STUDY: What Does Science Say About GMOs – They’re Safe

By Community Manager • November 08, 2017

The following is an excerpt of a post at the Skeptical Raptor reviewing a large number of GMO safety studies. 

The science deniers of the world, whether they deny evolution, global warming, vaccines, or GMO safety, spend their time inventing pseudoscience to support their beliefs and claims. As I have written previously, “Pseudoscience is easy. It doesn’t take work. It’s the lazy man’s (or woman’s) “science.” But it has no value, and because it lacks high quality evidence in support of it, it should be dismissed, and it should not be a part of the conversation.”

Alternatively, real science is really hard. And it takes time. And it’s based on high quality evidence. And it is repeated. And it is almost always published in high quality journals. As I’ve said a thousand times, real science takes hard work and is intellectually challenging. You just don’t wake up one day and say “I’m a scientist.” No, it requires college, graduate school, teaching, working in world class laboratories, publishing, defending your ideas to your peers, and one day, if you don’t stop, you will be an authority in your little field of science.


Without really trying (though it took several days to read through the articles), I found 114 peer-reviewed articles, mostly published in moderate to high impact factor journals that support the safety of GMO crops over a wide range of hypotheses: from transgenic particles in bovine milk to how non targeted insects survive (or don’t). I found several meta reviews, which, as I’ve said before, are the highest quality sources of evidence. None of this research was sponsored by corporations, and frankly, I didn’t have enough time to read all those articles in addition to the ones included here. I even went to the effort to find the 2012 Impact Factors for each of the journals, so you know the quality of the journal. Note that impact factors, though I rely on them, are an imperfect measurement, much like a batting average for a baseball player doesn’t fully explain the skills that he may or may not have.

There were hundreds of other articles I could have included. But these are the ones I judged to be the best. And if you add up all of the conclusions written, a consensus forms. And that is that GMO’s are generally safe. There will be no transgenic DNA in your glass of milk. The transgenic DNA isn’t going to be absorbed through your intestine and cause some autoimmune reaction.

And I just didn’t find the articles that supported my “beliefs” or “opinions.” I found the best articles period. I found the articles that supported the broad scientific consensus that GMO foods are safe.

The term “GMO” typically refers to crops or animals that, through genetic engineering, have had a gene (or a few genes) from a different species inserted into their genome. This is by design to improve a crop or animal with genetic engineering. In fact, me and my colleagues recently published a paper on this very topic that addresses this very topic and gives more details on the plant selection practices used for GE crops.   However, you pick up on something very...

Nearly all foods today have been genetically modified or altered in some way over thousands of years through selective breeding. However, there are only 10 commercially available GMO crops in the U.S: soybeans, corn (field and sweet), canola, cotton, alfalfa, sugar beets, summer squash, papaya, potatoes and apples.   Below is a table outlining what year the nine crops became commercially available:   Squash 1995 Cotton 1996...

When people refer to Genetically Modified Organisms (GMOs), they are referring to precision plant breeding using genetic engineering. It allows plant breeders to take a desirable trait (like resistance to drought, insects, weeds, and disease) from one plant or organism and transfer it to the plant they want to improve, as well as make a change to an existing trait in a plant they are developing. You may have also heard of agricultural biotechnology or biotech seeds.... Read More
