  1. The Plant World and Genetic Engineering Part III Public Issues Jana Klose, Greg Lampard UBC Biotechnology Laboratory

  2. Whoa! Who is Keeping us Safe? • Canada • Health Canada • Human Safety • Stringent evaluation of safety of GM foods • How was the product made? • Is the GM product different from the non-modified product (Composition and Nutritional value)? • Is there potential for toxicity of allergic reactions?

  3. Safety • Canadian Food Inspection Agency (CFIA) • Regulation of the non-human effects • Stringent Safety testing • Environmental impact – field trials • Impact on Livestock – feeding trials • Registration of all crop products under the Seeds Act

  4. Food Safety • GM products must meet ALL standards • Additional testing can be requested at any time – before or after approval

  5. What about allergic reactions? • All new food products (GM and non-GM) must undergo strict testing • Testing includes: • Potential for an allergic response • Comparison of the food versus all known allergens

  6. What about allergic reactions? • Many people have food allergies • The brazil nut example: • A transgenic soybean with an inserted gene from Brazil nuts was created • It was later found that this gene encoded a major allergen • As a result of this assessment, commercial interest in this transgenic soybean variety was abandoned • Steve L. Taylor Department of Food Science & Technology, University of Nebraska, Lincoln, NE 68583-0919, USAhttp://www.agbios.com/articles/2000151-A.htm

  7. Labeled can of tomatoes in Britain Source: Nature, April 22, 1999 Are GM Foods Labeled? • Policy is controlled by Health Canada and the CFIA • Currently approximately 70% of foodstuffs in North America contain components derived from GM crops • Voluntary labelling

  8. Public Acceptance • What is it? • What do I get out of it? • Is it safe? • Do I have choice? • Is it natural?

  9. Public Acceptance • What is it? • Producers and consumers must come together to educate each other on what the technology is and also what consumers want • Producers have not done a good job • Consumers must decide!

  10. Public Acceptance • What do I get? • Much of the current products directly benefit farmers • What would the reaction be if a non-allergenic peanut or edible vaccine was produced? • Perhaps resources should be devoted to “useful” products

  11. Public Acceptance • Is it safe? • Safety testing is stringent, but short term only • Results made public? • Labeling • Do I have a choice? • Labeling products would give consumers the choice to use or not to use

  12. Public Acceptance • Is it natural? • Genetic modification of plants is a natural process – Recall the Agrobacterium example from lecture 1

  13. Summary • Transgenic plants have potential to impact many areas, including our food supply and our healthcare system • There is no doubt that the technology works • It is essential that proper testing of all products be carried out prior to commercialization

  14. Summary • Labeling products would allow consumers to choose what they want to consume • Educate yourself!
