Abstract

In this study, liquid chromatography with tandem mass spectroscopy was applied to detect Tetrodotoxin and analogues (TTXs) on pufferfish (Sphoeroides marmoratus) tissues, accidentally found in the stomach of a cuttlefish (Sepia officinalis). The cuttlefish tissues were also analysed. Pufferfish (digestive tract, skin, gonads, liver/spleen, muscle) and cuttlefish (mantle, head/visceral mass) tissues were tested positive for TTXs. In pufferfish, the highest concentration of TTX was found in the digestive tract (4.94 mg/ kg), while in cuttlefish in the mantle (0.21 mg/kg). The presence of TTXs in S. marmoratus was linked to its geographical area of origin while a TTXs cross-contamination of the cuttlefish was hypothesized. Despite the European ban on pufferfish commercialization, campaigns addressed to their morphological identification by consumers and operators might improve its risk management. The risk related to TTXs cross-contamination of edible seafood such as cuttlefish might require specific control measures. Moreover, the collaboration between competent authorities and medical personnel are essential for the monitoring of human poisoning.

河豚毒素（TTX）造成的海产品交叉污染：对不寻常接触途径的管理

本研究采用液相色谱-串联质谱法检测河豚（Sphoeroides marmoratus）组织中的河豚毒素及其类似物（TTXs）。还对墨鱼组织进行了分析。经检测，河豚（消化道、皮肤、性腺、肝脏/脾脏、肌肉）和墨鱼（甲壳、头部/内脏）组织中的 TTX 呈阳性。河豚消化道的 TTX 含量最高（每公斤 4.94 毫克），墨鱼则为每公斤 0.21 毫克。S.marmoratus体内TTX的存在与其原产地有关，而墨鱼体内TTX交叉污染的可能性被推测。尽管欧洲禁止河豚商业化，但消费者和经营者对河豚形态进行识别的活动可能会改善河豚的风险管理。与墨鱼等可食用海产品的 TTXs 交叉污染有关的风险可能需要特定的控制措施。此外，主管当局和医务人员之间的合作对于监测人类中毒至关重要。

期刊介绍： The JCF publishes peer-reviewed original Research Articles and Opinions that are of direct importance to Food and Feed Safety. This includes Food Packaging, Consumer Products as well as Plant Protection Products, Food Microbiology, Veterinary Drugs, Animal Welfare and Genetic Engineering. All peer-reviewed articles that are published should be devoted to improve Consumer Health Protection. Reviews and discussions are welcomed that address legal and/or regulatory decisions with respect to risk assessment and management of Food and Feed Safety issues on a scientific basis. It addresses an international readership of scientists, risk assessors and managers, and other professionals active in the field of Food and Feed Safety and Consumer Health Protection. Manuscripts – preferably written in English but also in German – are published as Research Articles, Reviews, Methods and Short Communications and should cover aspects including, but not limited to: · Factors influencing Food and Feed Safety · Factors influencing Consumer Health Protection · Factors influencing Consumer Behavior · Exposure science related to Risk Assessment and Risk Management · Regulatory aspects related to Food and Feed Safety, Food Packaging, Consumer Products, Plant Protection Products, Food Microbiology, Veterinary Drugs, Animal Welfare and Genetic Engineering · Analytical methods and method validation related to food control and food processing. The JCF also presents important News, as well as Announcements and Reports about administrative surveillance.
