THE MOST WIDELY USED HERBICIDE IN THE WORLD CONTAINS COMPOUNDS MORE TOXIC THAN DECLARED (1) |
|
|
|
Caen, Feb. 21st, 2013 - In a new research published in the high ranked scientific journal Toxicology, Robin Mesnage, Benoît Bernay and Professor Gilles-Eric Séralini, from the University of Caen, France, have proven (from a study of nine Roundup-like herbicides) that the most toxic compound is not glyphosate, which is the substance the most assessed by regulatory authorities, but a compound that is not always listed on the label, called POE-15. Modern methods were applied at the cellular level (on three human cell lines), and mass spectrometry (studies on the nature of molecules). This allowed the researchers to identify and analyse the effects of these compounds.
Context: Glyphosate is supposed to be the "active ingredient" of Roundup, the most widely used herbicide in the world, and it is present in a large group of Roundup-like herbicides. It has been safety tested on mammals for the purposes of regulatory risk assessment. But the commercial formulations of these pesticides as they are sold and used contain added ingredients (adjuvants). These are often classified confidential and described as “inerts”. However, they help to stabilize the chemical compound glyphosate and help it to penetrate plants, in the manner of corrosive detergents. The formulated herbicides (including Roundup) can affect all living cells, especially human cells. This danger is overlooked because glyphosate and Roundup are treated as the same by industry and regulators on long-term studies. The supposed non-toxicity of glyphosate serves as a basis for the commercial release of Roundup. The health and environmental agencies and pesticide companies assess the long-term effects on mammals of glyphosate alone, and not the full formulation. The details of this regulatory assessment are jealously kept confidential by companies like Monsanto and health and environmental agencies.
Conclusion and consequences: This study demonstrates that all the glyphosate-based herbicides tested are more toxic than glyphosate alone, and explains why. Thus their regulatory assessments and the maximum residue levels authorized in the environment, food, and feed, are erroneous. A drink (such as tap water contaminated by Roundup residues) or a food made with a Roundup tolerant GMO (like a transgenic soya or corn) were already demonstrated as toxic in the recent rat feeding study (2) from Prof. Séralini team. The researchers have also published responses to critics of the study (3). This new research explains and confirms the scientific results of the rat feeding study. Overall, it is a great matter of concern for public health. First, all authorizations of Roundup-type herbicides have to be questioned urgently. Second, the regulatory assessment rules have to be fully revised. They should be analyzed in a transparent and contradictory manner by the scientific community. Agencies that give opinions to government authorities, in common with the pesticide companies generally conclude safety. The agencies’ opinions are wrong because they are made on the basis of lax assessments and much of the industry data is kept confidential, meaning that a full and transparent assessment cannot be carried out. These assessments are therefore neither neutral nor independent. They should as a first step make public on the Internet all the data that underpin the commercial release and positive opinions on the use of Roundup and similar products. The industry toxicological data must be legally made public. Adjuvants of the POE-15 family (polyethoxylated tallowamine) have now been revealed as actively toxic to human cells, and must be regulated as such. The complete formulations must be tested in long-term toxicity studies and the results taken into account in regulatory assessments. The regulatory authorisation process for pesticides released into the environment and sold in stores must urgently be revised. Moreover, since the toxic confidential adjuvants are in general use in pesticide formulations, we fear according to these discoveries that the toxicity of all pesticides has been very significantly underestimated.
This study was conducted in the University of Caen with the structural support of CRIIGEN in the European Network of Scientists for Social and Environmental Responsibility (ENSSER www.ensser.org).

