GMO Answers was created to do a better job of answering your questions—no matter what they are—about GMOs. We believe it is important to seek out and listen to the questions consumers are asking so that we can provide answers and links to resources that help address consumers’ concerns about GMOs, the technology behind them and their role in agriculture.
That’s why GMO Answers conducted a national survey to identify, for the first time, the top questions consumers have about GMOs. We’ve compiled the top 10 questions and reached out to scientists, farmers, doctors and other experts to provide answers. Over the course of the next nine weeks, we’ll post one new response each week, so we hope you’ll check back for new answers and follow us on Twitter at @GMOAnswers, where we’ll tweet new answers as they are posted! You can also find these answers on our Top 10 GMO Questions Pinboard.
If your questions about GMOs do not appear on the page below, please feel free to search our archives or submit a new question. We’re excited to provide answers to the top consumer questions and hope these resources will help you gather facts about GMOs so that you can better understand the role of biotechnology in agriculture.
In the United States, livestock have been consuming feed made from GM crops for almost twenty years. More than two-thirds of GM corn and half of GM soybeans are used for livestock feed. In that time, GMOs have never been detected in the milk, meat or eggs derived from animals fed GM feed.
First, it’s important to understand that almost all the food that we (or animals) eat contains DNA and proteins. The DNA and proteins found in food, GMO and non-GM, are released from the food and processed by the digestive system in our gastrointestinal tract. During digestion, GMO and non-GMO DNA is broken down into the four nucleotides that make up all DNA, and/or into small nucleotide fragments. Similarly, proteins, again GMO and non-GM, are broken down into one or a few of the 21 amino acids that exist in nature. Many, many studies have been conducted on the potential for GMO DNA or proteins to be transferred into animal tissues. No intact or immunologically reactive protein or DNA has been detected in animal tissue.
Therefore, as Alison Van Eenennaam, extension specialist in animal genomics and biotechnology at the University of California, Davis, explains, “Genetically engineered crops are digested by animals in the same way as conventional crops. Evidence to date strongly suggests that feeding livestock with genetically engineered crops is equivalent to feeding unmodified feed sources in terms of nutrient composition, digestibility and feeding value.” Additionally, Dr. Van Eenennaam states, “Genetically engineered DNA, or the novel proteins encoded in therein, have never been detected in the milk, meat or eggs derived from animals fed genetically engineered feedstuffs. Several studies have documented that small fragments of plant-derived, but not genetically engineered, DNA can pass into the tissues of animals that consume the plants.”
Are feeds made from GMOs safe for livestock?
GM crops, such as corn, soy and alfalfa, are commonly used for livestock, and more than 100 digestion and feeding studies have been conducted with food-producing animals, like beef cattle, swine, sheep, lactating dairy cows and chickens.
In a post for Facts About Beef, Ruth McDonald, professor and chair of food science and human nutrition at Iowa State University points out that “GM products have been in the U.S. food supply since 1996—hence we have years of practice that have shown no negative impact on animal or human health. Farm animals, the most carefully monitored animals on the planet, have been raised on GM corn and soybeans over several generations and there is no evidence of negative effects on growth, reproduction or disease. And there has been no documented case of human illness or allergen associated with GM foods.”

