Gene editing in farm animals: don’t bet the farm on this pig in a poke

“It is very worrying not only to read about yet another blunder by the industrial farming sector (Pigs in the pink: gene editing is set to revolutionise the farming industry, 17 March) but also that the article didn’t attempt to counterbalance with a different viewpoint. It is well known that healthy, agroecological, farming systems support healthy animals and plants that are then, by and large, resilient to disease. The solution for a sick animal is not to edit genes, because this does not address the cause of the problem and only makes it worse, as the ill health will only find a different way to express itself. In the meantime we are supporting unhealthy farming systems and their associated diseases, and consuming sick pigs.”

This is a fairly good article addressing a problem in the promise of gene editing.
