It is time for another entry in the mailbag series where I answer feedback email from readers and others. If you want to send me a question, comment or any other kind of feedback, please do so using the contact info on the about page.
Science is hard. That is why we need dedicated research to explore, discover and untangle the nature of reality and how the world works. When a scientific issue also becomes socially controversial with powerful forces trying to persuade us to hold positions that run counter to evidence and mainstream science, it can get very complicated. One such area is genetically modified crops and genetically modified foods. It is an area where many different issues, from details of molecular biology and field trials to patent law and corporations get mixed together in a confusing mess. Read more of this post
One of the best strategies used by scientific skeptics against anti-GMO activists on the Internet is to ask them to cite one risk that exists with genetically modified crops, but does not occur with any conventional breeding method. This is best done after presenting evidence of the safety and efficacy of GM crops and other GM applications. That way, the anti-GMO activist has to both respond to the published evidence, but also figure out unique risks with GM crops. Because it is very hard to find these supposed unique risks, the anti-GMO activists finds themselves in a very difficult position.
Far from being stumped, anti-GMO activists often try to come up with alleged unique risks, but they are often mistaken: the same risks occur with traditional breeding methods such as cross-breeding, marker-assisted breeding, radiation breeding or breeding that uses mutagenic substances such as EMS. This post repels many of the most common retorts given by anti-GMO activists when asked to cite a unique risk with genetic modification compared with conventional breeding methods.
What about allergens?
GM crops are required to go through stringent toxicological and ecological testing by regulatory authorities. This includes testing for the presence of allergens. If GM crops are found to contain allergens, they are not approved. In contrast, there is nothing that prevents a farmer from developing a new form of food item that we know contain allergens, such as peanuts, or crossing plants that cause the mixing of thousands of genes that could potentially cause an allergen.
