Dear friends and colleagues
Re: Long-term toxicology study on pigs fed a combined GM soy and GM maize diet
New research published in the Journal of Organic Systems raises serious questions over the long-term health impacts of GM food and feed. In a long-term toxicology study, pigs were fed over 22.7 weeks (the normal lifespan of a commercial pig from weaning to slaughter) on a mixture of GM soy and GM corn, and compared to pigs fed an equivalent non-GM diet.
The GM diet was associated with gastric and uterine differences in pigs. GM-fed females had on average a 25% heavier uterus than non-GM-fed females, a possible indicator of disease that requires further investigation. The level of severe inflammation in stomachs was markedly higher in pigs fed on the GM diet. Male pigs were more strongly affected.
For some years now farmers and veterinarians have reported reproductive and digestive problems in pigs fed on a diet containing GM soy and corn. The study lends scientific credibility to the anecdotal evidence.
The results also provide clear evidence that regulators need to assess GM crops containing mixtures of GM genes, regardless of whether those genes occur in the one GM plant or in a mixture of GM plants eaten in the same meal, even if regulators have already assessed GM plants containing single GM genes in the mixture.
