The U.S. Environmental Protection Agency has said that glyphosate, the key ingredient in Monsanto Co.’s top-selling weedkiller Roundup, is not likely to be carcinogenic to humans, contradicting a World Health Organization panel.
The EPA, in a draft risk assessment report issued on Monday, also said it found “no other meaningful risks to human health” when glyphosate, the world’s biggest-selling weedkiller, is used according to its label instructions.
For more than 40 years, farmers have applied glyphosate to crops, most recently as they have cultivated genetically modified corn and soybeans. Roundup is also sprayed on residential lawns and golf courses.
The WHO’s International Agency for Research on Cancer, or IARC, fueled concerns about health risks when it said in 2015 that glyphosate was “probably carcinogenic.”
Monsanto, which is being acquired by Bayer AG, rejected the conclusion along with groups representing U.S. corn, soy and wheat farmers, citing other reviews.
The EPA’s latest assessment “confirms exactly what we’re saying: that agencies across the world say glyphosate is safe and the IARC report is a flawed analysis,” Gordon Stoner, president of the National Association of Wheat Growers, said on Wednesday.
