The herbicide glyphosate, sold by Monsanto in its Roundup weed killer product and widely used in agriculture and by gardeners, is unlikely to cause cancer in people, according to a new safety review by United Nations health, agriculture and food experts.
In a statement likely to intensify a row over its potential health impact, experts from the U.N.'s Food and Agriculture Organization (FAO) and World Health Organization (WHO) said glyphosate is "unlikely to pose a carcinogenic risk to humans" exposed to it through food. It is mostly used on crops.
Having reviewed the scientific evidence, the joint WHO/FAO committee also said glyphosate is unlikely to be genotoxic in humans. In other words, it is not likely to have a destructive effect on cells' genetic material.
Diazinon and malathion, two other pesticides reviewed by the committee, which met last week and published its conclusions on Monday, were also found to be unlikely to be carcinogenic.
"In view of the absence of carcinogenic potential in rodents at human-relevant doses and the absence of genotoxicity by the oral route in mammals, and considering the epidemiological evidence from occupational exposures, the meeting concluded that glyphosate is unlikely to pose a carcinogenic risk to humans from exposure through the diet," the committee said.
Glyphosate is also "unlikely to be genotoxic at anticipated dietary exposures," it added.
The group reaffirmed an acceptable daily intake (ADI) of up to 1 milligram of glyphosate for every kilogram of body weight.
