GENETICALLY MODIFIED FOODS 2
Abstract
This paper examines genetically modified (GM) foods. The science and distribution of these
products will be discussed as well as the positive and negative concerns that arise with
genetically engineered (GE) products. The ethical issue of not labeling GM products will be
examined from a pro-versus-con view. Finally, the paper will explore both sides in the great
debate between supporters and detractors of labeling laws in the United States for GM products.
Keywords: genetically modified, genetically engineered

Genetically Modified Foods:
The Good, the Bad & the Ethically Wrong
Shopping at a grocery store can be overwhelming because of the abundance of available
products. For individuals choosing to avoid processed foods or foods that have been genetically
modified (GM) it can be even more challenging. When a consumer is shopping in the produce
section they have to be incredibly educated on what to look for in a product if it has been altered.
Genetically changed fruits and vegetables are not thirty feet tall nor do they have unusual
powers; they look exactly the same as produce that has been grown with traditional fertilizers
and pesticides or an organic fruit or vegetable. GM produce can be hard to pick out because most
of the time it is not labeled, mostly unpackaged and mixed in with other produce. So why are
these labels absent? Is there any legislation at all? These questions are coming more to the
forefront of shoppers’ minds as people are educated on genetically modified foods. There is
currently little regulation on food labeling requirements on products that are genetically
engineered (GE) in this country. Many have been fighting a “right to know” campaign in an
effort to make labeling these foods a requirement and not an option.
We have been consuming GM products for over 20 years. The first GE crop that was
available on the market was the tomato in 1994, but the product was no longer sold in 1998, due
to not meeting certain expectations (gmocompass.org, 2006). GM crops that are currently grown
in the United States include corn, soybean, cotton, canola, sugarbeet, alfalfa, papaya and squash
(ISAAA, 2013). Not only are these products sold separately, but they are also used in processed
foods and feed for animals. Consumers are purchasing products with little to no information on
where their food supply is coming from. The nation is at a crossroads on this issue. Is it ethically
GENETICALLY MODIFIED FOODS 4
right that our food continues to be modified without our consent? Is it acceptable that the
majority of people are consuming genetically altered products without realizing it?
The Science of GM Foods
So what actually makes our food supply genetically modified? Like humans all plants
and animals contain cells with a nucleus that holds our DNA. When the genetic makeup of
animals, plants or bacteria is altered these organisms are then considered to be genetically
modified (CSIRO, 2011). One way to achieve this is through GM breeding, which involves
combining different genes from different organisms (CSIRO, 2011). For example, GM cotton
uses a gene from a bacteria that is naturally resistant to insects (CSIRO, 2011). In Australia
pesticide use was reduced by 80 percent when combing the cotton and bacterial gene (CSIRO,
2011). Gene splicing, gene silencing and bacterial carriers are other common techniques that are
used in genetic modification. The use of genome sequencing has helped lead scientists to
discover traits that can allow for optimal growth in plants and animals. By changing the genetic
makeup of the organism you can alter various traits, i.e. taste, color, shape and disease resistance
(ISAAA, 2013). In 1996, the first insect-resistant crops were introduced to the world, changing
agriculture as we know it (USDA ERS, 2012). It is no surprise that most research on GM crops
has been conducted in developed countries, but developing countries have the capability for GE
as well (ISAAA, 2013). In 2013, 27 countries elected to plant biotech crops, surprisingly only
eight were industrialized countries and the rest were developing (ISAAA, 2013). Their
popularity is astounding. From 1996 to 2013 GM crop hectares have increased from 1.7 million
to 175 million hectares (ISAAA, 2013).
The Positive Aspects of GM Foods
GENETICALLY MODIFIED FOODS 5
GM products can actually be beneficial and provide added health benefits to our diet. For
starters, they can be altered to have a higher nutritional content. For example, increased levels of
beta-carotene could be added to help with Vitamin A deficiencies (findourcommonground.com,
2014). Underdeveloped countries can benefit from this because their daily nutrient content is
seldom met. GM foods can also be enhanced to improve the quality and taste of foods. Fruits and
vegetables that have been modified will stay fresh longer than traditionally grown produce
(findourcommonground.com, 2014).
GM foods can have a significant global impact. In 2013, the world had 7.1 billion
people, this number could rise to more than 9.5 billion by the year 2050 (prb.org, 2013). How
can we possibly keep up with the world’s food supply with the population increasing so rapidly?
Because GM foods have the ability to be mass produced they can prevent and/or decrease the
global food crisis. This in turn will give countries increased food security. GM crops can also be
engineered to grow in special environments, thus developing countries would be able to grow
more crops which would allow for their economy to grow as well (findourcommonground.com,
2014). Iowa State University claims that global food prices could increase 10 percent for
soybeans and up to six percent for corn if GE was not available (findourcommonground.com,
2014).
There are many environmental benefits that are associated with producing GM crops. It is
estimated that 30 percent of crops are lost even before harvest due to pests (Mckie, 2012). Not to
mention the reported cases of pesticide poisoning in agriculture workers can be anywhere from
10,000 to 20,000 cases annually (Phipps & Park, 2002). Having crops that are genetically altered
can change this because GM crops can reduce pesticide use. In 2000, GM cotton reduced
pesticide use by a total of 22.3 million kg (park, 2002). By not using pesticides workers will
GENETICALLY MODIFIED FOODS 6
further avoid contaminating groundwater. Not using the machinery to spray the crops with
pesticides could salvage 20.5 million liters of diesel and could lead to a reduction of 73,000 tons
of carbon dioxide into our atmosphere (Phipps et al, 2002). GM foods are promising because
they reduce the carbon footprint, but they can also be damaging.
The Negative Aspects of GM Foods
Globally, GM products sound beneficial but in reality we are further broadening the
economic gap between developed countries and developing countries because of this advanced
technology (ISAAA, 2013). Developing countries will devote more money to GE than to
technologies that would better benefit their country’s economic status. The health risks
associated with GM foods are also still unclear, but autism, reproductive disorders and digestive
problems have been on the rise since GM crops were introduced (responsibletechnology.org,
2013). It is believed that GM foods can be introducing allergens and other anti-nutrition factors
in foods if not careful (ISAAA, 2013). The World Health Organization States (2013), “the
transfer of genes from commonly allergenic foods is discouraged unless it can be demonstrated
that the protein product of the transferred gene is not allergenic” (concern for human health, para
2). Although, the possibility is extremely low another concern is antibiotic resistance (gmo
compass, 2006).
There are also crop issues that could occur. Crop issues that could happen include toxins
from GM crops affecting organisms that were not supposed to be targeted (ISAAA, 2013). From
an environmental standpoint we could be harming the susceptibility of other organisms that do
not affect the crop. For example, the monarch butterflies population has decreased by 50 percent
because its habitat is being destroyed by the GM crops herbicide roundup
(responsibletechnology.org, 2013). Most importantly, GMOs contaminate the environment
GENETICALLY MODIFIED FOODS 7
indefinitely. Once they are cross pollinated it will be nearly impossible to make the strains pure
again (responsibletechnology.org, 2013). Organic farmers are currently having a difficult time
keeping their seeds pure for this reason.
Government Regulation of GM Products
Government regulation currently varies from country to country (WHO, 2013). The
countries that currently do have regulation on GM foods focus their efforts on assessing the risks
for their consumers’ health (WHO, 2013). The World Health Organization states (2013) that
“countries’ legislation typically regulates GMOs in general, taking into account health and
environmental risks, as well as control-and trade-related issues e.g. labeling and testing” (gm
foods regulated nationally, para.1). So what is the United States government doing to protect its
citizens from GM products? The United States is one of the most developed and technologically
advanced countries in the world, yet it still has not mandated a nationwide labeling or ban of GM
products. Below is a map showing what countries currently require labeling or have even banned
GMOs.
GENETICALLY MODIFIED FOODS 8

Currently, in the United States the Food and Drug Administration gives manufacturers
the option to provide voluntary labeling if their product is engineered (FDA.gov, 2014). For the
companies that label their product, how do you know if it is genetically modified? It is not like
they place a big red sticker on their produce that says “I’m a GMO.” One way is to look at the
price lookup number or PLU code on the sticker (Lipman, 2002). If the product only contains
four numbers in its PLU code then it was grown traditionally with herbicides and pesticides, but
was not genetically altered (Lipman, 2002). If the product contains five numbers and begins with
the number eight then the produce is a GM product, and if the produce contains five numbers and
begins with a nine then the product is organic (Lipman, 2002).
