On March 20th, the Center for Food Safety and The National Resource Defense Council filed lawsuits against the EPA over the continued use of glyphosate on U.S. farms.  The petitioners claim that glyphosate poses a health risk to humans. 

Their claims are based on the spurious findings of The World Health Organizations Subsidiary IARC that classified the herbicide as a "probable carcinogen." The classification was subsequently amended in response to protests by environmental scientists affiliated with academia and industry.

A number of lawsuits have ruled against Monsanto and holding company Bayer AG with allegations that glyphosate was responsible for non-Hodgkin lymphoma.
