Toxicology Results on Pigs Fed Genetically Modified Soy and Maize

A study testing pigs fed a diet of genetically engineered soy and corn over a 22.7 week period showed a significant increase in severe stomach inflammation compared to those fed non-GMO diets. Inflammation in GMO fed males compared to their non-GMO fed counterparts multiplied by a factor of 4, in females by a factor of 2.2. The GMO fed pigs also had a 25% heavier uteri than their non-GMO fed counterparts. The lead researcher, Dr. Judy Carman, is an epidemiologist, biochemist, and director of the Institute of Health and Environmental Research in Kensington Park, Australia. The study can be seen in the most recent publishing of the Journal of Organic Systems.

The abstract states:

“A significant number of genetically modified (GM) crops have been approved to enter human food and animal feed since 1996, including crops containing several GM genes ‘stacked’ into the one plant. We randomized and fed isowean pigs (N=168) either a mixed GM soy and GM corn (maize) diet (N=84) or an equivalent non-GM diet (N=84) in a longterm toxicology study of 22.7 weeks (the normal lifespan of a commercial pig from weaning to slaughter). Equal numbers of male and female pigs were present in each group. The GM corn contained double and triple-stacked varieties. Feed intake, weight gain, mortality and blood biochemistry were measured. Organ weights and pathology were determined post-mortem. There were no differences between pigs fed the GM and non-GM diets for feed intake, weight gain, mortality, and routine blood biochemistry measurements. The GM diet was associated with gastric and uterine differences in pigs. GM-fed pigs had uteri that were 25% heavier than non-GM fed pigs (p=0.025). GM-fed pigs had a higher rate of severe stomach inflammation with a rate of 32% of GM-fed pigs compared to 12% of non-GM-fed pigs (p=0.004). The severe stomach inflammation was worse in GM-fed males compared to non-GM fed males by a factor of 4.0 (p=0.041), and GM-fed females compared to non-GM fed females by a factor of 2.2 (p=0.034).”

Researchers said more long-term feeding studies need to be done.
