GM Foods: New study shows unborn babies could be harmed

Mortality rate for new-born rats six times higher when mother was fed on a diet of modified soya

Women who eat Genetically Modified foods while pregnant risk endangering their unborn babies, startling new research suggests.

The study – carried out by a leading scientist at the Russian Academy of Sciences – found that more than half of the offspring of rats fed on modified soya died in the first three weeks of life, six times as many as those born to mothers with normal diets. Six times as many were also severely underweight.

The research – which is being prepared for publication – is just one of a clutch of recent studies that are reviving fears that GM food damages human health. Italian research has found that modified soya affected the liver and pancreas of mice. Australia had to abandon a decade-long attempt to develop modified peas when an official study found they caused lung damage.

And last May this newspaper revealed a secret report by the biotech giant Monsanto, which showed that rats fed a diet rich in GM corn had smaller kidneys and higher blood cell counts, suggesting possible damage to their immune systems, than those that ate a similar conventional one.

The United Nation’s Food and Agriculture Organisation held a workshop on the safety of genetically modified foods at its Rome headquarters late last year. The workshop was addressed by scientists whose research had raised concerns about health dangers. But the World Trade Organisation is expected next month to support a bid by the Bush administration to force European countries to accept GM foods.

The Russian research threatens to have an explosive effect on already hostile public opinion. Carried out by Dr Irina Ermakova at the Institute of Higher Nervous Activity and Neurophysiology of the Russian Academy of Sciences, it is believed to be the first to look at the effects of GM food on the unborn.

The scientist added flour from a GM soya bean – produced by Monsanto to be resistant to its pesticide, Roundup – to the food of female rats, starting two weeks before they conceived, continuing through pregnancy, birth and nursing. Others were given non-GM soyaand a third group was given no soya at all.

She found that 36 per cent of the young of the rats fed the modified soya were severely underweight, compared to 6 per cent of the offspring of the other groups. More alarmingly, a staggering 55.6 per cent of those born to mothers on the GM diet perished within three weeks of birth, compared to 9 per cent of the offspring of those fed normal soya, and 6.8 per cent of the young of those given no soya at all.

“The morphology and biochemical structures of rats are very similar to those of humans, and this makes the results very disturbing” said Dr Ermakova. “They point to a risk for mothers and their babies.”

Environmentalists say that – while the results are preliminary – they are potentially so serious that they must be followed up. The American Academy of Environmental Medicine has asked the US National Institute of Health to sponsor an immediate, independent follow-up.

The Monsanto soya is widely eaten by Americans. There is little of it, or any GM crop, in British foods though it is imported to feed animals farmed for meat.

Tony Coombes, director of corporate affairs for Monsanto UK, said: “The overwhelming weight of evidence from published, peer-reviewed, independently conducted scientific studies demonstrates that Roundup Ready soy can be safely consumed by rats, as well as all other animal species studied.”

What the experiment found

Russian scientists added flour made from a GM soya to the diet of female rats two weeks before mating them, and continued feeding it to them during pregnancy, birth and nursing. Others were give non-GM soya or none at all. Six times as many of the offspring of those fed the modified soya were severely underweight compared to those born to the rats given normal diets. Within three weeks, 55.6 per cent of the young of the mothers given the modified soya died, against 9 per cent of the offspring of those fed the conventional soya.

Genetically engineered crops contain latent pesticides that are activated when eaten by consumers
Sep 07 2006
Source: NewsTarget

According to a recent article from the Institute for Responsible Technology, certain varieties of herbicides used on genetically modified (GM) crops — though inactive inside the plants they protect — can be re-activated after consumption and cause toxic reactions.

Herbicide tolerance (HT) is a common trait in roughly 71 percent of all GM crops, which are mostly comprised of corn, soy, cotton and canola. HT crops tend to make a lot of money for biotech companies, since farmers who buy HT seeds are required to purchase that company’s brand of herbicide as well.

The herbicide used in many GE crops is derived from a natural antibiotic found in soil, which produces specialized enzymes that transform from an antibiotic to a non-toxic form called NAG (N-acetyl-L-glufosinate). The enzymes are then inserted into the DNA of GM crops, so that when the crop is sprayed with herbicides, the plant transforms the herbicide into non-toxic NAG — essentially, the plant is able to protect itself from the toxic chemicals that kill the weeds surrounding it.

However, recent animal studies have shown that after GM crops — which have accumulated high levels of NAG after several herbicide sprays — are consumed, stomach bacteria can re-transform NAG back into the toxic herbicide. Two rat studies found a 10 percent and a 1 percent rate of NAG conversion after consumption of HT crops.

According to a January 2006 report by the Environmental Protection Agency’s Office of the Inspector General, certain pesticides easily enter the brains of young children and fetuses, where they then destroy cells. Studies of mice embryos exposed to glufosinate resulted in reduced numbers of vital brain receptors, growth retardation, increased death rates and incomplete development of the forebrain.

Critics of GM crops urge the public to call on the EPA for more rigorous testing of genetically engineered crops, and for stricter labeling laws on GM products so consumers can more easily avoid them.

This article summarizes the findings in Jeffrey Smith’s “Genetic Roulette: The Documented Health Risks of Genetically Engineered Foods.”

Potential Health Hazards of Genetically Engineered Foods

by Stephen Lendman

Global Research, February 22, 2008

This article discusses the potential health risks of genetically engineered foods (GMOs). It draws on some previously used material because its importance bears repeating. It also cites three notable books and highlights one in particular – Jeffrey Smith’s “Genetic Roulette: The Documented Health Risks of Genetically Engineered Foods.” Detailed information from the book is featured below.

Genetically engineered foods saturate our diet today. In the US alone, over 80% of all processed foods contain them. Others include grains like rice, corn and wheat; legumes like soybeans and soy products; vegetable oils, soft drinks; salad dressings; vegetables and fruits; dairy products including eggs; meat, chicken, pork and other animal products; and even infant formula plus a vast array of hidden additives and ingredients in processed foods (like in tomato sauce, ice cream, margarine and peanut butter). Consumers don’t know what they’re eating because labeling is prohibited, yet the danger is clear. Independently conducted studies show the more of these foods we eat, the greater the potential harm to our health.

