Pesticide studies hitting a nerve

There’s quite the controversy about that recent study that shows that “inert” ingredients in Roundup are actually toxic. Apparently Dr. Séralini hit a nerve.

Some critics are making up stuff:

EFSA logo “The EFSA requested access to the raw data” —Jon Entine

That turns out not to be true:

No. EFSA has not requested raw data for the study as this information is not required at this stage of the review process.” —EFSA.

Monsanto logo Who previously actually did refuse to release raw data?

Monsanto only released the raw data after a legal challenge from Greenpeace, the Swedish Board of Agriculture and French anti-GM campaigners.

Here’s the European Food Safety Authority (EFSA)’s rather vague statement about the recent study and EFSA’s FAQ clarifying that statement.

Here’s a much more substantive response from scientists supporting the Séralini cell toxicity study. The last item of that response:

GMWatch logo CRITICISM: GM has been in the food chain for years in the US. Why isn’t there evidence of people and animals suffering more tumours or dying earlier? Why aren’t Americans “dropping like flies?”

RESPONSE: Most GM crops are fed to farm animals, which have relatively short lives either for meat or dairy production and so there is probably not enough time for tumours to develop.

Americans have been eating GM food (soya, maize) for only a relatively short time in significant quantities in processed foods. So it may be too short a period for long-term effects such as tumour formation to be noticeable. However, we should also note that there is no labelling of GM foods in the USA and no monitoring of the population for ill-effects, so if GM food were causing ill health this would be going undetected.

Ill effects of Roundup went mostly unstudied until scientists in places like Austria (the first study above) and France (the second study) and Canada and Continue reading

Roundup causes DNA damage even when vastly diluted

Roundup (you know, the stuff that’s sprayed on cotton, soybeans, peanuts, and corn and drifts across the road) causes DNA damage even when diluted down to 450 times less than what’s used in agriculture, according to a scientific study from February 2012.

Cytotoxic and DNA-damaging properties of glyphosate and Roundup in human-derived buccal epithelial cells, by Verena J. Koller, Maria Fürhacker, Armen Nersesyan, Miroslav Mišík, Maria Eisenbauer and Siegfried Knasmueller, Archives of Toxicology Volume 86, Number 5 (2012), 805-813, DOI: 10.1007/s00204-012-0804-8.

Glyphosate (G) is the largest selling herbicide worldwide; the most common formulations (Roundup, R) contain polyoxyethyleneamine as main surfactant. Recent findings indicate that G exposure may cause DNA damage and cancer in humans….

Since we found genotoxic effects after short exposure to concentrations that correspond to a 450-fold dilution of spraying used in agriculture, our findings indicate that inhalation may cause DNA damage in exposed individuals.

It’s probably not even the “active” ingredient, glyphosate, that’s causing this DNA damage, more likely one of its “inert” ingredients.

Genetic engineering based on obsolete science and regulatory capture –peer-reviewed research

Here is peer-reviewed evidence that we are the guinea pigs for worldwide experimentation on the food supply using fatally-flawed science. Experimentation that isn’t needed because we already know how to do it right.

We already knew Monsanto is blocking independent GMO research in the U.S. (L.A. Times op-ed) and there are numerous examples of Monsanto gaming regulatory systems. Now Ken Rosenboro of The Organic and Non-GMO Report tells us there’s peer-reviewed research that says:

…the technology is based on obsolete science, that biotechnology companies such as Monsanto have too much influence on government regulators and “public” universities, and that university scientists are ignoring the health and environmental risks of GM crops.
The research is published as two papers by Don Lotter in the International Journal of the Sociology of Agriculture and Food:

Part 1: The Development of a Flawed Enterprise

Part 2: Academic Capitalism and the Loss of Scientific Integrity

In a 7 August 2009 article in FoodFirst, The Genetic Engineering of Food and the Failure of Science, Don Lotter explains what’s in those two papers: Continue reading

2,4-D: Back to the Past

So, having just spent a decade breeding mutant superweeds by pouuring pesticides on crops, what’s the recommended future of weed science?

Pour pesticides on crops until they breed more mutant superweeds.

So what is our old friend 2,4-D, which used to be commonly used back in the 1980s? Continue reading

Hamster Roundup: sterility and infant mortality

Jeffrey Smith writes in Huffingtonpost about Genetically Modified Soy Linked to Sterility, Infant Mortality in Hamsters:
“This study was just routine,” said Russian biologist Alexey V. Surov, in what could end up as the understatement of this century. Surov and his colleagues set out to discover if Monsanto’s genetically modified (GM) soy, grown on 91% of US soybean fields, leads to problems in growth or reproduction. What he discovered may uproot a multi-billion dollar industry.

After feeding hamsters for two years over three generations, those on the GM diet, and especially the group on the maximum GM soy diet, showed devastating results. By the third generation, most GM soy-fed hamsters lost the ability to have babies. They also suffered slower growth, and a high mortality rate among the pups.

Not just a little higher: five times highher infant mortality.

And it’s not necessarily the soybeans themselves: Continue reading
