A total of 34 fish were obtained from local fishermen, including 30 T. lepturus and four S. cavalla. The fish were necropsied and their internal organs were examined to identify parasites. Prevalence, abundance, and mean intensity of parasitic infections were calculated. In T. lepturus, the most prevalent (20%) nematode was Contracaecum sp., predominantly found in the coelomic cavity. In S. cavalla, the most frequently observed one (100% prevalence) was Hysterothylacium sp., with infections disseminated in the stomach, intestine, liver, and coelomic cavity. All identified parasites were documented for the first time in fish collected from this estuarine complex, CELMM, in Brazil, expanding their known geographical and ecological distribution. The presence of zoonotic parasites in commercially sold fish from CELMM poses a significant public health risk. Therefore, stringent sanitary inspection measures and public awareness initiatives are essential to mitigate contamination risks and ensure the quality of fish products intended for human consumption.<\/jats:p>","DOI":"10.1590\/s1984-29612026034","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T11:01:16Z","timestamp":1785754876000},"source":"Crossref","is-referenced-by-count":0,"title":["Occurrence of zoonotic parasites in economically important fish species from the Northeastern region of Brazil"],"prefix":"10.1590","volume":"35","author":[{"given":"Noemi de Castro","family":"Torres","sequence":"first","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brenda Madruga","family":"Rosa","sequence":"additional","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-1087-2234","authenticated-orcid":false,"given":"Sarah Leticia Paiva","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruna Mesquita de","family":"Moraes","sequence":"additional","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beatriz Menezes","family":"Lins","sequence":"additional","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodney Kozlowiski de","family":"Azevedo","sequence":"additional","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanessa Doro","family":"Abdallah","sequence":"additional","affiliation":[{"name":"Universidade Federal de Alagoas,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2026]]},"reference":[{"issue":"2","key":"ref1","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1590\/1519-6984.190350","article-title":"Nematodas Anisakidae Skrjabin & Karokhin, 1945 and Raphidascarididae Hartwich, 1954 nematodes in Lutjanidae (Pisces: Perciformes) from the Brazilian Northeast Coast","volume":"80","author":"Alves AM","year":"2020","journal-title":"Braz J Biol"},{"key":"ref2","series-title":"Mangroves: ecology, biodiversity and management.","first-page":"63","volume-title":"Mangroves as feeding and breeding grounds.","author":"Arceo-Carranza D","year":"2021"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"298","DOI":"10.1016\/j.tifs.2019.02.013","article-title":"Human health, legislative, and socioeconomic issues caused by the fish-borne zoonotic parasite Anisakis: challenges in risk assessment","volume":"86","author":"Bao M","year":"2019","journal-title":"Trends Food Sci Technol"},{"issue":"2","key":"ref4","doi-asserted-by":"crossref","first-page":"83","DOI":"10.5007\/2175-7925.2008v21n2p83","article-title":"H\u00e1bito alimentar do peixe-espada adulto, Trichiurus lepturus, na costa norte do Rio de Janeiro, sudeste do Brasil","volume":"21","author":"Bittar VT","year":"2008","journal-title":"Biotemas"},{"issue":"7","key":"ref5","doi-asserted-by":"crossref","DOI":"10.1371\/journal.pone.0040447","article-title":"Morphological and molecular diagnosis of anisakid nematode larvae from cutlassfish (Trichiurus lepturus) off the coast of Rio de Janeiro, Brazil","volume":"7","author":"Borges JN","year":"2012","journal-title":"PLoS One"},{"key":"ref6","article-title":"Lei no. 8.080, September 19, 1990.
