Seafood has been identified as one of the foods vulnerable to mislabelling and fraud. In addition, Singapore has a high consumption of seafood (average 22kg/per capita/year). Researchers at the National University of Singapore conducted a survey to verify the labelling/description of seafood species. Eighty eight samples were collected from retail outlets and restaurants. Using mitochondrial DNA barcoding of the cytochrome c oxidase Subunit-I to identify seafood species, 42 different species were identified. In total, 26% (23) of the samples were mislabelled. The three most frequently mislabelled fish were Anoplopoma fimbria (Sablefish) sold as Black Cod, Dissostichus eleginoides (Patagonian toothfish) sold as Cod or Seabass, and Pangasianodon hypophthalmus (Iridescent shark) sold as Dory or Bocourti. Restaurants did not show any evidence of mislabelling, and all the mislabelled samples came from retail outlets.
