Organ Damage In Rats From Monsanto GMO Corn
jenningsthecat writes "A study published in December 2009 in the International Journal of Biological Sciences found that three varieties of Monsanto genetically-modified corn caused damage to the liver, kidneys, and other organs of rats. One of the corn varieties was designed to tolerate broad-spectrum herbicides, (so-called 'Roundup-ready' corn), while the other two contain bacteria-derived proteins that have insecticide properties. The study made use of Monsanto's own raw data. Quoting from the study's 'Conclusions' section: 'Our analysis highlights that the kidneys and liver as particularly important on which to focus such research as there was a clear negative impact on the function of these organs in rats consuming GM maize varieties for just 90 days.' Given the very high prevalence of corn in processed foods, this could be a real ticking time bomb. And with food manufacturers not being required by law to declare GMO content, I think I'll do my best to avoid corn altogether. Pass the puffed rice and pour me a glass of fizzy water!"
If it's going to damage my liver, I'm switching to scotch. I'm sorry, Jack, but I just can't take the chance...
The invisible hand of the free market made the data and research invisible.
You are welcome on my lawn.
as a scientist, it has two things I dislike listed on its webpage... 1. In a prominent position its "unofficial IMPACT FACTOR" ... ugh.
2. In a prominent position its "UNOFFICIAL impact factor" ... well, if TR/ISI can't find it important enough to tabulate (assuming this is what unofficial indicates), why should we care :(
in fact, this is the first time I have heard of the journal ... if the work is more widely useful, we not publish in a more widely-read journal?
During the 19th century the issue was contaminated food produced by the new breed of large processed food manufacturers: in the early 20th it was the meat packing industry. Now it's Monsanto. In the first two cases it turned out industry was unfit to regulate itself, and bribery of Government officials was rife. But nowadays we regard processed food manufacturers as mostly benign (well, except for the junk food industry), and nobody worries about tinned meat. Regulation in the end was good for the industry. Monsanto needs to stop pissing on anyone who suggests it isn't perfect, and start to come clean. It would be in its long term benefit.

The study shows no organ damage. This is a lie by the esteemed Slashdot editor.
The study shows slight changes in some parameters which could be signs of damage. It could also not be. Eating sausages will give you different kidney readings from eating chicken, yet neither sausages nor chicken has been banned. Correspondingly the study says these are "signs of toxicity and not proof of toxicity". I would have expected KDawsons "organ damage" to imply that organ damage had been found.
Some data seems surprising - there is a significant effect for female rats consuming 11% Monsanto corn, but not male rats or female rats consuming 33%?
Although I agree that multiple year teasts should be performed, and organ damage checked for. Though it would be extremely surprising if this has not already been done by anyone.
Of course, since I write this I must be paid by Monsanto or just be evil, since all good-thinking progressives would never question criticism of an evil megacorp like Monsanto.
This is exactly right. The reason GMO corn exists and is widespread is that the gov't has incentivized corn production so much that it is practical to grow huge fields of it. This crop monoculture results in the excessive need of pesticides, hence the requirement of "Roundup-ready" crops in the first place.
They do it through lawsuits. They are a very litigious company as they sue their own customers for failing to disclose harvest data and seed information. Since they patended certain varieties of soybeans and corn, you cannot keep seed from one year to the next. Also, a neighboring farmer who has his own non-Monstanto crops contaminated by Monstanto crops are also being sued and asked to prove themselves innocent.
It's a travesty. I am not opposed to GM foods by any means, but this company's approach to solving problems with their products is completely unreasonable. A class-action suit seems to be the only answer.
If the GMO corn has been bred for high sugar, as we know that's the main focus, then the rats more than likely consumed more calories which I would expect to have a detrimental effect on most systems in the body. From the study: We note that these unrelated, different non-GM maize types were not shown to be substantially equivalent to the GMOs. The quantity of some sugars, ions, salts, and pesticide residues, do in fact differ from line to line, for example in the non-GM reference groups. This not only introduced unnecessary sources of variability but also increased considerably the number of rats fed a normal non-GM diet (320) compared to the GM-fed groups (80) per transformation event, which considerably unbalances the experimental design. A group consisting of the same number of animals fed a mixture of these test diets would have been a better and more appropriate control.
If you spray an insect with water containing soap you will kill it too, are you going to stop taking baths? Salt has some rather nasty effects on slugs, so you better get rid of that. Insects are different that humans.
why haven't they put it in a really major journal--Nature, Science, PNAS, or something like PlosONE if the whole publication really had to be open access?
Yeah, their editor-in-chief is only the chief of mammalian genetics at NIH, and their editorial board is a bunch of slackers from the likes of Georgeton, UCLA school of medicine, Mount Sinai School of Medicine, Vancerbilt, Nortwestern, UC, etc.
OK, I haven't read the paper in detail... Glancing at their results table, it doesn't seem clear cut overall. E.g. there are cases where rats fed 11% GM corn show a response, but rats fed 33% GM corn don't, cases where male rats are apparently affected, but not females, and vice versa. They also don't name the maize they used as a control, so we don't know how accurate it is. Maybe you should read it in detail. FTFA: The raw data have been obtained by European governments and made publically available for scrutiny and counter-evaluation. So, they didn't actually perform the experiments, they're using the results of experiments that others did. It doesn't invalidate your point, but if you read further, I think they realize this:Furthermore, groups of animals were also fed with diets containing one of six other normal (non-GM) reference maize lines; the same lines for the NK 603 and MON 810 tests, but different types for the MON 863 trials. We note that these unrelated, different non-GM maize types were not shown to be substantially equivalent to the GMOs. The quantity of some sugars, ions, salts, and pesticide residues, do in fact differ from line to line, for example in the non-GM reference groups. This not only introduced unnecessary sources of variability but also increased considerably the number of rats fed a normal non-GM diet (320) compared to the GM-fed groups (80) per transformation event, which considerably unbalances the experimental design.
Yeah, I know, actually reading the article before posting your critical analysis is pretty hard to avoid.
GM is an accelerated version of what happens in nature.
No it's not. It's the artificial manipulation of a genotype to get a desired trait by means that are not very well understood but that mostly work although their consequences are not very well grasped.
We need it to feed our billions.
No we don't. Crop rotation and the use of better seeds works much better and with far less pesticides and other toxic chemicals, notably in emerging markets.
However, a certain company won't get as rich if we go that way...

