Genetically-modified corn causes damage to liver, kidneys, and other organs

A study published in December 2009 in the International Journal of Biological Sciences found that three varieties of Monsanto genetically-modified corn caused damage to the liver, kidneys, and other organs of rats. One of the corn varieties was designed to tolerate broad-spectrum herbicides, (so-called 'Roundup-ready' corn), while the other two contain bacteria-derived proteins that have insecticide properties. The study made use of Monsanto's own raw data.
