“…DNA barcodes have been used to identify fish species in numerous products made from different species, such as tuna (Terol et al, 2002), cod (Espineira et al, 2008), anchovy (Jérôme et al, 2008) and shark (Barbuto et al, 2010). Filonzi et al (2010) have used DNA barcode for COI and cytb genes in some catfish products and showed that 32% of these fish products were mislabeled, including 26% of errors with closely related species.…”

“…In fact, hazards such as allergenic proteins and scombrotoxin formation are associated with some species but not others, presenting potential food safety risks if the food is not accurately labeled (http://www.foodsafetynews.com/2012/12/seafoodfraud-public-health-threat-or-economic-trick). It has been reported that seafood products were abundantly mislabeled in the world (Carvalho et al, 2010;Filonzi et al, 2010;Barbuto et al, 2010) but this occurrence of seafood mislabeling has not been studied in Viet Nam to our knowledge.…”

Nucleotide sequences of the Cytochrome oxidase subunit I gene and Cytochrome b were analyzed for Ö10 processed fish products collected from supermarkets in Hanoi, Viet Nam. The similarity between our results and published data from the NCBI and BOLD was compared to identify species. This molecular analysis showed that the common names of only 4 of these products matched with their corresponding scientific names. The other six were mislabeled with an important mislabeling from P. hypophthalmus into P. boucourti. Although no commercial frauds were found in these mislabelled products, the correct scientific names of fish species should be labelled for the processed products as they are in supermarkets.

“…A lack of appropriate labeling of seafood products is observed worldwide and threatens the society and ecological segments (Barbuto et al 2010;Jacquet and Pauly 2008;Lamendin et al 2015). Fish names are commonly replaced or adulterated by the fisheries and food industries, and people are often not capable of distinguishing between taxa because the meat is sliced and packaged prior to sale (Barbuto et al 2010;Lamendin et al 2015).…”

“…Consumers are often unaware that cação refers to shark and ray meat. This mislabeling may preclude people from taking health-and/or conservationrelated decisions concerning the consumption of elasmobranch meat and thus interfere with efforts to reduce consumption or redirect consumption towards non-threatened species (Barbuto et al 2010;Bornatowski et al 2013;Jacquet and Pauly 2008).…”

In Brazil, the demand for sustainably certified seafood is increasing and retailers have promised to source all seafood from sustainable sources by 2015. In the southern portion of the country, elasmobranch meat is sold as cação, and consumers are often unaware that cação refers to any type of elasmobranch. The present study used questionnaires to investigate the lay public’s knowledge of elasmobranch meat sold in a Brazilian city. Shoppers were surveyed at supermarkets in Curitiba, the largest city in southern Brazil. The study revealed that people do not link commercialized cação meat to sharks and rays (Elasmobranchii), with more than half of respondents who claimed to have already eaten cação did not think they had ever eaten shark or ray. The educational profile of interviewees suggests that this lack of knowledge may be even more common in other segments of Brazilian society. Therefore, we suggest that ecological information about elasmobranchs should be included in Brazilian elementary and high school curricula. Such a measure has the potential to modify behavior, create awareness, and stimulate responsibility throughout society, with the primary goal of reducing shark meat consumption and, ultimately, guaranteeing the long term conservation of marine resources.

“…The traditional method of morphology-based species identification fails in some of food adulterationassociated cases. DNA barcoding is widely used in food traceability analysis, e.g., for fish products (Filonzi et al, 2010), shark seafood (Barbuto et al, 2010), Amazonian fishes (Ardura et al, 2010), natural health products (Wallace et al, 2012), and olive oil (Kumar et al, 2011). Thus, this study reports another instance of the use of DNA barcoding in food traceability and shows that DNA barcoding is still a powerful tool to distinguish the species status of raw food materials, even for highly processed food like jerky.…”
