Preventing ciguatoxin exposure is primarily achieved through sourcing fish from approved sources. Ciguatoxin is a harmful toxin produced by certain marine microorganisms and can accumulate in fish, particularly those that feed on smaller fish that have ingested these microorganisms. Approved sources often have strict safety regulations and monitoring protocols in place to ensure that the fish they supply are safe for consumption, thus minimizing the risk of ciguatoxin contamination.

While purchasing fish from private fishermen can provide fresh options, these sources may not always adhere to the same safety standards, making it difficult to ascertain the potential risk of ciguatoxin. Refrigerating fish for two weeks is ineffective in preventing ciguatoxin since the toxin is heat-stable and does not degrade under normal refrigeration. Additionally, while larger predatory fish tend to accumulate more toxins, simply eating fish high up in the food chain does not guarantee safety, as these fish can still carry significant levels of ciguatoxins. Therefore, purchasing from approved sources is the most reliable method for prevention.
