U.N. committee finds Monsanto weed killer glyphosate unlikely to cause cancer
In a statement likely to intensify a row over its potential health impact, experts from the U.N.'s Food and Agriculture Organization (FAO) and World Health Organization (WHO) said glyphosate is "unlikely to pose a carcinogenic risk to humans" exposed to it through food. It is mostly used on crops.
Having reviewed the scientific evidence, the joint WHO/FAO committee also said glyphosate is unlikely to be genotoxic in humans. In other words, it is not likely to have a destructive effect on cells' genetic material.
The conclusion contradicts a finding by the WHO's Lyon-based International Agency for Research on Cancer (IARC), which in March 2015 said glyphosate is "probably" able to cause cancer in humans and classified it as a so-called Group 2A carcinogen.
Seven months after the IARC review, the European Food Safety Authority (EFSA), an independent agency funded by the European Union, published a different assessment, saying glyphosate is "unlikely to pose a carcinogenic hazard to humans".
The differing findings thrust glyphosate into the center of a row involving EU and U.S. politicians and regulators, the IARC experts, environmental and agricultural specialists and the WHO.
Diazinon and malathion, two other pesticides reviewed by the WHO/FAO committee, which met last week and issued its conclusions in a statement on Monday, were also found to be unlikely to be carcinogenic.