Selective breeding is not the same thing as modern genetic modification. Mendel wasn't putting bacterial genes into corn. We've had thousands of years of testing selective breeding. We have had a decade or so of testing bacteria protein laced corn and other genetically modified foods. See the difference? The damn hippies were right: we should have tested this stuff more.

I've seen this a lot on this site (unfortunately). Luddite is tossed around as a swear word to ridicule those who don't understand or see any benefits of modern tech. The opposite exists but we don't have a single word for it, people who automatically trust any new tech to be safe, without any evidence that it is safe, other than the inventor's and corporation's word for it. There's a word used that is close, but doesn't specify "as regards newer tech", that is a "pollyanna". We really need a new word for those who blindly "trust" but never "verify" all new high tech advances.
This issue with some of the GM corn mods has been known for years now, and dismissed by the big business sycophants/pollyannas. The largest misconception I have seen is equating *cross species modification* with naturally occurring or man made same species hybrids. These get equated all the freaking time by alleged tech savvy people as the excuse to just "trust". The "tech pollyannas" knee jerk automatically trust, based on a starting point of falsehood belief. It's just as loony and stupid as being a luddite based on erroneous or even zero knowledge of the subject.
I am a farmer and I will say I do NOT trust corporate big ag business (nor ag college academia that relies on the same big business for funding and has tame scientists in and out of the same big business) to be self regulating as to safety concerns nor do I trust the governmental regulators because of the revolving door "jobs" aspect that occur. (exactly the same as occurs with Wall Street/Federal Reserve/Treasury/SEC revolving door jobs). There's WAY too much money involved for there not to be corruption. Just human nature. Just because some person has many letters next to their name, or some official government title, is not any guarantee they are trustworthy as to being non corrupt or "bought off". They are just as likely or not as likely as anyone else, and as the currency units involved go up in number..we should take closer and closer looks as to this trust and verify business.
It would be nice to trust the system, but I can't the way it is set up now.
Here's an interesting video on this food subject, on how much trust we should place in huge global ag business and regulations as they exist now.

Look at software code. A chunk can be written, looked at, have other people look at it, vetted..few months later they missed something and there is an 0-day.
Well, that can be patched.
Can't say the same thing for food stuff once it is planted all over. Won't be any patches once it is out in the wild and air pollination starts spreading it. We are already seeing some of the first minor examples with canola/rapeseed "superweeds". Just wait until there are major examples.
It isn't a matter of if, it is a matter of when. There will be a hugemongous "whoops..heh heh heh, guess we missed that" excuse mumbling major screwup, by guys in black suits and white lab coats at some news conference, with the global food supply. This corn might be it, who knows, but it is coming.
Hmm did you hear the rest of the story on that one ?
They refused "free" gm crops seed and food, worked hand in hand with ONU to alleviate the food crisis and started sowing "normal" traditionnal seeds that were acclimated to their country.
And now they have almost reached food production independence.
Can you remind me what happened to the neighboring countries that accepted ?
They actually sowed some of the grains and now pay the "Monsanto Tax"...and even if short term they solved the problem, they now are in a problematic situation for years (possibly decades) to come.
Have a look at a documentary called "the world according to Monsanto" and what happened to some south american countries that are now paying millions, if not billions to Monsanto each year. Also have a look at Indian (like in India) cotton farmers and their suicide rates since they switched to GM cotton. One of the worst human tragedy of the decade, because they had to buy fertiliser and RoundUp, got more heavilly in debt and commited suicide when they couldn't repay it all.
And I'm not even a green activist. I just despise the bastards from Monsanto...
