Smart Talk: Are genetically modified crops safe?

Written by Scott LaMar, Smart Talk Host/Executive Producer | Feb 16, 2015 11:21 AM

What to look for on Smart Talk Tuesday, February 17, 2015:

In the twenty-first century the vast majority of corn, soybeans, and cotton grown in the United States is genetically modified to resist pests or pesticides. Genetically modified organisms, or GMOs, such as "Roundup-ready corn" have caused some of the most controversy among anti-GMO advocacy groups. They fear that the widespread use of the pesticide Roundup on herbicide-resistant crops like corn may cause health problems in adults and children.

Close to home, anti-GMO groups like GMO Free Lancaster County have voiced concerns about the use of genetically modified crops and their pesticides in the county famous for having the highest density of organic farms in the state of Pennsylvania.

Appearing on Tuesday's show are molecular biologist Dr. Nina Fedoroff from Penn State University to discuss how genetically modified crops are developed and what problems they are designed to solve. We'll also speak with the founder of GMO Free Lancaster, Zoe Swartz as well as Emily Givler, a pediatric nutrition consultant, who are advocating to stop the use of genetically modified crops and their pesticides in Lancaster County.

    My understanding is what they're doing is producing a plant that withstands being sprayed with a herbicide; Namely roundup.

    Plus, I don't believe that the plant will produce a seed that will germinate.

    So, taking those two effect into account, I don't think that they're a good idea.

    What we'll end up with is the possibility of cross pollination and weeds becoming resistant to the spray. And farmers that use traditional farming practices ending up with plants who's seeds do not germinate. This will result in one or two major corporations controlling the seed supply.
    Scott, I hope you cover that farmers are being sued for patent infraction, I believe because their crops are being cross pollinated. Which to me is a good indication of the squeeze from major corporations that will result if we keep using GMOs.

    • John H. img 2015-02-17 09:08

      If anyone states that it's about producing more crops, if we needed the addition grains the federal government wouldn't of had a program that pays farmers not to plant crops.

  • Robert D Colgan img 2015-02-17 09:09

    As I drive around here in southcentral PA during the Spring planting, I find it absolutely shocking to see that no-till farming with its generous application of glyphosates has created a moonscape in countless thousands of acres of farmland.

    The insects are disappearing.
    The birds are disappearing.
    The animals are disappearing.

    Yet the manufacturers of those herbicides--and pesticides--have insisted for years they are NOT a risk to the public.......even when it was revealed they have known for years they are endocrine disrupting carcinogens and that the companies had hidden the truth for years from the American public.

    This is a menace far greater than smoking-------which killed what?--millions? before it was finally acknowledged the tobacco companies had known about and hidden the true health risks from disclosure.

    Those glyphosates need to be banned-------IMMEDIATELY.

    I heard the intro for today's show. I will be teaching today, but I wanted to comment on the use of "autism."

    I believe in natural foods, etc. I was a hippie back in the day, was a founder of a natural foods co-op in West Va.

    I was afraid of vaccines and autism when my daughter was a baby. But we did have her vaccinated because we felt it was the responsible thing to do for the community: herd immunity.

    The only reason a person can get away with not vaccinating is because everyone else does.

    Now, so many parents have not vaccinated that we have outbreaks of measles, a disease that in 2000 was declared eradicated.

    I do not like the idea of GMOs, for sure, but I think we need to be more cautious throwing around "autism" unless you have the science to back it up, with peer reviewed studies published in reputable journals.

    Science has shown that vaccines do not cause autism. The study by the British doctor from about 10 years ago was debunked yet antivaxers keep using it to justify not vaccinating. That doctor can no longer practice.

    Now, we see the outcome of using faulty science to justify personal belief.

    I bet you already know all of this, but I thought I would throw it out there.

  • redoerfler img 2015-02-17 09:30

    I take exception to Dr Federoff's comment to Zoe Swartz. The argument that "so-and-so isn't a________" biologist, MD, etc. is specious. This means that citizens have no valid opinions after their own review of the science just because they don't have a certain credential? By that logic, none of us has a civic right to comment on anything outside our vocation! By the way I am myself a PhD in Nursing. I am aware of my limits regarding ag biology, but by no means am ill-equipped to comment on what affects my environment.

    • Dr Mark img 2015-02-17 09:36

      You may take exception, but this is because you misunderstood the point. The "so-and-so" was being cited as an expert, when in fact the particular so-and-so in question (Stephanie Saneff) has no particular expertise in toxicology, medicine, or environmental science. Dr Saneff publishes this work strictly in junk journals.

