Abstract
Mislabelling of seafood products has been documented in numerous countries for over three-quarters of
a century. With a trend towards increased consumption of seafood, the informed consumer demands
accurately labelled products that provide full disclosure of composition. DNA barcoding can be used to
accurately identify a seafood product to species based on its genetic signature, and so provides a means
to test the authenticity and accuracy of seafood labelling. This can be especially useful for products such
as fillets which have few or no unambiguous identifying characters, and can easily be mislabelled. We
investigated labelling accuracy in seafood retailers in Tasmania, Australia. Thirty-eight seafood products
were obtained from seafood retailers, sequenced for the barcoding gene region cytochrome oxidase
subunit 1(CO1), and subsequently identified to species level by querying GenBank and Barcode of Life
Data Systems (BOLD) DNA sequence records. Results were compared with standard fish names (SFN)
prescribed under the Australian Fish Names Standard (AFNS) and FishBase. Of the 38 samples, none were
deemed to have been mislabelled under Australian regulation, although in some cases naming discrepancies
and ambiguity may cause confusion for some consumers. Our work, while reflecting high
standards in Tasmanian seafood, highlights the need for mandatory standard labelling across all seafood
products so as to eliminate any possible misrepresentation.
