Genetically Engineered Foods
  • Kelli Brelsford

  • Jermaine Williams
  • Emily Taylor

2
What Do You Think?
  • 1. Do you think its is acceptable for scientists
    to genetically engineer food?
  • 2. Do you think that genetically engineered
    foods can be harmful for your health?
  • 3. Would you eat genetically engineered food?
  • 4. Do you think supermarkets should be able to
    label this kind of food?

3
What is genetically engineered food?
  • A genetically engineered crop is one that
    contains a gene or genes which have been
    artificially inserted instead of the plant
    acquiring them through pollination. The inserted
    gene is known as the transgene and may come from
    another unrelated plant, or from a completely
    different species a type of genetically modified
    corn, which produces its own insecticide,
    contains a gene from a bacterium. Plants
    containing transgenes are often called
    genetically modified or GM crops, although in
    reality all crops have been genetically modified
    from their original wild state by domestication,
    selection and controlled breeding over long
    periods of time.

4
The most common genetically engineered crops
soybeans
Potato
papaya
Yellow squash
radicchio
corn
Sugar beets
cotton
zucchini
Flaxseed
tomato
5
Substances contained within genetically
engineered foods
  • Genetically engineered foods often contain
    substances that have never been part of the human
    food supply.

How Is It Done?

7
Is it good for you?
  • There are about 40 varieties of genetically
    engineered food approved for marketing in the
    U.S.
  • 60-70 of food in grocery stores contain
    genetically engineered components

8
Health Hazards
  • There may be toxins present
  • People may have allergic reactions to substances
  • Genetic modification may decrease nutritional
    value
  • Genetic modification may promote the growth of
    antibiotic
  • resistant strains of bacteria
  • There has been no long term safety testing done

9
Environmental Hazards
  • Increased use of herbicides
  • Increased use of pesticides
  • The ecosystems may be damaged
  • Gene pollution cannot be cleaned up

Which foods are genetically engineered?
12
Why Kraft?
  • Largest food company in the country, second
    largest in the world
  • Products are found in 99 of U.S. households
  • Many products such as Taco Bell taco shells, Boca
    Burgers, Lunchables, Post cereals and Stovetop
    Stuffing have been found to contain untested and
    unlabeled genetically engineered ingredients that
    may put our families and environment at risk
  • Refused to label these inadequately tested foods

13
Valuable New Technology
  • Can develop more plentiful and nutritious food
  • More controlled method of natural breeding
  • No evidence to show that these foods have harmed
    anyone in anyway

14
Environmental Benefits
  • The use of genetic engineering in agriculture
    will increase crop productivity and therefore
    reduce the demand for agricultural land
  • Genetic modification can produce natural
    pesticides to substitute synthetic pesticides

15
Pros and Cons
  • Pros
  • No need for pesticides
  • Increased amounts of crops
  • Increase nutritional value
  • Cons
  • Strains of antibiotic resistant bacteria
  • Allergic reactions
  • Possibly toxic reactions
  • Decreased Nutritional Value

16
U.S. Policy
  • The agencies responsible for the jurisdiction
    of the regulation of genetically engineered foods
    are the FDA, the EPA, and the USDA

17
U.S. Policy
  • FDA
  • Enforce pesticide regulations set by the EPA
  • Authority to regulate all GE foods
  • Say that genetically engineered foods do not have
    to be labeled
  • EPA
  • Oversee pesticides both chemical and naturally
    produced
  • Determine maximum residue level of pesticides in
    or on foods
  • USDA
  • Oversees and issues permits for genetic
    engineering field tests

18
The Federal Food, Drug, and Cosmetic Act
  • As long as a genetically engineered product is
    not observed to be considerably different from
    the traditionally produced product than no
    labeling is required.
  • If any of the major ingredients of a product are
    produced by genetic engineering the name may be
    changed or labeling may be necessary.

19
Problems of Labeling
  • Some tests that would be needed to distinguish
    genetically modified foods from traditionally
    produced foods are unavailable
  • Mandatory labeling is a considerable cost and
    could possibly increase the cost of foods
