10 Genetically Modified Foods

Genetically modified organisms have been at the center of a lot of stormy debates for the past few decades. On the one hand, advocates say the genetic modification is one of the best ways to fight world hunger. As the human population is expected to reach seven billion this decade, malnutrition is a growing global problem.

However, transgenic crops and livestock are not the new Green Revolution. Industrialized farming has resulted in decreased biodiversity, increased use of pesticides, climate change, and polluted water supplies. The introduction of genetically modified (GM) crops will hardly alleviate these problems, and are more likely, according to some activists, to exacerbate them. In addition, GM crops are owned and patented by those who created them, like agri-tech giant Monsanto (once voted the most evil corporation in the world), who enforce their patents through legal action against any farmer they suspect of ‘biopiracy’.

Currently, the USDA and FDA does not require GM foods to be labeled. This list has been put together in the hopes that it will help concerned consumers avoid hidden GMOs.

Maize (Corn)

Corn, soybeans, and cotton are the top three GM crops. Monsanto has two transgenic maize breeds: one of which has DNA from a pesticidal bacteria spliced into it, which makes it resistant to pests, and another that is resistant to the herbicide Roundup, a trademarked Monsanto brand. The herbicide-resistant plants allow farmers to spray their entire fields with Roundup without adversely affecting their crops. (And encouraging the growth of superweeds, but who’s keeping track?)

Nearly all of the corn grown in the US is genetically modified: in 2009, transgenic corn accounted for 86% of the total US crop, and 26% of all corn grown worldwide. Corn is used in a huge variety of products: aside from the obvious offenders like corn flakes, polenta, grits, and meal, corn is used to make a variety of starches and sugars that appear in processed food. GM corn is also used as livestock feed.
Roundup Ready crops have been found to contain residues of the deadly herbicide. Few studies have been done on the toxicity of GM maize, and concerned consumers are forced to wonder why the FDA is gambling with our health on untested crops. 


Soy

Worldwide, soybeans are the most prevalent GM crop. 77% of the worldwide soy crop is genetically modified. In the US, the rate is closer to 91%.
Soy is found in almost every processed food, under various guises including: hydrogenated oils, lecithin, emulsifiers, tocopherol (a vitamin E supplement) and proteins. In addition, soy products are prevalent in more obvious forms like tofu, soy sauce, tempeh, and soy milk. This is bad news for those with a soy allergy, one of the most common food-based allergies.

Two different studies by biologists in the Russian Academy of Science, Alexey Surov and Irina Ermakova, showed that GM soy had some scary side effects on mammals, including low birth rates, high infant death rates, retarded growth, delayed sexual maturity, and high rates of sterility. In Surov’s study, there was even a high incidence of congenital birth defects among subsequent generations, all of whom were fed on a diet high in GM soy. 
 


Cotton

Surprisingly, the third most prevalent GM crop in the world isn’t another grain, it’s cotton. Nearly half of all cotton grown worldwide is genetically engineered to be pest resistant. India has nearly 10 million hectares (about 38,600 square miles, slightly larger than the state of Maine) devoted to growing GM cotton.

Navdanya, an organization created by Dr. Vandana Shiva, carried out a study that showed Monsanto’s GM cotton crops degraded soil health, killing off endemic microbes and decreasing the overall fertility of the soil. In addition, and despite being engineered to resist pests, farmers have been forced to resort to heavy spraying after insects bred resistance to the BT strains spliced into GM cotton’s genetic structure.

Papaya

Another rising GM crop, increasing numbers of GM papaya have been planted in response to the Papaya Ringspot Virus, which nearly halted Hawaiian papaya production in the 90’s. Since then, GM papayas account for about three quarters of Hawaii’s papaya crop. This is despite the fact that the papayas contain a known allergen. The EPA and FDA granted the allergen (a string of amino acids, to be precise, from the original ringspot virus) an “an exemption from the requirement of tolerance”, which translates to, in the words of Joe Cumin of the Institute of Science In Society, an exemption “ from safety assessment, based on the belief that the material was safe for consumption by humans and animals.”

Based on the success of the Hawaiian crop, several countries in SE Asia have been developing their own versions of transgenic papayas. None have yet been approved for unregulated growing or human consumption, but that hasn’t stopped them from cross contaminating orchards in Thailand. Just something to keep in mind the next time you order a smoothie. 


Canola

Canola is a cultivar of the badly named rapeseed, grown principally in the US and Canada, which between them produce between 7 and 10 million tons of seed per year. The plant is grown principally for its oil, which is used for cooking and in other products such as newspaper inks, candles, industrial lubricants, and biofuels. The grist, a byproduct from oil production, is used as animal feed, particularly for pigs.

In the last few years, it has also become a weed. Last year, researchers in North Dakota found feral canola plants growing on roadsides and in ditches, sometimes far from any planted fields, where such an escape might be explained as an accident. As much as 86% of the plants tested were genetically modified. Moreover, some of the plants had interbred, resulting in plants with “stacked traits”.

The feral plants prove that GMOs are capable of competing in the wild. What happens when crops are modified to become hardier, or more resistant to drought or cold temperatures? Invasive and introduced species are already one of the leading causes of extinctions. Plants will inevitably escape their fields.

Monsanto’s response was typically blasé: after pooh-poohing the implications of their escaped plants interbreeding in the wild, they said, “It has never been Monsanto policy nor will it be to exercise patent rights where trace amounts of our patented seeds or traits are present in a farmer’s fields as a result of inadvertent means.”

Really? We beg to differ.

Sugar Beets

Sugar beets, as their name suggests, contain high levels of sucrose and are grown principally for sugar production. About 45% of the world’s sugar originates from their white, lumpy roots.