CRIIGEN press conference on the study of Prof. Séralini's group – INVITATION FOLLOWS AT THE EUROPEAN PARLIAMENT TOXICITY CONFIRMED FOR A GMO AND THE PESTICIDE ROUNDUP COMPLAINTS OF DEFAMATION AGAINST CRITICS Raw data released to a notary CRIIGEN welcomes the confirmation of the research of Prof. Séralini's group on the long-term toxicity of Roundup, the most widely used herbicide in the world, and of a genetically modified (GM) maize which absorbs it without being killed. Both are products of Monsanto Company. This study has become one of the most frequently accessed in the world since it was published in September 2012 (Food and Chemical Toxicology, 50 (2012), 4221-4231). The journal, one of the best toxicological journals, did not retract the study, despite relentless pressure to do so. Now it has published Séralini's group’s detailed answers to critics (Food and Chemical Toxicology, 2013, online). The group has new experimental data on Roundup, which will soon be released. Negative criticisms came from around 40 scientists or groups, including agencies responsible for GMO or pesticide authorisations. Most were subsequently revealed to have conflicts of interest, either directly with Monsanto Company, or with other commercial interests, or with bodies that had previously authorized the commercialization of these or similar products [i]. Most are not specialists in the areas of pesticide toxicology or GMO risk assessment and do not publish papers on these topics. CRIIGEN and the research team have received statements of support and positive comments from more than 300 scientists from 33 countries across five continents. In our opinion these scientists are more representative of the scientific community at large. CRIIGEN also welcomes the fact that the French food safety agency ANSES and several countries, including France, have recognized that long-term tests on GMOs are needed and that of the toxicity of pesticides has been underestimated. A project in this direction has been submitted to the French Parliament. In addition, the Directorate General for Health and Consumers of the European Commission has disavowed EFSA's opinion on the lack of necessity of long term toxicity testing [ii]. Séralini's study revealed the laxity of assessment which has allowed the commercialization of such products, on the part of agencies including EFSA. Their serious professional misconducts could endanger public health and lives. Séralini's team and CRIIGEN have just filed complaints of defamation against claims of "fraud" and "falsified data" that were respectively published in "Marianne" and "La Provence" by Jean-Claude Jaillette and Claude Allègre who is a member of the French association for plant biotechnologies (AFBV). AFBV and its president Marc Fellous was convicted of defamation against Séralini’s team in 2011. Other complaints of defamation are in process. In 2013 we will launch other legal actions to force disclosure of hidden and poor quality toxicological data. These data were used by the regulatory agencies to enable the commercial release of the products that we tested, among others. To set an example, we are arranging the formal delivery of the raw data of our last study to a notary. We will make these public as soon as the regulatory agencies or Monsanto do the same for their data, or when governments consent to publish the industry data. Thus the scientific community will have full access to all the data on these industrial products. This will enable a true assessment, contradictory and transparent, and not a pseudo-assessment distorted by lobbies that are more concerned with protecting their own interests than with public health.

Answer to EFSA's regarding risk assessment |
|
|
|
EFSA suggests harmonised default values for use in risk assessment http://www.efsa.europa.eu/en/press/news/120307a.htm
We have some criticisms concerning the harmonised default values suggested by EFSA: First, the extrapolation of the exposure time. Using an uncertainty factor out of two factors implies that the effects are simply regarded as duplicated from a subchronic to a chronic study. This operation does not take into account the specific effects of chronic periods such as hormonal effects that may appear in the range of nanomolar or even less. Here, no factor is applicable because we can not foresee what may happen. Secondly, reducing the uncertainty factor of 100 to specific factors when knowing the toxicokinetic or toxicodynamic characteristics of a compound seems unjustifed. It is less cautious. Thirdly, there is only one adult category. It still lacks some subpopulation such as pregnant women who at present are "treated" like men weighing an average of 70 kg. Factors to convert a dietary dose to a physiological dose appear to be correct and the idea of using Benchmark doses to be more accurate than a LOAEL seems interesting. It avoids the uncertainty associated with the choice of experimental doses, but it must not fall into the trap of linear dose response paradigms. |

