Ciguatera poisoning is caused by a toxin found in certain large predatory reef fish. Which fish is a common source?

Ciguatera toxin builds up through the reef food chain and concentrates in large predatory reef fish such as barracuda, amberjack, and large grouper; it cannot be destroyed by cooking or freezing, so buying from approved, reputable suppliers is the only control. Farmed Atlantic salmon and farm-raised tilapia or catfish never feed on a tropical reef, and canned sardines are small plankton feeders that are heat-processed — none of them is a ciguatera source.