      So while you are certainly entitled to your opinion, it would not be proper to cite you as an expert on glyphosate biology.

      • redoerfler img 2015-02-17 09:58

        I disagree. You are taking the same position as Dr Federoff: lack of disciplinary expertise automatically refutes any point others make--yet we all have to live in this world. I did not misunderstand. This is not a discussion of "glyphosphate biology"; it is a discussion of politics. The main issue is disclosure--these tiny discussions of various aspects of GMO biology are simply the industry trying to protect against mandatory disclosure. If GMOs are such a good idea, then industry can disclose and let the public decide with their wallets.

        • Dr Mark img 2015-02-17 10:12

          You clearly did misunderstand, and continue to do so either intentionally or otherwise (especially in accusing me of claiming that lack of disciplinary expertise refutes "any" points, something I certainly have not said at all). The only time Dr. Federoff addressed anything involving authority was to point out that the mainstream scientific position on glyphosate biology was in opposition to the "expert" that Zoe Swartz cited. That was all.

          The discussion of the politics is, of course, a larger issue and all are entitled to their own opinion. However, we must insist that these opinions be based on facts-- and people are not entitled to their own versions of those. That is the point Dr. Federoff made, and you continue to miss.

  • Dr Mark img 2015-02-17 09:31

    Interesting that people are mentioning the correlation between GMO use over time and rising rates of autism. In fact, there is a much greater correlation between the use of organic foods and autism.

    Zoey Swartz seems to have no idea what a "species" is. Why would anyone listen to her pseudoscientific claptrap?

    Remember, everyone: correlation does not equal causation!

    Talking about gut biomes and pesticide use is nonsense on multiple levels. Pesticides are not antibiotics for one thing, and gut bacteria are not susceptible to them. Also, humans ingest very little of these pesticides on their food-- they break down in the environment and foods are washed before consumption. Moreover, pesticides would have to withstand the pH 1 of the stomach before having significant action on gut bacteria anyway. This is quite a stretch, and has never been proven to occur.

  • Mark img 2015-02-17 09:38

    I think there is not enough information about the safety of GMO crops on human and animal health to deem them totally safe. That said, any product genetically tweaked to increase yields in conjunction with a specific chemical manufactured by a company with the nasty reputation of Monsanto is something I will avoid like the plague. Monsanto has an unsustainable, aggressive and strictly profit-based business model that I definitely do not want to support. Since GMO corn and soybeans go to animal feed, I’ll stick with a mostly vegetarian diet and if purchasing soybeans for my consumption. I’ll make sure they are GMO-free...

    • Dr Mark img 2015-02-17 10:01

      Some GMO seeds can be grown on their own, some cannot. Some which cannot are designed to be infertile so that farmers have to purchase new seeds every time. This is a choice that is particular to a given genetically modified organism, not a feature of GMO in general.

  • Dr Mark img 2015-02-17 09:57

    One significant problem, as I see it as both a physician and a bioscientist (MD and PhD), is that "GMO" is not one thing. Genetic modification is a technique, and there are a wide range of genetic modifications that can be made to an organism.

    Some of these modifications increase the nutritional content of a food crop. Some allow foods to produce their own natural pesticides or to resist insects, vastly reducing the amount of chemical pesticides that are sprayed on fields. Only some are of the infamous 'BT' variety that allow increased resistance to glyphosate (which, incidentally, is a rather safe chemical).

    So what is it people are opposed to, exactly? I suspect it's mostly an undifferentiated fear of what they simply do not understand. Even as a supposed "expert", Zoe Swartz has made uncounted scientific errors in this segment. How are people who spend much less time on this issue supposed to make a clear judgement?

    • Barbara from Atglen img 2015-02-17 13:27

      Dr Mark, I believe you are mistaken when you state that Bt corn is made to withstand direct application of glyphosate/Round up. Bt crop species are developed using genetic materials from a different bacteria than are Round Up Ready glyphosate resistant crop species. Some species are engineered with both, and these will both create a systemic insecticide and resistance to glyphosate. But Bt and Round Up Ready are two different modifications.
      From the University of Kentucky College of Agriculture website:
      "Bacillus thuringiensis, and the gene of interest produces a protein that kills Lepidoptera larvae, in particular, European corn borer. This protein is called the Bt delta endotoxin. Growers use Bt corn as an alternative to spraying insecticides for control of European and southwestern corn borer."

    This discussion sounds eerily similar to the anti-vaccine discussions that were more prominent during the past decade. As was the case there, individuals were using pseudo-science to champion certain positions and mislead individuals about the supposed dangers of vaccines. The recent measles outbreak is evidence of what happens when these individuals are provided an equal forum as scientist.