Today, consumers are kept in the dark and are part of an uncontrolled, unregulated mass human experiment the results of which are unknown. Yet, the risks are enormous, it will take years to learn them, and when we finally know it’ll be too late to reverse the damage if it’s proved conclusively that genetically engineered foods harm human health as growing numbers of independent experts believe. Once GM seeds are introduced to an area, the genie is out of the bottle for keeps. There is nothing known to science today to reverse the contamination already spread over two-thirds of arable US farmland and heading everywhere unless checked.

This is happening in spite of the risk because of what F. William Engdahl revealed in his powerfully important, well documented book titled “Seeds of Destruction: The Hidden Agenda of Genetic Manipulation.” It’s the diabolical story of how Washington and four Anglo-American agribusiness giants plan world domination by patenting animal and vegetable life forms to gain worldwide control of our food supply, make it all genetically engineered, and use it as a weapon to reward friends and punish enemies.

Today, consumers eat these foods daily without knowing the potential health risks. In 2003, Jeffrey Smith explained them in his book titled “Seeds of Deception.” He revealed that efforts to inform the public have been quashed, reliable science has been buried, and consider what happened to two distinguished scientists – UC Berkeley’s Ignacio Chapela and former Scotland Rowett Research Institute researcher and world’s leading lectins and plant genetic modification expert, Arpad Pusztai. They were vilified, hounded, and threatened for their research, and in the case of Pusztai, fired from his job for doing it.

He believed in the promise of GM foods, was commissioned to study them, and conducted the first ever independent one on them anywhere. Like other researchers since, he was shocked by his findings. Rats fed GM potatoes had smaller livers, hearts, testicles and brains, damaged immune systems, and showed structural changes in their white blood cells making them more vulnerable to infection and disease compared to other rats fed non-GMO potatoes. It got worse. Thymus and spleen damage showed up; enlarged tissues, including the pancreas and intestines; and there were cases of liver atrophy as well as significant proliferation of stomach and intestines cells that could be a sign of greater future risk of cancer. Equally alarming, results showed up after 10 days of testing, and they persisted after 110 days that’s the human equivalent of 10 years.

Later independent studies confirmed what Pusztai learned, and Smith published information on them in his 2007 book called “Genetic Roulette: The Documented Health Risks of Genetically Engineered Foods.” The book is encyclopedic in depth, an invaluable comprehensive source, and this article reviews some of the shocking data in it.

Compelling Evidence of Potential GMO Harm

In his introduction, Smith cites the US Food and Drug Administration’s (FDA) policy statement on GM food safety without a shred of evidence to back it. It supported GHW Bush’s Executive Order that GMOs are “substantially equivalent” to ordinary seeds and crops and need no government regulation. The agency said it was “not aware of any information showing that foods derived by these new methods differ from other foods in any meaningful or uniform way.” That single statement meant no safety studies are needed and “Ultimately, it is the food producer” that bears responsibility “for assuring safety.” As a consequence, foxes now guard our henhouse in a brave new dangerous world.

FDA policy opened the floodgates, and Smith put it this way: It “set the stage for the rapid deployment of the new technology,” allowed the seed industry to become “consolidated, millions of acres (to be) planted, hundreds of millions to be fed (these foods in spite of nations and consumers objecting, and) laws to be passed (to assure it).” The toll today is contaminated crops, billions of dollars lost, human health harmed, and it turns out the FDA lied.

The agency knew GM crops are “meaningfully different” because their technical experts told them so. As a result, they recommended long-term studies, including on humans, to test for possible allergies, toxins, new diseases and nutritional problems. Instead, politics trumped science, the White House ordered the FDA to promote GM crops, and a former Monsanto vice-president went to FDA to assure it.

Today, the industry is unregulated, and when companies say their foods are safe, their views are unquestioned. Further, Smith noted that policy makers in other countries trust FDA and wrongly assume their assessments are valid. They’re disproved when independent studies are matched against industry-run ones. The differences are startling. The former report adverse affects while the latter claim the opposite. It’s no secret why. Agribusiness giants allow nothing to interfere with profits, safety is off the table, and all negative information is quashed.

As a result, their studies are substandard, adverse findings are hidden, and they typically “fail to investigate the impacts of GM food on gut function, liver function, kidney function, the immune system, endocrine system, blood composition, allergic response, effects on the unborn, the potential to cause cancer, or impacts on gut bacteria.” In addition, industry-funded studies creatively avoid finding problems or conceal any uncovered. They cook the books by using older instead of younger more sensitive animals, keep sample sizes too low for statistical significance, dilute the GM component of feeds used, limit the duration of feeding trials, ignore animal deaths and sickness, and engage in other unscientific practices. It’s to assure people never learn of the potential harm from these foods, and Smith says they can do it because “They’ve got ‘bad science’ down to a science.”

The real kinds show GMOs produce “massive changes in the natural functioning of (a) plant’s DNA. Native genes can be mutated, deleted, permanently turned off or on….the inserted gene can become truncated, fragmented, mixed with other genes, inverted or multiplied, and the GM protein it produces may have unintended characteristics” that may be harmful.

GMOs also pose other health risks. When a transgene functions in a new cell, it may produce different proteins than the ones intended. They may be harmful, but there’s no way to know without scientific testing. Even if the protein is exactly the same, there are still problems. Consider corn varieties engineered to produce a pesticidal protein called Bt-toxin. Farmers use it in spray form, and companies falsely claim it’s harmless to humans. In fact, people exposed to the spray develop allergic-type symptoms, mice ingesting Bt had powerful immune responses and abnormal and excessive cell growth, and a growing number of human and livestock illnesses are linked to Bt crops.

