aware of their symptoms, and they should take steps to protect themselves from exposure.” The research was funded by the National Institute of Environmental Health Sciences (NIEHS), the U.S.
