A key ingredient in RoundUp, the world’s most widely used herbicide, is at the center of a battle over worker and environmental safety in Europe.
Glyphosate – the main active ingredient in the Monsanta-manufactured herbicide RoundUp, was classified as “probably carcinogenic to humans” by the World Health Organization's International Agency for Research on Cancer (IARC) in March 2015. However, the European Food Safety Agency (EFSA) subsequently rejected the WHO’s conclusions and declared that glyphosate poses "no carcinogenic hazard to humans" or any other health risk.
