Japanese consumers have exhibited no interest in--let us be honest, virulent hostility toward--genetically modified (GM) plants being grown for food. But it seems that allergen suppresant GM rice can be sold in Japan for human consumption. The trick is that growers have been working to make sure the GM rice is classified as a drug, not a food.
See that? That's how you work the system.
Now I wonder if American ranchers can get their beef reclassified as "a food supplement."
