French scientist Gilles-Eric Séralini unmasked the dangers of genetically modified brinjal, almost approved for commercial production in India. He shared with Savvy Soumya Misra his findings on Bt brinjal and Roundup Ready soybean

On the data submitted on Bt brinjal by Mahyco for approval from the Indian government

The data submitted to the Genetic Engineering Approval Committee (geac) of the Union environment ministry is not valid; it has not been signed by the scientist who conducted the tests. What is more scandalous is that the studies on the effects of Bt brinjal were conducted for just three months.     

If the product is to be consumed by humans, the tests should have been for a period of at least two years-the lifespan of a rodent.

Worse, Mahyco tried to cover up the side-effects by jumbling data on various types of brinjal in a way that it was hard to compare Bt brinjal with normal brinjal. I am sorry to say people in the geac did not carefully assess the data. It is also not clear how the geac overlooked the fact that Bt brinjal has a protein that induces resistance to antibiotics. Mahyco has not studied hormonal impacts of Bt brinjal-Bt toxin found in it could lead to reproductive health problems.

On his findings on Roundup Ready soybean that tolerates herbicides

Our study found that even minute doses of Roundup (a natural herbicide) disrupt sex hormones like androgen and estrogen. The inert ingredients in Roundup Ready (RR) soybean like polyethoxylated tallowamine kill human cells and disrupt the synthesis and action of human sex hormones. The research was published in this year’s July edition of the journal Toxicology. Some pregnant women who consumed RR soybean developed disorders. This combined with certain studies on animals in labs (conducted by others) made us conclude that Roundup is an endocrine disruptor.

On claims that GM plants reduce the need for pesticides

This is a false projection. Bt plants, in fact, are designed to produce toxins to repel pests. Bt brinjal produces a very high quantity of 16-17mg toxin per kg. They affect animals. Unfortunately, tests to ascertain their effect on humans have not been conducted. RR soybean that makes up 63 per cent of GM plants in the world contains high amounts of Roundup. The US food and drug administration (usfda) has allowed up to 400 ppm Roundup residues in animal feed. It is much more than what we recommended. There was a paper published in June in Scientific American saying usfda would review the approval accorded to RR soybean because of our study.
