GMO facts and myths – your one stop for scientific evidence

Genetically modified organisms (GMOs or GMs) are one of the most well-studied areas of biological and agricultural research. However, one of the tactics of the GMO refusers is that “there’s no proof that GMOs are safe.” It’s time to look at the GMO science facts – examining myth from science.

Typically, in a debate, the side making the assertion (those that say GMOs are unsafe) are responsible for the evidence that supports their contention. But, the anti-GMO gang relies upon the argument from ignorance, trying to force the argument to “if you can’t prove that they’re safe, they must be unsafe.”

The anti-GMO forces also like to invoke the precautionary principle, which attempts to shift the burden of proof to those who are advocating GMOs (or any new technology) until the advocates “prove” that there are absolutely no negative consequences of using GMOs.

The principle is often cited by anti-science and/or environmental activists when there is a perceived lack of evidence showing that this technology is absolutely safe.

I’ve written numerous articles about GMOs, focusing on scientific evidence supported by high-quality research. And more than a few articles debunked myths and bad research from the anti-GMO crowd. To assist those who are doing research on the topic, this article was created to be a one-stop shop for GMO science facts – and fiction.

Anti-GMO anti-vaccine activists – convergent evolution

anti-GMO anti-vaccine

I naively once thought that anti-GMO activists only occasionally crossed paths with the anti-vaccine ones. Sure, on the Venn diagram of anti-science beliefs, anti-GMO anti-vaccine activists overlapped quite a bit, but I just thought they were separate species. Maybe they once were, but there appears to be a substantial amount of convergent evolution between the separate species of anti-science activists. It’s hard to distinguish the two these days, as I regularly see one or the other type of activists just lump GMOs and vaccines together as one evil against all children.

GMO science – overwhelming consensus that it is safe

GMO science

Real science is hard. It takes lots of high quality evidence to support it. That evidence needs to be published in real journal. It needs to be repeated. And it has to be open to criticism and analysis. GMO science, the study of genetically modified organisms used for crops and food, shows us that GMOs are safe.

The hard work and intellectual challenges to form a scientific consensus about the safety of GMO crops and foods isn’t something that appeared out of the ether. These individuals didn’t suddenly wake up one day and proclaim from the ivory tower that GMO science says that GMOs are safe. Not even close.

Science has provided substantial evidence supporting the assertion that GMO’s are safe. GMO refusers have provided precious little evidence, save for Cherry PickingSpecial Pleading, and a few Strawman Arguments. Oh, and the occasional Poisoning the Well with the Monsanto shill accusations. Sometimes the GMO deniers will resort to the Naturalistic Fallacy that things that grow “naturally” ought to be the way foods should be – this ignores the fact that we’ve been genetically manipulating our food for ten thousand years. We’re just better at it today, but the DNA is still the DNA.

Like I said in another article, “The typical pseudoscientist will use logical fallacies to state very definitively that “it’s proven.” It’s the same whether it’s creationism (the belief that some magical being created the world some small number of years ago), alternative medicine (homeopathy, which is nothing but water, has magical properties to cure everything from cancer to male pattern baldness), or vaccine denialists. The worst problem is that in the world of the internet, if you Google these beliefs, the number of websites and hits that seem to state that they are THE TRUTH™ overwhelm those that are more skeptical or critical.”

So, using an open, but critical mind, the evidence is overwhelming – the GMO science says it’s safe for human consumption.

GMO dangers – another published paper retracted UPDATE

GMO dangers

The science of GMO dangers has been seriously overblown by activists that really have no science behind their beliefs. The safety of GMOs has really reached the point that almost all of the scientific evidence is firmly on the side of the safety of GMO crops and, by extension, foods. Beyond that, the scientific consensus of respected scientific organizations across the world have come to the conclusion that the body of evidence supports the safety of GMO foods. And that GMO crops, which have been around for 10,000 years, are necessary to feed the people of this planet.

Nevertheless, the activists who continue to push the GMO dangers trope continue with their bad science. A few years ago, an article by Gilles-Eric Séralini was published which trumpeted the belief that GMOs cause cancerThat article was widely ridiculed and criticized by scientists across the world. Eventually, because of bad study design, terrible statistics, and harsh criticism of the conclusions, the journal that published the article retracted it.

It’s clear, at least to me, that when a side of a sociopolitical debate lacks scientific evidence, such as the anti-GMO side, they grab at anything, including Séralini’s retracted study, in an attempt to cherry-pick themselves into scientific legitimacy.  And it’s happened again.

Dr. Oz and Donald Trump – two anti-science salesmen promote each other

Dr. Oz and Donald Trump

For those of you returning from an outing to the Andromeda Galaxy, Donald Trump is the Republican candidate for President of the USA. And Dr. Oz is the medical quack who pushes pseudoscience and junk medicine. Yesterday, Dr. Oz and Donald Trump met on Oz’s TV show to talk about Trump’s health record. If you think this showed us anything useful, I’ve got some weed that will cure every cancer.

