AI Technical Summary

Technical Problem

Current methods for ensuring the geographical origin and quality of farm animals are inadequate, as they rely on audits that can be forged and do not effectively monitor environmental parameters.

Method used

A method using DNA methylation profiling to identify the geographical origin of organisms by comparing test methylation profiles with predetermined reference profiles specific to distinct geographical origins.

Benefits of technology

This method provides a tamper-proof means of identifying the geographical origin of farm animals, ensuring quality control, and evaluating environmental parameters, thereby enhancing traceability and consumer trust.

Abstract

The present invention relates to a method for identifying the geographic origin of an individual test subject or a group of individual test subjects, comprising the step of comparing a test methylation profile obtained from the genomic material of the individual test subject or a group of individual test subjects with one or more predetermined reference methylation profiles, each specific for a distinct geographic origin.
