Environmental groups sharply criticised the EU Commission for opening the door to further GMO cultivation in Europe.
"Instead of banning this toxic maize (corn) and protecting both consumers and the environment, the European Commission has buckled once again to industry pressure," said Mute Schimpf of Friends of the Earth Europe.
It said the GMO corn was highly toxic and would harm the delicate habitat of butterflies and moths.
DuPont Pioneer, however, insists that its 1507 corn is grown throughout the world and had received no less that 7 positive safety reports from the EU.
The EU has strict guidelines on authorising and informing consumers about foods containing GMOs a policy that has caused problems for producers of genetically modified seeds such as the US-based Monsanto, which are used to less stringent rules around the world.
At the moment, Monsanto's MON 810 corn is the only GMO farm product cultivated in the EU, and even then, it only represents 1.35 percent of the EU's corn cultivation.
That contrasts sharply with the widespread use of GMOs in North and South America.
The European Commission also proposed to change the way that GMOs could be introduced in Europe, allowing individual member states to reject their cultivation based on a series of social or political grounds even if it has been approved throughout the EU on a scientific basis.
