Is the Long-Term Safety of Genetically Engineered Food Settled? Not by a Long Shot.

Doug Gurian-Sherman, senior scientist, Food and Environment, Union of Concerned Scientists

One of the most contentious issues surrounding the controversy about genetically engineered (GE) foods is whether there may be long-term safety risks, and whether current regulations are sufficient to prevent such risks from occurring.

As I briefly discussed in my last post, major science organizations have said that some GE foods produced by current methods could be harmful, and have provided some examples of the kinds of harm that might occur.

The current situation

No long-term safety tests in animals are required by any regulatory agency. In some circumstances, 90-day, so-called sub-chronic tests may be required in Europe. But 90 days is far short of the one to two years that usually satisfy long-term safety test requirements.

Long-term experiments are required for products like drugs and chemical pesticides, and sometimes for food additives. They are considered important or necessary for determining harm that may take years to develop, such as cancers, Parkinson’s disease, and so on.

Recently, the American Association for the Advancement of Science (AAAS) Board of Directors cited a review of several long-term and multi-generational studies by Snell and colleagues in support of their claim that GE foods are safe and well tested.

The study cited by the AAAS Board has made the rounds in recent months, being used to claim that long-term studies show that GE is safe, and that shorter-term tests are sufficient.

The study authors extrapolate from the reviewed research that GE crops can be safely used in foods, based on currently required tests. For example, at the end of the paper’s abstract they write: “The studies reviewed present evidence to show that GM plants are nutritionally equivalent to their non-GM counterparts and can be safely used in food and feed.” They also conclude that 90-day tests are usually sufficient, and even these may not always be needed.

The study makes some useful contributions, but a careful reading shows that it contains some serious flaws. These limitations — some of which involve the interpretation of the results by the authors — eliminate the value of this study for drawing general conclusions about the safety of GE foods, or the adequacy of current shorter tests to reveal long-term risks from engineered foods.

Cincinnati Passes Resolution Requiring GE Food Labeling

Yesterday, the city of Cincinnati became the first in Ohio to pass a resolution to require the labeling of genetically engineered (GE) foods, citing that consumers should have the right to know what is in their food. The consumer advocacy organization Food & Water Watch brought the resolution to city council as a part of their "Let Me Decide" campaign to make GE labeling the law. GE foods have not been fully tested for their impacts on human health and the environment.

Alison Auciello, Ohio-based organizer for Food & Water Watch said, "genetically engineered foods are potentially unsafe, and consumers should have the right to decide for themselves if they want to eat GE foods. It took regulation to get food processors to label ingredients and nutrition facts on labels, and now we're calling for federal lawmakers to require the labeling of GE food."

The majority of processed foods are genetically engineered, but unlike fat, sodium and sugar content, labels do not disclose which foods contain genetically engineered (GE) ingredients. Biotechnology companies submit their own safety-testing data, and independent research is limited on GE foods because licensing agreements that control the use of patented seeds prohibit cultivation for research purposes.

Genetically engineered foods are made by inserting the genetic material from one organism into another to achieve a desired characteristic such as resistance to herbicides or pesticides. Roundup Ready varieties of corn, for example, are engineered to withstand treatment with the Roundup herbicide. But, the unintended consequence of increased use of herbicides has been a rise in "superweeds," aggressive weed species like ragweed and pigweed that have become immune to Roundup.

Cincinnati Council Member and resolution co-sponsor Wendell Young said, "this is about transparency, about ensuring that people can make informed choices about what they feed themselves and their families. Consumers have a right to know what is in their food, especially until we know for certain whether genetically engineered foods are truly safe."
