Test Description

This proficiency test concerns the correct identification of an unknown fish species from a target list of possible species. Three samples provided of different white fish.

Deliberate food adulteration for economic gain is increasing, with high profile issues making national or international news. There is now a greater emphasis on authenticity testing with a number of international projects addressing the analytical problems. The Fapas authenticity and adulteration proficiency tests allow laboratories to assess their detection capability for undeclared high level substitutions. And provide feedback from which to improve your testing ability if needed, or maintain high quality testing across a range of testing environments.

Fish speciation offers key challenges to testing laboratories. As global fish consumption continues to remain high across a large portion of the globe, the challenge for labs to maintain high quality testing across a range of testing conditions will continue to remain key to both manufacturer and lab business success.

To mitigate the risk of poor quality testing standards Fapas proficiency tests should be employed to highlight any areas of improvement within your testing practises, be this unintentional bias or generally poor laboratory practise. These issues can be highlighted quickly and effectively from which to mitigate any risk of low quality testing standards being passed to your customers.

This proficiency test uses three fish samples from the analyte list to identify each fish species. This can stand you in good stead from which to highlight adulteration or ineffective labelling practises.
