Everything you need to know about Glyphosate and RoundUp safety

Farmers talking about weed management

There is much discussion about glyphosate, the active ingredient in most Roundup® brand herbicides and other weed-control products. Is it safe to use? What impact does it have on the environment? And more.


By sharing fact-based information and scientific findings from numerous independent sources, we want to show you that glyphosate is safe to use as directed and does not cause cancer in humans. 

Glyphosate-based herbicides are among the most widely-used crop protection products. For 50 years, it has been approved and used safely in modern agriculture and food production, vegetation management, lawn care, gardening and more.  


Due to its extensive history, rigorous testing and oversight, it’s one of the most studied herbicides in the world.  

All crop protection products, including glyphosate, are subject to rigorous testing and oversight by regulatory agencies worldwide. Regarding safety assessments, glyphosate-based herbicides are among the most extensively tested products, with more than 1,500 studies and 50 years of research. After reviewing the volume of scientific research and evaluations by regulatory agencies over the years, experts and regulators worldwide have concluded that glyphosate-based products can be used safely as directed.

As the population grows, the agricultural industry is continuously working to grow healthy crops with less impact on the environment. That means using less land and natural resources, preserving biodiversity, reducing greenhouse gas emissions and helping to ensure that soil stays rich with nutrients.


Providing farmers with tailored solutions designed to address these challenges is crucial. Glyphosate-based products provide efficient and safe crop protection. 

Bayer stands fully behind our glyphosate-based Roundup® products, which have been used safely and successfully around the world for 50 years.

Glyphosate-based herbicides are the most widely used and extensively tested herbicides on the market, which is a major reason why so many farmers and others around the world continue to rely on these products not only for effective weed control, but also to minimize tillage farming practices, reduce greenhouse gas emissions, preserve more land for native habitats, and provide enough food to meet the needs of a growing population worldwide.

Like all herbicides, glyphosate has been subject to rigorous testing and oversight by regulatory authorities. The leading health regulators around the world have repeatedly concluded that glyphosate-based products can be used safely as directed. Most recently, in November 2023, the EU Commission re-approved glyphosate for 10 years, following the favorable scientific assessments by its health and safety agencies, including the European Chemicals Agency (ECHA) and European Food Safety Authority (EFSA), which “did not identify any critical areas of concern.” The U.S. Environmental Protection Agency (EPA) and the regulatory authorities in Japan, Australia, Korea, Canada, New Zealand, and elsewhere have also recently reaffirmed that glyphosate-based products can be used safely as directed.
