Consumers Union endorses study showing significant negative effects in pigs fed GMO crops
by Larry Geller
The new peer-reviewed long-term pig feeding study just published raises important concerns about possible health impacts of consuming genetically engineered (GE) corn and soy. There have been very few animal feeding studies of GE food to date, and extremely few that lasted longer than 90 days. This new study looked at pigs fed GE corn and soy under commercial production conditions over a 22.7 week period. Compared to a control group that was fed conventional corn and soy, the GE-fed pigs showed significant increases in severe stomach inflammation and thickening of the uterus. The study in online here: http://www.organic-systems.org/journal/81/8106.pdf.
The study found that the uteri of GE-fed pigs was significantly larger (weighed 25 percent more) than those of non-GE-fed pigs. In addition, the rate of severe stomach inflammation was more than 2.5-fold higher, on average, for GE-fed pigs compared to non-GE-fed pigs (32 percent vs. 12 percent, respectively). Indeed, for male pigs, the rate of severe stomach inflammation was four times higher for GE-fed males to non-GE fed males, and for females, the rate was more than 2-fold higher.

Consumers Union quoted the authors of the study who indicate that there should be long-term animal studies to identify potential toxicological and reproductive effects of GM crops.
