What are genetically modified organisms (GMO, GMF, Frankenfoods)?http://www.csa.com/discoveryguides/gmfood/overview.php • Also known as transgenic • Crop plants created for human or animal consumption using the latest molecular biology techniques. • Create plants with the exact desired trait very rapidly and with great accuracy.
Advantages of GMOs • Pest resistance • Herbicide tolerance • Disease resistance • Cold tolerance • Drought/Salinity tolerance • Nutrition • Pharmaceuticals • Phytoremediation (clean up heavy metals in soils – gm poplar trees)
What are some of the criticisms of GMO foods? • Environmental Hazards • Unintended harm to other organisms – Monarch butterflies and milkweed/corn pollen • Reduced effectiveness of pesticides • Gene transfer to non-target species • Human Health Risks • Allergies • Unknown/Unintended health effects • Economic Concerns • Expense and time bring GMO plants to market • Patents and control by agrichemical companies
How are GMO/GMF/Transgenic Foods Labeled? • Agribusiness firms believe labeling should be voluntary – They say, “Let the markets decide!” • Consumer groups say labeling should be mandatory – They say, “I want to know what I am eating!” • FDA’s current position grounded in the Food, Drug and Cosmetics Act… • GRAS • Generally Recognized As Safe • What do you think about this?
