水产品中麻痹性贝类毒素的评价及相关研究

Assessment and related research of paralytic shellfish poisons in aquatic products

目的对185批水产品中的麻痹性贝类毒素(PSP)进行评价和相关的方法学研究。方法采用国际公认的标准方法——小鼠生物法,检测水产品中的麻痹性贝类毒素,并与酶联免疫吸附(ELISA)方法进行比对。结果在185批水产品中检测出PSP超过国家标准的产品共5批,超标率为2.7%,小鼠生物法和ELISA方法的评价结果完全一致。结论采用小鼠生物法测得到的PSP检测结果可以为摄入PSP的风险评估提供有力的数据支持。

Objective To assess paralytic shellfish poisons （PSP） in 185 batches of aquatic products and study on the detection methods. Methods The PSP in aquatic products were detected by mouse bioassay, which was the internationally accepted standard method, and compared with the results detected by ELISA method. Results Within 185 batches of aquatic products, there were 5 batches, whose PSP values were higher than the national standard, with the exceeding rate of 2.7%. The assessment results of mouse bioassay and ELISA were exactly the same. Conclusion The detected values of PSP by mouse bioassay can provide strong data support for the risk assessment of PSP intake.
