Could do better! A high school market survey of fish labelling in Sydney, Australia, using DNA barcodes.

ABSTRACT:

Background

Processed seafood products are not readily identifiable based on physical characteristics, which leaves the industry vulnerable to high levels of product mislabelling (globally estimated at 5-30% mislabelled). This is both a food safety issue and a consumer protection issue as cheaper species could be substituted for more expensive species. DNA barcoding is proving to be a valuable tool for authentication of fish products. We worked with high school students to perform a market survey and subsequent species assessment via DNA barcoding to investigate the accuracy of fish product names used by retailers in Sydney, Australia.

Methods

Sixty-eight fish samples, sold under 50 different common names, were purchased anonymously from two retailers in Sydney. Each product
