"AFAIK, there is almost no risk in transferring genes from one edible non-toxic product to another edible non-toxic product. " And where is your knowledge coming from? I am certainly not a biologist, but as far as I know, there are quite some plants that are edible in the breed we eat - but a different wild form is toxic (carrots for example). How are you sure, the wrong (dormant) genes do not get transfered and activated, without testing? Or even with the same plant, potatoes. The root is good for us, but the flower is toxic. In other words, you always have to do extensive testing, when you play around with genes. Genes are not computer modules you just swap around and turn on and off. It is way more complicated.
