Ciguatera Fish Poisoning (CFP) is a tropical disease caused by the consumption of fish contaminated with ciguatoxins (CTXs). Currently, only feasible prevention methods for CFP are to avoid certain species from some regions, larger species, or all caught specific regions. Here, we quantified levels P-CTX-1B in Spanish Mackerel (Scomberomorus commerson), which main that causes New South Wales and Queensland, Australia, using LC-MS detection against toxin standard. We found detectable both flesh liver tissues (n = 71, 1.4% prevalence rate, confidence interval 1%-4%, 7% prevalence, 1%-12%, liver, respectively). In small sample there was 46% (19-73%, n 13). Toxin were 0.13 μg kg-1 <0.1 flesh, 1.39 <0.4 indicating tissue had significantly higher concentration (∼5 fold) P-CTX-1B. No apparent relationship observed between length weight S. commerson this study. Footnote.
