Abstract: It is well known that tetrodotoxin (TTX) is a potent neurotoxin widely distributed in marine animals. Food poisoning incidents due to ingestion of puffer, gastropod, and goby were reported in Taiwan.1–4 In July 2000, a TTX food poisoning due to ingestion of gastropod Polinices didamy occurred in Chiayi County, western Taiwan.5 It is supposed that TTX-bearers become toxic through the food chain with TTX transferred from lower to higher strata animals, such as starfish to gastropod.6 Judging from this, it is indicated that the source of TTX in Chiayi County might be abundant. To elucidate the food chain of toxin in the toxic gastropods, the benthos collected from the same coastal waters of western Taiwan were analyzed by using TTX bioassay. In contrast, three species of starfish A. scoparius, A. latespinosus and A. polyacanthus were found to contain TTX,6,7 and one species, Asterias amurensis, contained paralytic shellfish poisons (PSP) in Japan.8 In the previous paper, the toxin of starfish A. scoparius collected from Tungkang, southern Taiwan, was mainly composed of TTX (88%) along with minor PSP (12%), and the toxicity in viscera was higher than in the other part.9 In this study, we examined the toxin and seasonal variation of toxicity in the starfish A. vappa in western Taiwan.
