“There is no credible evidence that GMO foods are safe to eat.”

David Schubert, Salk Institute of Biological Studies

“[The] research [on GMOs] is scant…. Whether they’re killing us slowly— contributing to long-term, chronic maladies—remains anyone’s guess.”

Tom PhilpottMother Jones

“Genetically modified (GM) foods should be a concern for those who suffer from food allergies because they are not tested….”

Organic Consumers Association

A popular weapon used by those critical of agricultural biotechnology is to claim that there has been little to no evaluation of the safety of GM crops and there is no scientific consensus on this issue.

Those claims are simply not true. Every major international science body in the world has reviewed multiple independent studies—in some cases numbering in the hundreds—in coming to the consensus conclusion that GMO crops are as safe or safer than conventional or organic foods, but the magnitude of the research has never been catalogued.

Still the claim that GMOs are “understudied”—the meme represented in the quotes highlighted at the beginning of this article—have become a staple of anti-GMO critics, especially activist journalists. In response to what they believed was an information gap, a team of Italian scientists catalogued and summarized 1783 studies about the safety and environmental impacts of GMO foods—a staggering number.

The researchers couldn’t find a single credible example demonstrating that GM foods pose any harm to humans or animals. “The scientific research conducted so far has not detected any significant hazards directly connected with the use of genetically engineered crops,” the scientists concluded.