Smith notes still another problem relating to inserted genes. Assuming they’re destroyed by our digestive system, as industry claims, is false. In fact, they may move from food into gut bacteria or internal organs, and consider the potential harm. If corn genes with Bt-toxin get into gut bacteria, our intestinal flora may become pesticide factories. There’s been no research done to prove if it’s true or false. Agribusiness giants aren’t looking, neither is FDA, consumers are left to play “Genetic Roulette,” and the few animal feeding studies done show the odds are against them.

Arpad Pusztai and other scientists were shocked at their results of animals fed GM foods. His results were cited above. Other independent studies showed stunted growth, impaired immune systems, bleeding stomachs, abnormal and potentially precancerous cell growth in the intestines, impaired blood cell development, misshaped cell structures in the liver, pancreas and testicles, altered gene expression and cell metabolism, liver and kidney lesions, partially atrophied livers, inflamed kidneys, less developed organs, reduced digestive enzymes, higher blood sugar, inflamed lung tissue, increased death rates and higher offspring mortality as well.

There’s more. Two dozen farmers reported their pigs and cows fed GM corn became sterile, 71 shepherds said 25% of their sheep fed Bt cotton plants died, and other reports showed the same effects on cows, chickens, water buffaloes and horses. After GM soy was introduced in the UK, allergies from the product skyrocketed by 50%, and in the US in the 1980s, a GM food supplement killed dozens and left five to ten thousand others sick or disabled.

Today, Monsanto is the world’s largest seed producer, and Smith notes how the company deals with reports like these. In response to the US Public Health Service concerning adverse reactions from its toxic PCBs, the company claims its experience “has been singularly free of difficulties.” That’s in spite of lawsuit-obtained records showing “this was part of a cover-up and denial that lasted decades” by a company with a long history of irresponsible behavior that includes “extensive bribery, highjacking of regulatory agencies, suppressing negative information about its products” and threatening journalists and scientists who dare report them. The company long ago proved it can’t be trusted with protecting human health.

In his book, “Seeds of Destruction,” Engdahl names four dominant agribusiness giants – Monsanto, DuPont, Dow Agrisciences and Syngenta in Switzerland from the merger of the agriculture divisions of Novartis and AstraZeneca. Smith calls these companies Ag biotech and names a fifth – Germany-based Bayer CropScience AG (division of Bayer AG) with its Environmental Science and BioScience headquarters in France.

Their business is to do the impossible and practically overnight – change the laws of nature and do them one better for profit. So far they haven’t independent because genetic engineering doesn’t work like natural breeding. It may or may not be a lot of things, but it isn’t sex, says Smith. Michael Antoniou, a molecular geneticist involved in human gene therapy, explains that genetic modification “technically and conceptually bears no resemblance to natural breeding.” The reproduction process works by both parents contributing thousands of genes to the offspring. They, in turn, get sorted naturally, and plant breeders have successfully worked this way for thousands of years.

Genetic manipulation is different and so far fraught with danger. It works by forcibly inserting a single gene from a species’ DNA into another unnaturally. Smith puts it this way: “A pig can mate with a pig and a tomato can mate with a tomato. But this is no way that a pig can mate with a tomato and vice versa.” The process transfers genes across natural barriers that “separated species over millions of years of evolution” and managed to work. The biotech industry now wants us to believe it can do nature one better, and that genetic engineering is just an extension or superior alternative to natural breeding. It’s unproved, indefensible pseudoscience mumbo jumbo, and that’s the problem.

Biologist David Schubert explains that industry claims are “not only scientifically incorrect but exceptionally deceptive….to make the GE process sound similar to conventional plant breeding.” It a smoke screen to hide the fact that what happens in laboratories can’t duplicate nature, at least not up to now. Genetic engineering involves combining genes that never before existed together, the process defies natural breeding proved safe over thousands of years, and there’s no way to assure the result won’t be a deadly unrecallable Andromeda Strain, no longer the world of science fiction.

The industry pooh-pooh’s the suggestion of potential harm, and unscientifically claims millions of people in the US and worldwide have eaten GM food for a decade, and no one got sick. Smith’s reply: How can we know as “GM foods might already be contributing to serious health problems, but since no one is monitoring for this, it could take decades” to find out. By then, it will be too late and some industry critics argue it already may be or dangerously close.

Today, most existing diseases have no effective surveillance systems in place. If GM foods create new ones, that potentially compounds the problem manyfold. Consider HIV/AIDS. It went unnoticed for decades and when identified, many thousands worldwide were infected or had died.

Then there’s the problem of linkage. In the US and many countries, GM foods are unlabeled so it’s impossible tracing illness and diseases to specific substances ingested even if thousands of people are affected. It can plausibly be blamed on anything, especially when governments and regulatory agencies support industry claims of reliability and safety.

It’s rare that problems like the L-Tryptophan epidemic of the late 1980s are identified, but when it was thousands were already harmed. L-Tryptophan is a natural amino acid constituent of most proteins and for years was produced by many companies including Showa Denko in Japan. The company then got greedy, saw a way to increase profits from a product designed to induce sleep naturally, and gene-spliced a bacterium into the natural product to do it. The result was many dozens dead, over 1500 crippled, and up to 10,000 afflicted with a blood disorder from a new incurable disease called Eosinophilia Myalgia Syndrome or EMS.

It’s a painful, multi-system disease that causes permanent scarring and fibrosis to nerve and muscle tissues, continuing inflammation, and a permanent change in a person’s immune system. It cost the company two billion dollars to settle claims. Hundreds have since died, in all likelihood from contracting EMS.

This is the known toll from a single product. Consider the potential harm with Ag biotech wanting all foods to be unlabeled GMOs worldwide and governments unable to balk because WTO Agreement on Agriculture (AoA) and Trade Related Intellectual Property Rights (TRIPS) rules deny them. They’re also prevented under WTO’s Sanitary and Phytosanitary Agreement (SPS). It states that national laws banning GMO products are “unfair trade practices” even when they endanger human health. Other WTO rules also apply – called “Technical Barriers to Trade.” They prohibit GMO labeling so consumers don’t know what they’re eating and can’t avoid these potentially hazardous foods.