    Scott Lamar's comment was irresponsible for potentially linking GMO plants to autism and food allergies. There are no scientific studies (peer reviewed and validated by other research) that show this link, only anecdotal or inferred based on exposure to a pesticide directly, not through food consumption.

    Thank goodness Dr. Federoff has been able to be reconnected to the discussion. She is the only sensible voice in this conversation.

    • Barbara from Atglen img 2015-02-17 17:26

      Round Up Ready corn, soy, etc. are created in order to be able to spray Round Up directly on the growing food plant. Because of this, the presence and consumption of glyphosate in our food has increased. This is of great concern to me. Some GMO advocates will make crazy remarks like, "You can drink a whole glass of Round Up and it won't hurt you," The next time I hear someone say this, I swear I'm going to ask him bring his youngest child or grandchild in, and invite him to have the child drink it right there! (Knowing fully well, that I would never let a child drink a glass of glyphosate. But you see my point.) and there is research that Round Up/glyphosate has a great deal of potential for harm. Here is a study that I have read about he potential link between glyphosate and breast cancer:

        Well, Dr. Fedoroff is being very polite, not surprising. But it's like debating evolution. You imply by bringing these people on that there is some kind of equivalence between Dr. Fedoroff's encyclopedic knowledge and their talking points. And they're allowed to conflate pesticides and herbicides... and to imply that natural foods are not composed of CHEMICALS (most of which you can't pronounce). >99% of the pesticides and carcinogens that we encounter in our foods are from natural sources (according to the inventor of the AMES carcinogen test, and many others) -- which is of course why evolution gave us livers, not just to metabolize drugs. Or that viruses have been transferring genes between species for a very long times. But no one has the time to educate your listeners on all of these issues, which are necessary to get past the talking points. Autism indeed -- we all know that's really caused by vaccines, right? Did you have a show on that in its heyday? As you can tell, I'm still really mad about this, and I'm not as polite as Dr. Fedoroff. And since correlation is apparently causation, you must have been cutting her off on purpose (QED).

  • Barbara from Atglen img 2015-02-17 10:18

    Dr Federoff commented twice that Dr Stephanie Seneff is not a biologist, and in this way she attempts to discredit the Samsel and Seneff study. We hear this all the time from GMO advocates, and I believe this is intended to mislead. Dr Seneff is a professor of Computer Science and Artificial Intelligence at MIT. She is a highly regarded mathematician and statistician. The Samsel and Seneff study is a research review. Any scientist, who knows very well what this means, who still criticizes not the merits of the study itself, but the credentials of the authors, is purposely trying to confuse the public. The truth is that Dr Seneff is eminently qualified to compile and statistically analyze the research she cites. She cites both landmark and recent research done by scientists of various disciplines published in peer-reviewed journals , and derives not only strong correlations, but also probable causations, for the potential of harmful outcomes from the use of glyphosate pesticide resistant GMO's.

    I enjoyed this all-too-short conversation about genetically modified organisms and how they impact our food supply. One reason supplied for the purpose of genetically modified organisms was to increase our food supply. The response to that was that we already have a very large food supply, most of which ends up in land-fills. What seems obvious to me is that not only are we mass producing foods that only look like real foods, but they are not as nutritionally sound. So we are literally starving ourselves by eating this toxic food, while others in the world are actually starving...
    don't tell me that this process is not politically or profit-driven.

    There is a lot of information about GMOs "in the news." Unfortunately, that information is often misleading or simply inaccurate and it leads to fear spreading throughout the public. Those fears often lead people to reach conclusions that are not based on facts or science. Those fears, however, are real, even if the reason for the fear is not. Moms, who do the majority of food buying for the family, are especially concerned, because they rightly do not want to feed their family anything that is harmful. Here are some thoughts to help alleviate those fears:
    *GMOs are Safe - There has never been a single documented case of human health or animal health issues related to GMO food in the 20 years they have been on the market. More than 600 scientific studies support the safety of GMO food.
    *GMOs are Endorsed - The United Nations Food and Agriculture Organization, the World Health Organization, the American Medical Society and hundreds of other health groups have concluded that GMO food does not pose any more risk to people than non-GMO food.
    *GMOs are Tested - GMO crops are extensively and continually tested for consumer and environmental safety. Test are conducted and reviewed by the Departments of Agriculture and Environmental Protection, along with the FDA and similar international organizations.
    *GMOs are the Same - There is no significant difference between crops using GMO seeds and those from non-GMO seeds. If the food was different, such as if it had different nutritional properties or included an allergen that consumers would not associate with that type of food, then USDA and FDA would require that information to appear on a label. FYI... that has never been the case in the history of GMO food.
    *GMOs are positive Environmentally - Farmers are able to use far fewer pesticides and fertilizers than they did before using GMO seeds. The crops are more drought resistant and allow farmers to grow more food on the same amount of land.

