GMO protagonists promote the image that they are only speeding up the natural

crossbreeding used by farmers for millennia by inserting the new gene with the

desired trait directly into the new organisms. They further assert that there is no

evidence of any adverse health effect from the consumption of GMO foods as they

are substantially equivalent to non-GMO foods. This distortion of the facts needs to

be corrected.

The Natural Breeding Misconception

One critical issue is that multiple genes are being transferred across kingdoms and

species such as bacteria, viruses, plants and animals in ways that do not occur by

natural breeding methods.

All living things are classified according to a ranking system that starts with species.

Closely related species are grouped together under a rank that is called a Genus.

Closely related Genera (the plural of genus) are grouped together under the rank of

Family. Closely related Families are grouped together under the rank of Order. There

are seven ranks. Starting with the highest they are: kingdom, phylum or division,

class, order, family, genus, species.

Plants, Animals, Fungi, Viruses and Bacteria belong to separate Kingdoms. Natural

breeding can take place between some species that belong to the same genus and

very occasionally between species of different genera. However species that belong

to different families do not breed and definitely species that belong to different

Kingdoms such as plants, animals, fungi, bacteria and viruses do not breed in nature.

Plants for example do not breed with animals, bacteria or viruses.

Genetic engineering allows for the transfer of multiple genes between Kingdoms in a

way that can never occur naturally. This is something that has never occurred before

and it creates a new frontier with many uncertainties due to science’s limited

understanding about genetics.

The Single Gene Misconception

The other great misconception is that researchers are only inserting one new gene.

At this stage science is not sophisticated enough to insert a single gene and get it to

work. To overcome this problem, scientists have to combine the gene with the

desired trait (such as herbicide tolerance or pesticide production) with other genes

that will make it work (promoter genes). Researchers also insert genes that help

them to identify if the new gene is working within the chromosome (marker genes).

This becomes a complex construction of transgenes, known as a gene cassette, that

can come from bacterial, viral, fish, plant and other sources.

Inserting the Gene Sequence

Another misconception is that the gene is neatly inserted into the cell. Genes are

grouped together inside the cell in long strands call chromosomes. Researchers use

what can be best described as a shotgun approach when they push new genes into a

chromosome. They either shoot the genetic material into the target cells, insert it

after weakening the cell membrane with an electric shock/chemical, or use a

modified microorganism such as a virus or bacteria to infect the target cell with the

new genes. The problem with these approaches is that the researchers do not know

if genes have been inserted into a chromosome, if there are multiple copies, if they

will work and how they will work.

Antibiotic Resistance Marker Genes

The most common method of discovering if the new gene will work involves using

Antibiotic Resistance Marker Genes. In the current generation of commercially

released GMOs, these genes come from bacteria that are resistant to antibiotics. The

marker genes are attached to the gene with the desired trait (herbicide resistance as

an example) and they are shot or infected into the target cells. These cells are then

cultured and an antibiotic is added. The cells that live have adopted the new genes

as they are resistant to the antibiotic.

These are then grown out as plants. The problem with these plants is that every part

of the plant has genes for antibiotic resistance. Many scientists and medical

professionals have expressed concerns about these genes being horizontally

transferred into the gut and mouth bacteria of humans and animals eating genetically

modified food. They are worried that this could create bacteria that are resistant to

the antibiotics needed to cure infections.

Horizontal gene transfer is where microorganisms take up genes directly through

their cell walls rather than by the normal method of reproduction. It has been shown

to occur with the antibiotic resistant super bugs. (Shoemaker et al. 2002)

When the potential danger of this was pointed out to the genetic scientists they

dismissed it as impossible. Several studies have since shown that these antibiotic

resistance genes can be transferred to bacteria in as little as two hours after eating

genetically modified food.

New Scientist in July 2002 reported on a scientific experiment that showed that this

can happen to bacteria in the human digestive system: For the first time, it has been

proved that bacteria in the human gut can take up DNA from genetically modified

food. (Coghlan 2002)

Currently every commercially released GMO plant has the antibiotic resistance genes

in every cell. They should be withdrawn from commercial production for this reason

alone, given the rise in antibiotic resistant human pathogens.

