Truthout: In What is being described as the first ever and most comprehensive study of the effects of genetically modified foods on mammalian health, researchers have linked organ damage with consumption of Monsanto's GM maize. All three varieties of GM corn -- Mon 810, Mon 863 and NK 603 -- were approved for consumption by US, European and several other national food safety authorities...
The data 'clearly underlines adverse impacts on kidneys and liver, the dietary detoxifying organs, as well as different levels of damages to heart, adrenal glands, spleen and haematopoietic system,' reported Gilles-Eric Séralini, a molecular biologist at the University of Caen...
Their December 2009 study appears in the International Journal of Biological Sciences (IJBS). This latest study conforms with a 2007 analysis (.pdf) by CRIIGEN on Mon 863, published in Environmental Contamination and Toxicology, using the same data...
Chronic problems are rarely discovered in 90 days; most often such tests run for up to two years. Tests 'lasting longer than three months give more chances to reveal metabolic, nervous, immune, hormonal or cancer diseases,' wrote Séralini, et al... The researchers conclude that the raw data from all three GMO studies reveal novel pesticide residues will be present in food and feed and may pose grave health risks to those consuming them.
They have called for 'an immediate ban on the import and cultivation of these GMOs and strongly recommend additional long-term (up to two years) and multi-generational animal feeding studies on at least three species to provide true scientifically valid data on the acute and chronic toxic effects of GM crops, feed and foods...
Ecological effects are also in play. Ninety-nine percent of GMO crops either tolerate or produce insecticide. This may be the reason we see bee colony collapse disorder and massive butterfly deaths. If GMOs are wiping out Earth's pollinators, they are far more disastrous than the threat they pose to humans and other mammals.
