Troubling GMO history shows it’s bad science

In response to a May 3 letter regarding genetically modified organisms having no adverse effects: Biotech giant Syngenta has been criminally charged with denying knowledge that its genetically modified Bt corn kills livestock during a civil court case that ended in 2007.

Syngenta’s Bt 176 corn variety expresses an insecticidal Bt toxin (Cry1Ab) derived from the bacterium, Bacillus thuringiensis, and a gene conferring resistance to glufosinate herbicides.

European Union cultivation of Bt 176 was discontinued in 2007. Similar varieties however, including Bt 11 sweet corn, are currently cultivated for human and animal consumption in the EU.

In India, where livestock are left to graze on post-harvest cotton, thousands of livestock deaths have been recorded in different villages where Bt cotton is grown. Following mass deaths of sheep grazing on Bt cotton, post-mortem analysis carried out in the laboratory revealed abnormal liver, enlarged bile ducts and black patches in the intestine.

GMOs are bad science.
