The draft human health and ecological risk assessments for glyphosate are being released for public comment by the EPA.

No risk to human health

The draft human health risk assessment concludes that glyphosate is not likely to be carcinogenic to humans.  The agency’s assessment found no other meaningful risks to human health when the product is used according to the pesticide label.  The agency’s scientific findings are consistent with the conclusions of science reviews by a number of other countries as well as the 2017 National Institute of Health Agricultural Health Survey.

EPA’s human health review evaluated dietary, residential/non-occupational, aggregate, and occupational exposures. Additionally, the agency performed an in-depth review of the glyphosate cancer database, including data from epidemiological, animal carcinogenicity, and genotoxicity studies.

Potential for plant, animal impacts  

The ecological risk assessment indicates that there is potential for effects on birds, mammals, and terrestrial and aquatic plants. EPA used the most current risk assessment methods, including an evaluation of the potential effects of glyphosate exposure on animals and plants. Full details on these potential effects as well as the EPA’s methods for estimating them, can be found within the ecological risk assessment.

More information

To read the draft risk assessments and supporting documents, go to http://www.epa.gov/ingredients-used-pesticide-products/draft-human-health-and-ecological-risk-assessments-glyphosate. The draft risk assessments and supporting documents will be available in glyphosate’s registration review docket EPA-HQ-OPP-2009-0361 on http://www.regulations.gov/ in early 2018. EPA will open a 60-day public comment period for the draft risk assessments, evaluate the comments received, and consider any potential risk management options for this herbicide.

What’s ahead

EPA is scheduled to publish the proposed interim registration review decision for glyphosate in 2019. The proposed interim registration review decision will outline any proposed mitigation measures to reduce risk, if any are needed.
