Abstract: An isotopic identification method is provide that makes it possible, where appropriate, to link a livestock animal or animal product to a specific farm, or a plant or a plant product to a farm, by analyzing the concentration of ratios or stable isotopes, and comparing with isotopic codes previously generated in a unique fashion for a set of frames. A method is also provided that makes it possible to impose a unique code on the animals of a farm or on the plants of a farm, and a computer making it possible to store the unique codes generated in memory is provided to generate unique codes for new farms and to perform comparisons.

The invention also relates to a method which makes it possible to impose a unique code on the animals of a farm or on the plants of a farm, a computer making it possible to store the unique codes generated in memory, to generate unique codes for new farms and to perform comparisons.

Abstract: Method for isotopic identification, allowing, where appropriate, a liquid to be linked to a site of growth or harvest or a sub-product derived from a determined liquid, via analysis of concentration or of ratios of stable isotopes, and comparison to isotopic codes generated beforehand in a manner unique to a set of liquids issued from a site of growth, harvest or conversion. The invention also relates to a method that makes it possible to give a unique code to liquids of a site of growth, harvest or conversion, and to a computer making it possible to store the unique codes generated in memory, to generate unique codes for new liquids of a site of growth, harvest or conversion and to perform comparisons.
