Due to GM rice species belongs to a man-made species and are provided with toxicity, which can kill insects and their other property are a few of understanding. Risks also come from the potential genetic pollution, so they may pollute the species and animals, that their effect on human beings is not redemptive.
Edible safety test of GM rice will maybe refer to edible safety test of crops produced by artificial soil from programs №1 and №20 written by me in 2003, as following .
First period：I eat the grain, vegetables ,fruits and other products produced by artificial soil for 1 year, after it will be proved harmless then next.
Second period：some animals such as rabbit, sheep, chicken eat them a half year, after they will be proved harmless then next.
Third period：volunteers eat those products a half year, after they will be proved harmless then next.
Finally, through the test examination, the products? produced by artificial soil can be feed to people.
