Glyphosate, a herbicide widely marketed by Monsanto Co. and other companies, likely has the potential to cause cancer in humans, a World Health Organization agency said Friday.
The determination, published by researchers for the International Agency for Research on Cancer in a U.K. medical journal, is likely to fuel further debate over the safety of the heavily used agricultural chemical, which Monsanto sells under the Roundup brand.
Consumer and environmental groups have long warned of health problems that they say could arise from applying the weedkiller on farms, while agricultural companies have touted the product’s safety and environmental impact as preferable to other, harsher chemicals. Officials at Monsanto and agricultural-chemical trade groups contested Friday’s finding, saying decades of research had proved glyphosate’s safety.
In classifying glyphosate as potentially cancer-causing, the international research agency cited studies of occupational exposure to glyphosate in the U.S., Canada and Sweden, which they wrote showed “increased risks for non-Hodgkin lymphoma” along with a positive trend for some ailments in mice in separate studies.
