A peer-reviewed Massachusetts Institute of Technology report published in the scientific journal Entropy points to evidence that residues of glyphosate, the chief ingredient in Roundup weed killer, manufactured by Monsanto and sprayed over millions of acres of crops, has been found in food. The residues enhance the damaging effects of other food-borne chemicals and toxins in the environment known to disrupt normal body functions and induce disease, including Parkinson’s, infertility and cancers.

Reuters reports that environmentalists, consumer groups and plant scientists from several countries have warned that heavy use of glyphosate is harming plants, people and animals. The U.S. Environmental Protection Agency is conducting a standard registration review of glyphosate to determine by 2015 if its use should be limited. Yet Monsanto continues to claim that glyphosate is safe and less damaging than other commonly used herbicides.
