A new study just came out that seems relevant: Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize
From a press release:
The study involving 100 female rats and 100 male rats were split into groups and fed different amounts of either Roundup-resistant corn, Roundup herbicide or both, over two years. There was also a control group, which was fed regular corn a
nd plain water.
Up to 50 per cent of males fed GM corn or Roundup and 70 per cent of females died prematurely, compared with only 30 per cent and 20 per cent in the control group, the study found. And overall, rats fed GM corn or Roundup developed two to three times more tumours.
This looks as though Monstanto’s GMO corn could be very dangerous, but I’m not really qualified to judge the study—for example, what if the strain of rats is unusually vulnerable?
Edited to add: Yeah, tumor-prone rats, and since the 200 rats were divided into 10 groups, small sample sizes. Still, the effects were pretty large.
Thanks for posting the link to Orac. I didn’t know he was still posting regularly there. I’m excited to read his dissection of the study when I have some spare time.

Thank you very much!

Orac: The study is nonsensical.
Would other people here care to take a look at that study?
Also, I’m still concerned that lifespan (or even multigenerational) studies are so rare.
