Abstract

Paralytic shellfish toxins (PSTs) are potent marine neurotoxins mainly associated with dinoflagellates. European Union (EU) Regulation Nº 853/2004 and its amendments establish the maximum permitted levels for PSTs in bivalve molluscs, echinoderms, tunicates and gastropods. In Europe, the analyses of marine biotoxins for monitoring purposes is mainly focused on bivalve molluscs. Other vectors, including some from the regulated groups, are rarely covered by monitoring programs.

The aim of this study is to estimate the prevalence of PSTs across species from eight marine invertebrate groups and fish in Galicia (NW Spain). In total, 533 invertebrates (echinoderms, gastropods, cnidarians, crustaceans, cephalopods, polychaetes, tunicates, porifera and bivalves) and 96 fish samples were collected between April 2021 and September 2023 and analysed using both LC-FLD and LC-MS/MS methods. PSTs were detected in 265 samples in all groups except cephalopods and tunicates. Quantifiable levels were found in 233 samples.

Our results show the existence of potential PST vectors other than bivalves, including edible organisms of great economic value. These findings could be extrapolated to other countries with similar harmful algae events and stress the need for further surveys on different groups of marine invertebrates for a better public health protection. To our knowledge, this is the first report of PSTs in Littorina spp., Nassarius spp., Patella ulyssiponensis, Balanus spp., Carcinus maenas, Luidia sarsi and Ophiotrix spp. in the EU. Moreover, PSTs are also described for the first time in Nucella spp., Patella spp. and Polybius henslowii from Spain.

评估麻痹性贝类毒素在非传统媒介中的流行程度以及与食用贝类毒素相关的潜在健康风险

麻痹性贝类毒素（PSTs）是一种主要与鞭毛虫有关的强效海洋神经毒素。欧洲联盟（欧盟）规例Nº853/2004及其修订订明双壳类软体动物、棘皮动物、被囊动物及腹足类动物体内PSTs的最高容许含量。在欧洲，用于监测目的的海洋生物毒素分析主要集中在双壳类软体动物上。其他病媒，包括一些来自受监管群体的病媒，很少被监测项目覆盖。本研究的目的是估计加利西亚（西班牙西北部）八个海洋无脊椎动物种群和鱼类中pst的患病率。在2021年4月至2023年9月期间，共收集了533种无脊椎动物（棘皮动物、腹足动物、刺胞动物、甲壳动物、头足动物、多毛类、被囊动物、多孔动物和双壳类）和96种鱼类样本，并使用LC-FLD和LC-MS/MS方法进行了分析。除头足类和被囊类外，其余各组265份样品均检测到PSTs。在233个样本中发现了可量化的水平。我们的研究结果表明，除了双壳类之外，存在潜在的PST载体，包括具有巨大经济价值的可食用生物。这些发现可以外推到其他有类似有害藻类事件的国家，并强调需要对不同的海洋无脊椎动物群体进行进一步调查，以更好地保护公众健康。据我们所知，这是欧盟首次报道Littorina spp、Nassarius spp、Patella ulyssiponensis、Balanus spp、Carcinus maenas、Luidia sarsi和Ophiotrix spp中存在PSTs。此外，在西班牙的Nucella spp.、Patella spp.和Polybius henslowii中也首次发现了pst。

期刊介绍： Food Control is an international journal that provides essential information for those involved in food safety and process control. Food Control covers the below areas that relate to food process control or to food safety of human foods: • Microbial food safety and antimicrobial systems • Mycotoxins • Hazard analysis, HACCP and food safety objectives • Risk assessment, including microbial and chemical hazards • Quality assurance • Good manufacturing practices • Food process systems design and control • Food Packaging technology and materials in contact with foods • Rapid methods of analysis and detection, including sensor technology • Codes of practice, legislation and international harmonization • Consumer issues • Education, training and research needs. The scope of Food Control is comprehensive and includes original research papers, authoritative reviews, short communications, comment articles that report on new developments in food control, and position papers.
