The manipulation of organisms by genetic engineering is tinkering with Mother Nature on a very deep level, and the consequences are far reaching and serious for humans, plants, animals, and the planet.
Walk with me while I help you understand this phenomenon, learn the real concerns about GMOs, and gear up to protect yourself and your animals from harm.
GMOs: What They Are
GMO stands for genetically modified organism. Other acronyms used to describe the same entities include GE (genetically engineered so-and-so) and GM foods or GM crops, etc.
What sets GMOs apart is the manipulation of an organism’s actual DNA in a laboratory, by the insertion of another species’ genes into the gene sequence of the target organism.
- The commonest example of GMOs is made by inserting bacterial genes of herbicide resistance into a crop plant. This is most often done by inserting genes of resistance to Roundup (glyphosate, the commonest herbicide in use on the planet, brought to you by Monsanto).
An example would be growing a GMO soy crop with herbicide resistance. “Roundup Ready” soy varieties allow a farmer to blanket his soybean field with glyphosate, and thereby kill all the weeds without killing his crop.
HR or herbicide resistant crops account for 85% of the GE planted acres in the world today, and most are “Roundup Ready” crops.
On the horizon are GE crops resistant to even more dangerous herbicides, like 2,4-D, the chief ingredient in Agent Orange that damaged so many people in Viet Nam.
Well, as you may have guessed, resistance to Roundup is appearing in weeds, so we now have “superweeds,” much like the superbugs in hospitals from society’s overuse of antibiotics.
Natural resistance like this is nothing new. Treat any population with a chemical and a few will resist it, breed, and make more resistant offspring who can laugh at the oncoming chemical.
Bacteria, insects, weeds, parasites, they all do this in Nature. Did Big Ag miss the memo on that?
- The second common class of GMOs results from the insertion of a bacterial gene that makes a pesticide into the target crop’s genes. This is most commonly the bacteria called Bt, Bacillus thuringiensis, which elaborates a chemical that kills insect larvae.
So, GMO corn that has the Bt gene inserted into it will theoretically now resist corn borers, the larva that crawl in the tassel end of the cob and munch away, damaging the crop. After a taste or two, the larva die from eating the Bt toxin that’s now part of the corn plant.
Wondering what eating such a toxin laced crop would do to the eater, say the cow? Or your dog who eats that GMO corn in his kibble, or your horse in her sweet feed?
How about your dog who eats the cow who ate the GMO corn with the toxin built in?
How about you and your husband eating that cow? Or drinking her milk?
In fact, problems abound from non-target species eating the Bt toxins. More on that later.
GMOs: What They Are Not
Astrophysicist Neil DeGrasse Tyson got this wrong, and he’s touted as a genius in his field. I’ll help you avoid making the same mistake. No PhD required.
Neil confused plant breeding or genetic selection with GMOs. Said we’ve been using GMO for tens of thousands of years.
A couple of decades is much closer to reality, Neil.
Putting his foot squarely in his mouth, Neil told the folks concerned with GMOs to “chill out.” His message went all over the internet, adding to the confusion about GMOs (that Big Ag spins for profit), and fueling the anti-labeling forces bent on keeping us in the dark about what’s in our food.
Here’s expert Jeffrey M. Smith straightening Neil out in three minutes. Trust me: you’ll want to watch it.
And if you really want to dig deeper and learn even more, here’s Jeffrey Smith’s detailed Part 2 to Neil.
In it, he cites work done in Canada showing that 93% of a test group of pregnant women had Bt toxin in their blood. The scientists who presented this data suggest the source of Canadian women’s Bt toxin load was their regular consumption of milk and meat from animals who fed on GMO crops.
Slow and Thoughtful vs Quick and Dirty
Genetic selection has a history of thousands of years, and it happens both naturally and by man’s choosing which plants or animals to breed with one another.
It’s how we’ve started with dogs who looked like wolves and ended up with breeds who look nothing like wolves, to whit, Cocker Spaniels, Pugs, and French Bulldogs.
