Health Dangers of Roundup

Updated February 21, 2017

Roundup is the Monsanto chemical company's top-selling weed-killer worldwide, and is used in public parks, home gardens and commercial agriculture. Some 75 per cent of the genetically created food grown around the globe is designed to be raised in fields that also use Roundup weed-killer. Farmers are sold genetically modified (GM) seed created by Monsanto with the promise that the resulting crops are resistant to its Roundup weed-killer, so the herbicide kills the weeds, but not the crops. The inert ingredients in Roundup, as well as glyphosate, are a severe health risk.

Birth Defects

Studies led by Professor Gilles-Eric Seralini at the University of Caen in Caen, France, have shown that Roundup causes cell abnormalities in the human placenta. Roundup "is toxic to human placental cells, killing a large proportion of them after 18 hours of exposure at concentrations below that in agricultural use," according to the study. A subsequent study by the University of Buenos Aires Medical School has shown that exposure to Roundup causes malformations in frog and chicken embryos. The rate of birth defects and malformations in Argentina began increasing two years after the area was sprayed with Roundup.


Late-term spontaneous abortions increased by nearly 50 per cent in an epidemiological study of an Ontario, Canada, farm area where Roundup was used. Roundup is sprayed aerially over large areas of soybean and corn crops worldwide, and it effects agricultural workers, nearby residents and urban populations. Scientists warn that Roundup residues have entered the foodchain and are a river contaminant. "They have become a food product, since they are used on GMOs (genetically modified food), which can absorb them without dying," according to Gilles-Eric Seralini, head scientist of the University of Caen study.


The toxic effect of Roundup was found to increase with time, even at low doses. A study by Hardell and Eriksson, as reported in "Scientific American," found a link between exposure to Roundup and non-Hodgkins lymphoma. Non-Hodgkins lymphoma is a cancer of the lymph system. Its initial symptoms are swellings in the lymph nodes at the base of the neck. The American Cancer Society reports an 80 per cent increase in this form of cancer since the 1970s.
