The IARC urged its scientists not to publish research documents on its 2015 weedkiller glyphosate review, according to Reuters. The agency told Reuters on Tuesday that it tried to protect the study from “external interference,” as well as protect its intellectual rights, since it was “the sole owner of such materials.”
The scientists had been asked earlier to release all the documentation on the 2015 report under US freedom of information laws.
The groundbreaking review, published in March 2015 by the IARC – a semi-autonomous agency of the World Health Organization (WHO) – labeled the glyphosate herbicide as “probably carcinogenic to humans.” Glyphosate is a key ingredient of Monsanto’s flagship weedkiller well-known under the trade name ‘Roundup.’ It is one of the most heavily used herbicides in the world and is designed to go along with genetically-modified “Roundup Ready” crops, also produced by Monsanto.
The IARC’s report caused problems for both the notorious agrochemical giant and the agency itself.
The report sparked a heated debate around the use of Roundup, and caused several EU countries – including France, Sweden, and the Netherlands – to object to the renewal of the glyphosate’s EU license. The vote on prolonging the glyphosate license for 15 years failed several times in June 2016, but the license was temporarily extended for 18 months during last hours before its expiration.
The controversial report has seemingly made the IARC a target for attacks from multiple directions, and raised scientific, legal, and financial questions.
Various critics, including those in the chemical industry, said the IARC’s evaluations are fuel for “unnecessary health scares,” since the IARC allegedly studies the potentially harmful substance itself, and not a “typical human” exposure to it. It remained unclear whether the critics urged a WHO body to test the potentially carcinogenic chemical on humans.
The critics also brought up other controversial statements from the IARC, over whether such things as mobile phones, coffee, red meat, and processed meat could cause cancer.
The agency defended its methods as scientifically sound and “widely respected for their scientific rigor, standardized and transparent process and…freedom from conflicts of interest.” Numerous freedom of information requests by the Energy & Environment Legal Institute (E&E Legal), a US conservative advocacy group, have since been turned down with this reasoning.