The 1996 Biosafety Protocol was drafted to prevent this problem, and it should be in place to do it. Public safety, however, was ambushed by Washington, the FDA and the agribusiness lobby. It sabotaged talks and insisted biosafety measures be subordinate to WTO trade rules that apply regardless of other considerations, including public health and safety. The path is thus cleared for the unrestricted spread of GMO seeds and foods worldwide unless a way is found to stop it.

Independent Animal Studies Showing GMO Harm

Rats fed genetically engineered Calgene Flavr-Savr tomatoes (developed to look fresh for weeks) for 28 days got bleeding stomachs (stomach lesions) and seven died and were replaced in the study.

Rats fed Monsanto 863 Bt corn for 90 days developed multiple reactions typically found in response to allergies, infections, toxins, diseases like cancer, anemia and blood pressure problems. Their blood cells, livers and kidneys showed significant changes indicative of disease.

Mice fed either GM potatoes engineered to produce Bt- toxin or natural potatoes containing the toxin had intestinal damage. Both varieties created abnormal and excessive cell growth in the lower intestine. The equivalent human damage might cause incontinence or flu-like symptoms and could be pre-cancerous. The study disproved the contention that digestion destroys Bt-toxin and is not biologically active in mammals.

Workers in India handling Bt cotton while picking, loading, weighing and separating the fiber from seeds developed allergies. They began with “mild to severe itching,” then redness and swelling, followed by skin eruptions. These symptoms affected their skin, eyes (got red and swollen with excessive tearing) and upper respiratory tract causing nasal discharge and sneezing. In some cases, hospitalization was required. At one cotton gin factory, workers take antihistamines daily.

Sheep grazing on Bt cotton developed “unusual systems” before dying “mysteriously.” Reports from four Indian villages revealed 25% of them died within a week. Post mortems indicated a toxic reaction. The study raises questions about cottonseed oil safety and human health for people who eat meat from animals fed GM cotton. It’s crucial to understand that what animals eat, so do people.

Nearly all 100 Filipinos living adjacent to a Bt corn field became ill. Their symptoms appeared when the crop was producing airborne pollen and was apparently inhaled. Doing it produced headaches, dizziness, extreme stomach pain, vomiting, chest pains, fever, and allergies plus respiratory, intestinal and skin reactions. Blood tests conducted on 39 victims showed an antibody response to Bt-toxin suggesting it was the cause. Four other villages experienced the same problems that also resulted in several animal deaths.

Iowa farmers reported a conception rate drop of from 80% to 20% among sows (female pigs) fed GM corn. Most animals also had false pregnancies, some delivered bags of water and others stopped menstruating. Male pigs were also affected as well as cows and bulls. They became sterile and all were fed GM corn.

German farmer Gottfried Glockner grew GM corn and fed it to his cows. Twelve subsequently died from the Bt 176 variety, and other cows had to be destroyed due to a “mysterious” illness. The corn plots were field trials for Ag biotech giant Syngenta that later took the product off the market with no admission of fault.

Mice fed Monsanto Roundup Ready soybeans developed significant liver cell changes indicating a dramatic general metabolism increase. Symptoms included irregularly shaped nuclei and nucleoli, and an increased number of nuclear pores and other changes. It’s thought this resulted from exposure to a toxin, and most symptoms disappeared when Roundup Ready was removed from the diet.

Mice fed Roundup Ready had pancreas problems, heavier livers and unexplained testicular cell changes. The Monsanto product also produced cell metabolism changes in rabbit organs, and most offspring of rats on this diet died within three weeks.

The death rate for chickens fed GM Liberty Link corn for 42 days doubled. They also experienced less weight gain, and their food intake was erratic.

In the mid-1990s, Australian scientists discovered that GM peas generated an allergic-type inflammatory response in mice in contrast to the natural protein that had no adverse effect. Commercialization of the product was cancelled because of fear humans might have the same reaction.

When given a choice, animals avoid GM foods. This was learned by observing a flock of geese that annually visit an Illinois pond and feed on soybeans from an adjacent farm. After half the acreage had GM crops, the geese ate only from the non-GMO side. Another observation showed 40 deer ate organic soybeans from one field but shunned the GMO kind across the road. The same thing happened with GM corn.

Inserting foreign or transgenes is called insertional mutagenesis or insertion mutation. When done, it usually disrupts DNA at the insertion site and affects gene functioning overall by scrambling, deleting or relocating the genetic code near the insertion site.

The process of creating a GM plant requires scientists first to isolate and grow plant cells in the laboratory using a tissue culture process. The problem is when it’s done it can create hundreds or thousands of DNA mutations throughout the genome. Changing a single base pair may be harmful. However, widespread genome changes compound the potential problem manyfold.

Promoters are used in GM crops as switches to turn on the foreign gene. When done, the process may accidently switch on other natural plant genes permanently. The result may be to overproduce an allergen, toxin, carcinogen, antinutrient, enzymes that stimulate or inhibit hormone production, RNA that silences genes, or changes that affect fetal development. They may also produce regulators that block other genes and/or switch on a dormant virus that may cause great harm. In addition, evidence suggests the promoter may create genetic instability and mutations that can result in the breakup and recombination of the gene sequence.

Plants naturally produce thousands of chemicals to enhance health and protect against disease. However, changing plant protein may alter these chemicals, increase plant toxins and/or reduce its phytonutrients. For example, GM soybeans produce less cancer-fighting isoflavones. Overall, studies show genetic modification produces unintended changes in nutrients, toxins, allergens and small molecule metabolism products.

To create a GM soybean with a more complete protein balance, Pioneer Hi-Bred inserted a Brazil nut gene. By doing it, an allergenic protein was introduced affecting people allergic to Brazil nuts. When tests confirmed this, the project was cancelled. GM proteins in other crops like corn and papaya may also be allergenic. The same problem exists for other crops like Bt corn, and evidence shows allergies skyrocketed after GM crops were introduced.