Man’s genetic selection, like the natural selection that Darwin brought to light, is a slow process. It’s how we went from ancestral maize (which was pretty much inedible unless ground and mixed with lime and cooked in various ways) to sweet corn that’s delicious even eaten raw on the cob.
Scientists Blew it With Wheat, Long Before GMOs. Can We Trust Them with GE?
Not to say that everything genetically selected has been a blessing to mankind. Far from it.
The “green revolution” of the 60s, which set out to feed the world’s starving masses, hybridized wheat to produce ten times more yield per acre. In so doing, the nutritional composition of wheat unintentionally changed dramatically.
Small changes in the protein of wheat during this race to increase yield now provoke an immune response in the wheat eater that was never there in Grandma’s day. I know this one personally. If I eat today’s modern wheat in any form, within eight hours I get stiff joints that often last for 24 hours or more. Damn. No more pasta and sandwiches for this guy.
To learn more about these changes and their correlation to the epidemic of modern day obesity, don’t miss Wheat Belly, by Wm. Davis, MD cardiologist. The book is a fascinating read, especially if you’re fighting a runaway waistline.
Bottom line: plant breeding and animal breeding is generally safe and has a long history. GM is far more insidious genetic manipulation that is in its infancy and is already raising grave concerns for the health of people, plants, and animals.
Forcing Nature to Submit
Hubris and greed know no bounds when it comes to Big Ag. Much as Monsanto has railroaded the GM crops to market with “safety studies” that are only 90 days long, and has bankrolled the anti-labeling campaigns in various states to keep consumers in the dark, GMOs are produced with a forced, rapid process compared to natural breeding or hybridization.
One species’ DNA has natural defenses against the introduction of another species’ genetic material. It’s not easy to overcome this defense, so “gene canons” are used to blast the foreign DNA into the cell. (If that sounds a bit like rape to you, well, I’d agree.)
Sometimes, bacteria are used to infect the plant cells and carry in the foreign DNA. Along with the desired genetic material can come unwanted bacteria or viruses. So, antibiotics are often used in the process of making a GM food. And the process is very imprecise, more like a shotgun than a sniper’s rifle, so the potential for unwanted combinations of genes is significant.
Can you say “mutation?”
And mightn’t some unintended gene combinations be harmful to other species, like humans and our animals? Useful question and food for thought. No pun intended.
How Widespread Are GMOs?
In 2013, about 12% of cropland in the world was growing GM crops. The top countries that grow them are:
Current estimates from the Center for Food Safety indicate processed human foods have a 60-70% likelihood of containing GMOs.
Processed food. Sounds a lot like kibble, doesn’t it? Equine pelleted feeds, too.
60-70% is pretty high odds. U.S. acres planted with GM corn or soy have steadily grown in the past dozen years and the GM varieties of the top three crops (corn, soy and cotton) are now all in the 90%-plus range.
To get a sense of how many grocery store processed foods contain some corn, watch the movie King Corn. You’ll be amazed.
Processed food manufacturers are some of the big players spending money to block GMO labeling initiatives in various states. The infamous Grocery Manufacturers of America (GMA), representing hundreds of food makers, has contributed millions of dollars to keep consumers in the dark about which foods contain GMOs.
Wouldn’t you like to know what you’re eating and feeding the animals in your care?
Health Effects of GMO Consumption
Here is a smattering of what’s been associated with GMO crop consumption in animals to date:
- Liver damage and kidney damage (both in rats, Monsanto’s own data). Independent data confirms this and adds heart, spleen, adrenal glands, and blood producing organs to the list of damage in rats fed GMOs.
- Reproductive failure (miscarriage and infertility). Enlarged uteri in pigs fed GMO for 23 weeks.
- Stomach inflammation in those same pigs cited above.
- Gut flora disruption. We know how important they are, right?
- Hormone dysregulation, including insulin. Another cause of our obesity epidemic?
