Have you ever wondered how GMO corn is made?
Roundup Ready Corn is genetically-engineered corn that has had its DNA modified to withstand the herbicide glyphosate (the active ingredient in Monsanto’s herbicide Roundup). It is also known as “glyphosate tolerant corn.” RR corn was first deregulated in the U.S. in 1997 and first commercialized in the U.S. in 1998. One variety of RR Corn, NK603, was linked to tumors in rats in the Seralini study last year. Read the full details in the study here:

Ten Things You Need to Know about the Seralini Study
1. Most criticisms of Séralini’s study wrongly assume it was a badly designed cancer study. It wasn’t. It was a chronic toxicity study – and a well-designed and well-conducted one.
2. Séralini’s study is the only long-term study on the commercialized GM maize NK603 and the pesticide (Roundup) it is designed to be grown with. See here: Why is this study important?
3. Séralini used the same strain of rat (Sprague-Dawley, SD) that Monsanto used in its 90-day studies on GM foods and its long-term studies on glyphosate, the chemical ingredient of Roundup, conducted for regulatory approval.
4. The SD rat is about as prone to tumours as humans are. As with humans, the SD rat’s tendency to cancer increases with age.
5.Compared with industry tests on GM foods, Séralini’s study analyzed the same number of rats but over a longer period (two years instead of 90 days), measured more effects more often, and was uniquely able to distinguish the effects of the GM food from the pesticide it is grown with.
6. If we argue that Séralini’s study does not prove that the GM food tested is dangerous, then we must also accept that industry studies on GM foods cannot prove they are safe.
7. Séralini’s study showed that 90-day tests commonly done on GM foods are not long enough to see long-term effects like cancer, organ damage, and premature death. The first tumours only appeared 4-7 months into the study.
8. Séralini’s study showed that industry and regulators are wrong to dismiss toxic effects seen in 90-day studies on GM foods as “not biologically meaningful”. Signs of toxicity found in Monsanto’s 90-day studies were found to develop into organ damage, cancer, and premature death in Séralini’s two-year study.
9. Long-term tests on GM foods are not required by regulators anywhere in the world.
10. GM foods have been found to have toxic effects on laboratory and farm animals in a number of studies.
In fact, Seralini validated by new EFSA guidelines on long-term GMO experiments–The European Food Safety Authority (EFSA) has issued guidelines for two-year whole food feeding studies to assess the risk of long-term toxicity from GM foods. http://www.efsa.europa.eu/en/efsajournal/pub/3347.htm
