GM Government caught out
Having promised that it would not allow any moves towards the commercial
sale of genetically modified (GM) crops whilst its farm-scale GM crop
trials were proceeding, the UK Government has been accused by environmental
campaigners of trying to get GM crops onto the market through the back
door. Luckily, Government plans to allow the seed of a new variety of
GM maize, Aventis Chardon LL, onto its list of approved seeds were
spotted by Friends of the Earth and are now being challenged using a little
known and little used National Seed List regulation. The hearing considered
presentations from 68 large environmental organisations and concerned
individuals, who have each had to pay £90 to have their objections
heard.

2.10.00
Two of the senior scientists on the hearing panel have heavily criticised
the Governments and Aventis attempt to get Aventis GM
maize Chardon LL licensed as a cattle feed in the UK. Professor Bob Orskov,
the director of the International Feed Resource Unit at Aberdeen (Scotland),
dismissed Aventis research data on safety as inadequate for three
main reasons: it had not even tested Chardon LL on cattle, only on rats
for two weeks and broiler chickens for six weeks; both rats and chickens
only have one stomach whilst cows have four; the tests on the chickens
did not even include tests for toxicity. He stated that he would not drink
the milk from cows fed on GM maize given our current level of knowledge.
He also pointed out that there was no obvious demand from farmers for
GM cattlefeed, only from Aventis.
Dr. Vyvyan Howard dismissed Aventis claims that some of the usual
safety tests were unnecessary and that GM crops are not materially different
from natural crops (now widely discredited). In the case of Chardon LL
he found significant differences in the composition of fat, protein and
fibre, as well as in fat and carbohydrate levels.
Even the UK Ministry of Agriculture, Fisheries & Food admitted that
the safety tests carried out to date may not meet minimum legal requirements.
Ed.- The hearing has now been suspended indefinitely following the discovery
that official safety tests by the French authorities had only been carried
out for one year rather than the two years required under EU regulations.
The defects in the French testing system have serious EU-wide implications.
Beyond human competence?
The US Environmental Protection Agency has stated that it is unlikely
to ever again grant a GM crop a partial license (i.e. for
animalfeed but not human food). Its reason is functional rather than scientific
or philosophical: you just cant trust people where theres
a profit to be made. The manufacturer, Aventis, agreed to label every
bag of its Starlink GM corn seed to explain the restricted use but failed
to do so, and the corn ended up in human food. Whether the EPA decision
was due to distrust of motive or management competence, it is good news
for the consumer. Scientists are very concerned that humans might pick
up alien genes by eating animals fed GM animalfeed.

Milking the science
A New Zealand government research agency is planning to add human genes
into dairy cattle with the aim of making their milk more like human milk
and more palatable to consumers. Opponents are appalled that
this has been suggested before any debate on the ethics or health implications
of the issue has been undertaken, especially since New Zealand has no
food labelling laws to give consumers choice.

GMd policing
The UK Governments Food Analysis Performance Assessment Scheme (FAPAS
) tested 80 laboratories across Europe used by retailers to check for
GM contamination and found widespread failure and inconsistency. 20% of
the laboratories missed GM ingredients. 60% found them where there werent
any. One laboratory found 12 times higher levels of GM ingredients in
one product than another laboratory.
These findings mean that many products on the shelves labelled as GM-free
probably are not, and vice versa, but the UKs new Food Standards
Agency was surprisingly relaxed about it. We feel the current tests
are effective when correctly applied. Detection is only one method of
enforcement; there are documentation checks and sourcing.

Super-gonorrhoea
Super-gonorrhoea
Early in 2000 the European Union rejected an application from Monsanto
to sell GM cotton in Europe. It is possible that their rejection was due
to strongly worded advice that GM cotton could lead to widespread human
resistance to the main antibiotic used to treat gonorrhoea. This advice
was received by the UK Ministry of Agriculture, Fisheries & Food in
February 1999 but only made public a year later.
The concern is that the aad gene which confers resistance
against both streptomycin (a second line antibiotic used for tuberculosis)
and spectinomycin (the drug of choice for treating gonorrhoea already
resistant to penicillin and third generation cephalosporins) is contained
in both Bollgard (insect-protected) and Roundup Ready (herbicide-tolerant)
GM cotton. The Neisseria gonorrhoea bacterium could acquire the aad
gene from GM cotton seed oil (used in processed foods) during infection
of the mouth, the small or large intestine, or the respiratory tract.
It could also acquire the aad gene indirectly from other bacteria
in the internal and external environments of animals and human beings,
who themselves picked it up from GM cotton plant materials. Every part
of the cotton plant is used. The 60% which is cotton seed is used to extract
cotton seed oil for human foods, and cotton seed cake for animalfeed.
The GM cotton itself is used, of course, to make cotton, but the applications
where it could pass resistance to gonorrhoea bacteria include sanitary
towels, tampons, nappies, bandages and other wound dressings. Dr. Mae-Wan
Ho, a geneticist and biophysicist from the UKs Institute of Science
in Society, condemns the UK Government for effectively suppressing this
information for twelve months because it could have helped prevent the
planting of millions of hectares of GM cotton world wide. She calls for
the destruction of all GM cotton crops to protect our fast diminishing
armoury of antibiotics.