The Cauliflower Mosaic Virus Promoter (CaMV 35S)

When foreign DNA is inserted into organisms, three things usually happen. The most

common one is that the foreign DNA is digested to provide energy and building

blocks for the cell. It can also be rejected. The other response is to close over the

foreign DNA and deactivate it.

All of these responses are defence mechanisms to overcome attacks by pathogens

(disease). The host organism defends itself by getting rid of the foreign proteins. This

is the reason why transplant recipients have to take anti-rejection drugs. When

organisms detect foreign DNA a whole range of responses, collectively known as the

immune system, can be activated to repel or destroy the invaders.

When foreign genes are shot/infected into a cell, they tend to be digested, rejected or

closed over. Either way this means that the target organism will not have the desired

trait from the new gene.

To overcome this, genetic scientists build a construction, called a gene cassette, with

a section of the cauliflower mosaic virus that is called CaMV 35S promoter. The

CaMV gives the signal that activates or promotes the new gene. It ensures that the

gene is active so that its desired trait, like herbicide resistance, works in the new

plant.

Problems with the CaMV 35S

There are several problems with the CaMV. Every current GMO plant is part virus.

Every cell of their bodies contains the active section of a virus. With billions of these

plants now released into the environment, many scientists believe that there is a

great risk of horizontal transfer of the viral genetic code from GMO plants into

invading viruses, creating new virulent transgenic viruses. (Ho et al. 1999, Ho et al.

2009, Ho 2013)

In a paper published in the peer reviewed scientific journal, Microbial Ecology in

Health and Disease, Ho et al. (1999) wrote: ‘It has been known for some time that

recombination can occur between different CaMV viral strains in plants (19), between

different homologous parts of an integrated CaMV viral sequence in transgenic

plants (20) and between an integrated transgene and an infecting virus (21).’

The scientists further stated: ‘It means, in effect, that recombination of the CaMV

promoter elements with dormant, endogenous viruses may create new infectious

viruses in all species to which the transgenic DNA is transferred.’ (Ho et al. 1999)

When GMO scientists and researchers are questioned on this the standard reply is

that the cauliflower mosaic virus is harmless and doesn’t affect humans. Many

harmless viruses change into forms that can be serious. The various forms of the flu

are the classic example. Seventy years ago AIDS and Ebola were restricted to

monkeys and didn’t affect humans. SARS is a slightly modified common cold virus

and is now a seriously fatal disease with the potential for massive epidemics.

According to the journal Nature, April 2003: ‘In a simple overnight experiment,

researchers transformed a coronavirus that is lethal to cats into one that infects

mouse cells by replacing a single gene. The result strengthens the idea that the

SARS coronavirus might have arisen when an animal and human virus met and

swapped genes, says the study’s lead scientist’ (Pearson 2003)

The fact is no scientist can predict what would happen if transgenic viruses and

bacteria emerged from GMO plants. It was only a short time ago these same

scientists were saying pollen drift from GMOs would not affect nearby crops and that

the horizontal transference of antibiotic resistant genes from GMOs into gut

microorganisms was not possible. Ho et al. (1999) concluded that ‘Horizontal transfer

of the CaMV promoter not only contributes to the known instability of transgenic lines

(30), but has the potential to reactivate dormant viruses or creating new viruses in all

species to which it is transferred, particularly in view of the modularity and interchangeability

of promoter elements (8).’

Adverse health effect from GMOs

The GMO industry states that there is no evidence that the consumption of GMOs

has resulted in any adverse health effects in animals or humans. They state that they

are substantially equivalent to non-GMOs so that any concerns are considered as

irrational emotional concerns that are not validated by science. The industry literature

is a classic case of cherry picking data by ignoring a substantial body of evidence

showing a range of adverse reaction to GMOs in published studies.

Zdziarski et al. 2014 conducted a meta review of all the long-term published

comparison feeding studies of GM produce that contains the three most common

specific traits found in commercialized GM crops: herbicide tolerance via the EPSPS

gene and insect resistance via cry1Ab or cry3Bb1 genes.

