Abstract: GM food can provide food safety guarantee for human development. It is safe to human health. Although the production and processing of GM food might have negative effects on biodiversity and soil ecology, and the use of pesticides and herbicides might pollute environment, its advantages are significant. These problems could be solved through improving GM technology to reduce the negative effects of GM food, enhancing the safety detection and perfecting the safety evaluation system of GM food.

Key words: GM food, safety, environment effects