    • Barbara from Atglen img 2015-02-17 13:10

      It seems to me that there are also studies that will refute every point that you make. I read this last year, and I think you are either wrong, or that the so-called benefits of GMO's are based on a strong need to believe they are better than they really are.

      • GMO guru img 2015-02-20 13:58

        While this is undoubtedly true, science goes forward on "the weight of the evidence." So if one study says they're dangerous and one study says they're not, you don't know what to believe. If 1 study says they're dangerous and 10 studies say they're not, you'd tend to begin to believe they're not. By the time it's 1 dangerous to 100 not dangerous, it's a pretty good bet that you can ignore the one that says they're dangerous. In the case of GMOs, it's about 1 to 1000 at this point.

    What bothers me most is everyone using the argument that correlation does not equal causation - while this is true, it's also a beacon of hope that people hold onto. Did we not forget that correlation is how we were able to say that cigarettes cause cancer and a whole lot of other health concerns. The tobacco industry wants us to forget their deceptive advertising from the 1950s that depicted smoking as “Best for You” as approved by “50 years of scientific tobacco research”. The truth is the tobacco companies only cared about their own profits and not about the health of their customers. The same is true for the biotech industry - GMOs do not benefit the consumer only the biotech industry's pocket. And they will attack and discredit anyone that disagrees with this because they own our politicians and our government. Keep on saying that correlation does not equal causation meanwhile our kids are paying for it. This generation of children are the sickest in history. We need to start thinking differently before its too late.

    • DrJ img 2015-02-17 14:00

      But you're confusing even the nature of the correlations involved. The tobacco correlations were between people who smoked and people who didn't smoke. This "correlation" is "things that occurred over the last several decades". Come on. Maybe the astronauts brought health issues back from the moon!

    • Barbara from Atglen img 2015-02-17 14:01

      Sheena, you are absolutely correct. The phrase " Correlation is not causation" is thrown around so much by GMO advocates, in order to refute the validity of the statistics about the strong correlation between the increases in GMO food production and concurrent increases in reported cases of autism over time. I agree this correlation does not prove cause. But if I were a gambler, insurance underwriter, or a stockbroker, I would be paying very close attention to strong correlations. As a mother buying food for myself and my family, I would not bet the health and well-being on the possibility that the correlations are meaningless. Strong direct correlations indicate a need for more research!

    Americans have 10 times the glyphosate accumulation in their urine as recent testing shows than Europeans. Even worse, the chemical is present in unusually high quantities in the breast milk of American mothers. Dr. Stephanie Seneff refers to glyphosate as “a deceptively simple molecule” that kills by interrupting the shikimate pathway in weeds and other pest plants. Because our human cells don’t have this same pathway, scientists and researchers mistakenly assume glyphosate exposure is harmless to us. However, the flora residing in our intestines (where they help us digest food) do have a shikimate pathway, and so when glyphosate kills these beneficial bacteria, it harms our immune system. This science is explained in a paper, which Seneff wrote with co-author Anthony Samsel and appears in the online journal Entropy. For anyone interested:

    I can't site studies of harm and tragedy caused by GMOs, pesticides, and chemical fertilizers but I do know that I would not run barefoot through the streams I did as a child. I also gave up fishing in any bodies of water near human habitation. I don't have to be a scientist to know something is wrong with the way we grow food now. You can site all the studies in the world funded by agribusiness and try to tell me not to worry, we're scientists, and we are watching out for you. But I'm not buying it!

    It is so easy to sell fear:
    The farmer talked about how that they would spray Roundup to corn that is 3 feet tall. That is in the second or 3rd week of June. The corn is harvested 2 months after. Are you telling me that Roundup hangs around in the environment and the corn all that time? I do not know of any study that shows that it does. If he wishes to grow organic or Non-GMO corn there is a market for that.
    Good luck.

    Breast milk study is not verifiable. But is was touted as absolute fact.

    I am not certain that GMO corn is safe. but I am also not certain that getting up in the morning is safe either but I do it anyway. I give you the permission to live in fear of every assumed risk but please stop trying to sell it to me.

    Jacinta asked...
    I would like to know if we should be safe choosing organic diets. Would that steer us safe from all or most GMO foods if we find it scary or unconvincing to consume them.