This is enough to be very concerned about eating or feeding GMOs, and it’s the tip of the iceberg. There are more known health concerns than those listed here, but far more is unknown, as the whole field of GE is so new.
I guess Big Ag missed the memo on the Precautionary Principle as well. Shame on them. Now we’ve got to clean up their mess and live with their poisons, unleashed in the name of Profit Above All Else.
Agricultural Misfires from GMO Use
- More (not less) herbicide use, and stronger herbicides.
- Super weeds that need strong herbicides to kill (and are even more risky to humans, like 2,4-D).
- Resistance in insects.
- Harm to non-target insects, like Monarch butterflies, bees, and other beneficial insects.
- Harm to soil organisms, a key to raising healthy crops.
- No increase in crop yields, counter to what Monsanto would like you to believe.
The huge agribusiness companies who profit from GM sales try desperately to spin the story to make GMOs sound not only harmless, but actually good for you and the planet!
For some evidence based myth busting on GE, with lots of references, here’s an in depth report.
How About Natural Foods? Or Organic Foods?
Consumer Reports went to work testing both, and Reuters picked up the story. It’s an eye opener.
- Foods labeled “natural” (remember that meaningless term, that N word?) were mostly found to contain GMOs.
- Those meeting “organic” standards did not.
So, dear shopper, if you’re out to buy the convenience of prepared foods, for your animals or yourself, and you want to avoid the risks of eating genetically engineered food, you’ll likely be safe buying those foods labeled organic.
For now, at least.
What About Your Animals and GMOs?
You can do a little math and figure this piece out:
- Most of the corn and soy grown is now GMO. Sugar beets, too. Oh, and canola oil.
- Most of the processed (human) food (60-70%) now has GMO ingredients.
- Therefore, if you’re feeding processed pet food or horse feed, and the label includes any corn or soy (or products derived from either), or canola oil or beet derivatives, odds are very high your animals are being exposed to GMOs.
As is often the case, animals are studied to determine if humans might get sick from some new experimental drug or chemical or process. Here are some findings worth taking caution from:
In 2009, the American Academy of Environmental Medicine (AAEM) stated that, “Several animal studies indicate serious health risks associated with genetically modified (GM) food,” including infertility, immune problems, accelerated aging, faulty insulin regulation, and changes in major organs and the gastrointestinal system.
The AAEM has asked physicians to advise all patients to avoid GM foods.
What Do Animals Think of Eating GMO?
- Pigs wouldn’t eat it. You know, those guys who are happy to eat just about anything, including feces? Yeah, those guys. Held out for something else.
- Water buffalo in India won’t eat cottonseed cake that’s GMO.
- Birds refused GMO corn in South Africa. Wildlife, including migratory geese, choose fields that are non-GMO for their in-flight snacks.
- Cows, sheep, buffalo and horses grazing on harvested GMO fields died, their deaths believed to be associated with their GMO consumption.
Not a pretty picture.
Cows and GE Milk
When I was in my latter years of dairy practice in the late 80s, rBGH – recombinant bovine growth hormone – had just come to market from Monsanto. It was one of the first genetically engineered products on the market.
A couple of our big dairies were considering using it, amid public concerns that the health risks to consumers were not well evaluated. (Monsanto had the only data out there: a 90 day study on 30 rats. What is it with Monsanto and these 90 day studies??)
Monsanto then, much like it is doing today with GMOs, fought labeling of rBGH milk with millions of dollars. They ultimately bowed to public pressure. People wanted milk without rBGH, and state governments largely fought off anti-labeling efforts by Monsanto.
Research by independent sources revealed more mastitis, lameness, and deformed calves born to the cows injected with this GE hormone. Today, rBGH is banned in the European Union, Japan, Australia, New Zealand and Canada. It’s still used in the U.S., though milk without it is often labeled.
Monsanto sold the rights to rBGH to Pfizer. Guess they had enough headaches dealing with all the elections they had to buy to stop our GMO labeling.
