“…However, the consumption of raw or inadequately cooked fish remains a significant risk factor. Concerns related to the consumption of mislabeled seafood are linked to allergies, contaminants such as mercury and other heavy metals and toxins [ 21 ]. Among these, tetrodotoxin and ciguatoxin are the most frequent and they may cause paralysis and potentially death if ingested in excessive quantities [ 22 ].…”

Fisheries products are some of the most traded commodities world-wide and the potential for fraud is a serious concern. Fish fraud represents a threat to human health and poses serious concerns due to the consumption of toxins, highly allergenic species, contaminates or zoonotic parasites, which may be present in substituted fish. The substitution of more expensive fish by cheaper species, with similar morphological characteristics but different origins, reflects the need for greater transparency and traceability upon which which the security of the entire seafood value-chain depends. Even though EU regulations have made significant progress in consumer information by stringent labelling requirements, fraud is still widespread. Many molecular techniques such as DNA barcoding provide valuable support to enhance the Common Fisheries Policy (CFP) in the protection of consumer interests by unequivocally detecting any kind of fraud. This paper aims to highlight both the engagement of EU fishery policy and the opportunity offered by new biotechnology instruments to mitigate the growing fraud in the globalized fish market and to enforce the food security system to protect consumers’ health. In this paper, after a presentation of EU rules on fish labeling and a general overview on the current state of the global fish market, we discuss the public health implications and the opportunities offered by several techniques based on genetics, reporting a case study to show the efficacy of the DNA barcoding methodology in assessing fish traceability and identification, comparing different species of the Epinephelus genus, Mottled Grouper (Mycteroperca rubra) and Wreckfish (Polyprion americanus), often improperly sold with the commercial name of “grouper”.

“…Further, Mull et al [81] observed that high contamination levels in sharks are directly connected with geographical areas that contained high levels of pollutants. Therefore, the use of such ambiguous labels with species information completely missing in markets and fishmongers greatly hampers consumers from exercising their right to avoid species associated with specific health issues [82][83][84].…”

Given that the global shark meat market is poised to grow in future years, the aim of this study was to use DNA sequencing of the cytochrome c oxidase I (COI) and NADH dehydrogenase subunit 2 (NADH2) mitochondrial genes to examine the market of shark meat products in Italy. This made it possible to analyze patterns of species utilization and commercialization of threatened, endangered and/or prohibited species, focusing on fraudulent activities in the shark food chain in order to propose seafood safety and environmental sustainability solutions. The study shows that the labeling of shark meat products generally lacks comprehensive information, thus making it difficult for consumers to make informed purchasing decisions and fails to comply with European Union (EU) legislation regarding seafood labelling. Molecular investigation reveals a high mislabeling rate (45.4%), highlighting widespread use of cheaper species either in order to replace species that are better known and more popular, or else in order to sell various threatened species. Considering that seafood mislabeling can circumvent the management of sustainable fisheries and facilitate Illegal, Unreported and Unregulated (IUU) fishing, the routine use of genetic analysis should be encouraged among control and enforcement agencies in order to implement effective management measures. This would help to build a species-specific reporting system for all catches, and enhance control measures, in order to prevent illegal activities connected with shark catches and trade around the world.

“…Um grande conjunto de parasitos tem ainda importância na medicina humana, pois são agentes etiológicos de zoonoses (doenças transmitidas às pessoas pelos animais), sendo as mais importantes a anisakíase e a difilobotriose (PAVANELLI et al, 2015). Sendo assim, uma ampla gama de aspectos sobre o parasitismo em peixes pode ser explorada, entre eles a riqueza e diversidade taxonômica (LUQUE e POULIN, 2007), o impacto econômico (TAVARES-DIAS e MARTINS, 2017), na saúde humana (WILLIAMS et al, 2020; BUCHMANN e MEHRDANA, 2016) e a ecologia do parasitismo (POULIN, 2011).…”

Conhecimento Ictioparasitológico Tradicional Dos Pescadores Artesanais Do Rio Jaguaripe, Bahia, Nordeste Do Brasil

A etnoparasitologia é uma área de estudo que relaciona-se diretamente com a etnoecologia uma vez que, por definição, o parasitismo é considerado uma das relações simbióticas entre seres vivos. A ictioparasitologia pode ser estudada sob este prisma, avaliando-se o modo como as populações ribeirinhas compreendem as doenças parasitárias dos animais dos quais dependem para sua subsistência. Esta pesquisa objetivou analisar o conhecimento tradicional de pescadores dos municípios de Nazaré e Jaguaripe, Bahia, que realizam pesca no Rio Jaguaripe, sobre as interações peixes-parasitos, visando observar a percepção da ocorrência de parasitos, da influência desses organismos sobre os peixes, da dinâmica do parasitismo (sazonalidade, ciclo de vida) e da relação dos parasitos de peixes com o ser humano e com possíveis zoonoses. A seleção dos pescadores deu-se por amostragem tipo bola de neve e a coleta de dados por meio de questionário aberto e semiestruturado. Foram entrevistados 27 pescadores sendo os dados analisados qualitativamente e quantitativamente. Os resultados obtidos de ambas as comunidades apontam para um conhecimento de pelo menos dois grupos zoológicos de parasitos: Crustacea e Nematoda. Indicam reconhecimento de aspectos como sazonalidade, patologias e biologia parasitária. Também demonstrou que os pescadores percebem parasitos principalmente daqueles peixes de interesse comercial e não consideram a possibilidade de parasitos de peixes causarem doenças em humanos.
