目的:分析连云港地区织纹螺食物中毒的流行病学特征,探讨预防织纹螺食物中毒的方法。方法:收集近年织纹螺中毒资料,对连云港地区织纹螺进行形态学鉴定。应用生物测定法检测螺肉中麻痹性贝类毒素(PSP)含量。结果:连云港海域生长4种织纹螺,其中半褶织纹螺导致10起中毒,中毒表现主要是下行性神经麻痹,毒素对温度不敏感。结论:鉴于海洋污染的严重性,为保障海贝的食用安全,应对贝类进行毒素安全指标检测。 Objective: To analyze the epidemiological characteristics of snail food poisoning in Lianyungang and to explore the methods of preventing food poisoning of snail. Methods: The snail poisoning data collected in recent years, Lianyungang region snail morphological identification. Application of bioassay to detect paralytic shellfish poison PSP (PSP) content. Results: Four species of snails were grown in Lianyungang sea area, of which 10 were poisoned by half-folded snail. The poisoning manifested mainly descending nerve palsy, and the toxin was not sensitive to temperature. Conclusion: In view of the seriousness of marine pollution, in order to ensure the safety of shellfish, shellfish should be tested for toxin safety index.
