Incidents of human intoxications throughout Europe, following the consumption of mussels have been attributed to Azaspiracid Poisoning (AZP). Although first discovered in Ireland, the search for the causative toxins, named azaspiracids, in other European countries has now led to the first discovery of these toxins in shellfish from France and Spain. Separation of the toxins, azaspiracid (AZA1) and analogues, AZA2 and AZA3, was achieved using isocratic reversed-phase liquid chromatography coupled, via an electrospray ionisation source, to an ion-trap mass spectrometer. Azaspiracids were identified in mussels (Mytilus galloprovincialis), 0.24 microg/g, from Galicia, Spain, and scallops (Pecten maximus), 0.32 microg/g, from Brittany, France. Toxin profiles were similar to those found in the equivalent shellfish in Ireland in which AZA1 was the predominant toxin.
在欧洲,食用贻贝后发生的人类中毒事件被归因于azaspiracid中毒(AZP)。尽管该毒素最初在爱尔兰被发现,但在其他欧洲国家对致病毒素(即azaspiracids)的搜寻,现已导致在法国和西班牙的贝类中首次发现这些毒素。使用等度反相液相色谱法,通过电喷雾电离源与离子阱质谱仪联用,实现了毒素azaspiracid(AZA1)及其类似物AZA2和AZA3的分离。在西班牙加利西亚的贻贝(Mytilus galloprovincialis)中检测到azaspiracids,含量为0.24微克/克,在法国布列塔尼的扇贝(Pecten maximus)中检测到的含量为0.32微克/克。毒素谱与在爱尔兰同类贝类中发现的相似,其中AZA1是主要毒素。
