Well argued, carefully referenced letter - very useful.

Dear Colleague,

Attached is the Independent Scientists' Letter provided for the 8th of April 2006 Joint International GMO Opposition Day (JIGMOD; see: ). This letter will officially be read during the planned international video-conference, and notably used at the related demonstrations (9th of April in Chicago, 20th of April in Brussels). It is aimed at parlementarians, and possibly at exercising an influence over the corporate shareholders of Biotech multinationals. It was mainly written by Professor Arpad Pusztai, and reviewed by anonymous contributors.

For the sake of accessibility to non-specialists, it comprises a synthetic easy-to-read text completed with more technical references. You may also notice that it is focused on the health dimension, to which our decision makers are more particularly sensitive.

Currently circulated among the scientists who are likely to co-sign it, this letter will be proposed for signature to the participating organizations.

If you wish to be one of the signatories, you may simply send us an email indicating your professional position and coordinates, at the following address: This email address is being protected from spambots. You need JavaScript enabled to view it.

With our best regards,
Dr Dominique Beroule, on behalf of the JIGMOD Coordinating Committee.

P.S. Could you please pass on this message to your circle, and spread the word over your grassroot contacts? Thank you in advance.


The current generation of genetically modified (GM) crops uneccessarily risks the health of the population and the environment. Present knowledge is not sufficient to safely and predictably modify the plant genome, and the risks of serious side-effects far outweigh the benefits. We urge you to stop feeding the products of this infant science to our population and ban the release of these crops into the environment where they can never be recalled.

The current technology was rushed to market long before the science was worked out. Its introduction was accompanied with rigged research, bribes,1 gagged scientists,2 cover-ups3 and regulatory agencies stacked with industry representatives.4 With mounting evidence of serious health and environmental problems, we must act quickly to end the charade and this dangerous abuse of public trust.

Current safety assessments are inadequate to catch most of the harmful effects. When a foreign gene is artificially inserted into a living organism such as a GM crop, the preexisting natural gene of the organism can unintentionally be deleted, switched off, permanently switched on, mutated or fragmented. Hundreds of natural genes may change the way they generate their proteins (basic molecules that form living cells), and even the newly introduced protein may differ from what was intended.

* Key assumptions used as the basis for safety claims have been overturned and several adverse findings suggest that GM foods are unsafe. GM-fed animals had problems with their growth, organ development and immune responsiveness, blood5 and liver cell6 formation, as well as damaged organs (bleeding stomachs,7 excessive cell growth,8 inflammation in lung tissue9), sterility problems10 and increased death rates,11 including among the offspring.12

* Risks are increased by the fact that the genes inserted into GM food not only survive digestion, but transfer into body organs and circulation. Transgenes have been found in the blood, liver, spleen and kidneys.13 DNA can even travel via the placenta into the unborn.14 The only human clinical trial showed that transgenes from soy transfer into intestinal bacteria.15

* Claims that no one has gotten hurt from GM foods are misleading, since no one monitors human health impacts. We do know that soya allergies skyrocketed by 50 percent after GM soybeans were imported to the UK,16 and a GM food supplement killed about 100 Americans and caused 5,000- 10,000 to fall sick.17

* Some GM crops create their own pesticide called Bt. Their approval relied on the assumption that Bttoxin is not bioactive in mammals. But Bt-toxin caused powerful immune responses and abnormal and excessive cell growth in mice. Filipinos living next to Bt cornfields developed mysterious symptoms during the time of pollination - three seasons in a row - and blood tests showed an immune response to Bt.18 A November 2005 report from India claims that Bt cotton also creates allergic responses.19 What if Bt genes transfer to gut bacteria like soya genes do? They could turn our internal flora into living pesticide factories.

Despite the Public Relation spin, GM crops increase the use of herbicides20, lower average yield, and endanger food security. They are detrimental to sustainable and organic farming, and trap farmers in a cycle of indebtedness and dependence. They endanger biodiversity21, harm beneficial insects22, damage soil bacteria23, contaminate non-GM varieties24 and may persist in the environment for generations.25

Insurance companies do not want to cover the risks inherent in GMOs.26 Consumers do not want them.27

Please act today to protect our health, our environment, and future generations.
