Is hybrid corn 'genetically modified'? Is there a list?
Comments (14)Steve I've seen some people wondering if the BT crops are what are decimating bee populations. Here's one discussion. Walter Haefeker, the German beekeeping official, speculates that "besides a number of other factors," the fact that genetically modified, insect-resistant plants are now used in 40 percent of cornfields in the United States could be playing a role. The figure is much lower in Germany - only 0.06 percent - and most of that occurs in the eastern states of Mecklenburg-Western Pomerania and Brandenburg. Haefeker recently sent a researcher at the CCD Working Group some data from a bee study that he has long felt shows a possible connection between genetic engineering and diseases in bees. The study in question is a small research project conducted at the University of Jena from 2001 to 2004. The researchers examined the effects of pollen from a genetically modified maize variant called "Bt corn" on bees. A gene from a soil bacterium had been inserted into the corn that enabled the plant to produce an agent that is toxic to insect pests. The study concluded that there was no evidence of a "toxic effect of Bt corn on healthy honeybee populations." But when, by sheer chance, the bees used in the experiments were infested with a parasite, something eerie happened. According to the Jena study, a "significantly stronger decline in the number of bees" occurred among the insects that had been fed a highly concentrated Bt poison feed. According to Hans-Hinrich Kaatz, a professor at the University of Halle in eastern Germany and the director of the study, the bacterial toxin in the genetically modified corn may have "altered the surface of the bee's intestines, sufficiently weakening the bees to allow the parasites to gain entry - or perhaps it was the other way around. We don't know." Of course, the concentration of the toxin was ten times higher in the experiments than in normal Bt corn pollen. In addition, the bee feed was administered over a relatively lengthy six-week period. Kaatz would have preferred to continue studying the phenomenon but lacked the necessary funding. "Those who have the money are not interested in this sort of research," says the professor, "and those who are interested don't have the money."

Comments (48)Henry, I'm not questioning your credentials or your family's credentials. I'm questioning your circle-running of Google search articles for things you want to prove...and how you use some of them. While you seem to have a mind for science, your application of certain paper's topics to what you're trying to prove can be lacking. The "discussion" about the economics of large acreage farming and farmer choice burnt me out. I'm not getting into any more of that stuff...it's a never-ending circle. I understand nature is complex... I spend my personal and professional life studying it. I know large scale cropping systems, specialized hybridizing (CMS/etc), plant breeding, genetics, and the economics of cropping system especially...I also know soil science (another degree I hold), but I don't get to apply it that much in my profession. Just because I know about "science" things...it doesn't make me an expert or knowledgeable about nuclear reactions in power plants or making new elements from atomic super collider reactions. The field of science is just too broad in scope. Hell, even close fields aren't the best of neighbors. Ecologists and Horticulturalists share some similar/same terms, but the final definition is going to be different depending on which one you ask. I'm not out there trying to have a discussion/argument on the best way to raise hostas...because other than micropropagating them, I know jack about them. Expects have to specialize at some point. I know what I'm an expert at and where I'm lacking. You gotta draw that line, especially when you're diving into material you don't fully grasp. I chose a profession which puts me on the ground floor of the industry, and on the cutting edge of the technology (both GMO and non-GMO). This industry goes on without me...it happens independent of me...farmers don't care if I exist. What's going on out there doesn't care what I think. What's going on out there is what I'm exposed to on a daily/weekly basis, though. No one's wishes can make the reality of the decisions made on the ground different. It's happening whether people want to believe it or not. I've been in fields in almost 20 states, I've seen/gathered/crunched-numbers of pest data, I've used the pesticides/herbicides, I've grown the plants in greenhouse and field environments, I've talked so many farmers in so many different climates... Sorry, I can't give you their phone number and I'm not going to play Google search tag (because it never ends). If you choose to dismiss the things I say, fine. Wishes and hopes don't change what's going down on the ground floor of this particular field (or many fields).

Comments (11)The consumer must educate themselves. Obviously there exists widely varying opinions and deep emotions on the subject of GM foods as well as sources of information on the subject. Let there be a broad, bright source of light whose source is rooted in science rather than emotion and opinion shining out across the world. What precious little research on GMOs in food I've seen in refereed journals doesn't make a good case for consuming GMOs but I haven't seen nearly enough to conclude that they are a threat to my diet. Much more work needs to be done for me to make a rational, knowledge based decision. In the meantime, this country needs to get it's feces congregated and institute COOL, Country of Origin Labeling at the very least, if we can't get that done there is no hope for trying to get GM labeling. The thought of eating produce from China is both sickening and a tad frightening considering their environmental laws and regs.....See MoreAbout Genetically Engineered foods
Comments (32)Oh come on Marcia that just isn't fair. I was never implying that anyone was stupid and I worded that very carefully so no one would think that I did. If anyone else feels that I was calling them stupid I am sorry and that was not my intention. I do however feel that the subject of genetic engineering is getting an unjustified bad reputation. Since you have brought up education I will reveal mine. I have a BS in bioinformatics and computational biology with minors in computer science, statistics and chemistry. I am currently working on my MS in biotechnology. There is more than a few people eating GM crops currently and they aren't dying. Many people mention that the long term effects of GM produce should be studied and I agree with that and if they find a reason to remove the products they will. But at this current time I see no reason to have a concern. Tests are performed on the plants to look for toxic substances and allergens what more do you need. If anyone doesn't want to eat GM crops I am sure they can greatly reduce their intake of them by shopping at local farm stands. I have read a lot of the remarks against genetic engineering and they are all full of unsubstantiated claims and misleading experiments. Marcia, since you have studied biology I am sure you are familiar with the ames test. The ames test wasn't around in the time of cyclamate, our technology has come a very long way since then. Before the ames test scientists had to feed mice a lot of the compound and then dissect the mice and examine every inch of tissue for cancer. Now with the ames test all you need to do put the compound on a special agar plate and incubate for less than 2 days. And there are other countless advances to ensure safety. Even if the genes were able to somehow get into every organism within a species knocking out genes is not even as hard as putting them in. If you are interested here is one article about RNA interference . Also if you have taken genetics you know that you would never see the gene taking over a population it would reach Hardy-Weinberg equilibrium within the population. Also here is the FDA position on labeling genetically engineered food: Labeling Issues FDA has received many inquiries asking about the labeling of genetically engineered foods. Congress has provided FDA a limited basis on which to require labeling. Generally, for FDA to require labeling there must be something tangibly different about the food. In general, this means most genetically engineered foods will not need special labeling because they will be similar to traditionally bred varieties. But there are exceptions, such as when a gene from a food that could cause an allergic reaction--peanuts, for example--is transferred into another food. In that case, FDA policy places the burden on the developer. "The food will have to be labeled so everyone will know it contains an allergen, unless the developer can show scientifically that the allergenicity has not been transferred," says Laura Tarantino, Ph.D., deputy director of FDA's Office of Premarket Approval. Fortunately, the products in front of us right now don't raise those issues." FDA also will require labeling if a company uses genetic engineering techniques to change a food's composition significantly. For example, when one manufacturer modified canola to produce increased levels of lauric and myristic acids in the seed oil, FDA agreed that the common or usual name for this oil would be "laurate canola oil" in order to distinguish it from traditional canola oil....See More- 12 years agolast modified: 11 years ago
