麻痹性贝类中毒（PSP）是由石房蛤毒素和相关化合物引起的，通常是由于食用了滤食性软体动物贝类，这些贝类集中了海洋甲藻的毒素。除了这些微藻来源，石房蛤毒素和相关化合物，在这篇评论中被称为STXs，也产生于淡水蓝藻，并已与钙质红藻。STX在整个水生食物网中转移和生物累积，并可传播到陆地生物群，包括人类。在若干非传统（即非滤食性）病媒中，已经记录了因STX导致的渔业关闭和人类中毒。这些包括但不限于海洋腹足类动物（食肉和放牧）、甲壳类动物和通过毒素转移获得STX的鱼类。通常由于空间、时间或物种与STX（水华形成甲藻）的主要来源的断开，对这种非传统PSP载体的监测和管理一直具有挑战性。一个简短的文献综述提供了过滤器喂养（传统）和非过滤器喂养（非传统）载体的STX与具体参考人类的影响。我们包括几个案例研究有关的管理行动，以防止PSP，以及食物中毒事件的STX（S）积累在非传统的PSP载体。
Paralytic shellfish poisoning (PSP), due to saxitoxin and related compounds, typically results from the consumption of filter-feeding molluscan shellfish that concentrate toxins from marine dinoflagellates. In addition to these microalgal sources, saxitoxin and related compounds, referred to in this review as STXs, are also produced in freshwater cyanobacteria and have been associated with calcareous red macroalgae. STXs are transferred and bioaccumulate throughout aquatic food webs, and can be vectored to terrestrial biota, including humans. Fisheries closures and human intoxications due to STXs have been documented in several non-traditional (i.e. non-filter-feeding) vectors. These include, but are not limited to, marine gastropods, both carnivorous and grazing, crustacea, and fish that acquire STXs through toxin transfer. Often due to spatial, temporal, or a species disconnection from the primary source of STXs (bloom forming dinoflagellates), monitoring and management of such non-traditional PSP vectors has been challenging. A brief literature review is provided for filter feeding (traditional) and non-filter feeding (non-traditional) vectors of STXs with specific reference to human effects. We include several case studies pertaining to management actions to prevent PSP, as well as food poisoning incidents from STX(s) accumulation in non-traditional PSP vectors.
