A Code of Practice on the declaration and labelling of fish content in fish product has been written with respect to the relevant legislation. The Code contains interim nitrogen factors for fish ingredients (used to determine fish content) that do not account for variables during processing. Accurate up-to-date nitrogen factors are crucial for the calculation of the fish content of fish products. <p>A collaborative study to determine the composition of certain commercially important fish species is required so that both the trade and enforcement side can have confidence in fish content declarations made on fish products. This can support official food enforcement, particularly with respect to correct labelling.
The study will centre on Atlantic cod. Key steps to meet the objective of the project include:
Prepare sampling and analysis protocols.
<li>Arrange sampling at frozen block production units in the UK (using fish from the UK and five countries which export to the UK)
<li>Distribute samples to five participating laboratories for chemical analysis of composition. The importance of this work demands that all analytical methods used are recognised and validated, and that sample analysis is assigned to experienced analysts.
<li>Carry out a statistical analysis of the results after each sampling phase to ensure statistical validity and carry out repeat analysis if necessary.
<li>At the end of sampling and analysis, carry out final statistical analysis so that recommendations for updating fish nitrogen factors can be made.</ul>
