Roundup bred mutant pigweed

With GM crops come herbicides, which breed resistant weeds. This has happened in about a decade for the worse mutants. We can reverse the problem by reversing the spraying, using plowing, cultivation, and crop rotation instead.

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.

Parkinson’s and Roundup: latest in a long list

We already knew Argentinian farmers were suing Monsanto about Roundup-induced birth defects, including cerebral palsy, down syndrome, psychomotor retardation, missing fingers, and blindness; we knew Roundup’s active ingredient glyphosate was “a risk factor for developing Non-Hodgkin lymphoma”; we knew that Roundup-ready corn causes liver and kidney damage in rats and chickens fed feed including Monsanto corn show abnormal gene expression, and we knew that Roundup-ready corn is toxic to humans. Add to all that: Roundup is a risk for Parkinson’s disease.

Sayer Ji wrote for GreenMediaInfo 18 April 2012, Roundup Herbicide Linked To Parkinson’s-Related Brain Damage,

Alarming new research published in the journal Neurotoxicology and Teratology supports the emerging connection between glyphosate, the active ingredient in Roundup herbicide, and neurodegenerative conditions such as Parkinson’s disease and Parkinsonian disorders.

Published this month (April, 2012), the new study entitled “Glyphosate induced cell death through apoptotic and authophagic mechanisms,” investigated the potential brain-damaging effects of herbicides, which the authors stated “have been recognized as the main environmental factor associated with neurodegenerative disorders, such as Parkinson’s disease.”1

They found that glyphosate inhibited the viability of differentiated test cells (PC12, adrenal medula derived), in both dose-and-time dependent manners. The researchers also found that “glyphosate induced cell death via authophagy pathways in addition to activating apoptotic pathways.”

Roundup herbicide is now a ubiquitous contaminant in our air, rain, groundwater, and food, making complete avoidance near impossible. A growing body of experimental evidence now indicates that it in addition to its neurotoxicity it also has the following.

Cancer in the Air, Food, and Water

Lyndsey Layton writes in the Washington Post that:
An expert panel that advises the president on cancer said Thursday that Americans are facing “grievous harm” from chemicals in the air, food and water that have largely gone unregulated and ignored.
Somebody noticed!

The President’s Cancer Panel called for a new national strategy that focuses on such threats in the environment and workplaces.

Epidemiologists have long maintained that tobacco use, diet and other factors are responsible for most cancers, and that chemicals and pollutants cause only a small portion — perhaps 5 percent.

The presidential panel said that figure has been “grossly underestimated” but it did not provide a new estimate.

“With the growing body of evidence linking environmental exposures to cancer, the public is becoming increasingly aware of the unacceptable burden of cancer resulting from environmental and occupational exposures that could have been prevented through appropriate national action,” the panel wrote in a report released Thursday.

Federal chemical laws are weak, funding for research and enforcement is inadequate, and regulatory responsibilities are split among too many agencies, the panel found.

The problem is not too many agencies. Here’s the problem: 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

Non-GMO Uprising Predicted by supermarket trade publication

Jeffrey M. SMith writes in the Food Freedom blog that Supermarket News Forecasts Non-GMO Uprising:
For a couple of years, the Institute for Responsible Technology has predicted that the US would soon experience a tipping point of consumer rejection against genetically modified foods; a change we’re all helping to bring about. Now a December article in Supermarket News supports both our prediction and the role the Institute is playing.
“The coming year promises to bring about a greater, more pervasive awarenes” of the genetically modified organisms (GMOs) in our food supply, wrote Group Editor Robert Vosburgh, in a trade publication that conventional food executives and retailers use as a primary source of news and trends in the industry. Vosburgh describes how previous food “culprits” like fat and carbs “can even define the decade in which they were topical,” and suggests that GMOs may finally burst through into the public awareness and join their ranks.

Vosburgh credits two recent launches with “the potential to spark a new round of concern among shoppers who are today much more attuned to the ways their food is produced.” One is our Institute’s new non-GMO website, which, he says, “provides consumers with a directory of non-GMO brands . . . developed ‘for the 53% of Americans who say they would avoid GMOs if labeled.’”

More than half of Americans? And that’s before most Americans learn that GM corn causes liver and kidney damage in rats and RoundUp causes human birth defects. Perhaps Monsanto is the new RJ Reynolds….

But that doesn’t mean big food won’t fight back. The Supermarket News article ends by taking the Forbes line that all Monsanto needs is better PR: Continue reading