Terminator 2?
Scientists working for Swiss biotech giant Novartis have patented new
technology which can switch plants immune systems on and off using
a chemical spray. Novartis claim their only interest is to give farmers
greater control but cynics point out that it could equally well be used
to force farmers to buy the companys chemicals each year in order
to have a healthy crop. Environmentalists are very concerned that the
contamination of the environment through cross-fertilisation would be
even more disastrous with this technology than with basic GM technology.
Novartis believes the technology could be applied to every crop on Earth
and already has plans to develop immune-manipulable barley, cucumber,
tobacco, rice, chilli, wheat, banana and tomato.
Ed.- Ironically, given this nightmare scenario, Novartis also manufactures
the sweet dreams comfort drink Ovaltine!

GM
virus field tests
At least the UK public are aware that, for its
own (difficult to understand) reasons, the UK Government is determined
to conduct field trials of GM crops in the UK. What most do not realise
is that, this year, there is also a field trial of a GM pesticide - actually
a GM virus. This virus is a baculovirus, a virus specific to arthropods
(insects, spiders and crustaceans) which has probably been genetically
modified with a scorpion gene. Even less is known about GM viruses than
about GM plants - in particular about their ability to damage the environment
or human/animal health. What is known is that their reproduction is unpredictable
and prone to creating undesirable variants, and that they are very persistent.
Baculoviruses have been used in gene therapy for humans. They can infect
the liver and may have implications for auto-immune diseases.
ACTION - Write to the Department of the Environment,
Transport and the Regions (DETR) deploring the introduction of field trials
of GM viruses without any public discussion. The address is: DETR, Eland

Naked DNA
So-called `naked DNA' (DNA stripped of its protein
in a laboratory or by exposure to natural detergents or phenols in the
environment for use in genetic engineering) poses serious threats to human
health. It can be taken up by cells and infect people or animals that
are not part of the normal host range of the virus. Anyone exposed to
GM crops is in danger, and particularly if exposed to plants genetically
modified with a human gene.
Exposure can be through eating the plant, breathing
in its pollen, or touching cut, wounded or decaying plant parts. The impact
of GM proteins and genes in the contamination of surface and groundwater
have been dangerously underestimated. Much further study is needed pending
which field trials should be curtailed.

GM'd honey ...
Friends of the Earth has identified two examples

... and bees
The German scientist Hans-Hinrich Kaatz has confirmed
that his latest study has found that a gene used in GM oilseed rape had
jumped species and infected bacteria in the guts of bees which fed off
its pollen. He believes that any danger to the bees' health can be ruled
out but accepts that there may be implications for human health. He advises
people not to panic until the results of current research on the bees'
human equivalents are known.
The DNA of bacteria and yeast taken from bees'
guts contained the same modified genes as those added to the plants whose
pollen the bees had fed on. This shows that modified genes can jump species,
the `Pandora's Box' feared by anti-GM campaigners. When the bacteria and
yeast were exposed to the herbicide glufosinate they survived, just as
the GM plants on which they fed had been genetically engineered to do.
Further work is needed to confirm these findings.

Superweeds
Cross-pollination between GM canola and wild weeds
has produced super-weeds resistant to three major herbicides: Roundup,
Liberty and Pursuit. The superweeds were found on a Canadian farm near
Sexsmith, Alberta. If the superweeds spread, farmers will have to use
stronger and stronger herbicides, further dispelling the myth that GM
crops are more environmentally friendly.

GM crops designed to be better able to survive
higher doses of pesticides will probably lead to growing resistance to
that pesticide in weeds growing amongst or near the crops. The higher
levels of pesticides used will, of course, pose a direct threat to the
environment. A good example is maize genetically engineered to be resistant
to the pesticide glufosinate-ammonium. This toxic pesticide is rightly
strictly controlled. In particular, its use is not allowed from the end
of September until the beginning of March to reduce the risk of poisoned
run-off water contaminating streams and rivers. Apparently, the GM crop
trial sites have been granted an unofficial exemption from these regulations
and permits to use glufosinate-ammonium were granted for October and November
1999.

