Canadian researchers have allegedly detected the presence of Cry1Ab toxin in human blood, raising questions about whether “pesticides associated to genetically modified [GM] foods (PAGMF)” break down during digestion as previously claimed. Aziz Aris and Samuel Leblanc, “Maternal and fetal exposure to pesticides associated to genetically modified foods in Eastern Townships of Quebec, Canada,” Reproductive Toxicology, 2011. The study apparently focused on 30 pregnant and 39 non-pregnant women with no direct or indirect contact with pesticides. The findings evidently showed Cry1Ab toxin—“an insecticidal protein produced by the naturally occurring soil bacterium Bacillus thuringiensis [bt]” and used in GM maize—“in 93% and 80% of maternal and fetal blood samples, respectively and in 69% of tested blood samples from non-pregnant women.”
According to the study’s authors, these results suggest “(1) that these toxins may not be effectively eliminated in humans and (2) there may be a high risk of exposure through consumption of contaminated meat,” since Cry1Ab has also been discovered “in the gastrointestinal contents of livestock fed on GM corn.” Moreover, as the authors speculated, “given the widespread use of GM foods in the local daily diet (soybeans, corn, potatoes,…), it is conceivable thattherefore offered their research as a baseline for further nutrition, toxicology and reproductive studies, “particularly those using the placental transfer approach.” See India Today, May 11, 2011. the majority of the population is exposed through their daily diet.” They have
