What is Ciguatera?
Ciguatera is a form of food poisoning associated with some tropical reef-feeding fish. Not all tropical reefs are affected however, and only some species of fish are susceptible.
It is a naturally occurring marine toxin that accumulates in the food chain. It is passed from fish that feed on algae associated with some tropical reefs, to larger, predatory fish, which are in turn eaten by humans.
While the chances of contracting Ciguatera poisoning are low, it is not uncommon, especially from tropical reef fish caught off the Queensland coast. Most cases of Ciguatera poisoning are a result of consuming recreational catch of large fish.
