  2. Safety Issue Related To Genetically Modified Foods-Yi Yang

  5. Present Situation of GM foods 70% of processed foods on supermarket shelves–from soda to soup, crackers to condiments–contain genetically engineered ingredients

  6. The Benefits • Pest Resistance • Herbicide tolerance • Nutrition

  7. The Question That Really Matters • Are GM foods safe for human beings? • Do they have potential health risks in the long term?

  11. Pandora ‘s box

  13. Conclusion • Current methods for assessment have not been validated robust indicators of safety • Alternative strategies and advanced testing experiments to end this debate and people’s concern.
