Labels for Genetically Modified Foods Are a Bad Idea
NCPA August 30, 2013
This past June, Connecticut and Maine became the first states to pass bills requiring labels on all foods made from genetically modified organisms (GMOs). In November 2012 California voters rejected the similar Proposition 37 by a narrow majority of 51.4 percent. "All we want is a simple label/For the food that's on our table," chanted marchers before the elections. The issue, however, is in no way simple, says Scientific American.
We have been tinkering with our food's DNA since the dawn of agriculture.
- By selectively breeding plants and animals with the most desirable traits, our predecessors transformed organisms' genomes, turning a scraggly grass into plump-kerneled corn, for example.
- For the past 20 years Americans have been eating plants in which scientists have used modern tools to insert a gene here or tweak a gene there, helping the crops tolerate drought and resist herbicides.
- Around 70 percent of processed foods in the United States contain genetically modified ingredients.
Instead of providing people with useful information, mandatory GMO labels would only intensify the misconception that so-called Frankenfoods endanger people's health. The American Association for the Advancement of Science, the World Health Organization and the exceptionally vigilant European Union agree that GMOs are just as safe as other foods. Compared with conventional breeding techniques (which swap giant chunks of DNA between one plant and another) genetic engineering is far more precise and, in most cases, is less likely to produce an unexpected result. The U.S. Food and Drug Administration has tested all the GMOs on the market to determine whether they are toxic or allergenic. They are not.
Many people argue for GMO labels in the name of increased consumer choice. On the contrary, such labels have limited people's options. In 1997, a time of growing opposition to GMOs in Europe, the EU began to require them. By 1999, to avoid labels that might drive customers away, most major European retailers had removed genetically modified ingredients from products bearing their brand. Major food producers such as Nestlé followed suit. Today it is virtually impossible to find GMOs in European supermarkets.
Americans who oppose genetically modified foods would celebrate a similar exclusion. Everyone else would pay a price. Because conventional crops often require more water and pesticides than GMOs do, the former are usually more expensive. Consequently, we would all have to pay a premium on non-GMO foods, and for a questionable return.
