Summary: CFP is a seafood-borne illness caused by consumption of fish that have accumulated ciguatoxins (CTXs), which are naturally produced by marine microalgae (Gambierdiscus spp), and are not degraded by either freezing and heating processes. It is well known from Queensland, with more than 1000 cases in the past 15 years, including 2 fatalities, despite only ~20% of cases reported. Internationally, at least 90 different species of fish have been found to be contaminated with CTXs. No study has ever been conducted on the presence of CTXs in fish caught in NSW waters and knowledge about its distribution within Australian waters is poor. As We propose to undertake a well designed sampling and testing program for the presence of CTXs in Spanish Mackerel (Scomberomorus commerson, S. munroi, and S. queenslandicus) caught in NSW. This will enable the revision of guidelines for the management of CFP in NSW.
