Previously we reported that a significant level of domoic acid, a causative toxin for amnesic shellfish poisoning, was detected
in bivalves belonging to a genus Spondylus from various tropical Asian countries. These findings indicate that causative plankton species for domoic acid widely distribute
in these areas. In the present study, we monitored seasonal change of domoic acid level of Spondylus versicolor in association with that of plankton samples in Nha Phu Bay, Khanh Hoa, Vietnam from December 2004 to October 2005. The toxicity
of S. versicolor showed distinct seasonal variation. During the period when domoic acid level of S. versicolor was increasing, a significant level of domoic acid was detected in the plankton samples, showing the correlation between
these two parameters. These findings show that plankton causative for domoic acid occurred in the bay, and S. versicolor accumulate domoic acid during a bloom of the toxic plankton by food web transfer. 相似文献

Domoic acid was found in bivalves belonging to the genus Spondylus collected randomly from the Philippines, Vietnam, Thailand and Ishigaki Island, Japan. This is the first report of domoic
acid accumulating in bivalves from tropical waters. Large differences in domoic acid levels were observed among the Spondylus specimens collected from different areas. The Spondylus specimens from the Philippines and Vietnam showed higher levels of domoic acid whereas the level in Spondylus spp. from Thailand and Japan was low. The highest level of domoic acid—more than four times the safe consumption level of
20 μg/g whole tissue—was found in a specimen from the Philippines. On the other hand, bivalves other than Spondylus collected from the same area at the same time in the Philippines showed very low levels of domoic acid, showing that bivalves
belonging to the genus Spondylus accumulate specifically high levels of domoic acid. These results suggest the wide distribution of causative phytoplankton
in tropical waters. 相似文献

Tetrodotoxin (TTX) was detected by HPLC and LC-MS/MS in specimens of the horseshoe crab Carcinoscorpius rotundicauda collected from Tan Hai village, Vung Tau province, Vietnam, where cases of poisoning due to the consumption of horseshoe
crab have frequently been reported. The soft tissue from 10 out of the 12 specimens analyzed showed considerable levels of
TTX, making them unsafe for human consumption (81.2 ± 50.3 MU/g). Paralytic shellfish poisoning (PSP) toxins were also detected
in all of the specimens, but the levels were low. These findings show that the frequency of occurrence of C. rotundicauda specimens with a high level of TTX is significantly high, and that the TTX is responsible for the food poisonings caused
by the consumption of C. rotundicauda in this area. 相似文献