The researchers only found 21 studies for nine (19%) out of the 47 crops approved

for human and/or animal consumption. They could find no relevant peer reviewed

studies on the other 38 (81%) approved crops. They further found that most of the

studies (76%) were performed after the crop had been approved for human and/or

animal consumption, with half of these being published at least nine years after

approval, which showed that overwhelming majority of GM crops have been

approved without published peer reviewed feeding and safety studies. Of equal

concern, the researchers found inconsistencies in the methodologies and a lack of

defined criteria for outcomes that would be considered toxicologically or

pathologically significant. Critically, they found a lack of transparency in the methods

and results, which made comparisons between the studies difficult. They stated:

‘The evidence reviewed here demonstrates an incomplete picture regarding the

toxicity (and safety) of GM products consumed by humans and animals.’ (Zdziarski et

al. 2014)

This study clearly shows that GM crops are being approved for animal and human

food despite a lack of published evidence based scientific feeding studies to show

that they are safe. By not requiring these studies to generate evidence of safety,

regulators are in effect approving GM crops on the basis of data free assumptions.

Seralini et al. (2011) published a study that reviewed 19 studies of animals fed with

GMO soy and corn in the peer reviewed scientific journal Environmental Sciences

Europe. The studies covered more that 80% of the GMO varieties that are widely

cultivated around the world.

Their review found significant levels of negative effects to kidneys and livers in the

animals that were fed GMOs. The scientists stated: ‘…the kidneys were particularly

affected, concentrating 43.5% of all disrupted parameters in males, whereas the liver

was more specifically disrupted in females (30.8% of all disrupted parameters).’

(Seralini et al. 2011)

One of the key conclusions is that the current testing methodologies (small sample

sizes, inadequate doses, inappropriate controls), length of feed trials (only 90 days)

and the parameters measured (lack of toxicological testing and data) are insufficient

to evaluate the health problems that are caused by diets of GMOs. The scientists

clearly stated that this lack of proper testing protocols is socially unacceptable in

terms of consumer health protection.

Substantially non-equivalent

Regulatory authorities use a basic chemical analysis of a GM variety and compare

this with it closest non-GM variety. If this chemical composition is much the same, the

GM variety is declared as substantially equivalent and suitable for uncontained

commercial release.

Bohn et al. (2014) were able to discriminate between organic, conventional and GE

soybeans without exception, based on vitamin, fat and protein content. Furthermore,

they were able to distinguish GM soybeans from both conventional and organic by

their glyphosate and AMPA (glyphosate degradation product) residues, as well as

substantial non-equivalence in numerous compositional characteristics of soybeans.

The researchers stated, “Using 35 different nutritional and elemental variables to

characterise each soy sample, we were able to discriminate GM, conventional and

organic soybeans without exception, demonstrating ‘substantial non-equivalence’ in

compositional characteristics for ‘ready-to-market’ soybeans” (p. 207).

Multiple Health Problems

A peer-reviewed study published by Swanson et al. (2014) found a strong correlation

between the rise in the production of GMOs, use of glyphosate and 22 chronic

diseases in the USA such as diabetes, obesity, lipoprotein metabolism disorder,

Alzheimer’s, senile dementia, Parkinson’s, multiple sclerosis and autism.

The study showed how this rise in glyphosate exposure is due to the increase in

glyphosate tolerant GMO crops in the USA and cited numerous scientific studies

showing how glyphosate can cause or increase susceptibility to these diseases.

Seralini et al. (2011) published a study that reviewed 19 studies of animals fed with

GMO soy and corn in the peer reviewed scientific journal Environmental Sciences

Europe. The studies covered more that 80% of the GMO varieties that are widely

cultivated around the world.

Their review found significant levels of negative effects to kidneys and livers in the

animals that were fed GMOs. The scientists stated: ‘…the kidneys were particularly

affected, concentrating 43.5% of all disrupted parameters in males, whereas the liver

was more specifically disrupted in females (30.8% of all disrupted parameters).’

(Seralini et al. 2011)

One of the key conclusions is that the current testing methodologies (small sample

sizes, inadequate doses, inappropriate controls), length of feed trials (only 90 days)

and the parameters measured (lack of toxicological testing and data) are insufficient

to evaluate the health problems that are caused by diets of GMOs. The scientists

clearly stated that this lack of proper testing protocols is socially unacceptable in

terms of consumer health protection.

GM Maize Linked to Cancer, Liver and Kidney Disease

The only lifetime comparison feeding study found that rats fed a diet that contains a

proportion of GM maize or minute residues of Roundup has resulted in significantly

higher increases of tumours, kidney disease, liver damage and other negative health

effects.

