The CropLife International Detection Methods Database

Background

Genetically modified (GM) crops were first introduced in 1994 and have now been adopted by farmers in more than 70 countries (ISAAA Brief 54). As a result, grain trade of GM crops continues to increase, and harmonization of detection methods is important to ensure consistent testing and efficient global trade.

Regions or countries have frequently adopted different approaches for the detection of GM crops and their products. These discrepancies can lead to variations in analytical results and even differing results between laboratories which could contribute to trade disruptions. GM traits in the marketplace are increasingly complex and require specialized and accurate detection methods. CropLife International and its members remain committed to supporting global trade by sharing industry-developed detection methods compliant with standardized guidelines. Harmonizing on these detection methods provides a path to the global harmonization of testing for GM crops and the reduction of the potential for trade disruptions.

The Database

CropLife International members have made these detection methods and related materials available in this online and searchable database.  It comprises full descriptions of validated DNA methods based on PCR, and lists providers for protein-based detection methods for GM crops produced by CropLife members.

It is updated frequently and includes detection methods for commercialized GM crops developed by the four major private plant biotechnology developers (BASF, Bayer, Corteva, and Syngenta). Methods may be licensed freely by governments for regulatory purposes and for the detection of low levels of these GM crops.