Another study of Monsanto’s high-lysine corn showed it contained toxins and other potentially harmful substances that may retard growth. If consumed in large amounts, it may also adversely affect human health. In addition, when this product is cooked, it may produce toxins associated with Alzheimer’s, diabetes, allergies, kidney disease, cancer and aging symptoms.

Disease-resistant crops like zucchini, squash and Hawaiian papaya may promote human viruses and other diseases, and eating these products may suppress the body’s natural defense against viral infections.

Protein structural aspects in GM crops may be altered in unforeseen ways. They may be misfolded or have added molecules. During insertion, transgenes may become truncated, rearranged or interspersed with other DNA pieces with unknown harmful effects. Transgenes may also be unstable and spontaneously rearrange over time, again with unpredictable consequences. In addition, they may create more than one protein from a process called alternative splicing. Environmental factors, weather, natural and man-made substances and genetic disposition of a plant further complicate things and pose risks. They’re introduced as well because genetic engineering disrupts complex DNA relationships.

Contrary to industry claims, studies show transgenes aren’t destroyed digestively in humans or animals. Foreign DNA can wander, survive in the gastro-intestinal tract, and be transported by blood to internal organs. This raises the risk that transgenes may transfer to gut bacteria, proliferate over time, and get into cells DNA, possibly causing chronic diseases. A single human feeding study confirmed that genes, in fact, transferred from GM soy into the DNA gut bacteria of three of seven test subjects.

Antibiotic Resister Marker (ARM) genes are attached to transgenes prior to insertion and allow cells to survive antibiotic applications. If ARM genes transfer to pathogenic gut or mouth bacteria, they potentially can cause antibiotic-resistant super-diseases. The proliferation of GM crops increases the possibility. The CaMV promoter in nearly all GMOs can also transfer and may switch on random genes or viruses that produce toxins, allergens or carcinogens as well as create genetic instability.

GM crops interact with their environment and are part of a complex ecosystem that includes our food. These crops may increase environmental and other toxins that may accumulate throughout the food chain. Crops genetically engineered to be glufosinate (herbicide)resistant may produce intestinal herbicide with known toxic effects. If transference to gut bacteria occurs, greater problems may result.

Repeated use of seeds like Monsanto’s Roundup Ready soybeans results in vicious new super-weeds that need far greater amounts of stronger herbicides to combat. Their toxic residues remain in crops that humans and animals then eat. Even small amounts of these toxins may be endocrine disruptors that can affect human reproduction adversely. Evidence exists that GM crops accumulate toxins or concentrate them in milk or animals fed GM feed. Disease-resistant crops may also produce new plant viruses that affect humans.

All type GM foods, not just crops, carry these risks. Milk, for example, from cows injected with Monsanto’s bovine growth hormone (rbGH), has much higher levels of the hormone IGF-1 that risks breast, prostate, colon, lung and other cancers. The milk also has lower nutritional value. GM food additives also pose health risks, and their use has proliferated in processed foods.

Potential harm to adults is magnified for children. Another concern is that pregnant mothers eating GM foods may endanger their offspring by harming normal fetal development and altering gene expression that’s then passed to future generations. Children are also more endangered than adults, especially those drinking substantial amounts of rbGH-treated milk.

Conclusion

The above information is largely drawn from Smith’s “Genetic Roulette.” The data is startling and confirms a clear conclusion. The proliferation of untested, unregulated GM foods in the span of a decade is more a leap of faith than reliable science. Microbiologist Richard Lacey captures the risk stating: “it is virtually impossible to even conceive of a testing procedure to assess the health effects of (GM) foods when introduced into the food chain, nor is there any valid nutritional or public interest reason for their introduction.” Other scientists worldwide agree that GM foods entered the market long before science could evaluate their safety and benefits. They want a halt to this dangerous experiment that needs decades of rigorous research and testing before we can know.

Unchecked and unregulated, human health and safety are at risk because once GMOs enter the food chain, the genie is out of the bottle for keeps. Thankfully, resistance is growing worldwide, many millions are opposed, but reversing the tide won’t be easy. Washington and Ag biotech are on a roll with big unstated aims – total control of our food, making it all genetically engineered, and scheming to use it as a weapon to reward friends and punish enemies.

Smith is hopeful that people will prevail over profits. Hopefully he’s right because human health and safety must never be compromised. Resistance already halted the introduction of new crop varieties, and Smith believes that with enough momentum existing ones may end up withdrawn. He cites an example he calls a “Shift away from GM foods in the United States” in 2007. Leading it is an initiative launched last spring to remove GM ingredients from the entire natural food sector. It’s led by a coalition of natural food products producers, distributors and retailers along with the Institute for Responsible Technology (IRT). It’s called the Campaign for Healthier Eating in America, and its aims are big – to educate consumers about GM food risks and promote healthy alternatives through shopping guides.

A Pew survey reported that 29% of Americans, representing 87 million people, strongly oppose these foods and believe they’re unsafe. That’s a respectable start if backed up with efforts to avoid them, and more information how is at ResponsibleTechnology.org. Jeffrey Smith founded IRT in 2003 “to promote the responsible use of technology and stop GM foods and crops through both grassroots and national strategies.” It seeks safe alternatives and aims to “ban the genetic engineering of our food supply and all outdoor releases of (GM) organisms, at least until (or unless scientific opinion) believes such products are safe and appropriate based on independent and reliable data.”

IRT urges consumers to become educated about the risks, mobilize to combat them and act in our mutual self-interest. It’s beginning to happen, and Smith believes “there is an excellent chance that food manufacturers will abandon GM foods in the near future” if a public groundswell demands it. He ends his book saying: “Although GMOs present one of the greatest dangers, with informed, motivated people, it is one of the easiest global issues to solve.” Hopefully he’s right.

Dr. Jon Polling is a Neurologist. he is also the father of the most famous autistic child in America right now, Hannah Poling. In a historic concession, US Assistant Attorney General Peter Keisler and other Justice Department officials conceded on November 9 that Hanna “had a pre-existing mitochondrial disorder that was ‘aggravated’ by her shots, and which ultimately resulted in an ASD diagnosis” or, more specifically, in a diagnosis of “regressive encephalopathy (brain disease) with features consistent with autistic spectrum disorder, following normal development.”

