Despite being in use for almost 20 years with no health or safety issues, controversy continues to surround genetically modified crops and their regulation.
Bruce Chassy, a professor emeritus of food science and human nutrition at the University of Illinois at Urbana-Champaign, believes that after thousands of research studies and worldwide planting, "genetically modified foods pose no special risks to consumers or the environment" and are over-regulated.
Farmers have witnessed the advantages of GM crops firsthand through increases in their yields and profit, and decreases in their labor, energy consumption, pesticide use and greenhouse gas emissions, Chassy said. The overregulation of GM crops actually hurts the environment, reduces global health and burdens the consumer.
Despite the benefits, various regulatory agencies require newly developed GM crops to be put to the test with rigorous safety evaluations that include molecular characterization, toxicological evaluation, allergenicity assessments, compositional analysis and feeding studies. This extensive testing takes five to 10 years and costs tens of millions of dollars, and Chassy argues that this process "wastes resources and diverts attention from real food safety issues."
"With more than half of the world's population now living in countries that have adopted GM crops, it might be appropriate to reduce the regulatory scrutiny of GM crops to a level that is commensurate with science-based risk assessment," Chassy said.
Chassy chronicled the scientific tests used in pre-market safety assessments of GM foods and elaborate on the evidence from thousands of research studies and expansive GM plantings that he says show these crops do not present risks to consumers or the environment. The over-regulation of GM foods is a response not to scientific evidence, Chassy said, but to a global campaign that disseminates misinformation and fear about these food sources.
Chassy's talk, "Regulating the Safety of Foods and Feeds Derived From Genetically Modified Crops" was given at the AAAS meeting in Boston February 17th.
