First, I must admit that I am not geneticist nor do I work for any type of lab etc. I play with networks and computers. These are my thoughts, opinions and interpretation of genetically altered food.
I have been interacting and consuming genetically altered items since birth. I have owned (bad word) and grown up with German shepherds and Chocolate Labs, both of which are totally different dogs, from their personality to physical size. Both dogs have been bred (genetically altered) from ancestral wolves some say. I know of a farmer in our area that has breed his Angus cattle to have shorter legs and larger bodies. This was done outside of a test tube, but is this still considered genetically altered food? With regards to the Cornish X, I don't know 100% if they are a test tube product or bred this way. As with the majority of chickens, they all are a long way from their jungle fowl heritage.
Let's move on to tomatoes . Everyone is talking about the heirloom tomatoes: back to the basics, a true tomato, etc. Originally tomatoes were knowns as Wolf Peaches. From what I have read they are related to deadly nightshade and mandrake. They are a native plant of the Andes. They grew in the wild to about the size of knuckle. n#1 This is a far cry from a Beef steak.

Here is another item mentioned Transgenic. From what I have just read, this type of genetic engineering has been going on since at least the 1930's in the USA. One of the major accomplishments
at that time was for wheat. n#2 A natural occurring process known as Horizontal gene transfer can occur between species. n#3 This is when genes of different species are transferred amongst each other.

I don't know if it is possible, but I would draw the line in eating genetically altered food if it is a cross between vegetables, fruit, insect , fish, mammals and or reptiles. I think evolution by mutation and selection is a naturally genetically altering process. I also don't believe in the use of steroids for animal enhancements. We as humans do benefit from the alteration of plants and animals. As I look out of the window at the neighbors orchards, I can see dwarfs, semi-dwarfs and standard size trees. These trees are also bred to reduce the need for pesticides by being insect and diseases resistant in some of the hybrid forms. In the future these pests and diseases will find a way to over come these defenses, I hope we are prepared. There will be a continuing growth in the human population that will have to be fed. I hope that the new and improved plants/animals are not rushed out into the market without research or testing.
In conclusion of this thread, I would like to say I have learned a lot.....something new and different.