While they did not go as far as saying that vaccination caused the neurological collapse of the previously healthy child, they did admit that for a child with a mitochondrial disorder, the shots could “aggrivate” a tendency toward autism. It is the first time that the US has come even this close to acknowledging the role of vaccines in any chronic neurological injury.

For the approximately 1000 cases behind this one, DR. JON POLING TO DR. STEVEN NOVELLA ON AGE OF AUTISM

PolingsBy Dr. Jon Poling, father of Hannah Poling.

OPEN LETTER TO DR. STEVEN NOVELLA
IN RESPONSE TO “Has the Government Conceded Vaccines Cause Autism?”

Dr. Novella,

Thank you for generating interesting discussion regarding my little girl,
Hannah Poling. I would like to give you additional information in order to
generate further productive discussions on this matter amongst the neurology
community. This information should assist you, Dr. DiMauro, and Dr.
Trevethan, who have also commented publicly, to formulate better theories as
to the significance of Hannah’s mitochondrial dysfunction in relation to her
autism.

1. Mito Dysfunction or Mito Disease? Chicken or Egg?

To begin with, I would like to point out that the spectrum of mitochondrial
dysfunction is probably considered more broad and complex than the spectrum
of neurobehavioral abnormalities seen with autism. Dysfunction of the
mitochondria, specifically dysfunction of the oxidative phosphorylation
pathway, most likely contributes, but may not be the cause of many
diseases—including Parkinson’s disease, Friedreich’s Ataxia, Alzheimer
disease, etc. Thus, it is probably incorrect to refer to mitochondrial
dysfunctional and mitochondrial disease interchangeably. Indeed, the role of
the dysfunctional mitochondrial are yet to be clarified in these diseases.
Thus, I will refer to Hannah’s metabolic condition as a mitochondrial
dysfunction, not a mitochondrial disease.

2. Mito Genetic Finding? Mito mtDNA ‘red herring’ ?

ADDITIONAL GENETIC TESTING NOT AVAILABLE IN THE J CHILD NEUROL CASE REPORT:
Dr. Shoffner performed genetic testing on both Hannah’s muscle and her
mother’s leukocytes subsequent to our case report. Hannah (muscle mtDNA) and
her mother (leukocyte mtDNA) were both found to be HOMOPLASMIC for the mtDNA
T2387C transition mutation.
Our analysis of this genetic finding in the mtDNA was significantly
different than those of other physicians that I’ve seen in scientific blogs
or commentary. I suspect it would have been fatal to both Hannah and her
mother if this homoplasmic mutation was pathogenic since (as I am sure you
are aware) the mutation is on the 16S ribosomal subunit which is highly
conserved. Thus, this mutation probably represents a benign polymorphism
rather than pathogenic mutation. It is unlikely, but possible, that the
mutation is significant to Hannah, but in such a case, it must work in
concert with other nuclear genes to cause her mitochondrial dysfunction. To
our knowledge, this point mutation has not been reported in cases similar to
Hannah’s.

3. Encephalitis? Metabolic Encephalopathy? Or “Regressive Encephalopathy
with Features of Autism Spectrum Disorder”

The other interesting term you used was encephalitis rather than
encephalopathy. We are not sure that she had an “-itis” but we did clearly
document a regressive encephalopathy based on not only our parental
reporting, but also based on the pediatrician’s documents, affidavits from
other family members, and the growth curve measurements (injury pattern).
Early on in the regression we did note back arching (opisthotonus), fever,
and disrupted sleep. Although fever occurred a lumbar puncture was not
performed.

An interesting developing story in autism research is the
immune/inflammatory connection. In her senior resident thesis, Dr. Anne
Comi, a former JHU colleague, along with Dr. Andy Zimmerman, reported, the
increased prevalence of autoimmune disease in families of autistic
offspring. Interesting, Hannah also has a maternal family history of
autoimmune disease. Dr. Carlos Pardo, another one of my former chief
residents, along with Andy and Dr. Vargas, published a beautiful study in
the Archives of Neurology, demonstrating neuroinflammation on autopsy of
brain samples and inflammation cytokine markers in the CSF of individuals
with Autism. The interesting thing was that inflammation was demonstrated in
autopsy specimens from adults as old as 44 years of age. The conclusion was
that further research would be required to determine if inflammation was a
primary disorder in autism or; alternatively, if inflammation and microglial
activation was secondary to neurodegeneration. Dr. Sudhir Gupta at UC Irvine
has a nice model of how the two pathways of neuroinflammation and mito
dysfunction may not be mutually exclusive. This remains to be seen; however,
study of mitochondrial dysfunction and neuroinflammation hold the promise of
treatment development. The two avenues of research deserve funding at the
highest levels.

4. How many Hannah Polings are out there?

The short answer is that nobody knows. However, there is emerging data to
suggest that she is not alone.

Dr. Shoffner will be presenting his experience with 37 patients with
combined autism and mitochondrial dysfunction at the AAN meeting in Chicago
this April. 65% of his referrals are positive for mitochondrial dysfunction.
Of course, his yield is subject to referral bias as a mito expert, so the
prevalence of mitochondrial dysfunction in Autism is surely less than 65%.

The best estimate to date of the prevalence of mitochondrial dysfunction in
autistic patients comes from Oliviera et al. in a population of 120, 5 of 69
(or 7.2%) showed mitochondrial dysfunction. If this is generalized to the US
estimate of 1 million patients with ASDs, then the number of kids like
Hannah could be 72,000! Isn’t this worth further study?

Dr. Shoffner furthermore advocates, along with us, that vaccination is
important even for kids with mitochondrial dysfunction. I would argue that
you should not give nine at one time and that none of them should contain
Thimerosal (mercury).

