We summarize the major points of international debate on health risk studies for the main commercialized edible GMOs. These GMOs are soy, maize and oilseed rape designed to contain new pesticide residues since they have been modified to be herbicide-tolerant (mostly to Roundup) or to produce mutated Bt toxins. The debated alimentary chronic risks may come from unpredictable insertional mutagenesis effects, metabolic effects, or from the new pesticide residues. The most detailed regulatory tests on the GMOs are three-month long feeding trials of laboratory rats, which are biochemically assessed. The tests are not compulsory, and are not independently conducted. The test data and the corresponding results are kept in secret by the companies. Our previous analyses of regulatory raw data at these levels, taking the representative examples of three GM maize NK 603, MON 810, and MON 863 led us to conclude that hepatorenal toxicities were possible, and that longer testing was necessary.
... As a conclusion, we call for the promotion of transparent, independent and reproducible health studies for new commercial products, the dissemination of which implies consequences on a large scale. Lifetime studies for laboratory animals consuming GMOs must be performed, by contrast to what is done today, like the two-year long tests on rats for some pesticides or some drugs.
Health risk assessment of genetically modified organisms (GMOs) cultivated for food or feed is under debate throughout the world, and very little data have been published on mid- or long-term toxicological studies with mammals. One of these studies performed under the responsibility of Monsanto Company with a transgenic corn MON863 has been subjected to questions from regulatory reviewers in Europe, where it was finally approved in 2005. This necessitated a new assessment of kidney pathological findings, and the results remained controversial. An Appeal Court action in Germany (Münster) allowed public access in June 2005 to all the crude data from this 90-day rat-feeding study. We independently re-analyzed these data.
Our analysis clearly reveals for the 3 GMOs new side effects linked with GM maize consumption, which were sex- and often dose-dependent. Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn. In addition, unintended direct or indirect metabolic consequences of the genetic modification cannot be excluded.
Duodenum of control (e) and GM-fed (f) mice; Alcian blue pH 2.5 staining for detection of acidic mucins: note the lower amount in the GM-fed mouse. Duodenum of control (g) and GM-fed (h) mice; high iron diamine-alcian blue technique for detection of sulpho-mucins: note the lower amount in the GM-fed mouse. Bars: 50 µm; insets 0.5 µm.
The GMO Panel notes that several of its fundamental statistical criticisms (EFSA, 2007a,b) of the authors' earlier study (Seralini et al., 2007) of maize MON863 are also applicable to the new paper by de Vendômois et al. In the GMO Panel's extensive evaluation of Seralini et al. (2007), reasons for the apparent excess of significant differences found for MON863 (8%) were given and it was shown that this raised no safety concerns.
The GMO Panel considers that de Vendômois et al.: (1) make erroneous statements concerning the use of reference varieties to provide estimates of variability that allow equivalence testing to place statistically significant results into biological context as advocated by EFSA (2008, 2009a); (2) do not use the available information concerning normal background variability between animals fed with different diets, to place observed differences into biological context; (3) do not present results using their False Discovery Rate methodology in a meaningful way; (4) give no evidence to relate well known gender differences in response to diet to claims of effects due to the respective GMOs; (5) estimate statistical power based on inappropriate analyses and magnitudes of difference.
In the absence of any indications that the observed differences in test parameters are indicative of adverse effects, the GMO Panel does not consider that the publication by Séralini et al. (2007) raises new issues which are toxicologically relevant.
Our results demonstrate that controls and GM-soybean fed mice are similarly affected by ageing. Moreover, the GM soybean-containing diet does not induce structural alterations in duodenal and colonic epithelium or in coliform population, even after a long term intake.

She has held a number of international positions, notably as the "Chair of the Codex Alimentarius Committee on General Principles in 2001 and 2002, as well as Deputy Director of the French Department of International Trade from 1998 to 2000, managing French food aid. Here she worked closely with the European Commission and several other international organisations, working to promote the European agricultural model.
Press Release 14 January 2013 EFSA is today announcing the launch of a major initiative designed to facilitate access to data, enhancing transparency in risk assessment. The programme, to be developed in cooperation with the Authority’s partners and stakeholders, will consider how best and to what extent technical data used in risk assessments can be made available to the broader scientific community and interested parties.
EFSA Executive Director Catherine Geslain-Lanéelle said: "Risk assessment is an evolving science and EFSA is always willing to review its past work should new robust science bring a new perspective to any of the Authority's previous findings. With the launch of today's initiative that aims to make data used in risk assessment publicly available, EFSA will help scientists from different areas of expertise develop research that can ultimately enrich academic literature and provide valuable new perspectives that can be included in risk assessments. This will make the conclusions of risk assessments even stronger when ensuring public health protection and further build confidence in EFSA's work."

