As a precondition to buy seeds, either to plant for crops or to use in research study, Monsanto and the gene giant companies must first sign an End User Agreement with the company. For the past decade, the period when the greatest proliferation of GMO seeds in agriculture has taken place, Monsanto, Pioneer (DuPont) and Syngenta require anyone buying their GMO seeds to sign an agreement that explicitly forbids that the seeds be used for any independent research. Scientists are prohibited from testing a seed to explore under what conditions it flourishes or even fails. They cannot compare any characteristics of the GMO seed with any other GMO or non-GMO seeds from another company. Most alarming, they are prohibited from examining whether the genetically modified crops lead to unintended side-effects either in the environment or in animals or humans.
The only research which is permitted to be published in reputable scientific peer-reviewed journals are studies which have been pre-approved by Monsanto and the other industry GMO firms.
In the United States a group of twenty four leading university corn insect scientists have written to the US Government Environmental Protection Agency demanding the EPA force a change to the company censorship practice. It is as if Chevrolet or Tata Motors or Fiat tried to censor comparative crash tests of their cars in Consumer Reports or a comparable consumer publication because they did not like the test results. Only this deals with the human and animal food chain. The scientists rightly argue to EPA that food safety and environment protection "depend on making plant products available to regular scientific scrutiny." We should think twice before we eat that next box of American breakfast cereal if the corn used is GMO .