US cover up
US lawyer Steven Druker was given access to 40,000 pages of US Food &
Drug Administration (FDA) files under public disclosure legislation and
discovered that the FDA had suppressed fears from its own scientists that
GM plants could produce unexpected new toxic substances. It ignored the
views of 11 out of 17 FDA scientists (requiring mandatory testing and
a freeze on sales until rigorous tests had been done) when it drew up
lax rules on GM food safety, facilitating the US boom in GM crops in the
early 90s.
Ed.- The lawsuit launched against the FDA by a coalition of scientists
and religious leaders has uncovered numerous internal documents from the
FDA, in which its scientists express concerns about the safety of GM crops
and the advisability of classifying GM foods as substantially equivalent
to conventional foods. Stephen Druker J.D. says in a paper that: No
genetically engineered food has yet satisfied the criteria mandated by
US law.
Examples of internal FDA statements uncovered by the lawsuit include:
The processes of genetic engineering and traditional breeding are
different, and according to the technical experts in the agency, they
lead to different risks. (Dr. Linda Kahl), and There is a
profound difference between the types of unexpected effects from traditional
breeding and genetic engineering ... (Dr. Louis Pribyl).

Pusztai and Ewen insist
Stanley Ewen and Arpad Pusztais study suggesting potential health
risk from potatoes genetically modified to include the snowdrop lectin
GNA continues to be controversial (lectins are a type of plant protein).
In an exchange of letters published in The Lancet, Ewen and Pusztai defend
their methods and logic well, and point out that, although their findings
cannot be used to link GM crops with any specific disease risk, it adds
to the evidence that GM crops are not substantially equivalent
(pro-GM campaigners argue that they are) to the natural parent plants
the GM versions derived from.
The rats which ate natural potatoes from the same
batch that were genetically modified to include the snowdrop lectin GNA
for the study did not have the changes in the intestinal tract experienced
by the rats which ate the genetically modified sample. They mention two
other examples of non-equivalence. Monsantos own analyses of its
glyphosate-resistant soya found that it contained 28% more Kunitz trypsin
inhibitor, a known anti-nutrient and allergen. It also contained significantly
less phyto-oestrogens.
Because of this, Ewen and Pusztai argue that all GM crops should be first
tested for toxicity and unexpected side effects (which is not done at
present) and wonder why the stricter testing now recommended for future
GM crops is not thought to be necessary, retrospectively, for GM crops
already granted licenses given that they have now been recognised as inadequately
tested.
Some critics argue that the presence of additional GNA in GM crops is
of minor concern on the basis that humans already consume lectins in their
diet and that we know which are harmless and which toxic. Ewen and Pusztai
disagree. They point out that snowdrops have never been part of the human
diet and that, although the specific lectin (GNA) is already in our diet
(from, for instance, onions and leeks), levels are 100 times lower than
in snowdrops and, indeed, than the levels which would be required in GM
crops to repel insects.
They also point out that human consumption of GNA varies daily whereas,
as a principal tool of genetic engineering, it would become present in
many of our basic foods, leading to chronic exposure. They remind their
critics that, whereas other forms of lectins break down quite easily in
the human gut (lectins from peas or beans, for instance, are 70% destroyed
within an hour), GNA does not (99% remained after one hour).

More stringent tests needed
Erik Millstone and colleagues (Science and Technology Policy Research)
argue that the outcome of any genetic engineering is unpredictable, and
that therefore the most stringent animal-based tests will always be needed.
They cite the genetic engineering of oilseed rape, which led to the unexpected
discovery of enzymes and regulatory mechanisms affecting the way the body
processes lipids (fatty substances), and Roundup Ready soy bean, which
tolerated more glyphosate pesticide as planned, but also had reduced tolerance
to heat because of unpredicted changes to its lignin content. This made
it less suitable for use in many less industrially developed countries,
one of the arguments used to justify its development.
(Ed.- Lignin provides rigidity in plants and, together
with cellulose, forms the woody cell walls of plants and the cementing
material between them).

