Professor Parrott gives GE-fed pig study an F

The following is an edited excerpt.

Paper: GE-fed pigs have irritated stomachs and thicker uteruses

Grade: F

Why does this article fail?

In this study, pigs were fed GM or nonGM diets for almost 23 weeks. At the end of the study, the pigs were weighed. Blood chemistry was analyzed, and organ weights were measured. Weight gains and all body statistics were the same for both groups of pigs, but “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).”

Aside from the fact that it is not evident how pigs with severe stomach inflammation could have the same weight gain as pigs with no stomach inflammation, and aside from the fact that commercial pig slaughter houses have not found the same differences, the paper has several other limitations.
