Abstract: Seafood is one of foods most prone to substitution and fraud potentially leading to negative implications on consumer trust and health. Additionally, seafood adulteration might be accompanied by overfishing of particular species. Therefore, the European Union issued several regulations on the declaration of seafood and its control. In support of the implementation of these regulations as well as research on seafood authenticity, the user-friendly database called FISH-FIT has been established. FISH-FIT provides users with valid DNA sequences of authentic tissue samples, a sequence alignment tool and a collection of methods relevant to this field. Furthermore, authentic tissue materials are physically stored for all entries in the database and aliquots can be requested directly via the website. The FISH-FIT resource allows users to compare their samples with verified materials and aids in the development of new DNA-based methods for authentication. Overall, FISH-FIT contributes to the harmonisation of seafood authentication methods in Europe in the long term.
What is FISH-FIT ?
FISH-FIT was created within the framework of SEATRACES, an European Interreg Atlantic Area project: "Smart Traceability and Labeling ToolBox for a Sustainable Seafood Production" to support EU control laboratories and institutions in seafood authenticity testing.
Traceability and labelling of fishery products are important prerequisites to combat illegal fishing, consumer deception and food fraud, which represent a serious risk to the economic development of the marine sector in the North Atlantic region. To uncover mislabelling and seafood fraud, mainly DNA-methods are used by control institutions for reliable species identification.
Who can use FISH-FIT ?
FISH-FIT was established for European control laboratories to facilitate their work in seafood identification.
Please note that currently only public European control institutions can register and access to FISH-FIT. Further opening to other institutions and laboratories may be considered after an initial phase of establishment.
To gain access to FISH-FIT, users need to fill in a registration form and wait for access permission. After successful registration, the content will be visible and authentic material can be requested.
