摘　　要：目的:了解2011-2014年深圳市贝类产品的生物毒素污染状况。方法:采集2011—2014年深圳市6个区386份23种贝类样品。依据相关标准用酶联免疫法(ELISA)检测了样品的麻痹性贝类毒素(PSP)、腹泻性贝类毒素(DSP)、神经性贝类毒素(NSP)和遗忘性贝类毒素(ASP)水平。结果:386份样品的毒素超标率为20.21%(78/386),其中PSP超标率3.11%(12/386),DSP超标率18.13%(70/386),未检出NSP和ASP超标样。23种贝类中,有16种DSP超标,3种PSP超标。DSP超标以花蚧、毛蚶、生蚝等贝类最为严重,而PSP超标以圆贝最为突出。结论:近年来深圳市贝类产品存在DSP和PSP污染,应加强卫生监管,确保消费者食用安全。OBJECTIVE： To investigate toxin contaminations of shellfish products in Shenzhen city from 2011 to 2014. METHODS：We collected 386 samples of 23 types of shellfish from six districts of Shenzhen city. We tested and evaluated the levels of paralytic shellfish poison（PSP）,diarrheic shellfish poison（DSP）,neurotoxin shellfish poison（NSP） and amnesic shellfish poison（ASP） in the samples by enzyme-linked immunosorbent assay（ELISA）. RESULTS：There were 78 samples exceeded limits in 386 samples with a over-limit ratio of 20.21%,among which PSP was 3.11%（12/386） and DSP was 18.13%（70/386）. But NSP and ASP were both normal. There were 16 kinds of shellfish with DSP and 3 kinds of shellfish with PSP over limits. DSP contamination was serious in Ruditapes philippinarum,Scapharca subcrenata and Ostrea gigas thunberg,while PSP excess was mostly in Circle Shellfish. CONCLUSION：In recent years DSP and PSP were contaminants in shellfish products in Shenzhen city. We need to strengthen health supervision and guarantee consumer food safety.
