Cancer of Corruption, Seeds of Destruction: The Monsanto GMO Whitewash

In September 2012, Food and Chemical Toxicology, a serious international scientific journal, released a study by a team of scientists at France's Caen University led by Professor Gilles-Eric Seralini. Before publication the Seralini study had been reviewed over a four-month period by a qualified group of scientific peers for its methodology and was deemed publishable.

It was no amateur undertaking. The scientists at Caen made carefully-documented results of tests on a group of 200 rats over a two-year life span, basically with one group of non-GMO fed rats, a so-called control group, and the other a group of GMO-fed rats.

Significantly, following a long but finally successful legal battle to force Monsanto to release the details of its own study of the safety of its own NK603 maize (corn), Seralini and colleagues reproduced a 2004 Monsanto study published in the same journal and used by the European Food Safety Authority (EFSA) for its 2009 positive evaluation of NK603.

Seralini's group based their experiment on the same protocol as the Monsanto study but, critically, were testing more parameters more frequently. And the rats were studied for much longer-their full two year average life-time instead of just 90 days in the Monsanto study. The long time span proved critical. The first tumors only appeared 4 to7 months into the study. In industry's earlier 90-day study on the same GMO maize Monsanto NK603, signs of toxicity were seen but were dismissed as "not biologically meaningful" by industry and EFSA alike. It seems they were indeed very biologically meaningful.

The study was also done with the highest number of rats ever measured in a standard GMO diet study. They tested also "for the first time 3 doses (rather than two in the usual 90 day long protocols) of the Roundup-tolerant NK603 GMO maize alone, the GMO maize treated with Roundup, and Roundup alone at very low environmentally relevant doses starting below the range of levels permitted by regulatory authorities in drinking water and in GM feed."

Their findings were more than alarming. The Seralini study concluded, "In females, all treated groups died 2-3 times more than controls, and more rapidly. This difference was visible in 3 male groups fed GMOs Females developed large mammary tumors almost always more often than and before controls; the pituitary was the second most disabled organ; the sex hormonal balance was modified by GMO and Roundup treatments. In treated males, liver congestions and necrosis were 2.5-5.5 times higher. This pathology was confirmed by optic and transmission electron microscopy. Marked and severe kidney nephropathies were also generally 1.3-2.3 greater. Males presented 4 times more large palpable tumors than controls "