5. Thimerosal—On or Off the Table?

I don’t want to dwell on mercury, as this theory is not why HHS conceded
Hannah’s case (imo). Dr. DiContanzo just wrote an interesting blog about how
his opinion of mercury in vaccines has changed
(http://drugs.about.com/b/2008/03/08/mercury-in-vaccines-and-autism-the-burd
en-of-proof-may-shift.htm).

My opinion is that mercury is a potent neurotoxin. Therefore, don’t inject
it into kids! Interestingly, basic research studies have shown that
Thimerosal toxicity occurs through mitochondrial pathways. Officials point
to the large epidemiology studies as proof that there is no link between
thimerosal and autism. However, these studies are not powered to disprove
the null hypothesis when considering that the mitochondrial autistic
population may be just a small percent of the case totals. Remember that
while the CDC sponsored Verstraten study is hyped as a negative study, it
DID find a statistically significant increase in childhood tics in those
exposed to higher doses of thimerosal.

6. Hannah was destined to regress? Or was she?

Some experts have already stated that ‘mitochondrial disease’ is
degenerative so the vaccine reaction was just the start of an inevitable
decline. This was neither the opinion of Dr. Richard Kelley at KKI nor Dr.
John Shoffner. In fact, the markers that led us down the mitochondrial trail
(inc AST but not ALT, low serum bicarbonate, and slight increased CK,
increase in the alanine to lysine ratio on PAA) are no longer present.
Furthermore, in our pilot study (unpublished but mentioned in the J child
neurol paper), Dr. Frye (the statistician for our study and also a child
neurologist) found a non-significant trend that AST decreased toward normal
with increasing age. With further studies we hoped to examine the hypothesis
that this abnormality may be representative of a developing/immature
biochemical pathway present in some children.

7. Triple Hit Hypothesis—#1Underlying genetic susceptibility #2Insult must
occur during specific developmental period #3 A certain vaccination or
combination thereof is the environmental trigger (?vaccine component like
thimerosal ?direct immune stim/fever reaction ?live virus reaction?)

The implication is that Hannah’s type of autism requires a genetic
susceptibility and properly timed insult to manifest disease. We have not
subjected Hannah to another muscle biopsy or re-examined ox phos functional
assays that were published in the paper. I can inform your readers though
that the serum biochemical markers have resolved, growth resumed and
continues along a normal trajectory, and there have been no other episodes
of regression since 2000. We are however left with autism and later in 2006,
epilepsy.
It is recommended that studies be initiated immediately to screen siblings
of cases to identify biochemical markers so as to identify potential
screening tests.

I agree with the mainstream that my daughter’s case has raised many
intelligent discussions and questions. I’m very proud of her for starting
this discussion. Our hope is that further research into this case and others
like it, we will be also to find screening tests to prevent what happened to
my daughter from happening to anybody else.

(Dr. Poling acknowledges the editorial comments and insightful suggestions
of Dr. Richard E. Frye. He also would like to declare his conflicts of
interest. First of all, he is the father of Hannah Poling. Dr. Poling has
also accepted consultancy or speakers honoraria from Pfizer, Eisai,
Ortho-McNeil, Biogen, Teva, Immunex (now Amgen), and Allergan.)

PS While I thought it useful to clarify some of the neurological issues
raised by the government’s concession of my daughter’s case, please
understand that I will not be able to respond to individual comments posted.
Thank-you. Jon

Natural Solutions Foundation is deeply concerned by the human experimentaion which vaccinations, some of which are genetically modified, are introduced into the food chain without labeling. Residues of drugs and vaccines are eaten and serve as unclear stimuli of various sorts on an experimental basis.

Since consumers are receiving experimental brews of vaccines, drugs and GMO components without fully informed consent, international human rights treaties are being violated and the statutory responsibility of various agencies, including the FDA, are likewise being violated and abrogated.

The Natural Solutions Foundation urges regulatory and legal change to protect consumers from inaccurate information about the wholesome nature of foods so treated and urges full and complete disclosure and informed consent before consumption of these highly altered foods.

As an example, pigs are heavily vaccinated and their flesh is then eaten without any labeling of the contents of that flesh. This is neither good public health nor consumer policy. The Natural Solutions Foundation urges changes in national and state laws and regulatory practices in the USDA, FDA, EPA, FTC and other relevant agencies to protect consumer rights and health.

Details the vaccines commonly given to pigs. Vaccination schedules vary by country. Source: The Pig Site, http://www.thepigsite.com/pighealth/article/41/vaccination

Vaccination
(66) Vaccines contain antigens from viruses, bacteria, bacterial toxins, or parasites. They are given to pigs, usually by injection, to stimulate an immune response which will protect the pigs against later natural infection with the organism from which the vaccine was derived. Most stimulate both a humoral response and a cell-mediated response.

Vaccines can be live, containing living organisms which will multiply in the pig, or inactivated, containing only killed organisms which will not multiply in the pig.

In live vaccines the organisms has usually been attenuated (i.e. its virulence has been reduced) so that although it will multiply in the pig it will not normally cause any cause disease. Examples are the PRRS vaccine (although some may cause mild reactions), aujeszky’s disease (pseudorabies) vaccines and classical swine fever vaccines. Live attenuated vaccines have the advantage that because they multiply in the pig they give a bigger antigenic stimulus resulting in stronger longer-lasting immunity. They have the disadvantage that they may die in wrong storage conditions (e.g. heat) or during dosing (e.g. by exposure to antiseptics or disinfectants) and are then useless. It is also important that they are stable and not able to return to full virulence.

Inactivated (dead) vaccines may contain whole organisms, antigenic parts of organisms or antigens which have been synthesised chemically. An example of a commonly used whole organism vaccine is the erysipelas vaccine. (In North America such vaccines are often called Bacterins).

For example : – Erysipelas vaccine

This is made by growing the erysipelas bacteria in a liquid nutrient broth (several strains may be used).

