A new study indicates that heavy use of the world's most popular herbicide, Roundup, could be linked to a number of health problems and diseases, including Parkinson's, infertility and cancers, Reuters reports.
The peer-reviewed report, published recently in the scientific journal Entropy, said evidence indicates that residues of glyphosate, the chief ingredient in Roundup weed killer, has been found in food.
Roundup is sprayed over millions of acres of crops grown across Minnesota, the Midwest and the world.
Monsanto and others in the industry have long said glyphosate is proven safe. Jerry Steiner, Monsanto's executive vice president of sustainability, again stressed that in a recent interview, Reuters noted.
"We are very confident in the long track record that glyphosate has. It has been very, very extensively studied," Steiner said.