Report and answers to criticisms from biotech lobbies - April 2012 |

The conference tour in Australia and Phillipines of Prof. Gilles-Eric Séralini and Chef Jérôme Douzelet (see pictures http://www.flickr.com/photos/79123951@N07/sets/72157629830513273/ ) was appreciated and acknowledeged in the Universities of Sydney, Canberra, Adelaïde, Perth, and Los Banos (next to Manilla), and in front of the public or cooks in Sydney, Perth, Margaret River, Manilla. Several radio or press interviews were performed together with meetings with politicians. A contradictory debate in the ABC australian radio with the Chief Scientist of FSANZ (the Australian and New Zealand regulatory authority for GMOs) is available (see link http://www.abc.net.au/radionational/programs/latenightlive/are-gmos-safe3f/3858030). The conferences were in particular on the poor assessments and the risks of transgenic wheat and brinjal requested for cultures over there. Criticisms were numerous since big economical issues are the goal for biotech companies. These criticisms are not surprisingly those already made by biotech companies and their defenders already convicted of defamation against Prof. Séralini. These pseudo-scientific judge details regularly of his resume, awards, but do not bother read his scientific international peer-reviewed studies that support the purpose of his lectures. These are available upon request at

The food and health agencies like FSANZ in Australia or FDA in the United States, or EFSA in Europe, where these lobbies stand as demonstrated by numerous journalists, only publish opinions on websites. This is not enough to reach the international scientific community that, by contrast, congratulates Prof. Séralini on a regular basis. However these so-called independent agencies wait for health scandals to react and proofs by deaths (3000 for the Mediator drug authorized by this kind of agencies). Then, they can to some extent take evidence into account and alerts that often so against the business interests that they seem to serve. On another hand more than 1200 researchers from 30 countries have defended science transparency and scientific controversies in the defamation trial won by Prof. Séralini in the Court affair that opposed him to M. Fellous, who lost the case. Finally those who criticize the supposed links between Prof. Séralini and the « business homeopathic » certainly did not read the studies where this researcher tested in fact plant extracts in a non homeopathic manner on cell detoxification. Stupidity is rife in countries where GMOs or dollars try to be kings. |

Genetically engineered maize: New indication of health risks - January 2012 |
|
|
|
Bt protein toxic to human cells Caen/ München. Insecticidal Bt toxins such as those produced in genetically engineered plants can be detrimental to human cells. This is a result of recent research led by researchers at the University of Caen (France). Their experiments showed that toxins produced in, for example, the genetically engineered maize MON810, can significantly impact the viability of human cells. The effects were observed with relatively high concentrations of the toxins, nevertheless there is cause for concern. According to companies like Monsanto, which produces genetically engineered maize with these toxins, the toxins are supposed to be active only against particular insects and should have no effect on mammals and humans at all. For the first time, experiments have now shown that they can have an effect on human cells. These kinds of investigations are not a requirement for risk assessment in Europe or in any other region. Another finding of the researchers concerns a herbicide formulation sold under the brand name Roundup. Massive amounts of this herbicide are sprayed on genetically engineered soybean crops and its residues can be found in food and feed. According to the new publication, even extremely low dosages of Roundup (glyphosate formulations) can damage human cells. These findings are in accordance with several other investigations highlighting unexpected health risks associated with glyphosate preparations. |

Controversy on GMO's health effects |
|
|
|
A recent article (Snell Chelsea et al., Food and Chem. Tox.) provokes debate in December 2011. It was co-signed by Gérard Pascal who has contributed to allow the authorization of a large number of GMOs in french regulatory authorities. After reviewing - that is what he said - twenty-four long-term or over several generation studies, Gérard Pascal pretends that the latter demonstrate that GMOs in food are safe. Of course, this gentleman obediently produces the results of the manufacturers explaining that all significant effects compared to controls are not a problem as they are included within the "normal biological variation." So what is the point of having controls in an experiment then ? He does not carry out the statistics again, unlike we did. The authors qualifie as "long term" tests conducted over a few months on salmon or macaques, over two years on cows that live fifteen years, and that only lasted for a few weeks on chickens or quails, and they did not notice either that all these studies were not requested before the commercialization of the GMOs in question. Our reviews largely consulted by the scientific community (Séralini et al. Env. Sci. Europe, 2011, 23, 10-20, see the link on our website in the welcome page) detailing the contrary are ignored, which is not at all ethical from a scientific point of view. Never mind the subjectivity! Worse, the large number of long-term studies by Malatesta and colleagues on mice eating soybeans with Roundup, that we had already identified as highlighting the negative effects of GMOs (in depths liver, pancreatic, testicular cell disorders) are considered as showing nothing to the despair of the authors in their conclusion! They re-judge international publications as they pleas, transform the findings or ignore them for very dubious or misleading reasons like: "the GM soy might not have grown next to a field non-GMO control before being eaten by mice!" When one is concerned by such matters instead of thinking about public health, isn’t there a risk of creating generations of students who will be ashamed of science? A perfect "stage" for contradictory expertise ! |

