Abstract
Ciguatera fish poisoning (CFP) is a food borne illness caused by the consumption of fish that contain ciguatera toxins (CTXs). Typically, ciguatera fish poisoning symptoms include gastrointestinal and neurological effects. Ciguatera toxins are secondary metabolites that are produced by marine dinoflagellates, more specifically, of the genus Gambierdiscus. Local government agencies and environmental groups have encouraged the consumption of the invasive Indo-Pacific lionfish (Pterois volitans) whose white flesh tastes similar to a snapper or grouper. Our preliminary results showed that 40% (n = 20) of the lionfish tested from the west end of St. Croix indicated the presence of CTX in their tissue. Results also showed that 15% of the tissue samples had levels above the 0.1 ppb FDA guidance for consumption.
