What Is Genetically Modified Crops? • Genetically Modified crops are crops that have been modified artificially through genetic engineering to enhance and introduce desirable traits.
Present Situation of GM foods • Soybean (93%) • Cotton (88%) • Maize (85%) • Sugar Beet (95)%
Present Situation of GM foods 70% of processed foods on supermarket shelves–from soda to soup, crackers to condiments–contain genetically engineered ingredients

We are just not SURE! What come out of the box?
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.
