Application of DNA barcoding to detect mislabeling of fish fillet products from Jabodetabek's market

Mislabeling of fish fillet product is one of the key issues in food safety and sustainability. Species identification is an important step of fish fillet traceability and DNA barcoding has been proved as a standard method. Fourty seven 47 fish fillet products were collected from modern and traditional markets in the Jabodetabek area. DNA barcoding was used to analyze the compliance of the product label. This research also highlighted that near threatened (NT), Vulnerable (VU), endangered (EN), and critically endangered (CR) species considered to be facing a high risk of extinction have been used as a substitution in fish fillet product. The application of DNA mini-barcoding gives better resolution in species identification for commercial species. From this research, we found that there are some mislabeled fish fillet products, including blue shark meat that is listed as Near Threatened in IUCN Red List in one of the products.
