Result description
DNA-based methods increasingly play a role in food safety control and food corruption detection. A new reference database has been developed which contains 300 high-quality DNA sequences for 42 European commercially important seafood species. These sequences are linked to digital images which can then be used to verify morphological characteristics and relevant metadata. The database is open access, which will enable further research in the area as well as its use as an education tool to train students in DNA barcoding techniques. The database can also be used by the food industry and regulatory agencies to ensure reliable identification of fish species in processed seafood, supporting better transparency in seafood authentication
This output comprises the reference database of high-quality expertly verified DNA sequences of fish species, for which digital pictures are available to verify morphological characters. Sequences are linked to all relevant metadata, including storage of tissue and DNA extracts, origin of the specimens, lab protocols, and digital pictures. This provides reference sequences with 100% reliable species names attached, which is essential for accurate identification of processed food samples. Database contents were validated using phylogenetic inference, to identify similarities between sequences from the same species, collected by different partners. In addition, the applicability of the sequences for DNA barcoding was justified via barcode gap analysis, which showed a clear distinction of genetic distances within and between species.
Addressing target audiences and expressing needs
- To raise awareness and possibly influence policy
- Help in technical expertise
To inform environmental managers and governmental research bodies that monitor seafood authenticity and to share this resource with researchers and educators in the field.
- International Organisations (ex. OECD, FAO, UN, etc.)
- Research and Technology Organisations
- Academia/ Universities
R&D, Technology and Innovation aspects
The database is accessible from the SEAFOODTOMORROW project website and can be indefinitely updated with new specimens and DNA sequences
