Fast Facts on Glyphosate and
Glyphosate-Based Herbicides

  • Long history of safe use: For more than 40 years, farmers – as well as governments, gardeners, and other users – have depended on glyphosate as an efficient and cost-effective tool that can be used safely to control weeds.

  • Conservation benefits: Glyphosate-based herbicides help farmers deliver crops to markets while promoting sustainable farming by reducing soil tillage, soil erosion and carbon emissions.
  • Extensive scientific backing: There is an extensive body of research on glyphosate and Monsanto/Bayer’s glyphosate-based herbicides, including more than 800 rigorous studies submitted to EPA, European and other regulators in connection with the registration process, that confirms that these products are safe when used as directed.
  • Not carcinogenic: The largest epidemiology study – the 2018 independent National Cancer Institute-supported long-term study that followed over 50,000 pesticide applicators for more than 20 years – found no association between glyphosate-based herbicides and cancer. Additionally, EPA’s 2017 cancer risk assessment examined more than 100 studies the agency considered relevant and concluded that glyphosate is ‘not likely to be carcinogenic to humans,’ its most favorable rating.

  • Favorable conclusions of regulators and international agencies around the world: The conclusions of leading regulators and agencies around the world, including the U.S. Environmental Protection Agency (EPA), European Food Safety Authorities (EFSA), European Chemicals Agency (ECHA), German BfR, and Australian, Canadian, Korean, New Zealand and Japanese regulatory authorities, as well as the Joint FAO/WHO Meeting on Pesticide Residues (JMPR), continue to support the safety of glyphosate‐based products when used as directed and that glyphosate is not carcinogenic. In April 2019, the EPA’s interim registration review decision on glyphosate reaffirmed that ‘there are no risks to public health when glyphosate is used in accordance with its current label and that glyphosate is not a carcinogen.’
