Fish are also a crucial part of a healthy, balanced diet. However, the consumption of these products may cause food poisoning through marine biotoxins. In recent years, several legal acts have been published by the European Commission to regulate toxin limits and describe their reference analysis methods. Commission Regulation (EC) No. 853\/2004 established the maximum contents of marine biotoxins only in bivalve mollusks. Although other groups of marine organisms such as crustaceans (crabs, shrimps, and lobsters) and fish are not included in the EU rules for toxin monitoring, they may still be vectors of marine biotoxins for humans. Due to this, there is an urgent need for studies regarding the occurrence of marine biotoxins in non-bivalve seafood organisms and their potential influence on public health. In this review, the most important cases of accumulation of marine biotoxins in crustaceans and fish in recent years are described.<\/jats:p>","DOI":"10.3390\/toxins17120589","type":"journal-article","created":{"date-parts":[[2025,12,9]],"date-time":"2025-12-09T16:53:33Z","timestamp":1765299213000},"page":"589","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Marine Biotoxins in Crustaceans and Fish\u2014A Review"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7848-9024","authenticated-orcid":false,"given":"Anna","family":"Madejska","sequence":"first","affiliation":[{"name":"Department of Microbiology of Food and Feed, National Veterinary Research Institute, Partyzant\u00f3w 57, 24-100 Pu\u0142awy, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2295-8837","authenticated-orcid":false,"given":"Jacek","family":"Osek","sequence":"additional","affiliation":[{"name":"Department of Microbiology of Food and Feed, National Veterinary Research Institute, Partyzant\u00f3w 57, 24-100 Pu\u0142awy, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Paz, O., and Marisa, S.
