GMOs The technology most people think of when they think of a GMO is called gene splicing. The technology consists of adding a piece of DNA or new genes to an organism. A GMO is an organism that has been altered through genetic engineering, which means the changing or relocating of living cells.

GMOs 2oo6 – Countries that grew 97% of GM crops were:
United States – 57% Argentina – 17% Brazil – 11% Canada – 6% India – 4% China – 3% Paraguay – 2% South Africa – 1%
7
GMOs: HISTORY 1975 – First recombinant DNA gene splice
1978 – Human insulin cloned 1980 – Chakabarty Supreme Court decision 1986 – Federal Coordinated Framework for regulating biotechnology 1993 – FDA approves rBGH 1994 – First biotech food approved, Flavr Savr tomato 1996 – First GM corn seed is sold; GM crops enter the food supply million farmers grew biotech crops in 29 countries

GMOs: Why? Increase yields by attacking the source of crop loss:
Insect resistance Herbicide resistance Virus resistance Drought resistance Salt tolerance No greater risk to human health than conventional food Ecological benefits

GMOs: Why Not? Increased Environmental Vulnerability

15
Activity
16
Scenario It’s The federal government just passed a law requiring all GMOs used for human and animal consumption to be labeled. The label must be visible to the consumer on the product package. The label must indicate whether or not your product contains GMOs, or was grown using GM plants. ( i.e. hamburger meat where the beef were fed GM feed)
17
Your Task In groups of 2, you will be assigned:
An organization or a company A product - made with/without GMOs Your company’s/organization’s opinion on GMOs (pro or con) As a group, create a label for your product based on the opinion your company/organization has on GMOs
18
Your Task Use colors, images, icons, etc. . . To market your product either for or against GMOs. The label must contain words that state whether or not your product contains GMOs. You have 3 minutes. Questions?
19
What did we learn from the activity?
How the label looks Consumer perceptions
20
What’s the big deal about labeling?
Why are people for/against GMO labeling? What are the potential economic impacts mandatory labeling would impose?
21
Current Labeling Policy
The FDA currently requires the labeling of GM foods: Altered nutritional property New allergens
22
Pro-labeling Arguments
The right to know Consumers can stay away from GM foods if they wish Trade policy Religious or ethical reasons – usually pertaining to potential transgenic animals Proposition 37
23
Proposition Required labeling sold to consumers made form plants or animals with genetic material changed in specific ways Cannot market it as “natural” Would have cost $1,000,000 to regulate Additional governmental costs to address violations Yes % No-51.41%
24
Anti-labeling Arguments
Labels imply adverse health effects Fulfilling the desires of some consumers would impose a cost on all consumers. Consumers who don’t want to eat GMOs already have the option of buying organic
25
FDA voluntary Label examples
Wording on Label FDA Comment GMO free (does not contain genetically modified organisms). OR Not genetically modified. Not recommended. “Free” implies zero content, which is nearly impossible to verify. “Genetically modified” is an inappropriate term, in that all crop varieties have been modified by plant breeders. We do not use ingredients produced using biotechnology. OK This oil is made from soybeans that were not genetically engineered. This cantaloupe was not genetically engineered May be misleading, because it implies that other cantaloupes may be genetically engineered. Currently, there are no such varieties on the market. Genetically engineered. This product contains cornmeal that was produced using biotechnology. This product contains high oleic acid soybean oil from soybeans developed using biotechnology to decrease the amount of saturated fat. guidelines. OK. The underlined part is mandatory because it indicates a nutritional change. The rest is voluntary under the proposed guidelines.
26
Issues with mandatory labeling
What specific foods would require labels? food products that were genetically engineered = they contain genes artificially inserted from another organism. What percentage of a GM ingredient must be present in a food before a label is required? 1%
27
Issues with mandatory labeling
Would meat, eggs and dairy products from livestock fed transgenic crops require a label? Some labeling proposals include these products How should regulators verify claims that a food is or is not genetically modified? Test strips PCR
28
What are the economic effects?
Producers must separate GMO from non-GMO products or choose to produce one or the other Cost of food increases Demand for GMO foods disappears Europe
29
The BIG Picture
30
Discussion for Tomorrow
Should genetically modified foods be labeled?
31
Future of GMO’s Bananas that produce vaccines against infectious diseases Fish that mature more quickly Cattle that are resistant to BSE Fruit and nut trees that yield years earlier Plants that produce new plastics with beneficial properties Milk with less lactose Nuts that do not cause allergies
32
Future of GMO’s Frost Tolerant sugar cane
Rice with Vitamin A-- to prevent blindness Oils with increased fatty acids Fruits with increased vitamin and mineral content Edible vaccines in tomatoes and potatoes Trees which can clean up heavy metal pollution from contaminated soil.
