AExpert Answer

No commercially available crops contain allergens that have been created by genetically engineering a seed/plant. And the rigorous testing process ensures that will never happen.


There are thousands of proteins in the diet, and only a small fraction of them cause allergies. With respect to GMOs, the U.S. Food and Drug Administration has specifically focused on allergy issues and requires companies to analyze the proteins they are using in the biotech process to determine if the proteins are allergenic. This entire process is well regulated and monitored and takes years to complete. The only documented case where an actual allergen was introduced into a plant by genetic engineering occurred during an experiment trying to improve the nutritional quality of the soybean by using a Brazil nut protein. The Brazil nut protein was in fact identified as an allergen in the new soybean, which prompted the researchers to halt the experiment, and this new soybean never entered the market.

While there might be some institutions with the capability to make these transgenic watermelon and coconut plants for you, that does not mean that you would be able to actually plant them out. First, the institution would need to have a Biological Use Authorization to work with recombinant DNA to make the vectors to transfer the genes. Then they would need to be able to do the tissue culture required to transfer the genes and regenerate whole plants again, which can sometimes be difficult.... Read More

Yes, the EU is one of the geographies where GM-derived food and animal feed must be labeled according to conditions outlined by the European Commission on this webpage. GM labels are very common on sacks of animal feed. Depending on the type of animal, GM labeled feed is often the standard – except of course when it comes to GM free or organic supply chains.

The short answer is no, neither MSG or animal extraction are from GMOs, nor is MSG, animal extraction, or animal products/animal DNA in GMOs.   When people refer to Genetically Modified Organisms (GMOs), they are referring to precision plant breeding using genetic engineering (also called GE). 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...
