Genetically Modified Foods
Experts View Regimen of Safety Tests as Adequate, but FDA's Evaluation Process Could Be Enhanced Gao ID: GAO-02-566 May 23, 2002Genetically modified foods pose the same risks to human health as do other foods. These risks include allergens, toxins, and compounds known as antinutrients which inhibit the absorption of nutrients. Before marketing a genetically modified food, company scientists seek to determine whether these foods pose any heightened risks. The Food and Drug Administration (FDA) published guidelines in 1992 to ensure that companies worked with the agency to assess the safety of genetically modified foods. GAO found that FDA's evaluation process could be enhanced by randomly verifying the test data provided and by increasing the transparency of the evaluation process, including communicating more clearly the scientific rationale for FDA's final decision on an assessment of genetically modified food. Scientists expect that genetic modifications will increasingly enhance the nutritional value of genetically modified foods. Although current tests have been adequate for evaluating the few genetically modified foods that have, so far, undergone relatively simple compositional changes, new technologies are being developed to evaluate the increasingly complex compositional changes expected. Monitoring the long-term health risks of genetically modified foods is generally neither necessary nor feasible. No scientific evidence exists, nor is there even a hypothesis, suggesting that long-term harm, such as higher cancer rates, results from these foods. Moreover, technical challenges make long-term monitoring infeasible.
