New research proves that co-existence is NOT a problem
Brussels, 1 December 2004:
Co-existence of GM and non GM maize crops can be successfully delivered by applying a few simple measures according to a report published today.

The report "Genetically Modified Maize - Pollen Movement and Crop Co-existence" was published just as the European Commission failed to come to a decision on whether national bans on a number of authorised GMOs currently in place in five EU member states should be lifted, and as a number of member states have put forward their rules for co-existence.
According to one of the authors of the report[1], Graham Brookes:

‘The evidence is clear cut and consistent – all you need for co-existence of GM and non GM maize is four buffer rows or several metres separation distance between crops.  This contrasts with impractical and disproportionate maize co-existence rules being put forward in some member states’    

The report reviewed the commercial experience of farmers who grow GM maize in Spain and summarised the findings of a number of co-existence research studies in Europe and other countries.

Key findings:

>   GM-specific co-existence research in Spain and France shows that by applying good farming practices and normal harvesting practices alone (i.e. without the formal application of co-existence measures) the 99.1% purity threshold set by the 2004 EU labelling legislation can be achieved.

>   By applying additional specific co-existence measures in isolation or in combination the probability of GM adventitious presence being found in a non GM maize crop (grown in close proximity) is reduced further. 

>   Experience from Spain shows that the application of four buffer rows of non GM maize between a GM crop (on the GM growing farm) and a non GM crop (on an adjacent farm in plots of under 1 hectare) as a single measure has delivered effective co-existence. 

>   A separation distance of 6 metres is also effective.  Application of a greater separation distance (e.g. 10-12 metres identified in the French co-existence research) offers additional provision for worst case scenarios and reduces further the probability of GM adventitious presence occurring to minute levels.