Monsanto introduced their patented herbicide-resistant sugar beets to the market in 2006, and by 2008, RoundupReady sugar beets accounted for 95% of the American crop. In January of 2008, a group including the Center for Food Safety, Organic Seed Alliance, Sierra Club, and High Mowing Seeds jointly filed suit against the USDA, claiming that the agency had deregulated production of the GMOs without exploring potential environmental impacts. In August of 2010, the judge found in favor of the plaintiffs, and effectively banned production of new plants.

The problem with this plan was that within four short years, Monsanto had killed off almost all competition, becoming the main supplier in the US by a long shot. The USDA defied the judge’s decision, and as of February of this year, is allowing farmers to plant the GM beets.

Alfalfa

Alalfa is grown around the world, mostly as forage for dairy cows. It’s also used as bee pasture, and the shoots are consumed as table vegetables. Unlike most fodder plants, alfalfa is a perennial, and can provide a perpetual grazing ground for years. As a nitrogen-fixing plant, alfalfa can be used as a cover crop or as green manure on fields.

In 2005, Monsanto introduced its herbicide-resistant GM alfalfa. It was planted for two years before The Center for Food Safety and Geertson Seed Farm filed a lawsuit against the corporate giant. A judge ordered an injunction to keep farmers from planting the GM alfalfa, until the USDA issued a full Environmental Impact Statement. The Supreme Court later overturned the ban in favor of Monsanto, but the USDA was still forced to research the full possible effects of the GM crop before. More importantly, the judges agreed that cross-contamination of GM crops was a serious issue affecting farmers and consumers. 


Golden Rice

Golden Rice is the poster child for the GM foods movement. Created by a Ingo Potrykus of the Swiss Federal Institute of Technology and Peter Beyer of the University of Freiburg in Germany, Golden Rice is a cultivar of white Asian rice, modified to have more vitamin A. It was designed and is marketed as a humanitarian tool, created to combat vitamin A deficiencies in developing countries.

Except it doesn’t. For one thing, the current amount of vitamin A in Golden Rice will not actually alleviate the widespread deficiency that’s endemic to poverty-stricken areas. Secondly, as activist Vandana Shiva points out: “The reason there is vitamin A deficiency in India, in spite of the rich biodiversity and an indigenous knowledge base in India, is because the Green Revolution technologies wiped out biodiversity by converting mixed cropping systems to monocultures of wheat and rice, and by spreading the use of herbicides which destroy field greens.”

Malnutrition is not just a matter of food: it’s a problem with roots in poverty, lack of education, and social unrest. Genetic modification of crops is not the answer. 
 


Salmon

Remember the rumor that KFC’s name change was spawned by their use of mutant Frankenstein chickens? While that may have just been an urban legend, transgenic livestock is definitely on its way to supermarket shelves.

The closest to getting approval is the AquaAdvantage® salmon, which has been genetically engineered to grow to market size in half the time it normally takes. Recently, the company behind the GM salmon applied to the USDA for the fish to be deregulated, making them available for commercial farming. The company, the Massachussets-based AquaBounty, has guaranteed that there is minimal chances of the fish escaping into the wild, and — because the fish are effectively sterile — almost none of them interbreeding with wild salmon populations.

Consumer groups, animal welfare organizations, environmentalists, and lawmakers have already formed a coalition to fight against the genetically engineered fish, citing concerns for consumers’ health, the environment, and wild salmon populations. There are currently two bipartisan bills being introduced in Congress. Senator Patty Murray, a democrat from Washington state who is cosponsoring the bill, said, “I do not want to see FDA rush through a rule that can undermine our economy and this important resource for Washington state – and actually for the world – without very thoughtful, smart decisions.” 


Pigs

The genetics of livestock and other animals have already been altered in efforts to produce organs for human transplants. More recently, Canadian scientists have created a more environmentally friendly pig.

The Enviropigs, as they’ve come to be called, have had DNA from mice and E. coli bacteria spliced into their genes. The animals produce less polluting phosphorus in their manure, which makes it safer to use as a fertilizer. Phosphorus is responsible for creating algal blooms that create vast “dead zones” in bodies of water that are void of life.

However, it’s not the pig’s genetics that’s the real problem, here. It’s commercial hog farming. Raising thousands of animals in small spaces is never going to be environmentally friendly, Enviropigs are just another example of biotechnology trying to fix the symptoms instead of the cause.

Andrew Kimbrell, the director of the Center for Food Safety, summed it up nicely: “It’s a completely novel cell invasion technology where we are crossing the boundaries of nature as no other generation has before. And the question is whether that is safe, whether that is something that we should be doing ethically, those are very serious questions that we as a society need to be asking.”

  • I enjoyed your article on the Genetically Modified problems that our society faces at this time.Unfortunately this is a science that is not going to go away anytime soon. With the way the world food production, with it’s unfriendly mindset to sustained production organically,is moving to more production and be damned the consequences to the environment. As your article points out we had better be very knowledgeable and sure of the outcome down the road.Personally I will not eat processed meat, fish or vegetables. My family and I have been eating wild meat, fish and poultry for over 35 years. If I don’t harvest it I don’t eat it. If more people got the knowledge of how to raise their own vegetables, even in tight urban spaces, the benefits would be tremendous, socially, economically and health wise. More education is needed and more articles like yours to open the eyes of the general public. Thanks for listening.

    The only way to avoid gmo food is to grow it yourself, eat organic, or buy from local farmers so you can ask where they get their seeds. One source of non-gmo food I’ve found is at http://healthystoragefood.com. Very tasty and it has the ability to store for future use.
