Gene Editing in Animals May Become Controversial

Your tall glass of milk may come from an unexpected source, thanks to DNA modification in animals. Also known as gene editing, this process uses enzymes to alter an animal’s DNA in specific advantageous ways. This may change an animal’s appearance or increase muscle mass. Such methods may be used to create better food products, to fight diseases, or even to design a household pet.

There are some major ethical concerns with all of this. Animal rights activists claim it is abusive to animals, while those concerned with food safety worry about the effects of modified DNA in the food chain. Finally, many fear that gene editing in animals will eventually lead to gene editing of human embryos.

These concerns are not far-fetched. The FDA has just approved the first genetically modified salmon for widespread consumption, soon to be available in American supermarkets. Stay tuned for a complex and perhaps divisive public debate.
