Toxin from GM crops found in human blood: Study


Scientists from the University of Sherbrooke, Canada, have detected the insecticidal protein, Cry1Ab, circulating in the blood of pregnant as well as non-pregnant women.

They have also detected the toxin in fetal blood, implying it could pass on to the next generation. The research paper has been peer-reviewed and accepted for publication in the journal Reproductive Toxicology. The study covered 30 pregnant women and 39 women who had come for tubectomy at the Centre Hospitalier Universitaire de Sherbrooke (CHUS) in Quebec.

None of them had worked or lived with a spouse working in contact with pesticides.

They were all consuming typical Canadian diet that included GM foods such as soybeans, corn and potatoes. Blood samples were taken before delivery for pregnant women and at tubal ligation for non-pregnant women. Umbilical cord blood sampling was done after birth.

Cry1Ab toxin was detected in 93 per cent and 80 per cent of maternal and fetal blood samples, respectively and in 69 per cent of tested blood samples from non-pregnant women. Earlier studies had found trace amounts of the Cry1Ab toxin in gastrointestinal contents of livestock fed on GM corn. This gave rise to fears that the toxins may not be effectively eliminated in humans and there may be a high risk of exposure through consumption of contaminated meat.

"Generated data will help regulatory agencies responsible for the protection of human health to make better decisions", noted researchers Aziz Aris and Samuel Leblanc.

Given the potential toxicity of these environmental pollutants and the fragility of the foetus, more studies are needed, particularly those using the placental transfer approach, they added Experts have warned of serious implications for India. Cottonseed oil is made from seeds of genetically modified cotton and thus Bt toxin may have already entered the food chain in India.
