Thought this was worth reading so posting a link. It is regarding GM in general.
The thesis of the article that was signed by 300 scientists regarding GM is that anyone that claim that GM is safe is not basing that on adequate testing even though they purport that there has been adequate testing. In the US, the FDA gave GM a "GRAS' rating (Generally Regarded as Safe) even though proper testing has not happened.
Anyhow, here' is the article if anyone is interested:

My own
personal "take" on GM is that the health and fertility problems we're seeing that seem to be related to GM contaminated feeds (for human or animal) may be as much due to the high amount of glyphosate that they can tolerate which is not only "on" the plant but taken up into their structure as well. Those high levels, in addition to chemical fertilizer and pesticides used on GM crops, I think may be enough to be a health hazard...not to mention the terminator genes and other "wonders" of GM...
I guess we shall see.
But I think the main message these scientists are getting at is that we are at risk of having contaminated our soils in such a way that we will have a hard time "healing" the land and IT HAS JUST BEEN A HUGE EXPERIMENT that may go terribly wrong...and
never should have been released into the open until more conclusive testing was done on the long-term effects.
