In the United Kingdom, researchers from King’s College in London published their findings that there are higher levels of certain toxic chemicals in the GMO corn compared to non-GMO corn and that they are not substantially equivalent as regulatory bodies and industry often say they are. In particular, researchers found higher levels of putrescine and cadaverine in GMO corn, which potentially increase allergic reactions and have been linked to cancer causing nitrates in meat products.
The study compared non-GMO corn to the Roundup-resistant GMO corn variety called NK603. Researchers concluded that given the higher levels of toxins in the GMO corn, further research and a safety evaluation should be conducted on the GMO corn, especially for people who consume it long-term.
