No, it's not a poorly-named SUV from America's struggling car maker, it's cancer!

The first animal feeding trial studying the lifetime effects of exposure to Roundup tolerant GM maize, and Roundup, the world's best-selling weedkiller, shows that levels currently considered safe can cause tumors and multiple organ damage and lead to premature death in laboratory rats, according to research published online today by the scientific journal Food and Chemical Toxicology.

Researchers found that rats fed on a diet containing NK603 Roundup tolerant GM maize, or given water containing Roundup at levels permitted in drinking water and GM crops in the US, died earlier than rats fed on a standard diet. They suffered mammary tumors and severe liver and kidney damage.
