Paper: Histopathological Investigation of the Stomach of Rats Fed a 60% Genetically Modified Corn Diet

By Irena M. Zdziarski, Judy A. Carman, John W. Edwards

The paper provides evidence from a feeding experiment on rats that the authors did, that GM crops producing Cry proteins (sometimes known as Bt proteins), may not be as safe as asserted. The authors saw damage to the stomach when it was looked at under regular and specialised microscopes. These crops can also be called insect-resistant crops or Bt crops.
