QIf a cow eats GMO corn or soy is there any way to tell or is there any difference in that animal's meat or milk as opposed to an animal that consumed only organic feed?

If a cow eats GMO corn or soy is there any way to tell or is there any difference in that animal's meat or milk as opposed to an animal that consumed only organic feed?

AExpert Answer

No! There is no way to detect whether an animal has been fed GM feed because there is no content from any part of the GM feed in the flesh, milk or eggs.  The GM feed is digested and assimilated in exactly the same way as any other feed.  There is in fact no meaningful measurable difference between GM and convention feeds.

 

Actually that's not exactly true.  It turns out that conventional and organic feeds can have more of the mycotoxin fumonisin in them than does insect resistant GM feed.  Specifically, studies show that insect protected corn can have less fumonisin.  Molds that produce mycotoxin often grow at sites of insect damage on corn ears and because the GM grain has less insect damage it has less mold and consequently lower levels of fumonisin.  Thus GM grain can in this instance be safer than non-GM.  Fumonisin causes esophageal cancer, neural tube defect babies (NTDs) and other illness so this is an important benefit that is largely being over-looked because of the hysteria that has been created around the safety of GM crops.

Thank you for your question. There are various aspects of your question. I assume your question refers to the use of Agrobacterium rhizogenes by scientists to intentionally transfer genes from the bacterium to plants. Infection and DNA transfer from this bacterium occurs in nature all the time to cause disease. Such transformed plants are not classified as GMOs since transfer occurred naturally. If this is done by scientists then it would be classified as a GMO. Rules and...

I’m a Monsanto scientist who has more than 20 years of experience with genetic modification of plants. I will try to answer your question, even though I don’t ever do experiments on animals, certainly not on humans, of course! Can humans be genetically modified…but a much bigger question is should humans be genetically modified? There are two ways to think about genetic modification of humans (or any animal). One way is modification of somatic cells, and the other is the... Read More

The simple answer is that 20+ years of composition assessments of GMO crops have demonstrated that crop composition is not appreciably affected by the GM process (1). In addition, data collected through that time have indicated that general factors such as the growth environment can contribute to notable variation in component levels (2). Plant agglutinins (or lectins) and amylase inhibitors are examples of anti-nutritional compounds that may be present in crops. The relevance of such a... Read More