Last week, we addressed the claim that GMOs are contributing to the death of bees; this week we’ll discuss the second half of the question about butterflies.
There are a variety of factors impacting monarch butterfly populations, such as deforestation, parasitism, and ebbing populations of their host milkweed plants.
There are claims that GMOs and herbicides (more specifically an herbicide called glyphosate) are contributing to the decline in milkweed – a primary food source for monarch larvae (caterpillars)— and that the butterflies have been harmed by eating pollen from GM Bt corn. GMO Answers experts address both of these claims.
Andrew Kniss, associate professor of weed ecology and management at the University of Wyoming, explains why the cause for the milkweed decline is a complex issue, concluding that while herbicides may have played a role in the decline of species like milkweed, “the research does suggest that there are more important factors than herbicides responsible for the decline of native plant species near crop fields, including milkweeds.” This study he points to was conducted by USDA-ARS and Penn State scientists.
What can be done? Shifting land management practices is one important factor affecting milkweed and other nectar plants that sustain monarchs. Researchers, conservation groups, government agencies and the agricultural community are identifying ways to reestablish functional habitat on the agricultural landscape while continuing to recognize the need for productive agricultural systems. Farmers have an important role to play in the conservation of monarch butterflies and can support a monarch recovery by helping to replenish milkweeds in rural areas. Similarly, everyone can support a monarch recovery by helping to establish butterfly gardens in urban and suburban areas. There are hundreds of these gardens that have been planted through efforts by groups such as Monarch Watch and the Monarch Joint Venture.
With regard to pollen, we reached out to Dominic Reisig, an extension specialist and assistant professor of entomology at North Carolina State University, to further discuss the declining butterfly population. In this post he explains that “the butterflies need to eat the Bt in order to die. Only pest species, not non-pest species [such as monarch butterflies], eat GMO plants. Therefore, the non-target pest species are not exposed to the Bt and do not die.” He concludes, “GMOs are not contributing to the death of non-pest species of butterflies.”
The U.S. Department of Agriculture, has a website dedicated to its own research investigation into the claim that monarch butterflies might be harmed by eating pollen from Bt corn and found that “there is no significant risk to monarch butterflies from environmental exposure to Bt corn.” Additionally, a collaborative research effort by scientists in several states and Canada produced this report which found “no acute toxic effects at any pollen density that would be encountered in the field.”
It is important to note that before a genetically modified crop can be grown commercially, companies developing GM plants must demonstrate that the new plants are not harmful to “non-target” insects, such as bees and butterflies. This is part of the rigorous health and safety testing that GMOs must undergo before coming to market, which includes a mandatory review by the Environmental Protection Agency of GM plants that are insect resistant or herbicide tolerant to assess their environmental impact. This post by Steve Savage, discuss the extensive regulatory review process required for GMOs.

This is a big topic, so we are breaking the answer into two parts. This week we’ll address to the first half of the question regarding bees, next week we’ll explore butterflies.
The sudden and widespread disappearances of adult honey bees from hives, termed Colony Collapse Disorder (CCD), became a national concern almost 10 years ago. Claims have been circulated that insect protected GM crops harm bees, but these assertions have been refuted by the mainstream scientific community.
GMOs are not believed to have much of any impact on honey bee populations.
EPA et al recognize the bee populations may be challenged by a number of factors including pests and parasites, microbial disease, inadequate diet and loss of genetic diversity, as explained by Paul Driessen, a senior policy analyst and author, in this post.
Paul explains that “the proceedings of the U.S. National Academy of Sciences indicated that bees may be dying not from a single toxin or disease, but rather from a variety of factors.” He goes on to say “GM crops have not been implicated in CCD and, in fact, have made it possible to grow more food and other crops on less land, with fewer insecticides and even under conditions of limited rainfall or drought.”
If a variety of factors are impacting bee health, could GMOs be one of them? Bee Ambassador for Bayer Chris Sansone, who has more than 30 years of experience as a professor and extension specialist at Texas A&M University, points to several scientific studies indicating this is not the case. He notes that “genetically modified plants and their impact on honey bees have been widely studied, and the results indicate that GM plants are not harmful to bees.”
The insecticidal proteins produced by the currently available insect protected crops are derived from a common soil bacterium and all of the proteins used in insect-protected GM plants are tested for toxicity to honey bees. None of these proteins have provided any evidence of harm in either short or long term testing with both adult and larval honey bees.
Additionally, in May 2013 the USDA and EPA released a comprehensive scientific study on the many factors that contribute to CCD – none of which are GMOs.

