All Guinea Pigs: Severe toxic effects of a GMO and of the major herbicide of the world

Published on CRIIGEN, (also as PDF, September 2012).

For the first time, the health impact of a GMO and a widely used pesticide have been comprehensively assessed * in a long term animal feeding trial of greater duration and with more detailed analyses than any previous studies, by environmental and food agencies, governments, industries or researchers institutes.  

The two tested products are in very common use : (i) a transgenic maize made tolerant to Roundup, the characteristic shared by over 80% of food and animal feed GMOs, and (ii) Roundup itself, the most widely used herbicide on the planet. The regulatory approval process requires these products to be tested on rats as a surrogate for humans.

The new research took the form of a two year feeding trial on 200 rats, monitored for outcomes against more than 100 parameters. The doses were consistent with typical dietary/ environmental exposure (from 11% GMO in the diet, and 0.1 ppb in water).

The results, which are of serious concern, included increased and more rapid mortality, coupled with hormonal non linear and sex related effects. Females developed significant and numerous mammary tumours, pituitary and kidney problems. Males died mostly from severe hepatorenal chronic deficiencies. Professor Seralini’s team in the University of Caen is publishing this detailed study in one of the leading scientific international peer-reviewed journals of food toxicology, on line on Sept. 19, 2012 … //

… In the meantime, labelling of all GMOs in the feed/food should be mandatory, including livestock products from animals that have been fed GMO’s. Finally, the nature of all compounds present in pesticide formulations should be made public.
