Growing authorised GMOs, doing research on co-existence, and deciding on co-existence regulations actually function well in parallel. Because safety concerns are already addressed at the approval level, it is not considered dangerous to learn about co-existence and traceability as we go. Regulations on co-existence have been in flux ever since GMOs entered the market. They adapt to reflect shifts in demands from citizens and the ever-increasing complexity of GMO dynamics worldwide. The latest legislation on GM plants in the EU, with a new, process oriented labelling basis, came into effect only in 2003. When these regulations were implemented, the science required to realise them lagged behind. Co-Extra is doing the research needed to secure a process-based labelling system and freedom of choice according to recently implemented GMO regulations.