Cathy Enright, executive director for the Council for Biotechnology Information, describes the labeling we do support in this response, she states, “when it comes to safeguarding your health and nutrition, we support the mandatory labeling of food, including GMO food, if it raises a safety or health concern, for example, to alert sensitive populations to the potential presence of an allergen. We also support mandatory labeling of GMO food if there is a change to the food’s composition, nutritional profile, taste or smell, or any other characteristic that would make it different from its conventional counterpart.”
In the United States, foods are labeled according to FDA policy, which requires a label “anytime a food differs from its conventional counterpart in a meaningful way, such as a reduction in nutrients, the introduction of an allergen or even a change in taste or smell.” The purpose of mandatory food labeling is to convey information to consumers about the safety and nutrition of a product.
It is critical that labels be factual, verifiable, understandable and not misleading. As Enright states, “We support mandatory labeling of food, including GMO food, when a food raises a safety or health issue—for example, to alert sensitive populations to the potential presence of an allergen.”
Enright further explains, “but we cannot support the mandatory labeling of GMO food just because the food in the market was produced using genetic engineering, for example, in wine, yogurt or bread made with GM yeast, vegetable oil made from GM soybeans, or cereal sweetened with GM sugar. These foods are as safe and nutritious as their non-GMO counterparts as determined by recognized authorities around the world.”
In this post, Greg Conko, senior fellow at the Competitive Enterprise Institute, discusses the “the unique ‘power and precision’ of genetic engineering” and the “intense scrutiny to which GM plants are subject by three different regulatory agencies in the U.S. alone.” He goes on to say, “Dozens of the world’s most prestigious scientific bodies, including the National Academies of Science, the American Medical Association and the World Health Organization, have studied genetic engineering for more than 30 years and concluded that such foods are at least as safe as, and often safer than, conventionally bred ones.”

- Genetically Modified Foods Are as Safe as Conventional Ones
Article provided by Greg Conko: http://gmoanswers.com/studies/genetically-modified-foods-are-safe-conventional-ones
Many consumers ask whether farmers who grow GMO crops are increasing their use of pesticides. Overall, pesticide applications have decreased, largely due to the adoption of insect-resistant crops, particularly in cotton (Agricultural economist Graham Brookes discusses in this post.)
Reducing pesticide applications saves farmers time and money by decreasing the amount of chemicals they need to purchase and the number of times they need to apply them to fields over the course of a growing season. This also has translated into documented benefits to the environment including the reduction in greenhouse gas emissions, equivalent to taking 10.2 million cars off the road for one year (GM Crops: Global Socio-Economic and Environmental Impacts 1996-2011, Graham Brookes & Peter Barfoot).
Graham also describes the benefit of herbicide-tolerant GM technology, stating that the “volume of herbicide used in GM corn crops decreased by 193 million kg” from 1996 to 2011. That’s more than a 10 percent reduction.” The use of one herbicide, glyphosate has increased however, as farmers sought to adopt herbicide-tolerant crops and to use more benign chemicals on their farms. Although the use of one herbicide has increased, this has not led to an increase overall. This has also raised questions about weed resistance to glyphosate, which John Soteres addresses in this answer.
Let’s first explore why farmers use pesticides to better understand the role GMOs can play…
Why are pesticides used?
Farmers use pesticides to stop unwanted predatory insects and invasive weeds from destroying their crops. Just as gardeners deal with caterpillars that can wreak havoc on their fruits and vegetables, farmers manage for a variety of pests that interfere with crop production, reducing yield and increasing costs to the farmer and consumer. (Did you know that the same Bt pesticide you may use in your home garden is what helps insect-resistant GM crops fight pests?)
How do GMOs play a role in reducing pesticides?
Several GM crops have been developed specifically for insect resistance or herbicide tolerance, which allows farmers to use fewer pesticides on GM crops. For example, the European corn borer is one of corn’s primary pests. It can damage the ears and stalks of corn by chewing tunnels, damaging the plant and inhibiting growth. Farmers can control for this pest by planting GM corn resistant to the European corn borer, which reduces the need for pesticides and helps increase yield by preventing damage to the corn crop.
Agricultural economist Graham Brookes discusses insect resistance in GM crops in this post, stating that it “provides a form of protection against pests and often replaces insecticides as a form of control.” Brookes goes on to say that “the use of GM insect-resistant technology has resulted in major reductions in the use of insecticides that have been traditionally used to control the pests the GM technology now controls.”
Furthermore, Andrew Kniss, a weed ecology and management professor at the University of Wyoming, explains how herbicide-resistant crops allow farmers to use fewer toxic herbicides in the field in this post.
This presentation from the Federal Department of Economic Affairs, Education and Research (EAER) in Switzerlanddetails the role of insect-resistant GM technology in the context of IPM. This article discusses how GM crops can help make agricultural production more efficient while reducing the environmental impact of pesticides.

