Monsanto’s flagship pesticide linked to cancer and antibiotic resistance

PAN International calls for strong global response


The International Agency for Research and Cancer (IARC) of the World Health Organization (WHO) has labeled glyphosate as “probably carcinogenic to humans”. 


The IARC concluded that there is sufficient evidence of carcinogenicity in experimental animals. The decision was made after 17 scientists met on March 20 at the IARC to assess the carcinogenicity of the herbicide glyphosate and 4 organophosphate pesticides.


“Monsanto’s weed-killer glyphosate is wreaking havoc with the health of children and rural communities in Argentina,” said Javier Souza, chair of Pesticide Action Network International. “Thousands of people suffer from glyphosate poisoning related illnesses and the cancer rates are two to four times higher than the national average”. Souza from Argentina, referred to his country’s 24 million hectares of crops, mostly soybeans, genetically engineered (GE) to resist glyphosate. In 2014, 79 million gallons of glyphosate were applied on soybeans and other crops in Argentina. Ahead of Argentina is Brazil with 40 million hectares of GE crops, mostly soybeans. Uruguay, Paraguay, and Bolivia also grow millions of hectares with GE soy resistant to glyphosate.


Monsanto is the creator of its brand-name herbicide Roundup, containing the active ingredient glyphosate, and of GE soybean, corn, and cotton resistant to withstand applications of glyphosate. Glyphosate has become the most heavily used herbicide in the world, bringing billions of dollars in profits to the giant biotech company. In the United States, about 94%  soybeans, 89% corn, 91% cotton are GE resistant to glyphosate.


“Glyphosate and other herbicides have been linked to antibiotic resistance,” said Judy Hatcher, vice-chair of PAN International. “The combination of carcinogenicity and antibiotic resistance by Monsanto’s flagship pesticide are two loud wake-up calls for the global community. Policymakers as a matter of highest priority, should keep the next wave of genetically engineered seeds – containing glyphosate and other old, hazardous chemicals – off the market” she added.


Researchers in New Zealand have found that formulations of herbicides containing glyphosate, 2,4-D, and dicamba can lead to development of antibiotic resistance in disease-causing bacteria, such as E. coli and Salmonella.


“In Asia glyphosate is widely used and the link with carcinogenicity and antibiotic resistance is an area of concern for farmers and agricultural workers who are exposed” said Sarojeni Rengam from PAN Asia Pacific. 


“Experience in Africa and other parts of the world show that toxic agrochemicals affect the poorest of the poor, and this situation cannot go on as usual” said Abou Thiam from PAN Africa. 


“Hazardous pesticides are part of an obsolete technology and don’t belong in agriculture” added Keith Tyrell from PAN UK. Carina Weber from PAN Germany remarked “This is an opportunity for policymakers to exercise their political will and move the world forward towards sustainable, healthy agriculture, free from toxins”.


As a result of the new research, PAN International calls on governments and policymakers to take first emergency measures to curtail and stop the use of herbicide formulations containing glyphosate applied to genetically engineered seeds and crops. And the network urges governments to develop action plans within the next 60 days to layout how they will address the concerns highlighted in recent studies. Furthermore, PAN International urges governments to stop the release and marketing of highly hazardous pesticides, and establish policies to promote safer agricultural practices that protect workers, consumers, the environment, and provides a dignified living to farmers.




Pesticide Action Network (PAN) is a network of over 600 participating nongovernmental organizations, institutions and individuals in over 90 countries working to replace the use of hazardous pesticides with ecologically sound and socially just alternatives.
