摘　　要：为了揭示我国海产贝类腹泻性贝类毒素的污染状况,提高贝类毒素的监测和管理水平,确保海产品的食用安全.从2007年11月至2008年10月在深圳罗湖水产批发市场定期采集产自我国东海和南海海域贝类,共14个贝类品种,186份样品,运用小白鼠生物检测法进行腹泻性贝类毒素检测.结果显示,东海和南海海域贝类腹泻性贝类毒素污染较严重,其中广东沿海贝样检出率和超标率分别为52.54%和40.68%;腹泻性贝类毒素污染程度与贝类种间差异相关,以波纹巴非蛤受毒素污染情况最严重;贝类样品阳性检出率和超标率呈现季节性变化特征,春季和秋季样品毒素含量较高.An investigation was carried out to clarify the pattern of the diarrhetic shellfish poisoning （DSP） in shellfish from the East China Sea and the South China Sea, improve the evaluation of biotoxin in shellfish and insure the seafood safety in our country. The total 186 samples of 14 shellfish varieties were collected from Luohu seafood market in Shenzhen during November 2007 to October 2008 and tested by the mouse bioassay. The results indicated that shellfish were seriously contaminated by DSP. The pos- itive rate and over-standard rate of the samples from the coast of Guangdong province were 52.54% and 40. 68%, respectively. DSP contents in shellfish showed significant difference among shellfish varieties, and Paphia undulata was subject to DSP contamination. The positive rates and over-standard rates changed with seasonal fluctuation, and the samples collected in spring and autumn often contained higher toxin contents.
