That is completely unknown. See the trans fat debacle for a reminder of the vast realm of ignorance and void of information in that respect. It is also flagrantly premature - even if it were known, no assurance of safety could be derived from the fact. And it deals with only a small aspect of the dangers of GM deployment as currently accomplished and further proposed. Your links will do. Just look at the time line: Pioneer had the stuff in production - ready to market, fully developed after years of effort and large expenditure - before they contracted that basic, introductory, preliminary safety check. They had to recall and destroy quite a bit of product (and lost some of it to various markets, IIRC). We know the FDA didn't require it, because the product was not human food. We know Pioneer did not think it up themselves, because they would have done so prior to making such a large investment. If I can find the account from the guy who did notice the danger, which I read years ago ( I can't remember his name - IIRC he was on vacation in Brazil at the time), I will link it, but meanwhile the physical situation is pretty clear. On the contrary, a very easy task. Even the US authorities have been very lax and easily co-opted, and in many countries (such as the African ones Monsanto is pressuring) simple bribery will do.