The study led by Professor Gilles-Eric Seralini and published in Food and Chemical

Toxicology has found that both the GM maize and Roundup acted as endocrine

disrupters and resulted in the females dying 2 – 3 times more than the control

animals. (Seralini et al. 2014)

The females that were fed either GM maize or non-GM maize with minute roundup

residues developed large mammary tumours almost always more often than and

before the controls. All the non-control females, except for one that had ovarian

cancer, had mammary hypertrophies (enlarged mammary glands) and in some cases

hyperplasia with atypia (nodules in the mammary glands).

These pictures are examples of the types of mammary gland tumours (breast cancer)

that the scientists found in the rats. Photos permission of Seralini et al 2014.

The pituitary gland was the second most disabled organ and the sex hormonal

balance was modified in females fed with the GMO and Roundup treatments.

The treated males presented 4 times more large palpable tumours (large enough that

they can be felt by hand) than controls and these occurred up to 600 days earlier.

The treated males had liver congestions and necrosis that were 2.5 – 5.5 times higher

than the controls as well as marked and severe kidney nephropathies (kidney

damage) that were also generally 1.3 – 2.3 greater than the controls.

This study was the first 2-year feeding trial conducted on rats designed to see the

effects of a GM diet over an animal’s lifetime. Currently, no regulatory authority

requests mandatory chronic animal feeding studies to be performed for edible GMOs.

However, studies consisting of 90-day rat feeding trials have been conducted by the

biotech industry even though there is no requirement to do this.

The standard comparison of the chemical composition used for establishing

substantial equivalence of the GM maize used in this study (NK603) revealed no

particular difference and consequently it was classified as substantially equivalent.

Similarly, a 90-day feeding trial showed no significant differences between the

controls and the rats fed the GM maize variety.

The results of the 2 year feeding study show that the current regulatory system for

approving GM crops for consumption are inadequate for assessing the effects of

eating these foods over a normal lifetime.

Uterine and stomach damage in pigs

Currently there is only one large sample size published peer reviewed comparison

study of a GM diet in pigs. This is significant as pigs have a gastrointestinal tract and

other organs that are physiologically similar to humans. Carman et al. (2013) found

that the GM diet was associated with gastric and uterine differences in pigs. GM-fed

pigs had uteri that were 25% heavier than non-GM fed pigs. GM-fed pigs had a

higher rate of severe stomach inflammation with a rate of 32% of GM-fed pigs

compared to 12% of non-GM-fed pigs.

Carman et al. (2013) stated: ‘Even though pigs are physiologically similar to humans,

particularly for gastrointestinal observations, very few toxicology studies have been

conducted on them for GM crops (Walsh et al., 2012a). In doing this study, we not

only used animals that were physiologically similar to humans, but we also weighed

and internally examined organs and took blood for biochemical analysis. We further

used a large enough sample size (168 pigs, 84 per group) to be able to determine

statistical significance for key toxicological outcomes.’

GM Soy has adverse effect on the offspring

One of the most concerning issues is the negative effect that occurs in the offspring

of rats and mice that are fed GM diets. These effects include increased infant

mortality, reduced litter sizes and reduced body weights of the offspring.

In experimental trials male and female mice were fed GM soy and then mated. The

early stage embryos (4-8 cells) showed a temporary decrease in gene expression.

This was not found in embryos whose parents ate natural non-GM soy. (Oliveri 2006)

There is strong body of science that shows that subtle changes to gene expression in

embryos can cause permanent negative effects in the development of offspring.

A Russian rat study conducted by Dr Irina Ermakova and colleagues found that

offspring of rats fed in GM soy had higher levels of mortality than rates fed with non-

GMO soy. (Ermakova 2006)

The scientists noted that babies of the rats that were fed GMO diets developed at

slower rate, had lower weights and looked markedly different than the babies of rates

that were fed non-GMO diets. Images permission of Jeffery M Smith

Difficulties with conception

Dr. Ermakova and her colleagues found that the mated offspring of the GM group did

not conceive. This is a serious concern that needs to be fully investigated with more

scientific research. (Ermakova 2006)

GM soy damages testicles

One of the possible causes for the developmental differences and the lack of fertility

in the offspring of mice that are fed GMOs is that several studies have found that