Studies show animals fed on GM diet face organ problems |
|
|
|
A new report reviewing 19 studies of mammals fed with commercialized GM soybean and maize (which represent more than 80% of all GMOs grown on a large scale) indicates liver and kidney signs of toxicity in mammals fed on a GM diet. The report by Gilles-Eric Séralini et al is published in Environmental Sciences Europe (2011, 23, 10-20). The authors studied data from biotech companies from 90-day-long feeding tests on rats that include biochemical blood and urine parameters of mammals eating GMOs modified for herbicide tolerance and insecticide production. The tests were conducted as a result of court actions or official requests and the authors reviewed the studies in the scientific literature. Though the tests may not point to chronic toxicity of GMOs since the 90 day period is too short, the authors nonetheless cautioned that the signs highlighted in the kidneys and livers could spell the onset of chronic diseases: on a total of 9% of disturbed parameters, 43% are concentrated in the kidneys of the male rats. The researchers suggested that more detailed and prolonged studies should be conducted. They underlined that since no minimal length for the tests is yet compulsory for any of the GMOs cultivated on a large scale, it was socially unacceptable in terms of consumer health. The authors also suggested an alternative to conventional feeding trials, to understand the biological significance of statistical differences. This approach will make it possible to avoid both false negative and false positive results, in order to improve safety assessments of agricultural GMOs before their commercialization for cultivation for food and feed as well as for imports. This is the most comprehensive review on this topic to date. The full paper is available at: http://www.enveurope.com/content/23/1/10 |

CRIIGEN is filing a complaint ! May 20th 2011 |

CRIIGEN is filing a complaint against Marc Fellous and the AFBV for forgery and use of forgeryCRIIGEN and Prof. Gilles-Eric SERALINI have submitted a complaint to the Public Prosecutor of Paris on May 20th 2011, for forgery and the use of forgery in relation to a document that was produced in Court by Prof. Marc FELLOUS and the AFBV (Association Française des Biotechnologies Végétales), during a trial at the end of which Marc FELLOUS was convicted of defamation against Gilles-Éric SERALINI, on January 18th 2011. The plaintiffs are shocked by such attitudes, especially since the declarations of the AFBV defamatory letters were pretending to react to the dissemination of “false information” and “stretching of the rules of scientific neutrality”. Furthermore, during the defamation trial that was won by Prof. SERALINI, a connection was established between the AFBV and the biotechnology firms. CRIIGEN and Prof. Gilles-Eric SERALINI would like to thank very warmly the more than 1100 scientists of 35 different countries who expressed their support, as well as about 12,000 citizens, and the Fondation Sciences Citoyennes, the European Network of Scientists for Social and Environmental Responsibility ENSSER and many other societies, foundations and organizations. These people have signed a petition in favour of a healthy and contradictory debate, beyond lies, disgraceful acts, and biased interests that tread on health and environment risk studies, mostly where agricultural GMOs and pesticides are concerned.

detoxification of human cells - April 2011 |
|
|
|
TO PREVENT THE EFFECTS OF POLLUTANTS AND TO DETOXIFY OUR CELLS: IT IS POSSIBLE ! Prof. Seralini's group in the University of Caen and CRIIGEN (www.criigen.org) demonstrate the negative effects of common pollutants (the herbicides Roundup or Atrazine, the plasticizer BisphenolA) on human cells. Extracts of organic plants in precise combinations are rapidly able to prevent or cure at least in part these cellular effects. These have been made by Sevene Pharma Company. This work opens the door of a new ecomedicine, which does not avoid a stronger regulation of pesticides and other pollutants. Contact:
