This Is A GMO.

By Heidi Muller October 6, 2011

what is a GMO?

At least, I think so.  After 3 hours spent studying the seed packet that came with an 8-page usage and warning label, finding definitions of the multi-syllable words I’d never heard of, visiting the website of the company that produced this seed, being led to subsidiary company websites, trying to translate all the corporate-speak that exists on these sites, looking up all the information possible about the fungicide that coated the outside of every seed in the packet . . . . . I cannot definitively say this is a genetically modified organism.

All indications point to yes, the seed that produced this purple pepper was genetically modified.  But in the United States, seed companies and food producers are not required to tell us that.  So why would they?

What is a GMO, anyway?

From Wikipedia: A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known as recombinant DNA technology, use DNA molecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes.  The general principle of producing a GMO is to add new genetic material into an organism’s genome.

It’s worth noting that genetically modifying is much different from cross-pollinating, which has been going on since the dawn of time.   A perfect example of cross-pollination? You.  Your mother cross-pollinated (wink, wink) with your dad, their DNA came together, and 9 months later you arrived on the scene.  They hoped you’d get your mother’s nose and your father’s common sense . . . but they got what they got, and you all have to live with it.   It’s important to note that your parents were both human.  Cross-pollination only occurs within the same species.

In the plant world, there’s no sex.  Alas, there are bees.  Bees take pollen from the male flower and deliver it to the female flower.  They also deliver pollen from everything else they’ve stepped on during their route, but the female flower manages to use only the pollen from the male flower of her species.  Cross-pollination certainly occurs naturally, but it can also occur with a farmer and a paintbrush.  The paintbrush collects pollen from the male flower of a plant, the farmer carries it to female flower and drops it off.  The farmer marks that flower, and when it produces a fruit, the seeds inside are saved and planted the next season.  Here’s where the process differs from people:  let’s estimate the fruit has 100 seeds.  The farmer plants all 100 seeds — from this, all possible combinations of genes will present themselves (If you ever had to suffer through a probability section in a math class, you had this math problem.  How many recessive/recessive gene plants can the farmer expect to get?).  The farmer will find the plants that have his/her favorite attributes of the parent plants, and will save seeds from those plants for the next year.

GMO’s are controversial because they usually combine genetic material from different species, which is unnatural.

So why should we care if something is genetically modified?

Genetic engineering is in the process of creating ‘bananas that produce human vaccines against infectious diseases such as hepatitis B; fish that mature more quickly; cows that are resistant to bovine spongiform encephalopathy (mad cow disease); fruit and nut trees that yield years earlier, and plants that produce new plastics with unique properties.’ (source article)

According to the producers of  GM seeds, the results of their engineering produce higher yields, more nutrients, improved resistance to disease and pests, and reduced maturation time.  That seems good, right?

But.

What is a GMO

The safety of GMOs is still up in the air – there is evidence GMOs are harming the soil microbes that help us grow food.  There’s also evidence they are causing new allergens and pathogens in people.  Unintended transfer of GMOs through natural cross-pollination is creating a loss of biodiversity.  And, many are more concerned about effects that are still unknown.  The side effects of GMOs to soil, plant, animal and human life has yet to be studied in depth.

There are ethical issues.  Seeds have always been owned by no one – in fact, most of the plants we eat originally came from some of the poorest countries in the world.  If all seeds become GMOs, the entire world food supply will be controlled by a few companies.  Poor countries will be even more dependent on industrialized, rich countries.  Plus, tampering with the intrinsic values of plants and animals just seems wrong to a lot of people.  We’re messing with nature.

The pepper I grew from (likely) GMO seed  is sitting in the fridge.  After all the research I’ve done on its behalf, I can’t bring myself to taste it.  I probably eat GMOs every day in the foods I buy at the grocery store . . although there’s no way for me to find out what those items are.

There is a grassroots movement in the United States that is calling for all products containing GMOs to be labeled as such.  If you are interested in getting involved, visit justlabelit.org to send an email to the FDA.

Where do you stand on GMOs?

Are GMO Foods Safe To Eat?

By Tim Lymberopoulos February 19, 2011 4 Comments

Before I begin, I am not a lawyer, and I’m definitely not going to argue against any large biotech firm’s legal team on whether GMOs are safe. But, I am very interested in this issue and am trying to shed light on a great question.

The answer, however, is more difficult and involves asking more questions. Are GMO foods safe for people? For animals? In the short term? What about the long run? How do you trace an illness to a GMO? Could a disease take a long time to develop? (The last question is a great discussion in a smoke-free coffee shop).

Here is what Monsanto says on their website: “Yes, food derived from authorized genetically-modified (GM) crops is as safe as conventional (non-GM-derived) food. There has not been a single substantiated instance of illness or harm associated with GM crops.”1

That’s great, but sometimes we state things we believe to be true only to find out later we were wrong.

Here is an article from Time Magazine from April 24, 1950.  “…DDT is practically harmless to humans who get it on their skins or breathe it into their lungs. The two officers examined military personnel and laborers who had been working with DDT for as much as five years. In no case did they find an ailment traceable to DDT.” 2 (Please read the article.)

Let’s go back to Bt Corn. (What is Bt corn?) StarLink corn has a genetically modified gene that produces a protein that is toxic to insect pests. Therefore, this corn makes its own pesticide. StarLink received governmental approval for domestic animal feed and biofuels, but not for human consumption.3 The reason was because this toxin protein that killed insects was found to be an allergen to humans. Two years after its release, it was found in taco shells made by Taco Bell.  StarLink corn was discontinued.

Currently, there are no human trials being conducted by any large biotech firms. Here is what Monsanto says on their site: “It is impossible to design a long-term safety test in humans, which would require, for example, intake of large amounts of a particular GM product over a very large portion of the human life span.” I disagree — read my first post on GMO foods.

We don’t know the answer to this question because this technology has only been around a few decades. The building blocks of the human body are proteins. Proteins we have been ingested for centuries. Now, we are consuming new proteins that have only been tested in animals for less than one generation.

We will continue this conversation here on our blog and touch on many more issues surrounding GMO foods.

We encourage you to participate in our conversation. Do you think genetically modified food is safe? Do you think there should be a label that identifies GMO foods?

The Biggest Experiment in Human History

The biggest experiment in human history is occurring right in front of our eyes, and nearly everyone participating doesn’t even know it is happening.

Yes, we Americans are the guinea pigs for testing something called genetically modified organisms (GMOs).

What is a GMO? We will provide two definitions.

According to Monsanto, a biotech seed producer, GMOs are the result of the following process:

Biotechnology, or genetic engineering, is the process of inserting a gene from one species, like a plant or a bacterium, into another species. Typically the gene inserted will express an advantageous characteristic in the plant, such as the ability to tolerate environmental pressures, like insect resistance or drought tolerance.1

According to The Non-GMO Project:

GMOs are organisms that have been created through the gene-splicing techniques of biotechnology. This relatively new science allows DNA from one species to be injected into another species in a laboratory, creating combinations of plant, animal, bacteria, and viral genes that do not occur in nature or through traditional crossbreeding methods.2

For centuries, humans have been manipulating the traits of plants and animals using crossbreeding techniques. But there are significant differences between crossbreeding and engineering GMOs.

Crossbreeding is the ‘crossing’ of closely related species to produce new desirable properties. Dogs are an example of this. Breeders take the trait of  a certain dog and cross it with another to get the desired results. For example, you take a bulldog and cross it with Shih Tzu and you get … (I couldn’t resist). The key point here is that crossbreeding can take place naturally.

GMOs are the result of injecting the gene from one species into another completely different species through scientific human intervention. It’s like taking a gene from a jelly fish that glows in the dark and putting it in a zebra fish. The GMO is a GloFish® (notice the trademark).3 This cannot occur naturally.

GMOs are commonly used in food production. Let’s look at one in particular. Corn. I grew up in Princeton, Ill., which is surround by corn.  The next time you fly in a plane over the Midwest, look out the window, and you’ll see endless rows of corn. In 2000, the corn fields in Illinois contained 17 percent genetically modified corn.  In 2010, over 85 percent of all that corn was genetically modified.4 Wow! OK, but who eats that corn? We all do. From Los Angeles to New York City.

In 10 years, nearly all of our corn has changed from natural to genetically modified. And this is just one small part of this important topic. Why are we writing about GMOs? Because Americans are the test subjects, and I think it is prudent for us to learn about this experiment and its implications. Hence our series on GMOs.