GE Animals on the Horizon
Yes, it’s not only crops and milk cows that are being tinkered with; there are other animals in the GMO pipeline as well.
- Hogs with more omega 3 fats in their bodies.
- Salmon that grow twice as fast as wild salmon.
- Goats that produce pharmaceuticals in their milk.
In creating GE animals, the new animals are produced by DNA microinjection, and there’s very little control of where that injected DNA ends up in the test animal. When misplaced, genetic defects and deformities are the result.
The survival rate of the process is on the order of 4% or less, bringing up all sorts of animal welfare concerns. And do the animals who “didn’t take” the new DNA properly end up on store shelves for human consumption, genetic defects and all?
What to Do About These Nasties?
Depending on your level of concern with GMOs, here are several things you can do to help avoid harm to you, your animals, and the planet.
- Home prepare your raw food. Don’t know where to start? My friends at Dogs Naturally Magazine will get you started with a free video course in less than an hour (click the name of the magazine to get that free course).
- Avoid processed food like the plague. That’s the stuff in the middle aisles of the grocery store. High likelihood that if you’re buying fresh ingredients and preparing food for yourself and your animals, you’ll be avoiding GMOs. And the opposite is true, as you read above.
- Vote, when given the chance, to require labeling of all GMOs in all foods. This is polling place voting, and Monsanto, DuPont, and the Grocery Manufacturers of America will be throwing money against your efforts. Lots of money. We’ve got to see through that and help others learn and vote for labeling. The big boys know no one will willingly buy GMO tainted foods. They fear your vote to label.
- Akin to #1, vote with your pocketbook. Refuse to buy products made with GMOs, and boycott those GMA companies that are trying to hide GMOs by disallowing their labeling. You have a right to know what’s in the food you buy, don’t you think?
- Buy foods labeled organic, especially if they contain common GMO ingredients, like soy, corn, alfalfa, or sweeteners.
- Join me in joining the Center for Food Safety to keep up with trends in this rapidly changing landscape.
- When shopping, look for verified non-GM foods on the market. Check out the Non-GMO Project for a list.
- For a higher tech solution, get their iPhone app, which’ll scan UPC codes for things you while shopping. (Warning: several products I have in my office didn’t show up in my testing of the app, including my organic Pink Lady apples, Raw Support, my favorite joint supplement, and shelled hemp seed that I put in my smoothies most every day. I know these are all GMO-free, but they just aren’t in the Non-GMO Project’s database yet.)
To help you vote against the Grocery Manufacturers of America (a front group that opposes your right to know what’s GMO), the graphic above shows the companies they represent (who should be ashamed of themselves, and not receive a penny of your hard earned income).
Clicking that poster will bring you to the Cornucopia Institute who’s been been tracking the companies who’ve donated money to either:
- (On the left side) Keep you in the dark by opposing labeling. Boycott these buggers, who include Burt’s Bees (now owned by Chlorox), Naked Juice and Izze (Pepsico), Larabar, Cascadian Farm, and Muir Glen (General Mills), and RW Knudsen and Santa Cruz Organic (JM Smucker); or
- (On the right side) Help GMO labeling initiatives in various states, most recently Oregon, California, Washington, and Colorado. Buy from these good guys: Nature’s Path, Nutiva, Clif Bar, Lundberg, and more.
When you get to the Cornucopia site, click that poster a couple of times and it’ll enlarge for easy reading and forming your opinions of which companies deserve your dollars and which deserve your scorn and boycott. They’ll also help you print it if you’d like to carry it with you while shopping.
Whole Foods contributed to help labeling, but carries many of the offensive products from companies who are trying to keep you in ignorance, so caution is in order if you opt to shop there.
What’s your take on GMOs? Have you changed how you feed your animals or yourself since learning about them? Any tricks and tips to add? Tell us in the comments.
GE is a force to be reckoned with and it’ll take a lot of us to stop the greedmongers intent on running it full steam ahead down this dangerous path.
But, take heart:
“Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.”
