Title: GM foods explained
1GM foods explained
- Presented by MADGE
- Mothers are Demystifying Genetic Engineering
2Who is MADGE?
- A network of mothers concerned about the
introduction of GM foods and crops
- We want to be confident about the safety of our
food - We believe we have the right to know what is in
our food
3Getting to know you
- Hands up if
- You are a mother
- You are a farmer
- You are a councillor
- You feel like you already know a lot about GM
- You feel like you dont know much about GM at all
4GM on our plates in our fields
- The Victorian government lifted the moratorium on
growing GM crops in 2008 - Farmers can now grow GM canola
- Whats the situation?
- Where are GM foods on our plates?
- Where are GM crops in our fields?
5GM Crops in Australia
Non GM canola
GM canola
- Can you tell the difference?
- Neither can we and thats the problem!
6The supermarket challenge
- Are any of these foods GM?
7Most GM foods arent labelled
- You may have heard that GM foods are labelled,
but - Most GM foods dont need to be labelled, because
of exemptions to labelling laws - Food from restaurants and food outlets
- Meat, dairy and eggs from animals fed GM
- Highly refined foods like sugars, starches
oils - Additives, processing aids flavours
- Accidental GM contamination up to 1 of
ingredients
8DNA, Genes Proteins
- DNA - the instructions for life
- Genes thought of as sections of DNA with
instructions for making particular proteins - Proteins are large organic compounds that perform
essential jobs and participate in every process
within cells.
9Genetic modification is not the same as
traditional selective breeding
- Traditional selective breeding involves the union
of 2 complete sets of whole chromosomes DNA and
all its binding proteins packed together - Idea of GM take a gene with a specific
characteristic from one species and insert it
into a host plant to give it that
characteristic - Like moving lego blocks around simple!
10Selecting and Inserting the genes
- Genes, or pieces of DNA code, may be from a wide
variety of life forms, or may be synthetic, or
both - They are chosen for a specific purpose or need
- There are two methods of inserting DNA
- The Agrobacterium Method
- The Gene Gun Method
- Lets demonstrate
11Is it really that simple?
- Last year, 300 scientists from 4-year research
project called ENCODE found that - The idea of one gene - one protein is wrong
- Genes can combine in different ways to make
different proteins - Every part of the DNA is used
- we remain too ignorant of how the genome works
to anticipate all the consequences, subtle or
obvious, immediate or long-term, of those
manipulations - Professor David Suzuki, 2007 (Geneticist, Author,
Environmentalist)
12Are GM foods safe to eat?
- We dont know because
- Our government regulatory authorities dont
independently test GM crops for health impacts
before approval - They make safety assessments by reviewing test
data submitted by biotechnology companies - There is no monitoring of the effects of GM food
on public health
13GM Crop Food Approvals - Australia
Food Standards Australia New Zealand (FSANZ)
Genetically Modified Foods Their Approval

14Hospital admission rates for anaphylaxis in
Australia have increased dramatically
- Hospital admission rates for anaphylaxis -
financial years 1993-94 to 2004-05 -
Rate per million population Paediatric food

MJA Vol. 186 No. 12 pp 618-621
15Anaphylaxis Admissions vs GM Crop Approvals
- Is there a link between allergy increases and the
introduction of GM foods?
16Is there evidence of possible harm from GM foods?
