Each year, food fraud is estimated at more than US $50 billion. Customers are cheated, reputable producers lose sales and reputations, and dishonest traders are rewarded. Maintaining confidence and trust in the food supply is therefore a high priority for both food producers and consumers. Isotopes can help provide the verification missing in existing paper-trail certification processes. Isotope ratios, though subtle, vary according to where, how and under what environmental conditions a food was produced. They therefore provide a hidden natural signature within the food itself, which enable food regulators to verify whether or not the food in the package has been adulterated or has come from the place claimed on the label.
