About GMO Testing
The Non-GMO Project Standard allows for a combination of testing methods, with a focus on quantitative PCR analysis by ISO 17025 accredited laboratories. Testing is required on all inputs at risk for GMO contamination (as defined in Appendix B of the Standard), and is not required on finished products (testing finished products is generally unreliable and impractical).
It is the goal of the Project to assess compliance with our action thresholds for GMO contamination as efficiently and inexpensively as possible. To that end, our technical consultants (FoodChain Global Advisors) work with Participants to determine where the best place in the supply chain for testing is; usually this is as close to initial processing as possible. In this way, and in combination with the traceability and segregation requirements of the Non-GMO Project Standard, it is possible for one test to cover large quantities of material. With adequate traceability and segregation practices, testing is only required at ONE place in the production chain, and is supported by appropriate spot test monitoring.
