Question
A: In addition to the response provided by Steve Savage, it may be helpful to know that technology developers conduct numerous years of studies on new GM plants in the field to assess whether the introduced GM trait impacts the “weediness” of the plant, relative to its non-GM counterparts. In other words, we conduct studies and collect data to answer these questions: Is this GM plant more likely to become a weed? If the trait transfers to a non-GM relative, would it make those plants more aggressive or weedy? As Steve Savage notes, the closely related relatives that can su [...]
A: Plants can only pollinate members of their own species or sometimes very closely related species. It is relatively easy to know whether there are any "outcrossing issues" with a new GM plant. This is one of the issues that the USDA considers whenever it approves of outdoor trials with new GM crops and when it makes the final "deregulation" decision. Of course, GM versions of a crop can cross pollinate non-GM versions of the same crop, but this is nothing new to agriculture. For a very long time, it has been necessary to isolate seed production fields of var [...]

Q: What is GMO corn and is all corn genetically modified?
A: ‘Is corn a GMO?’ is a very common question when discussing GMOs. In my response, I’ll cover some GMO corn facts and whether or not all corn is GMO. Firstly, how is corn genetically modified? Well, corn has been grown by humans for approximately 10,000 years and its genetics have been heavily modified through breeding and mutation to improve its utility as a crop over this very long period. The modern technique of transgenesis has been used to further improve the agronomic characteristics of corn over the last two decades. Transgenesis has become synonymous with the term “genetically modifie [...]
GMO Basics How GMOs Are MadeQuestion
Q: Why not breed desired qualities into plants as we have for 10s of thousands of years?
A: Agriculture is commonly considered to have begun about 10,000 years ago, and crops have been continuously improved ever since. New crop varieties have been developed to improve such properties as nutritional quality, yield and harvestability, as well as to remove mammalian toxins. By identifying favorable traits in individual crop plants or their wild relatives, breeders can cross such individuals with commercial lines to create new, improved lines. Mutations―arising, for example, through chemical treatment or radiation―are also used to introduce new genetic variation that breeders can u [...]
GMO Basics How GMOs Are MadeQuestion
A: If a researcher could identify a gene that prevents red rot, it would be possible and potentially a better solution than conventional breeding techniques in sugarcane. At the present time, some of the major companies are in early development on sugarcane for herbicide tolerance and higher yield. We haven't heard about any disease resistance yet. For a look at what's in the pipeline, please see the CropLife International website at www.croplife.org and search for "pipeline." [...]
GMO Basics How GMOs Are MadeQuestion
A: Currently, a voluntary system is available for retailers to designate GM and organic produce. This system is similar to the voluntary kosher label to assist consumers in making religious rather than health-related choices. Health related labels are mandatory and required by the U.S. FDA. SKU Produce Look-Ups or PLUs that start with the number 8 designate GM produce, and PLUs that start with the number 9 indicate that the produce is organic. For example, the PLU code for a standard yellow banana is 4011 while an organically grown standard yellow banana would be 94011.This system wa [...]
Health & Safety LabelingQuestion
Q: What cooking oils are NonGMO?
A: The most widely used cooking oils for home use are soybean, canola, corn, sunflower, olive, and peanut. Other specialty oils are sold but aren’t widely used (e.g. grapeseed oil). Of the major cooking oils, olive, sunflower, and peanut oil come from crops where no GMO technology is used. In addition, any organic versions of soy or canola oil would not make use of any GM technology. However, through processing, one cannot tell the difference between GM and non-GM soy and canola cooking oils. They are chemically the same. [...]

Q: Are genetically modified foods safe
A: If you were to look for a common theme among most of the questions and responses on GMO Answers, your question would be it! GMOs have been in our food supply for almost 20 years, and GM ingredients are found in 70 to 80 percent of the foods on your grocery store shelves. If GMOs were not safe, we would have a big problem. Fortunately, science shows us that there is no evidence of harm from GMOs. GM crops are repeatedly and extensively tested for consumer and environmental safety, and those tests are reviewed in the U.S. by the Department of Agriculture, Environmental Protection Agency [...]
