That should include food served by restaurants. The fact that the producers have been unwilling to label foods made from plants grown with recombinant DNA itself raises suspicion. But gene-spliced plants could introduce allergies, and so the specific genetic origins should be disclosed, both for health reasons and for moral reasons. The environmental problems from genetic manipulation across species is that the pollen will spread to wild plants and microbes and to farms which don't use genetically manipulated crops. There is also the possibility that beneficial insects and other animals may be harmed by eating the enhanced crops.
Human history is full of disasters caused by introducing harmful exotic organisms.
But policy should always be a comparative analysis of the real alternatives. It is not meaningful to compare recombinant crops with utopia. The world's population is still growing, and it needs to be fed. The expansion of the food supply will either come from turning more natural forests and grasslands into farms, or by increasing the yield of current farmland. Greatly enhanced yield can come from ever more pesticides and other chemicals, or by transgenic crops that can resist pests, drought, and frost, and offer better nutrition.