1. The bacteria are then killed.
2. A liquid or adjuvant is added to the bacterial suspension.
3. This produces the vaccine.
4. A predetermined number of bacteria are injected into the pig. The first dose (usually 2ml).
5. A 2nd dose is required to complete the immune response, usually given 14 to 24 days after the first.
6. 7 days after the second dose the pig is protected.

Synthesised antigen vaccines are still largely in the experimental stage.

The immunity produced by inactivated vaccines can be enhanced by adding substances or adjuvants such as aluminium hydroxide or certain types of oil. You should take care, however, if you use vaccines with oily adjuvants because they can cause serious local reactions if you accidentally inject yourself, e.g. your hand.

Inactivated vaccines may also contain toxins which have been modified so that they still stimulate an immune response but are no longer toxic to the animal. Toxins which have been modified in this way are called toxoids. The classic vaccine of this type is the tetanus toxoid which is used commonly in horses but rarely in pigs. In pigs, some of the E. coli vaccines against piglet diarrhoea and the clostridial vaccines against piglet dysentery also contain toxoids.

Live vaccines are usually ones where the gene for the actual production of disease is deleted (gene deleted vaccines). The vaccine response can be differentiated from the actual disease and thus carrier animals removed. An example would be Aujeszky’s disease or Pseudorabies vaccines.

Autogenous vaccines

Autogenous vaccines are bacterial vaccines that are manufactured from the specific pathogenic bacteria isolated from the diseased pig. They are usually made under a licence for use only on that farm. You should consult with your veterinarian. These are available from Salus (QP) Ltd.. They can be useful when serious disease outbreaks occur and standard commercial vaccines are not available.

Such vaccines could be made from most bacteria including :-

* Actinobacillus pleuropneumoniae
* E. coli
* Haemophilus parasuis
* Pasteurella
* Salmonella
* Streptococcus suis
* Staphylococcus hyicus (Greasy pig disease)

One drawback to vaccinating a herd is that you cannot then use blood tests to check whether the organism is present in the herd or not. All the pigs will test positive which has obvious implications for an eradication programme based on blood tests, for example the eradication of swine fever or aujeszky’s disease (pseudorabies). To get over this, gene-deleted vaccines have been developed. A part of the organism’s gene which codes for an antigen has been removed so that when the organism multiplies in the pig it does not stimulate antibodies against that antigen. Special blood tests can then distinguish between the array of disease antibodies and those stimulated by the vaccine. A new generation of such gene manipulated vaccines, and possibly also synthetic polypeptide vaccines, can be anticipated.

Autogenous vaccines are those prepared with infectious pathogens from the herd which is to be vaccinated. The causal organisms has to be isolated, grown up, killed, and made into a safe vaccine form. Autogenous vaccines may be useful when serious disease outbreaks occur and standard commercial vaccines are not available.

Vaccine usage

Fig.3-5 lists the pig diseases for which vaccines are available. This list is not exhaustive and some vaccines will be available in some countries and not in others. However they are used in most countries both to protect against disease and to assist in eradication programmes. Some examples of commercial vaccines available are shown in chapter 4 these are but a few of the many available.

Vaccines commonly used on pig farms throughout the world include erysipelas, parvovirus infection (SMEDI syndrome), E. coli diarrhoea, clostridial dysentery of piglets, enzootic pneumonia caused by Mycoplasma hyopneumoniae, necrotic pleuropneumonia caused by Actinobacillus pleuropneumoniae and atrophic rhinitis caused by toxigenic Pasteurella multocida. In many countries, vaccines against diseases, such as, salmonellosis, PRRS and TGE are also used depending on commercial availability.

In the European Union vaccination against classical swine fever has been stopped in a programme aimed at stamping the disease out. Vaccination against foot-and-mouth disease has also been stopped for a similar reason. Aujeszky’s disease (pseudorabies) virus is widespread everywhere in the EU except in the UK and Denmark. With the exception of these two countries vaccination is widely practised. A blanket vaccination regime for all herds is being applied in some countries such as the Netherlands in an attempt to build up a national herd immunity resulting in the eradication of the virus.

North America is free from FMD and CSF so vaccination is not practised but PR vaccines are widely used in conjunction with eradication programmes. Elsewhere in the world, the situation regarding these three diseases varies, so vaccination policies also vary.

The effectiveness of vaccines

This varies, because of the need to stimulate mucosal immunity locally. As mentioned earlier, vaccines given by injection against respiratory and intestinal disease are generally not as effective as those against systemic or generalised diseases. An exception to this is the vaccine for enzootic pneumonia (M. hyopneumoniae) because it stimulates cell-mediated immunity. If, however, they are fed or sprayed into the upper respiratory tract they may produce a stronger local immunity. The vaccine against piglet dysentery is a toxoid and if given routinely to sows in adequate doses is usually reasonably effective in providing passive protection via the colostrum.

Sometimes vaccines do not work particularly well on a farm and in such cases the following possibilities need to be considered:

* The vaccine was contaminated.
* The vaccine was not capable of producing the required immunity.
* The pig was already incubating the disease when it was vaccinated.
* The vaccine had been incorrectly stored. High temperatures reduce the effectiveness. (Always keep vaccines in a refrigerator but do not freeze).
* The vaccine had been exposed to sunlight.
* The vaccine had gone out of date.
* The needle and syringe were dirty or faulty.
* Chemical sterilisation destroyed the vaccine.
* The animal had inadvertently missed being vaccinated. This is particularly common with parvovirus vaccination in the gilt.
* Vaccine response was poor because there was maternal antibody present.
* The vaccine was deposited in fat and was not absorbed. Faulty injection techniques

The management of vaccines

* Check the expiry date.
* Store in a fridge.
* Monitor the temperature daily with a max/min thermometer. Freezing destroys vaccines.
* Don’t overstock the fridge.
* Don’t store food in the fridge.
* Follow the instructions.
* Ideally use a fresh needle for each pig but change at least every 5 pigs.
* Do not mix vaccines or medicines.
* Dispose needles in a sharps box.
* Clean out syringes immediately after use.
* Only use vaccines licensed in your country.
* Clean bottle tops before and after use.
