Gambierdiscus toxicus. People who have ciguatera may experience
nausea, vomiting, and neurologic symptoms such as tingling fi ngers
or toes. They also may find that cold things feel hot and hot things
feel cold. Ciguatera has no cure. Symptoms usually go away in days
or weeks but can last for years. People who have ciguatera can be
treated for their symptoms.