Because we got tired of living in caves?
Oh, and "risk assessment is an evolving science" -- seems like "science" evolves behind evolution/adaptation. Why try to intervene in the first place?

It's about moving forward.
Caves were nice and safe. Why leave them?

Ok, avoid answering the issues, though I wish you would try to debate and argue the links I presented.
You think I haven't been clear enough? Ok, I'll try to remedy that.
Phage, I really don't understand your platform and beliefs on this issue after I am giving you some good (imo) information to digest.

I also do good bit of reading on a wide variety of topics including many science journals and as I stated I don’t always understand the finer details within them I do get the gist of them.
I will only attempt to answer this question from your post.

This is my understanding. There is a need for crops that are resistant to drought, disease, insects, and can increase yield. Maybe it isn’t as much of a problem here in the US but there are many other countries that would welcome such innovation. They may be able to modify plants to grow in conditions on lands that had been considered unfit for agriculture. I have traveled to several countries that had lands unfit for any crops and the populace would benefit greatly from such innovation. There are many reasons to intervene.
Your question got me interested if you could will you please tell me what you thought they were intervening for? What do you think their reasons are? Of course the company is profit driven however they wouldn’t be able to make profits if their product was not sought after. So basically I am asking for your opinion besides the obvious answer of money. Money will always be involved in selling any product.

Seralini? You know that he is rather notorious for the lack of rigor in his experimental methods, statistical "creativity", and interpretation, right?

And you know this how? Are you an agronomist?
It seems obvious to me that the larger the field you're dealing with, the more difficult it becomes to deal with pests.
But you're right, if it could be done it would be much more expensive. That's why the difference in the cost of organic produce. It costs more to farm that way.

Doesn't really sound very useful to all the rest of us, only useful to the farmers and Monsanto and that's about it.

I have seen no convincing evidence that there is anything inherently dangerous about permitted GMO crops.
I have no reason to think that there is anything inherently dangerous about GMO crops.
I don't understand why you think statements from the EFSA regarding their willingness to re-examine their data and an active program to increase transparency indicates that there is anything inherently dangerous about GMO crops.

No I haven't seen them.
Have you seen, or know where I can find all of the monsanto studies done for their products?
The NIH site is a clearinghouse for articles. It doesn't take much to have a paper put there. The differences in Seralini's results have to do with his questionable experimental methods, "creative" statistical analysis, and generally biased conclusions. And those aren't just my opinions.
And for his findings to be on NIH makes me wonder why their results differ from other's results.
Perhaps you can show me where you read this because I am reading the exact opposite.
As pointed out, the decrease exceeds the increase in herbicide use. A substantial net reduction.
Can you show me this fact? From what I read in the paper I linked shows an increase in chemicals not a decrease.
But fact is there was a net decrease in the net per acre application rate between 1996 and 2011.
The increased use of chemicals with the use of GMO crops has lead to an acceleration in these chemical resistant pests. This problem has become much worse with the use of GMO which has lead to an ever increasing use of more chemicals. The point here is the increased need and use of chemicals to combat chemical resistant pests not where the problem originated.
A new problem that started with the use of herbicides and pesticides, not with the use of GMOs.
Of course there hasn’t been an increase in the use of 2,4-D because there are currently restrictions on this herbicide and Dow has yet to get approval for the use of 2,4-D corn. One doesn’t need a study to predict an increase in the use of 2,4-D with the acceptance of Dow’s 2,4-D resistant corn.
And yet, as the data from your first citation shows, the use of 2,4-D declined by 17% between 1996 and 2011. There was an increase of 4% from 2005 to 2009 and no change from 2009 to 2011.
you confuse “speculation” with hypothesis. The summary of that paper is predicting an increase in chemical use based on current trends which is hardly speculation. It also predicts an increase in the use of 2,4-D with the introduction of 2,4-D resistant corn.
Is a statement of speculation. Speculation about deregulation. Speculation about what the situation would be without GMOs. Speculation that 2,4-D is and will remain the only alternative.
