Campaigners have said the European Commission must be stopped from proceeding with the renewed authorisation in the European Union of the toxic herbicide glyphosate, the active ingredient in Monsanto’s Roundup and the world’s most widely-used herbicide.

The demand from the global food and farming union IUF and Pesticide Action Network (PAN) International, comes as renewed authorisation is being pushed through despite an International Agency for Research on Cancer (IARC) warning last year that glyphosate is probably carcinogenic to humans and other evidence of the impact of glyphosate on food and health.

IUF and PAN International are calling for a deluge of messages to be sent to the European Commission and its relevant bodies “urging them to ban glyphosate in the EU and to provide comprehensive support for a safer, saner food system which does not put agricultural workers in the front lines of exposure and inject massive quantities of toxic chemicals into the environment.”