I was not surprised when, earlier this week, someone announced that Trump would discuss his health with Dr. Oz. My first thoughts were, “of course he would.” If I wanted anyone to do the least critical questioning of Trump, I’d choose Matt Lauer to ask Trump about international affairs, and Dr. Oz to ask him about medical issues.

On many levels, these two conmen are a perfect match. Trump hates real science like vaccines, or climate change. And Dr. Oz loves pseudoscience. Two peas in the same pod.

Since this feathery dinosaur loves politics and trashing junk science, it feels as though it can’t resist the opportunity for some fun. Who wouldn’t?

Dr. Oz falls for the overhyped and debunked GMO corn study

dr. oz

A few weeks ago, Gilles-Eric Séralini and his homeopathy loving coauthor published an article in Food and Chemical Toxicology that concluded that glyphosate (known as Roundup)-resistant NK603 GMO corn, developed by Monsanto, causes severe diseases such as tumors in rats. And usual anti-science websites bought into this nonsense, including the TV medical practitioner, Dr. Oz.

It’s time to remind everyone that the Séralini study was bogus, and that Dr. Oz is also bogus. Here we go.

Anti-GMO articles retracted – shocking news

Anti-GMO articles retracted

I’ve written this about 1 million times online (give or take 990,000) – the only thing that matters in science is evidence. Not opinion, not anecdotes, not bad research. The science that supports the safety and productivity of GMO crops is overwhelming, while one more of the anti-GMO articles has been retracted.

Science wins. And I guess lies and manufactured data don’t.

If this sounds familiar, it is. I wrote about a few weeks ago, discussing  a paper, by Federico Infascelli and other colleagues, an animal nutrition researcher at the University of Naples in Italy, who attempted to show that GMO soybeans consumed by female goats could pass modified genes into the blood and organs of baby goats.

According to an article in Retraction Watch, there was a lot more going on. The good people at Retraction Watch translated an article in the Italian newspaper La Repubblica, which claimed that “an investigation suggests that Infascelli has manipulated images to suggest GMOs are harmful. He could face fines and be suspended from the university.”

Retraction Watch also  that La Repubblica “also reported that a committee appointed by the rector of the university, Gaetano Manfredi, found errors in Infascelli’s data that suggested he had manipulated the results to show GMOs were harmful.”

And Infascelli’s research improprieties continue to grow.

Séralini GMO article vindicated by courts – absolutely not

Séralini GMO article

The infamous Gilles-Eric Séralini GMO article – which made baseless claims about GMO corn causing cancer, and which was subsequently retracted – is back in the news. The anti-science crowd is trumpeting a decision by a French court that decided that Séralini was libeled by Professor Marc Fellous, former chairman of the French Biomolecular Engineering Commission, for “forgery” and “the use of forgery.”

So let’s look at this carefully. Continue reading “Séralini GMO article vindicated by courts – absolutely not”

Séralini’s controversial GMOs cause cancer article retracted

GMOs cause cancer

In 2012, the interwebs exploded because of an article (pdf) published in Food and Chemical Toxicology by Gilles-Eric Séralini et al. that attempted to show that GMOs cause cancer in rats fed genetically modified corn which is resistant to the herbicide Roundup. They also found similar health problems in rats fed the herbicide alone (along with non-GM feed). The rodents experienced hormone imbalances, along with more and larger mammary tumors, earlier in life, than rats fed a non-GM diet. The authors claimed that the GM- or pesticide-fed rats also died earlier.

Séralini et al. stated that this is the first time GMO corn has been tested for toxicity throughout a rat’s lifespan even though this type of GM corn accounts for more than half of the US crop.

Séralini’s article could have been an important part of the discourse regarding the safety of GMOs – except for a few important problems. Scientists across the world criticized the study for its bad study design, bad statistics, and overhyping of the results.

I personally found the study lacking in basic toxicology methodology, like providing us with dose-response studies, that show us at what level of consumption of the GMO corn would have an effect (if there is one). Of course, Séralini used so few rats in his “study” that it would have been difficult if not possible to develop a dose response.

GMO opponents – left’s version of global warming deniers

Scientific denialism (also known as pseudoskepticism) is the culture of denying an established scientific theory, law or fact despite overwhelming evidence, and usually for motives of convenience. Sometimes those motives are to create political gain for their supporters.

Two of the most annoying denier viewpoints are the darlings of the right wing: evolution denialism and global warming denialism. The former is more commonly known as creationism and is mostly an American phenomenon, though it is known in other countries. In the USA, creationism is a fundamental part of the Republican Party strategy across the country. In fact, much of the anti-evolution legislation pushed by Republican legislatures in the United States has an anti-global warming component.

Although denial of anthropogenic global warming and evolution tend to be the domain of the right wing, the left-wing have their own particular brand of science denialism–GMOs (though some think I should include vaccine denialism too).  Global warming deniers and GMO opponents share some of the same tactics and beliefs, even if they are the opposite ends of the political spectrum.
