Lab mice fed Monsanto’s genetically modified corn and water exposed to their herbicide Roundup led to tumors and organ damage, reports a French study that could have resonance in the debate over GMOs.
The peer-reviewed study, the first of its kind to show potential damage from lifetime exposure to GMOs, appeared in the journal Food and Chemical Toxicology.
Gilles-Eric Seralini of the University of Caen and colleagues said rats fed on a diet containing NK603 – a seed variety made tolerant to dousings of Roundup – or given water containing Roundup at levels permitted in the United States died earlier than those on a standard diet.
The animals on the GM diet suffered mammary tumours, as well as severe liver and kidney damage.
The researchers said 50 percent of males and 70 percent of females died prematurely, compared with only 30 percent and 20 percent in the control group.
Monsanto has tried to deflect the study by asserting that his longtime criticism of this researcher reflects a bias. But the study did get a peer review, though some independent scientists have criticized the study for using the wrong kind of rat.
