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.

Both Roundup-Ready corn and Roundup are toxic to humans: scientific evidence

Professor Gilles-Eric Séralini put out a press release yesterday, NEW STUDY: Genetically Modified Corn Toxic to Humans,
“We were very much surprised by our findings. Until now, it has been thought almost impossible for Bt proteins to be toxic to human cells. Now further investigations have to be conducted to find out how these toxins impact the cells and if combinatorial effects with other compounds in the food and feed chain have to be taken into account,” says Gilles-Eric Séralini from the University of Caen, who supervised the experiments. “In conclusion, these experiments show that the risks of Bt toxins and of Roundup have been underestimated.”
The toxicity of the corn itself may have been a surprise, but not that of Roundup:
These findings are in accordance with several other investigations highlighting unexpected health risks associated with glyphosate preparations.
Previous studies, including ones by Dr. Séralini, already showed exposure to glysophate (the active ingredient in Roundup) to be “a risk factor for developing Non-Hodgkin lymphoma”, and to be toxic to human umbilical, placental, and placental cells with a that “is far below agricultural recommendations and corresponds to low levels of residues in food or feed.” In Argentina, Prof. Andrés Carrasco has demonstrated birth defects in amphibians and there is increasing evidence of human birth defects.

Regarding Monsanto’s GM corn itself, we already knew it causes liver and kidney damage in rats (later reverified using Monsanto’s own data), and chickens fed feed including Monsanto corn show abnormal gene expression.

Now we have even more hard evidence of the toxicity of Monsanto’s GM corn and of Monsanto’s Roundup. The journal article is available through Wiley online.

GM crops cause organ disruptions —multiple studies

It’s not just the pesticides, it’s the crops themselves.

Gilles-Eric Séralini and colleagues surveyed the state of research and found GMOs Linked to Organ Disruption in 19 Studies, as Jeffrey Smith reports for the Institute for Responsible Technology.

…consuming genetically modified (GM) corn or soybeans leads to significant organ disruptions in rats and mice, particularly in livers and kidneys. …9% of the measured parameters, including blood and urine biochemistry, organ weights, and microscopic analyses (histopathology), were significantly disrupted in the GM-fed animals. The kidneys of males fared the worst, with 43.5% of all the changes. The liver of females followed, with 30.8%. The report, published in Environmental Sciences Europe on March 1, 2011, confirms that “several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects.” The authors point out that livers and kidneys “are the major reactive organs” in cases of chronic food toxicity.
And these were the corn and soybeans that people eat.

Here’s the study.

Why didn’t we know about this long ago? Continue reading →

Toxic corn and cotton pollute our streams

Steve Connor writes in The Independent 28 Sep 2010 that GM maize ‘has polluted rivers across the United States’:
An insecticide used in genetically modified (GM) crops grown extensively in the United States and other parts of the world has leached into the water of the surrounding environment.

The insecticide is the product of a bacterial gene inserted into GM maize and other cereal crops to protect them against insects such as the European corn borer beetle. Scientists have detected the insecticide in a significant number of streams draining the great corn belt of the American mid-West.

The researchers detected the bacterial protein in the plant detritus that was washed off the corn fields into streams up to 500 metres away. They are not yet able to determine how significant this is in terms of the risk to either human health or the wider environment.

This is the same “gene from the bacterium Bacillus thuriengensis (Bt)” used in Monsanto’s RoundUp Ready cotton and peanuts and soybeans. Since Continue reading →

Corn most profitable: not GM

Steve Connor writes in the Independent that It pays not to cultivate GM crops, survey finds,
The first economic analysis of growing genetically modified crops on a wide scale has found that the biggest winners were the farmers who decided not to grow them.

The study, which looked at maize yields in the corn belt of the United States, found that farmers who continued to grow conventional crops actually earned more money over a 14-year period than those who cultivated GM varieties.

The article then tries to say they nonetheless benefited from genetic modification:
All farmers benefited from the significantly lower level of pests that came about after the introduction of GM maize to the US in 1996, but the conventional farmers who continued to cultivate non-GM varieties also benefited financially from not having to pay the extra costs of purchasing GM seeds.
Um, what about not having to pay for the pesticides that go with the GM seeds? The study’s author admits they didn’t study that sort of thing:
“Additionally, environmental benefits from corn borer suppression are likely occurring, such as less insecticide use, but these benefits have yet to be documented,” Dr Hutchinson said.
The Telegraph spelled his name wrong. This appears to be the actual report:
Areawide Suppression of European Corn Borer with Bt Maize Reaps Savings to Non-Bt Maize Growers
W. D. Hutchison, E. C. Burkness, P. D. Mitchell, R. D. Moon, T. W. Leslie, S. J. Fleischer, M. Abrahamson, K. L. Hamilton, K. L. Steffey, M. E. Gray, R. L. Hellmich, L. V. Kaster, T. E. Hunt, R. J. Wright, K. Pecinovsky, T. L. Rabaey, B. R. Flood, and E. S. Raun (8 October 2010)
Science 330 (6001), 222. [DOI: 10.1126/science.1190242]
The full text is behind a paywall, but the abstract concludes with:
…and highlight economic incentives for growers to maintain non-Bt maize refugia for sustainable insect resistance management.
So growing 98% of crops from GM seeds, as is the case in Georgia, is a bad idea.

Monsanto Fined $2.5 Million

Jimmy Mengel EPA Slaps Monsanto with Record Fine, Million Dollar Settlement the Largest in Series of Penalties:
The agricultural giant was found to have been selling genetically modified cotton seeds without labeling them as such. Between 2002 and 2007, Monsanto’s seeds were illegally sold in several Texas counties where the seeds are explicitly banned.

The seeds — known as Bollgard and Bollgard II — were genetically engineered to produce the insecticide Bacillus thuringiensis (Bt), and Texas officials were concerned that using the seeds would lead to pest resistance.

But that didn’t stop Monsanto from bamboozling buyers into purchasing the illegal seeds.

Here’s the bad news: Monsanto’s market cap is $29.5 billion, so the fine is less than a hundredth of a percent of that.

Still, the fines keep going up. Maybe eventually they’ll get big enough to sting.

Or we could just trust the company that made Agent Orange and DDT.

Or we could remember this: Continue reading →

Mutant Pigweed vs. Glysophate-Resistant Corn, Soybeans, and Cotton

It’s a funny thing about monocultures. They’re highly vulnerable to anything that affects that particular variety. Dr. Mae-Wan Ho writes:
The scene is set at harvest time in Arkansas October 2009. Grim-faced farmers and scientists speak from fields infested with giant pigweed plants that can withstand as much glyphosate herbicide as you can afford to douse on them. One farmer spent US$0.5 million in three months trying to clear the monster weeds in vain; they stop combine harvesters and break hand tools. Already, an estimated one million acres of soybean and cotton crops in Arkansas have become infested.

The palmer amaranth or palmer pigweed is the most dreaded weed. It can grow 7-8 feet tall, withstand withering heat and prolonged droughts, produce thousands of seeds and has a root system that drains nutrients away from crops. If left unchecked, it would take over a field in a year.

Meanwhile in North Carolina Perquimans County, farmer and extension worker Paul Smith has just found the offending weed in his field [3], and he too, will have to hire a migrant crew to remove the weed by hand.

Here’s the good news: Continue reading →
