I'll try to be quick. I spoke at a conference in Melbourne, Australia, last year. About 300 people were there and probably 200 scientists from all over Europe. The main part was commingling and how to grow biotech crops alongside other crops, and there are tons of studies. I wish I had some of the numbers; I'm just going off the top of my head, so forgive me, but with a 0.9% low-level presence, they were unable to cross-pollinate open- or closed-pollinated crops, even when they are grown together in the same field.
Their analysis--and this was by three or four different people from different countries--was that at the farm gate, and that's all I can speak to, the risk of cross-contamination was essentially zero because you cannot get the crops to contaminate each other. That was a resounding thing I took from that conference. By no means was that conference for genetically modified...that's what the conference was about. Scientists came from all over Europe, and I found it really interesting to see that they could not get to the levels that needed...if there is zero percent commingling, or it's low-level presence, I don't think anybody can expect that, because with our testing we can get to the billionth and trillionth, so at 0.9% it was impossible at the farm gate.
