A vast variety of soy GM events has entered the market, and analytical testing approaches need to be updated to cover these. It is important to keep in mind that cultivation status of GMOs is subjected to the respective national regulatory framework.

The main reason is that common generic markers used for detection of previous varieties, e.g. the CaMV 35S-Promoter and NOS-Terminator, are not present in many of the new and future varieties. As a result, no exclusive testing regime exists any longer, since a multitude of different solutions are equally valid.

For actors in the supply chain it is becoming increasingly difficult to assess whether a GMO test is really sufficient and therefore rely on a competent laboratory partner more than ever.