GMO diets cause structural changes to the testicles. A study published in the

European Journal of Histochemistry found that testicles of mice fed GM soy had

altered structures and functions that influenced sperm development. (Vecchio 2004)

GM potatoes damaged rats

Studies published in highly respected medical journal The Lancet and in the peer

reviewed Journal Nutrition and Health by Dr Arpad Pusztai showed multiple serious

problems with rats that were fed GM potatoes. The scientific studies found that the

rats that were fed on the GMO developed smaller brains, livers and testicles, had

partial atrophy of the liver and damage to immune system. The studies showed that

the rats developed potentially precancerous cell growth in the linings of their stomach

and intestinal walls. (Pusztai 2002, Ewen and Pusztai 1999)

The picture on the left is the intestinal wall of a rat that was fed on non-GMO potato.

growths are potentially precancerous and can lead to bowel cancer, which has

become one of the forms of cancer that is increasing in humans.

GMO soybean products

There are several animal studies that show range of adverse effects from consuming

GMO soybean products. Mice fed GMO soy for 8 months had a profound drop in the

amount of digestive enzymes produced by their pancreas. (Malatesta 2002 a,

Malatesta 2003). Researcher also found that the liver cells were damaged or

misshapen and there was altered gene expression. They found that there was a

higher rated metabolic activity that suggested that the liver was reacting to a toxic

insult. (Malatesta 2002 b)

more irregular in the GM-fed mice. Images permission of Jeffery M Smith.

nucleoli was also misshapen in the GM-fed mice. Images permission of Jeffery M

BT Corn

In a study by Monsanto made public because of a lawsuit, rats fed Bt corn developed

signs of liver and kidney toxicity. These included kidney inflammation and kidney

lesions, and decreased kidney weight. The latter symptom is typically related to blood

pressure problems. They also developed increased basophiles that are related to

allergies. The study showed that they had increased lymphocytes or white blood cells

that are part of the immune system indicating a reaction to infection or possibly

disease. There was a 10% increase in blood sugar and decreased immature red

blood cells by 50%. (Burns 2002, Seralini 2007)

GM Corn

When Liberty Link corn was fed to chickens, twice the number of chickens died. But,

the test conducted by the industry was designed so poorly; even a doubling of the

death rate was not statistically significant. (Leeson 1996)

FlaverSavr Tomato

The first GM crop that was looked at by the US FDA was the FlavrSavr tomato,

engineered to have a longer shelf life. Calgene, its producers, were the only

company to give the United States FDA raw feeding study data. They did a study

with rats but the rats refused to eat the tomato.

They force fed rats the FlavrSavr tomato for 28 days. 7 of 20 rats developed stomach

lesions. Another 7 of 40 died within 2 weeks. In the documents made public,

scientists said that the study doesn’t show “a reasonable certainty of no harm.” The

FDA did not block the introduction of the tomato.

The company had created two lines of the GM tomato, both with the same gene

inserted. One was associated with these high rates of lesions and deaths, the other

was not. The company voluntarily decided to market the one that was not associated

with the rat problems.

This also provides an example of how the same crop inserted with identical genes,

may have very different results. And it provides a good example of what can go

wrong with GMOs. (FDA 1993, Pusztai 2002)

GM pea

In Australia, CSIRO researchers took a gene from a kidney bean that produced

proteins that acted as a pesticide, and inserted it into peas to kill the pea weevil. The

researchers did an allergic-type test on mice that no other GMO food crop developer

had done before.

When they exposed mice to the pesticide proteins from the kidney beans, it caused

no reaction. They expected the same to happen when mice were exposed to the

“same” protein produced by the transgene inside the peas. In fact, the amino acid

sequence was identical in both proteins as the one produced by both the bean and

the pea. But the mice developed an inflammatory response to the protein produced in

the GMO peas. It was an immune type response that was very dangerous,

suggesting that the peas might create a deadly anaphylactic shock or other types of

immune or inflammatory reactions in humans.

To understand why the GMO pea caused the severe allergy problems, the

researchers looked very carefully at the protein structure and found that the sugars

that had attached to it had a slightly changed pattern. They said it was the slightly

changed pattern of the sugars that made the peas harmful.

