What are we not supposed to know about ?

As far as I know that wouldn't happen in the first place. Given proper regulation of course.
Doesn't mean certain environmentalist groups won't claim it anyway.

There was also a report in Nature that Bt maize was contaminating maize in Mexico, its center of origin.[41] Nature later "concluded that the evidence available is not sufficient to justify the publication of the original paper."[42] A subsequent large-scale study, in 2005, failed to find any evidence of contamination in Oaxaca.[43] However, further researchs confirmed initial findings concerning contamination of natural maize by transgenic maize [44].

There is also a risk that for example, transgenic maize will crossbreed with wild grass variants, and that the Bt-gene will end up in a natural environment, retaining its toxicity. An event like this would have ecological implications, as well as increasing the risk of Bt resistance arising in the general herbivore population. However, there is no evidence of crossbreeding between maize and wild grasses.

In 2009 it was reported that 82,000 hectares (200,000 acres) of Bt corn in South Africa failed to produce seeds. Monsanto offered compensation and claims that the corn varieties affected were "insufficiently fertilised in the laboratory". Marian Mayet an environmental activitist and director of the Africa-centre for biosecurity in Johannesburg called for a government investigation and asserts that the biotechnology is at fault, "You cannot make a 'mistake' with three different varieties of corn".[45]

As of 2007, a new phenomenon called Colony Collapse Disorder (CCD) is affecting bee hives all over North America, and elsewhere. Initial speculation on possible causes ranged from cell phone and pesticide use[46] to the use of Bt resistant transgenic crops.[47] The Mid-Atlantic Apiculture Research and Extension Consortium published a report on 2007-03-27 that found no evidence that pollen from Bt crops is adversely affecting bees. Several researchers in the US have since attributed CCD to a new virus, unrelated to Bt crops.[48]. The controversy, however, is not closed yet.
