Glyphosate is a vital tool for sustainable agriculture. For example, glyphosate has helped farmers adopt conservation tillage. With conservation tillage, farmers can disturb less soil and drive their tractors less. As a result, farmers can reduce soil erosion and carbon emissions.

Glyphosate has a more than 40-year history of safe use. Over those four decades, there have been more than 800 scientific studies and reviews that prove glyphosate is safe for use. The National Institutes of Health (NIH) and the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) both recently reaffirmed glyphosate does not cause cancer. The U.S. Environmental Protection Agency (EPA) and other regulatory authorities in Europe, Canada, Japan, Australia, Korea, and elsewhere routinely review all approved pesticide products and have consistently reaffirmed that glyphosate does not cause cancer.

In March 2015, a group called IARC incorrectly classified glyphosate as a “probable carcinogen.” IARC is the same organization that determined beer, meat, cell phones, and coffee cause cancer. IARC is not a regulatory authority and did no independent studies. IARC is one of four programs within the World Health Organization (WHO) that has reviewed glyphosate, and the only one to have made such a finding.

Investigative reports by Reuters (here and here) and the Times of London (here) have uncovered that IARC members reviewing glyphosate concealed important scientific data, edited out the conclusions of key studies, and were closely aligned with U.S. trial lawyers. 

IARC is an Outlier

IARC’s classification is inconsistent with the overwhelming consensus of regulatory authorities and other experts around the world, who have assessed all the studies examined by IARC – and many more. While IARC’s erroneous classification has attracted media attention and been used repeatedly by certain anti-agriculture organizations to generate unwarranted fear and confusion, regulators around the world continue to support the safe use of glyphosate. Following are regulatory and other expert conclusions on glyphosate that have been announced in just the short time since IARC inappropriately classified glyphosate.

United States Environmental Protection Agency (EPA)
December 2017
“The draft human health risk assessment concludes that glyphosate is not likely to be carcinogenic to humans.”

“Moreover, it was concluded that animal testing found no carcinogenic association and health risk of glyphosate on farmers was low. … A large-scale of epidemiological studies on glyphosate similarly found no cancer link.”
