Ten years of GM soy and glyphosate poisoning have escalated the rates of cancer and birth defects. Claire Robinson
Argentina has become a giant experiment in farming genetically modified (GM) Roundup Ready (RR) soy, engineered to be tolerant to Roundup, Monsanto’s formulation of the herbicide glyphosate. The Argentine government, eager to pull the country out of a deep economic recession in the 1990s, restructured its economy around GM soy grown for export, most of which goes to feed livestock in Europe. In 2009, GM soy was planted on 19 million hectares - over half of Argentina’s cultivated land - and sprayed with 200 million litres of glyphosate herbicide [1]. Spraying is often carried out from the air, causing problems of drift.
In 2002, two years after the first big harvests of RR soy in the country, residents and doctors in soy producing areas began reporting serious health effects from glyphosate spraying, including high rates of birth defects as well as infertility, stillbirths, miscarriages, and cancers [2]. Environmental effects include killed food crops and livestock and streams strewn with dead fish [2, 3].
One of the first medical doctors to report problems from glyphosate spraying of GM soy was Dr Darío Gianfelici, from Cerrito, Entre Ríos, Argentina. According to Gianfelici, there are two levels of toxic effects from glyphosate: acute effects, such as vomiting, diarrhoea, respiratory problems, and skin rashes; and chronic effects, which take 10–20 years to show up. These include infertility and cancer [4].
Gianfelici said [4]: “Our town experienced drastic changes before and after soy. I’ve seen people die from cancer at age 30. I have witnessed pregnancy problems and a significant increase in fertility problems. I have seen an increase in respiratory diseases, as has never been seen before.
“GM soy has been a death sentence for humans and for the environment. No money can compensate for the damage that has been caused – the contamination, the deaths, the cases of cancer and malformations.”
Reports of birth defects in glyphosate-sprayed areas of Argentina gained scientific credibility in 2009, when senior Argentine government scientist Prof. Andrés Carrasco went public with his research findings, fully published a year later [1], that glyphosate causes malformations in frog and chicken embryos at doses far lower than those used in agricultural spraying (see [5] Lab Study Establishes Glyphosate Link to Birth Defects, SiS 48). “The findings in the lab are compatible with malformations observed in humans exposed to glyphosate during pregnancy,” said Carrasco [6], “I suspect the toxicity classification of glyphosate is too low ... in some cases this can be a powerful poison.”
At a recent conference, Carrasco, professor and director of the Laboratory of Molecular Embryology, University of Buenos Aires Medical School and lead researcher of the National Council of Scientific and Technical Research (CONICET), said a frequent result of malformations in human embryos is miscarriage. He said that it was now not unusual for women in GM soy producing regions of Argentina to have up to five miscarriages in a row [7].
The research findings of Carrasco and his colleagues were not welcomed by some sectors of government and industry. After he announced them, four people from Argentina’s crop protection trade association CASAFE were sent to try to search his laboratory and he was “seriously told off” by Lino Barrañao, Argentina’s science and technology minister [6].
Things took a violent turn in 2010, when an organized mob of thugs attacked people who gathered to hear Carrasco talk in La Leonesa, an agricultural town that has become a centre for activism against agrochemical spraying of soy and rice crops. Three people were seriously injured. Carrasco and a colleague shut themselves in a car and were surrounded by people making violent threats and beating the car for two hours [8]. Witnesses said the attack was organized by local officials and a local rice producer to protect the economic interests behind local agro-industry. Amnesty International has called for an investigation.
Based on Carrasco’s findings and other reports of health problems from spraying, the Environmental Lawyers Association of Argentina petitioned the Supreme Court of Argentina to ban the use of glyphosate (see [9] Glyphosate Herbicide Could Cause Birth Defects, SiS 43). But such is Argentina’s dependence on the GM soy farming model that Guillermo Cal, executive director of CASAFE, said [6] a ban would mean “we couldn’t do agriculture in Argentina”. In addition, the cash-strapped Argentine government relies heavily on tariffs levied on soy exports and is protective of the industry.
No national ban on glyphosate has yet been implemented. But in March 2010, just months after the release of Carrasco’s findings, a lawsuit brought by sprayed residents resulted in a regional court banning the spraying of agrochemicals near populated areas of Santa Fe province [10]. The ruling was revolutionary in that it implemented the precautionary principle and reversed the burden of proof [11]. No longer do residents have to prove that agrochemical spraying causes harm, but the government and soy producers have to prove it is safe.
Viviana Peralta, a housewife, instigated the lawsuit. She and her family were hospitalized following aerial spraying near her home. Her newborn baby had turned blue and Peralta herself suffered respiratory problems. Peralta said, “When I saw my baby like that, I said [11], “Enough. This cannot go on.” ”
Shortly after the residents’ court victory, a commission of the provincial government of Chaco state reported that between 2000 and 2009, the rate of childhood cancers tripled in La Leonesa and the birth defects increased nearly fourfold over the entire province [12]. These staggering rises in disease coincided with the expansion of the agricultural frontier into Chaco province and the resulting rise in agrochemical use. The commission identified the main problem as glyphosate and other agrochemicals applied to “transgenic crops, which require aerial and ground spraying (dusting) with agrochemicals”.
A member of the Chaco commission, who did not want to be identified due to the “tremendous pressures” they were under, said [13], “all those who signed the report are very experienced in the subject under study, but rice and soy planters are strongly pressuring the government. We don’t know how this will end, as there are many interests involved.”
Speaking at a conference, Carrasco noted the irony that Argentina’s people are suffering from the production of a commodity (GM soy) destined for Europe, which European consumers do not want [7]. Europe imports around 38 million tonnes of soy per year [14], much of which is GM soy sprayed with glyphosate. Because of consumer resistance to GM, most of it ends up hidden in animal feed.
Carrasco found malformations in frog and chicken embryos injected with 2.03 mg/kg glyphosate – nearly ten times lower than the maximum residue limit (MRL) for glyphosate allowed in soy in the EU (20 mg/kg) [15]. Soybeans have been found to contain glyphosate residues at levels up to 17mg/kg [16].
Defenders of glyphosate may say that these figures do not show a risk to consumers, because embryos are designed to keep toxins out. However, studies show that the added ingredients (adjuvants) in Roundup make cell membranes more permeable to glyphosate, increasing its toxicity to cells [17, 18].
Even without soy, glyphosate is all around us. Apart from its use in agriculture, Roundup is marketed to home gardeners as safe to use around children and pets. It is sprayed on schoolyards and verges by local authorities. The myth of Roundup’s safety persists despite two court rulings forcing Monsanto to withdraw advertising claims that Roundup is biodegradable and environmentally friendly [19, 20].
In reality, the research of Carrasco’s team is the latest in a long list of peer-reviewed studies showing dangers to health and the environment from glyphosate. Many of these studies are collected in a new report co-authored by nine international scientists [21], “GM Soy: Sustainable? Responsible”. The report challenges claims of sustainability for GM soy and the glyphosate herbicide on which it relies. Published by GLS Bank, Germany and ARGE Gentechnik-frei, Austria’s GM-free industry association, the report has been released together with the powerful testimonies of Argentine people affected by glyphosate spraying on GM soy [22].
Carrasco remains humble about his study, saying [11], “The origin of my work is my contact with the communities victimized by agrochemical use. They are the irrefutable proof of my research.” So the final word on the claimed safety of glyphosate and other agrochemicals sprayed on GM soy must go to Peralta. She said [11]: “I do not know about chemistry, I did not go to university, but I know what my whole family has suffered. To people who are not familiar with this model of agriculture, I say: Do not trust these companies. Reject agrochemicals. Do it for the life of your children.”

