  1. Future Food of Frankenfood? Issues with Genetically Modified Foods

  2. Poll • Have you ever eaten a genetically modified food? • 60% said no • Given the option, would you eat a genetically modified food? • 54% said no • 38% said yes

  3. More than67% of processed foods contain genetically modified ingredients

  4. Which Crops are Genetically Modified? http://sustainabletable.org/wp-content/uploads/2007/11/corn1.jpg 2/11/11 http://www.ncagr.gov/stats/general/Images/Cotton.jpg 2/11/11 86% Corn 93% Cotton http://www.aphis.usda.gov/biotechnology/images/sugarbeet6.jpg 2/11/11 http://agriculture.sc.gov/UserFiles/Image/soybeans7.jpg 2/11/11 93% Soy 95% Sugar Beet

  5. What Does Genetically Modified Mean? Genetically Modified (GM) food: A food whose genes have been specifically and deliberatively altered using genetic engineering methods.

  6. Before GM Foods Iceberg Blackberry (chemical) Rio Red Grapefruit (radiation) http://www.bulbnrose.org/Heredity/Burbank/WhiteBlackberry/berry4.jpg 2/16/11 http://legacycitrus.com/Data/Products/1/imgccitrusleft.jpg 2/16/11 Selective Breeding Chemical Treatment Radiation Treatment

  7. How Are GM Foods Created? http://www.ag.ndsu.edu/pubs/plantsci/crops/a1219-2.gif 2/27/11

  8. How Are GM Foods Created? • “Transgenic” • Alternatively, genes can be altered without introducing foreign genetic material

  9. Potential Benefits Plants: Produce specific vitamins or proteins “Golden Rice” Beta-carotene → Vitamin A http://www.agricorner.com/wp-content/uploads/2010/10/rice-plant.jpg 2/17/11 http://goldenrice.org/image/silver+gold.jpg 2/17/11

  10. Potential Benefits http://www.monsanto.com/products/Pages/grain-sorghum.aspx 2/18/11 Higher yield Drought tolerance/less water use

  11. Potential Benefits http://cropandsoil.oregonstate.edu/sites/default/files/news/canola.jpg 2/18/11 http://mulch.cropsoil.uga.edu/brummer/pix/Expo%20alfalfa.JPG 2/18/11 • Herbicide tolerance • “Roundup Ready” • 85%

  12. Potential Benefits http://cropandsoil.oregonstate.edu/sites/default/files/news/Holland_Potato.jpg 2/18/11 • Insect resistance • Bacillus thuriengensis (Bt) • 25%

  13. Potential Benefits Animals: • Produce less waste • “Enviropigs” • Produce less pollution • Cows that don’t produce methane

  14. Potential Benefits http://a57.foxnews.com/static/managed/img/Scitech/604/341/AquAdvantage%20Salmon%202.jpg 2/23/11 Grow faster “AquAdvantage” Salmon

  15. Problems Safety Toxins Allergens Long term? Environmental Cross-pollination Dominance over wild animals

  16. Pollination http://www.pacificseed.com/images/seeds.gif 2/28/11 Replanting Seeds Organic Farms Herbicide Resistance http://www.ksda.gov/includes/images/plant_protection/Noxious%20Weeds/CanadaThistlePlant50.jpg 2/28/11

  17. Sugar Beets http://www.dnadropbox.com/wp-content/uploads/2011/02/ Genetically-Modified-Sugar-Beets.png 2/28/11 “Roundup Ready” Approved in 2007 Many seeds grown in Oregon

  18. Sugar Beets • Worries about pollinating other crops • Chard • Table Beets

  19. AquAdvantage Salmon • Aquabounty • Grows faster—full size in ½ the time • Two foreign genes: • Growth hormone related genes from Chinook Salmon • Anti-freeze protein (AFP) gene from ocean pout • Potentially the first commercially grown GM animal

  20. AquAdvantage Salmon http://sallyhanreck.com/wp-content/uploads/2010/09/article-1309316-0B0E5BFF000005DC-49_468x2691.jpg 3/1/11 • Potential to devastate wild populations • Reproductively sterile • Only females will be sold • Only grown in inland, contained facilities

  21. EQ How should genetically modified foods be regulated?

  22. Duke University Nutritional value Toxins/allergens Disease susceptibility Pollution from waste Resources required to feed it Consequences of escaped GM animals Economic impact Potential to cross-pollinate

  23. Laws/Regulations Should GM food developers have rights over plants accidentally pollinated by GM crops? Should GM foods not be considered organic?

  24. Service Learning

  25. My Solution A better protocol to approve or disapprove GM foods Revise ownership laws Reconsider what “organic” is