The problem is that the potentially deadly GM peas had already passed all the allergy

tests that are normally used to get GM foods on the market. The only reason they

were stopped was because the crop developer had chosen to use a mice study that

had never been used on any other GM food crop. This shows that the regulatory

system, as practiced, is a failure, and may be letting deadly allergens on the market.

To the credit of the CSIRO they discontinued bringing the GMO pea to commercial

production. (Prescott 2005)

GM L-tryptophan and human deaths

In the late 1980s an epidemic that killed about 100 Americans and caused another 5-

10,000 to fall sick or become permanently disabled was traced to an amino acid

health supplement called L-tryptophan. L-tryptophan is a common amino acid that is

found in milk products. For many years it was extracted from milk and sold as health

supplement to for aiding sleep and calming mood disorders.

A Japanese company Showa Denko started to produce L-tryptophan from genetically

engineering the bacteria. The epidemic was traced back to the L-tryptophan that was

produced from the genetically engineering the bacteria. (Mayeno and Gleich 1994)

Effect on mothers and children

The greatest concern for humans is that the toxin from pesticide producing GMOs

can be found in bloodstream of women and their unborn children. A Canadian study

published in the scientific journal, Reproductive Toxicology, found the pesticide toxin

from GMO crops in the blood samples of women and their unborn babies.

The GMO toxin was found in 93 percent of maternal blood samples and of greater

concern in 80 percent of fetal blood samples. These women were eating the typical

Canadian diet. (Aris and Leblanc 2011)

A peer-reviewed study published in Journal of Applied Toxicology that researched the

combination of the GMO-produced Bt toxin pesticides and Roundup found that they

altered the normal life cycle of cells in human organs. The researchers concluded: “In

these results, we argue that modified Bt toxins are not inert on nontarget human

cells, and that they can present combined side effects with other residues of

pesticides specific to GM plants.” (Mesnage at al. 2013)

Given the evidence of the damaging changes to the offspring of animals fed a GMO

diet, the Canadian study should be the cause of great concern amongst health

professionals and regulators to ensure that the GMO foods that are currently being

consumed are not doing damage to our future generations.

Conclusion

Zdziarski et al. showed there are no studies showing the safety of overwhelming

majority (81%) the main commercially released GMOs. Furthermore they showed

that the existing studies are inadequate to determine that GMOs are safe for human

and animal feed. The data from the published studies cited in this article show that

the assertion by the GMO industry that there is no evidence of damaging health

effects from the consumption of GMO foods is clearly wrong. The data show that the

current situation where there is no mandatory requirement for feeding studies to be

conducted for GMO’s before their commercial release should be seen as neglect of

good science by regulatory authorities. The policy that GMOs are ‘substantially

equivalent’ to non-GMOs and therefore do not need testing is a data free assumption

given that Bohn et al. were able to discriminate GM, conventional and organic

soybeans without exception, demonstrating ‘substantial non-equivalence’ in

compositional characteristics for ‘ready-to-market’ soybeans and that Séralini et al.

were able to demonstrate considerable adverse health outcomes from GM foods

deemed as substantially equivalent. The results of the 2 year feeding study show that

the current regulatory system for approving GM crops for consumption are

inadequate for assessing the effects of eating these foods over a normal lifetime. It

shows that the voluntary 90-day trials used by industry are inadequate to test for

adverse effects and therefore should be disregarded as evidence of safety. The

results of the Carman et al. study shows the need to test these foods on animals that

have gastrointestinal tracts and other organs that are physiologically similar to

humans.

The current testing methodologies (small sample sizes, inadequate doses,

inappropriate controls), length of feed trials (only 90 days) and the parameters

measured (lack of toxicological and histopathological testing and data) are

insufficient to evaluate the health problems that are caused by diets of GMOs. The

research scientists clearly stated that the lack of proper testing protocols is

unacceptable in terms of human health protection.

Until all the commercially released GMOs are tested on animals with gastrointestinal

tracts and other organs that are physiologically similar to humans and that these

tests evaluate the effects of eating these foods over a lifetime, the GMO industry and

the government regulators have no published peer reviewed scientific evidence that

the consumption of GMO foods are safe for humans and animals. In reality they are

using data free assumptions that these novel foods are safe and given that there is a

substantial body of published studies showing adverse health effects, this should be

seen as totally unacceptable.
