ABSTRACT
<p><b>OBJECTIVE</b>To find out the reason of three ciguatera fish poisoning cases in Xiamen in 2005 and identify the fish species.</p><p><b>METHODS</b>The grouper implicated in food poisoning and seven other coral reef fishes collected from market were tested by mice bioassay and ciguatoxin-test kit. The mtDNA was extracted from toxic grouper meat, and Cty b gene segment was amplified and the PCR products were sequenced. The sequences were compared with those in the GenBank.</p><p><b>RESULTS</b>The result turned out to be positive by the ciguatoxin-test kit, while the toxicity of the toxic grouper implicated in food poisoning was 0.11 mouse unit (MU)/g by mice bioassay. A 475 bp segments of Cty b gene was amplified by PCR and the sequence was 99% homologous with Epinephelus fuscoguttatus (GenBank AY950695).No ciguatoxin in six grouper species collected from market was detected.</p><p><b>CONCLUSION</b>All three food poisoning cases were caused by consumption of ciguatoxin-carrying groupers.</p>