New Labours ethical foreign policy is called into question by its

for LIDCs. Its Department of Trade and Industry has also indirectly provided
funding to the International Service for the Acquisition of Biotechnology
Applications (ISAAA), an organisation which transfers agri-biotech applications
from more industrially developed countries to LIDCs, particularly proprietary
technology from the private sector. ISAAAs funders also include Monsanto,
AgrEvo, Novartis and Pioneer Hi-Bred, so, essentially, UK taxpayers

Super salmon
Biologists in the UK and US are genetically engineering salmon to grow
quicker and larger by introducing the human growth hormone gene hGH. As
yet no-one has started to produce them commercially. Two researchers from
Purdue University in Indiana (US), William Muir and Richard Howard, wanted
to test the long-term effects of such engineering. Genetically-modifying
Japanese Medaka fish (a fish widely used in research), they also created
faster and greater growth, and higher levels of eggs in the females. The
weakness of the GM fish, however, was that only two thirds survived to
reproductive age.
Aware of several studies showing that larger fish,
including salmon, attract up to four times as many mates as their smaller
rivals, Muir and Howard turned to computer modelling to predict what might
happen to the salmon population. The prediction was that, because the
GM fish would pass on their short-life genes to 80% of the population,
it would be extinct within 40 generations. Muir comments, You have
the very strange situation where the least fit individual in the population
is getting all the matings - this is the reverse of Darwins model.

super salmon is imminent in the UK.

GM by the back route
While some progress has been made to ensure that products containing GM
ingredients are labelled as such, one major way by which consumers may
take in GM produce has been totally ignored - GM crops in animal feed.
GM crops have been used in UK animal feed for the last three years. Over
half of the worlds 70 million acre GM crop is fed to farm animals
- cattle, pigs and poultry - and Scottish farmed salmon. Because, so far,
the US has refused to separate GM maize and soya from natural maize and
soya, farmers are unable to say whether their animal feed has GM ingredients
or not.
Nobody knows the consequences of feeding GM feed to farm animals, nor
of humans later eating the animals or their products (e.g. milk, cheese,
fats). If any research has been done it has not been made public. The
UK Ministry of Agriculture, Fisheries and Foods (MAFFs) animal
feed unit is reported to be very worried indeed and responded
to two applications from Monsanto to sell two new GM products to animal
feed producers by calling for full toxicology tests.
Of particular concern are antibiotic-resistant marker genes in GM crops.
The British Medical Association believes that they are a completely
unacceptable risk, however slight, to human health. The Royal Society,
The UK Governments Advisory Committee on Novel Foods and Processes,
and the National Farmers Union agree. They fear that these genes will
increase resistance to antibiotics in both animals and humans.
Some scientists have argued that any GM DNA in animal feed will be destroyed
by (i) the silaging process, (ii) the feed production process, and (iii)
passing through the animals gut. The first two assumptions are seriously
questioned by the findings of tests undertaken by Leeds University on
behalf of MAFF. They found that neither silaging nor current heat treatment
practice would break down DNA. (Current heat treatment is carried out
at temperatures of 85°C or below. Dry heat and steam heat processes
at 95°+ for at least five minutes would be necessary.)
The third assumption - that DNA cannot pass intact through an animals
gut - has now been disproved. Dutch research predicts that 6% of the genes
in GM tomatoes would survive, and recent research published in The Lancet
showed that the snowdrop GNA lectin (the gene for which has been spliced
into experimental GM crops) binds strongly with human white blood cells
(a key component of the immune system). The Open Universitys Dr.
Mae-Wan Ho confirms that DNA can survive passage through the gut, readily
finding its way into the bloodstream and into all kinds of cells. Once
inside the cell, the DNA may insert itself into the cells genetic
material causing all manner of disturbances, including cancer.

Breeding resistance
Insects which have developed a resistance to pesticides produced by GM
plants tend to mate with each other rather than with non-resistant ones,
thus firmly establishing a resistant strain in the environment. The tendency
was found in moths which had become pesticide-resistant. Their larvae
take five days longer to hatch, thus missing the boat as regards non-resistant
faster-hatching potential partners.

Biotech heads for the trees
The Worldwide Fund for Nature (WWF) fears that GM trees may lead to silent
forests devoid of insects, flowers and birds. It is concerned that GM
trees may be more for the profit of a few than for the benefit of humanity
at large, and that not enough is known about their potential effect on
the environment.
Trees are being genetically modified to reduce lignin content (to make
them easier to pulp for paper production), to grow rapidly, to resist
pests and rot, or to be sterile. There have been 166 trials on 24 species
of GM trees since 1988. Of the 116 trials to date, 70 have been in the
US, 31 in Europe and 5 in Britain. The numbers are increasing, with 44
in 1998 alone. The WWF is concerned that commercial planting could begin
at any time in China, Chile and Indonesia, and calls for a global moratorium
until safety concerns have been properly addressed.
The problems around GM trees are the same as for GM crops, but bigger.
Pollen from GM pines could carry 375 miles rather than 3. The longer life
of trees also creates far greater potential for environmental damage.
The WWF report states: A combination of time and location factors
would allow escaped GM trees engineered for fast, aggressive growth to
become invasive weeds with the ability to out-compete naturally occurring
vegetation for sunlight, water and nutrients.
There is also the concern that GM tree plantations will increase the use
of fertilisers and pesticides.
WWF has called on its network of 100 companies who have already pledged
to only use timber from sustainable sources to ban GM wood products. Sainsburys
- one of these companies - has already taken the pledge.

