Well first off. This wasn't the first or most comprehensive study on GMOs.... They did 10 year studies on farm animals that showed... zero effect.
Or... how about the fact that you know... tons of animals have been fed this stuff for a long ass time now... and nobodies noticed anything?
Outside which... labrat studies are pretty much the epitome of bunk research.
Lab rat studies also showed Aspartaine causes cancer too....
Which... it doesn't. Shoddy Lab rat cancer studies are why seemingly EVERYTHING causes cancer... and everything fights cancer. Sometimes the same things that fight it, cause it if you've got two intersted groups.
Then you look at the statistical methods....

and the rest of the problems...
More or less explains it though. In a way that's snarkier then i'd like but... it gets the point across.

This one perhaps does it a little better and less snarky.

Edit: Or this... it's rare to see such a scientific beatdown of faulty science. All of the releated French Academia decided to band together.

Six French academic societes are condeming the study as inaccurate.
“This work does not enable any reliable conclusion to be drawn,” they said, adding bluntly that the affair helped “spread fear among the public.” The joint statement—an extremely rare event in French science—was signed by the national academies of agriculture, medicine, pharmacy, sciences, technology and veterinary studies. It was sparked by research published in September that said rats fed with so-called NK603 corn and/or doses of Roundup herbicide developed tumors….
Two fast-track official investigations into the study, ordered by the government, are due to be unveiled on Monday.
The academies’ statement said: “Given the numerous gaps in methods and interpretation, the data presented in this article cannot challenge previous studies which have concluded that NK603 corn is harmless from the health point of view, as are, more generally, genetically modified plants that have been authorised for consumption by animals and humans.” In withering terms, it dismissed the study as “a scientific non-event.” “Hyping the reputation of a scientist or a team is a serious misdemeanour when it helps to spread fear among the public that is not based on any firm conclusion,” the academies said.