The Ethical Debate Concerning Labeling Requirements
GENETICALLY MODIFIED FOODS 9
There is growing negative stigma attached to genetically altered foods in the minds of
consumers. Many people feel it is not ethically right to not label genetically engineered products
without being informed of the changes. You would think that labeling a product would not be
that difficult and everyone would be in agreement, yet there are individuals that are in strong
opposition of requiring the products to be labeled.
Pro-Labeling GM Products
There are 64 countries that require labeling, but the United States is not one of them
(labelgmos.org, n.d). American citizens feel they have the right to know what is in their food
supply even if they do not fully understand the ingredients. A 2010 healthcare survey found that
93 percent of Americans believed there should be GMO labeling requirements and because of
this there has been a huge push for the right to know (gmo.org, n.d). As of now, states are the
deciding factor in voting and passing legislation.
Connecticut was the first state to pass the requirement for GM food labeling (Simon,
2013). The map below shows states in blue that currently have legislation in process and states in
green who have successfully passed some form of legislation (righttoknow.org, 2013).
GENETICALLY MODIFIED FOODS 10
http://www.righttoknow-gmo.org/states
In 2011, a poll showed that GM labeling was supported by 89 percent of Republicans and 93
percent of Democrats (righttoknow.org, 2013). So why does legislation continue to fail when
bills are brought up on labeling requirements? Sadly, the main reason is money.
Anti-Labeling GM Products
Companies like The Grocery Manufacturers Association are in strong opposition of
labeling GMOs. They actually donated $11 million dollars in the 2013 elections to help
compress labeling efforts (Andrews, 2014). The Grocery Manufacturers Association claims that
labeling is not necessary since there has yet to be any hard evidence that GM products are indeed
bad for our health, yet 64 other countries require labeling (labelgmos.org, n.d). Other major
corporations invested in the opposition of labeling include PepsiCo, Coca-Cola, Nestle, General
Mills, Campbells, Hersheys, Del Monte and Kelloggs (inspirationgreen.com, n.d). Most would
GENETICALLY MODIFIED FOODS 11
find it surprising that these companies also have millions of dollars invested in the production of
organic produce. If labeling laws are to be mandated then a new problem would arise within the
organic community. The USDA organic label would have to worry about competing with non-
GMO labels. A consumer who is choosing to eat cleaner might opt to pick the non-GMO product
because it will still be cheaper than organic. If they are uneducated about the way their food is
grown they might not realize that their food still contains pesticides and fertilizers. At least now
people who are choosing to avoid GM foods naturally gravitate toward organic because non-
GMO is not labeled yet. Currently, it is a win-win for these huge corporations. People are eating
GM foods without realizing it and they are consuming organic produce.
Advocates for GM products also feel the cost of labeling could actually make our food
costs increase by 10 percent (McWilliams, 2014). It is not the labeling that will actually be
expensive but the enforcement of compliance and segregating GM seed from non-GM seed
(McWilliams, 2014). According to McWilliams (2014), “85 percent of U.S. corn, 95 percent of
U.S. sugar beets and canola and 91 percent of U.S. soy are genetically modified” (para. 9). Even
harder to segregate would be processed foods since up to 75 percent contain at least some form
of genetically changed ingredient (McWilliams, 2014). When GM advocates mention the cost of
food increasing then consumer support drops and they become willing to vote no for labeling
requirements. Once again it all comes back to money.
Conclusion and Future of GM Products
People have different values and beliefs toward food. Some cultures even assign religious
significance to what they eat. It is not surprising then that labeling GM products has become a
hot-button ethical issue. The future of GM products and labeling still remains unclear. One goal
for the future is to produce GM crops with enhanced vitamins, minerals and fatty acids to help
GENETICALLY MODIFIED FOODS 12
combat chronic diseases like diabetes, heart disease, obesity and even cancer (gmocompass.org,
2006). Monsanto is working on DroughtGard, which is a hybrid corn that can still grow even
when water is scarce (Stecker, 2012). This can allow for less irrigation in times of drought, and
could save millions of gallons of water every year. In retrospect genetically engineered products
sound like the answer to help the global food crisis and become healthier. The problem is we
really have no idea what future damage is being done to our bodies due to eating these products
now. It is clear that GM foods have the potential to be good and bad for us in many different
ways. Whether it has to do with our health, our economic status or something as seemingly
simple as customer education on a product, labeling for GM foods has become an ethical issue
that will not subside until labeling is mandated or the product is banned.