- There are only a small number of independent
safety studies of GM foods, but they have shown
adverse effects - Dr Judy Carman, nutritional biologist and
epidemiologist -
- Effects have been found on the liver, kidney,
pancreas, testes, digestive system, respiratory
system, immune function (including allergy) and
reproduction
17Many scientists are concerned
- Governments should never have allowed these
products into the food chain without insisting on
rigorous testing for effects on health - Editorial, The Lancet, 29 May 1999
- There have been no studies into whether any of
the millions of people who have been hospitalized
or died since GM crops were introduced got ill
due to eating these crops - Dr Judy Carman, Canberra Times, 28 July 2008
18World Scientists Statement
- Scientists are extremely concerned about the
hazards of GMOs to biodiversity, food safety,
human and animal health, and demand a moratorium
on environmental releases in accordance with the
precautionary principle. - The statement has been signed by 828 scientists
from 84 different countries, including - Dr. David Bellamy, Biologist and Broadcaster,
London, UK - Prof. Liebe Cavalieri, Mathematical Ecologist,
Univ. Minnesota, USA - Dr. Thomas S. Cox, Geneticist, US Dept. of
Agriculture (retired), India - Dr. Tewolde Egziabher, Spokesperson for African
Region, Ethiopia - Dr. David Ehrenfeld, Biologist/Ecologist, Rutgers
University, USA - Dr. David Suzuki, Geneticist, David Suzuki
Foundation, Univ. British Columbia, Canada - Dr. Vandana Shiva, Theoretical Physicist and
Ecologist, India
19Questions we are entitled to ask
- Why havent studies showing adverse health
effects of GM foods in animals been repeated? - Why dont our Government authorities carry out
independent animal feeding studies before
introducing GM crops into our food system? - Why arent all GM foods labelled to facilitate
traceability in the food system and monitoring of
public health effects?
20Crop and seed contamination
- Occurs through wind insect pollination
- Canola seeds are the size of 100s and 1000s -
contamination can occur during harvesting,
storage and transport - In Canada, 32 of 33 certified non-GM canola seed
stocks were contaminated - Agronomy Journal 95, 2003
- 216 cases of GM contamination have been recorded
in 57 countries worldwide
21Chaos on the ground
- Liability insurance - who pays?
- Only VIC NSW have lifted GM canola bans
- Non-GM farmers have concerns about the plan
for segregating GM from non-GM crops - Harvesters are concerned because it takes a week
to decontaminate a harvesting machine - Beekeepers need to certify what their bees have
fed on - How can farmers certify crops as non-GM if they
dont know where GM crops are growing?
22Who owns our food? Seeds patents
- Farmers gardeners have developed saved
swapped seeds for 1000s of years - Now domestic international laws grant patents
to corporations to own seeds - Farmers cant save patented seeds
- In the 1970s there were 1000s of seed
companies, now 10 companies own 57 of world
trade in seed
23Being a food detective
24First the good news
- We have lots of wonderful food in Australia that
isnt GM - Fruit vegetables
- Pasture-fed meats dairy
- Australian-grown cereal crops (except canola
from November) - Foods labelled Product of Australia
- But ingredients like additives enzymes may be
imported may be GM - Cottonseed could be GM canola from November
- Many producers have GM-free policies look
for the labels or call the information lines - Organic foods are GM-free
25What foods might be GM?
- Australian cottonseed oil, vegetable oil
(from November) canola oil - Find out what your chips are cooked in
- All other GM will be imported, mostly from the
Americas - The main international GM crops are soy, corn,
canola and cotton - Look out for soy lecithin/protein, corn/maize
syrup/starch think laterally! - A handful of soy lecithin is thrown into almost
everything processed - Food additives processing enzymes
26How can I avoid GM foods?
- Eat unprocessed foods
- make your own out of lovely Australian
ingredients - Except for cottonseed oil and soon canola
- Use the Greenpeace True Food Guide
- Look for products labelled GM-free
- Buy from local farmers markets
- Buy organic
- Ring information numbers on food packaging
- Be a food detective!
27If youre concerned, what else can you do?
- Be informed - sign up to the MADGE newsletter
- Go through your cupboards, and contact food
manufacturers to find out whether your foods
contain GM ingredients - Tell MADGE what you find out, so we can let
others know - Tell food manufacturers and retailers how you
feel about GM foods - Tell food manufacturers and retailers how you
feel about GM foods - Right now, Australian food companies are deciding
whether to use GM canola in their products - Tell your State and Federal politicians your
concerns - Sign the Greenpeace GM Food - Our Right to Know
petition
28GM Food - Our Right to Know
- At the very least it is imperative that any GM
produce be labelled - Stephanie Alexander
- People have a right to know what they are eating
- Margaret Fulton
- If we are to get GM canola, it should be
labelled, and if it is not labelled, we should
all ask why - Dr Rosemary Stanton, Nutritionist
29Its our food, we need to act
- Never doubt that a small group of thoughtful,
committed citizens can change the world - Margaret Mead