This might surprise you, but long-term health studies have been conducted on GMOs. Aside from the fact that GM foods have a long, safe track record (17 years in the marketplace), 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 and Food and Drug Administration, and similar organizations internationally. Tests are conducted by both industry experts and independent organizations. This link lists 1,785 GMO safety studies, including long-term studies, many of which you can download, and this link will take you to a list of 610 more.
Furthermore, the European Union, which strictly regulates GM crops, has also conducted numerous studies on the safety of GMOs. You can find the results of those studies here. According to the European Commission, “the main conclusion, after more than 130 research projects covering a period of more than 25 years of research and involving more than 500 independent research groups, is that biotechnology, in particular GMOs, are not per se more risky than, e.g., conventional plant breeding technologies.”
In fact, every major scientific body and regulatory agency in the world has reviewed the research about GMOs and openly declared crop biotechnology and the foods currently available for sale to be safe.
Denneal Jamison McClung, associate director, UC Davis Biotechnology Program, also provides a full response on this topic here, where she explains that “from their introduction in 1996 until now, scientists have found, through repeated and extensive testing, that GMO foods are no more risky than comparable non-GMO foods, nor do they differ in nutritional value.”

The proper management of organic, conventional and GM seeds is an important issue.
The coexistence of multiple production methods – organic, conventional and GM – is not a new concept. Farmers have been producing different types of crops next to one another before and since GM seeds were first introduced in 1996, and they work hard every day managing their farms to ensure each crop meets the appropriate marketing requirements.
Don Cameron, a farmer outside of Fresno, CA, grows conventional and GM seeds on the same farm. We asked Don to answer this question, and he explains what he does at the farm-level to avoid pollination from surrounding crops, and how different crop management systems play a role.
You can review Don’s full response here.
Clean seeds are a concern for organic farmers before planting, as well as pollen drift from neighboring fields during cultivation. As Don explains, “Organic does not equal zero presence of a GM trait. Low-level presence of a GM trait in organic production is allowed as long as the grower has followed the organic process necessary for organic production.”
Mary Mertz also farms with a combination of seed types—conventional and GM—and happens to do so next door to an organic farm. Mary states, “Organic and conventional farmers are all in the food production business together. We need to work together and respect each other’s farming practices. This entails communication, heightened awareness of weather conditions and being solution-oriented to prevent problems from occurring in the first place.”
You can read her full response here.
Additionally, a report from the American Seed Trade Association explains that, "Building upon many generations of experience, coexistence involves agricultural best practices that bring the greatest benefit to all along the agricultural value chain from seed developers to farmers and from retailers to consumers — from field to fork." The report reminds us that, "The coexistence of various production methods is not a new concept to the agricultural community," and that, "Farmers are accustomed to producing different crops next to one another." Read the full report for more information on the set of tools used to facilitate coexistence in the seed industry.
NPR also explores the comingling of organic and GM seeds in this story and explains that, “Organic producers typically do try to minimize the presence of GMOs, because their customers don't want them. It's usually not too hard to keep contamination to a very low level.”