Genetically engineered insulin
Thousands of diabetics transferred from animal insulin to genetically-engineered
(GE) insulin in the early 90s are still unaware that they have been
put under a far higher risk of death. Many doctors are also unaware of
the problem. The reason? The British Diabetics Association suppressed
a report it itself had commissioned because it considered it too
alarmist.
Worse, many doctors who have become aware of the problem have still not
returned their patients to animal insulin because they believe that it
is no longer available. The two companies manufacturing GE insulin (by
feeding nutrients to e-coli bacteria) deny that there is any danger. Anecdotal
evidence from 3,000 diabetics who have suffered because of GE insulin
casts doubt:
50% said that they had no early warning
of passing out with hypos (hypoglycaemic episodes) with
the GE insulin
25% said that hypos were more frequent
20% said that hypos were more severe
13% said they passed out at night
5% suffered convulsions
10% had memory loss
9% were unable to concentrate
There was also strong evidence that the problems
were reversible. 99% of those who returned to animal insulin reported
improvements.

GE briefing
Genetically engineered foods contain genes derived
from pigs, fish, insects, viruses and bacteria. The first ones to have
appeared are tomatoes, corn, soya products, milk products, yeast and oils.
This range will be further extended to replace hundreds of traditional
varieties of fruit and vegetables. Many geneticists have warned that these
products may permanently damage human health. The reasons genetically-engineered
foods may be dangerous are:
Given the huge complexity of genetic
coding no-one can possibly predict the effects of introducing new genes
into any organism, nor the effects on the health of any person who eats
it. The transposed gene may react differently in its new host, the original
genetic intelligence of the host may be disrupted or the genes of the
host and the transposed gene may combine together with unpredictable
effects.
Biotechnologists claim that their manipulations are no different
from natural genetic changes but Nature would never allow the cross-species
transfers that are being achieved today, e.g. between pigs and plants,
fish and tomatoes. These may allow diseases and weaknesses to cross
species with unpredictable effects.
Biotechnology companies claim that their products are safe and
controllable. In fact the risks have been scientifically assessed as
unlimited. Unlike chemical or nuclear contamination gene pollution cannot
be cleaned up. The toxic effects of genetic mistakes will be passed
on to all future generations of a species.
Biotechnology companies say that the risks posed by their products
are similar to the risks posed by all foods, but experience has already
shown that genetically engineered products create dangerous new allergens
and toxins into foods which were previously safe. Genetically engineered
tryptophan (a food supplement that aids sleep) killed 30 people and
permanently disabled 1500 more.
Genetic research shows that many diseases have their origins
in tiny imperfections in genetic coding. Tinkering with the genetic
code in any way may upset the delicate balance between our physiology
and the foods we eat.
Biotechnology companies claim that governmental regulatory bodies
will protect public health (although they were unable to do this with
DDT, thalidomide, L-tryptophan, bovine growth hormone and BSE.)
After introduction into plants, bacteria,
insects and other animals new genetic information may cross into related
life forms through processes such as cross-pollination, or displace
existing species from the ecosystem with disastrous effects, like klebsiella
bacteria.
UK research institutions have little protection to ensure that
experimental genetically engineered organisms are not escaping (e.g.
seeds on the wind or by birds). No person, farm or country can isolate
themselves from the possible effects of genetic manipulation.
Transnational biotechnology companies already control large segments
of the worlds food supply (including food patents, seed companies).
Almost every food we eat will contain genetically modified ingredients
within a few years. Compared to the slow evolution over thousands of
years that has produced our traditional foods this represents a radical
change in our environment with which the human body may not be able
to cope.

or installing safeguards. In Poland carp with human genes have been swimming

Hundreds of tons of Toblerone were recalled from
stores after a routine check found that they contained illegal genetically
modified soya bean materials in the lecithin (an emulsifying agent). The
manufacturers, Kraft-Jacobs-Suchard, were shocked and stated that they
had been assured by their German supplier that the lecithin was free of
genetically modified organisms (GMOs).
(This demonstrates three things: it IS possible
to detect genetically-modified organisms in foodstuffs, contrary to earlier
claims from the US; GMOs can be hidden in the smallest ingredients in
food; commercial motives make it extremely difficult to trust suppliers
(or suppliers of suppliers - Ed.)
