Definition of Genetically Modified Foods

Genetically modified (GM) foods are foods that have been altered through
genetic engineering techniques. These techniques allow scientists to "cut
and paste" DNA from one organism to another in order to create a new
hybrid. For example, a certain gene can
be inserted into tomatoes in order to
maintain their freshness and colour. A different gene can be inserted into
corn and soybean plants to give them resistance to a certain herbicide. A
farmer can then control weeds in the corn and soybean crops by

ng with that herbicide.

A statement from Monsanto,

one of the world's leading biotechnology firms

"We all share the same planet
and the same needs. In agriculture, many of
our needs have an ally in biotechnology and the promising
advances it offers
for our future.

Healthier, more abundant food. Less expensive crops. Reduced reliance on
pesticides and fossil fuels. A cleaner environment. With these advances, we
prosper; without them, we cannot thrive.

“As we stand on the edge of a n
ew millennium, we dream of a tomorrow
without hunger. To achieve that dream, we must welcome the science that
promises hope. We know advances in biotechnology must be tested and
safe, but they should not be unduly delayed. Biotechnology is one of
s tools in our hands today."

Statements from Genetically Engineered Food:

A Self
Defence Guide for Consumers

GE foods are not being adequately safety
tested for possible damage to
our health . . .

Mounting scientific evidence
indicates that genetically engineered foods
and crops may present serious hazards for our health and environment . . .

The . . . British Medical Association . . . has called for a moratorium on all

genetically engineered foods because they may not be saf
e . . .

GMOs (genetically modified organisms) once created and released into the

environment, are permanent. They can never be recalled back into the

laboratory, nor can they be contained within a restricted pasture, farmland,

watershed, marine
environment, or geographical space.

Opinions About GM Foods

"The social benefits of genetic engineering are considerable: treating human

and animal diseases; increasing food production from crops and animals;


the nutritional value of foods; extending the shelf life of

food products. . . and helping to provide a cleaner environment. "


George G. Khatchatourians, Department of Applied Microbiology,
University of


"If left to me, I certainly would no
t eat it. We are putting new things into

food which would not have been eaten before. The effects on the

immune system are not easily predictable and I challenge anyone who

will say that the effects are predictable."


Dr. Arpad Pusztai, Research Scientist

“The risks of modem genetic engineering have been studied by

technical experts at the National Academy of Sciences and World Bank.

They concluded that we can predict the environmental effects by reviewing

past experiences with those plants and animals pro
duced through

selective breeding. None of these products of selective breeding have

harmed either the environment or biodiversity."


Jimmy Carter, Former U.S. President

"The fact that we do not really know what the long
term consequences

of genetic engine
ering will be, and are not prepared to move slowly and

take the time to find out, means that a grand experiment is taking place

and the outcome is anyone's guess. The Bt potato, Roundup Ready

canola, or Liberty
link soybean might be harmless, or they might


a disaster. We won't know until it is too late."
