The differences worldwide in the regulatory
regimes for GM crops have resulted inasynchronicity in approvals of new crops.
Because agriculture is an open process, the
presence of unauthorized GM material cannot
be excluded in traded commodities. If the
importing country operates a ‘zero tolerance’
policy, imports may be rejected if they contain
traces of unauthorized GMOs43. A global discussion
on the governance of these new techniques
seems necessary in the light of previous
experiences with current biotech-derived crops
and trade disruptions.