While the cost of food is impacted by various factors (the price of oil affects transportation costs; temperature changes can cause drought; etc.), GMOs play an important role in keeping those prices as low as possible. It’s estimated that corn-based products would be priced 6 percent higher and soybean-based products would be 10 percent higher if GM crops were not grown, according to a 2010 study by Graham Brookes et al.
But what role, exactly, does biotech play in the cost of food?
We reached out to Graham, who is an agricultural economist at PG Economics Ltd., U.K., to explain more about the complicated topic of food cost and explore the role GMOs play in the global food economy.
Key points from Graham’s response include:
- "The [GM] technology adopted to date has largely been productivity-enhancing and cost-reducing technology. This means additional global production has arisen from use of the technology, equal to an extra 122 million tonnes of soybeans, 237 million tonnes of corn, 18 million tonnes of cotton lint and 6.6 million tonnes of canola in the period 1996–2012.”
- “[T]he real price of food and feed products has fallen consistently during the last 50 years. This has come about not ‘out of the blue’ but from enormous improvements in productivity by producers. These productivity improvements have arisen from the adoption of new technologies and techniques.”

Lisa Katic, RD, shared her perspective on this question and explains that “No commercially available crops contain allergens that have been created by genetically engineering a seed/plant. And the rigorous testing process ensures that will never happen.”
In another post, Lisa goes on to say, “food allergies are mainly caused by eight major foods (milk, eggs, peanuts, tree nuts, soy, wheat, fish and shellfish) and account for about 90 percent of reported food allergies in the United States. First, it is important to note that only one of these eight major allergens listed above is a potential product of biotechnology, and that is soy. Of the remaining seven allergens listed, none is commercially available in genetically modified varieties.”
It is important to remember that if a person is allergic to a non-GM plant, he or she will also be allergic to the plant’s GMO counterpart. But GMOs do not introduce any new allergens. In fact, researchers, academics and companies are working on new GMOs that have the potential to help people in this area—for example, peanuts with very low allergen levels that have the potential to eliminate life-threatening allergies to peanuts. More information is available here and here.
Additionally, the U.S. Food and Drug Administration explains, “Evaluating the safety of food from a genetically engineered plant is a comprehensive process that includes several steps. Generally, the developer identifies the distinguishing attributes of new genetic traits and assesses whether any new material that a person consumed in food made from the genetically engineered plants could be toxic or allergenic.”

This is an extremely important question. Numerous questions similar to this and related topics have been submitted to GMO Answers, including questions about reports claiming that glyphosate causes breast cancer and about a Séralini study (now retracted) claiming GMOs caused cancer in rats, among others.
We know that consumers have concerns, so we reached out to Dr. Kevin Folta, University of Florida interim chairman and associate professor, Horticultural Sciences Department, for an answer. "The short answer is no, there is absolutely zero reputable evidence that GMO foods cause cancer," he writes.
Additionally, the health and safety of GMOs have been validated by many independent scientists and organizations around the world. For example, there are over 1,080 studies about the health and safety of GMOs, and a decade of GMO research, funded by the European Union, that finds that GMOs pose no greater risk than their conventional counterparts can be found here: http://ec.europa.eu/research/biosociety/pdf/a_decade_of_eu-funded_gmo_research.pdf.
In addition to Dr. Folta’s response, this study reviews seven cohort studies and 14 case studies and finds that there is “no consistent pattern of positive associations indicating a causal relationship between total cancer (in adults or children) or any site-specific cancer and exposure to glyphosate.”

- If Glycophosphate (ROUND UP) is so safe why are there more and more articles by Scientists saying it causes cancer, birth defects and so on? If it is so safe why is it banned in many countries? Do you deny that scientists are saying these things, or are only Monsanto scientists smart enough to know it is safe/unsafe?
