Ciguatera poisoning is a form of food poisoning caused by consuming fish contaminated with ciguatoxins. These toxins are produced by dinoflagellates, a type of marine plankton, which are then eaten by reef fish. Larger predatory fish, such as barracudas, accumulate these toxins in their tissues as they consume smaller fish. When humans eat these contaminated fish, they can experience a range of symptoms.
