When it comes to animal products, consumers – more than in other food categories – prefer local, regional or at least national products over others for reasons such as locality-related quality or environmental factors such as sustainability. Some regions in the world might also be connected to negative values such as poor animal welfare conditions or mix-up allegations in big slaughterhouses.
There are comprehensive labelling requirements for meat, fish and eggs with a number of quality labels and seals. But how can someone be sure to really get what they intend to buy? How can one be sure, that they don´t indirectly support the the deterioration of the marine ecosystems by buying fish from illegal, unreported, and unregulated (IUU) fishing? How is it possible to establish and maintain consumer trust when manipulation can be very diverse and goes beyond false information about the origin of a product?
Isotope ratio mass spectrometry (IRMS) can help answer questions about the geographic origin and authenticity of your animal products at all points of the supply chain.
By determining and interpreting the stable isotope ratios of carbon, nitrogen, sulfur, hydrogen and oxygen of any animal product, the so-called isotope fingerprint (consisting of all five ratios) is established which is characteristic for the sample and can be compared to reference data from reference samples from different regions or to a data base.
To achieve high geographical resolution and credible results, we use our global database, as well as our expertise and know-how to provide advanced customized origin testing by including more parameters. We can also source reference samples from specific regions worldwide on demand to provide analytical testing evidence for product claims or questions such as suspected (not declared) origin, feeding scheme, organic/conventional etc.