Have you not heard? Soy is poisionous
Read: Soy...the dark cinderella
25 years ago the only place you could find soy is in the hardware store in paint thinner

Phlip Dawes expresses my opinion better than I ever could have. It is very unfortunate tgat Argentina was "used" as a guineapig It is a beautiful country and if I ever wanted to travel antwhere Buenos Aires would be ine of my first chice destinations...I was there for 5 weeks and it was one of the best times in my life. My heart goes out to all those who have been and are to be effected by the Agro-cheical companies. God Bless and save us from these Monsters that are out to profit at the expence of a toxic world-wide epidemic of disease ...which in fact the pharmeceutical companies would love so their pockets get fatter as well!

Philip Dawes, I really really hopes so. But, for this occur we must do more than merely dream.

I keep asking San Francisco, California's city council to pass a law banning the use of Monsanto's RoundUp on city-owned lands. I can't see why they don't take it up.

The time will come when the criminal scientists who created GM crops and the various toxic chemicals to assist their growth, will be brought to justice and charged with crimes against humanity, genocide and crimes against wildlife and the environment, and with them, the psychopathic heads of the GM seed producing and agro-chemical companies will be imprisoned for life. The world is fast changing, with people finally awakening. No longer must we tolerate the criminality of our leaders and heads of multinationals whose sole interests are power and profits. The world needs honest and ethical leaders, not the present morons that rule the roost…

The governments and legislators are the ones who heed to read and understand this information then act on behalf of their citizenry and BAN the use these chemicals and pesticides. Then the GMO's could not be used.
