DNA barcoding reveals mislabeling and commercial fraud in the marketing of fillets of the genus Brachyplatystoma Bleeker, 1862, the Amazonian freshwater catfishes economically important in Brazil

The substitution and mislabeling is facilitated by the processing of fish products. We employed a DNA barcoding to authenticate fillets labeled as “dourada” (Brachyplatystoma rousseauxii), and “piramutaba” (Brachyplatystoma vaillantii) marketed in the Brazil. A 615 bp of the Cytochrome oxidase subun...

description The substitution and mislabeling is facilitated by the processing of fish products. We employed a DNA barcoding to authenticate fillets labeled as “dourada” (Brachyplatystoma rousseauxii), and “piramutaba” (Brachyplatystoma vaillantii) marketed in the Brazil. A 615 bp of the Cytochrome oxidase subunit I (COI) was sequenced from 305 fillets and subsequently identified to species level by querying public databases and sequences of reference species. The results revealed a global mean substitution rate of 17%. The highest substitution rate was detected in “dourada” (26%), the most valuable species, followed by “piramutaba” (9%). The most cases of substitutions were by species of lower commercial value, suggesting fraud aimed at increased profits. Therefore, we suggest the improvement of food-labeling regulation, continued inspection, as well as the adoption of the DNA barcode for the molecular authentication of processed fish to prevent substitution of these products in Brazil.
