Is DNA safe to eat? You may not have thought about it before, but you actually eat plant and animal DNA every day (assuming you’re not vegetarian, of course). In fact, there’s a whole industry set-up around testing the DNA of our food source.
Earlier this month, Therion International helped identify fake red snapper being served at sushi restaurants in Chicago. DNA tests showed they were actually selling tilapia and red sea bream instead. Another such company, IdentiGEN, has developed DNA TraceBack – a technique which checks on the path a piece of meat has taken from the ranch to your mouth. IdentiGEN calls DNA “nature’s bar code.” DNA tests are also performed on food to make sure that it is not genetically modified.
Other foods that have been verified using DNA tests:
Vareties of potato
Durum wheat for pasta
Composition of fruit pastes and pulps
Purity of olive oil
Varieties of tea and coffee
And here’s a myth about genes and food addressed by Biotechnology Australia:
Myth: GM food means that weâ€™d be eating genes and itâ€™s not natural to eat another organismâ€™s genes.
Itâ€™s impossible to eat without eating genes.
Every organism contains genes. When we eat an apple, we eat the genes in the DNA contained within its cells. These genes in the apple are â€˜foreignâ€™ genes, but they donâ€™t have any effect on us because they are digested. The same goes for eating meat.
