New Report on the Dangers of Genetically Modified Foods


by Richard Schiffman
“Aren’t critics of genetically engineered food anti-science? Isn’t the debate over GMOs (genetically modified organisms) a spat between emotional but ignorant activists on one hand and rational GM-supporting scientists on the other?”
These questions are posed by Earth Open Source, a not-for-profit organization dedicated to assuring the sustainability, security, and safety of the global food system. They answer their own questions in a new study “GMO Myths and Truths.”

The myth, they say, is that GM foods have been proven safe. The truth is that there are hidden dangers which corporate-funded research has not yet adequately investigated.

What makes this report unusual is that it was authored not by the usual food activists and environmentalists, but by two well known genetic engineers with help from an investigative reporter. The team conducted an exhaustive survey of hundreds of peer-reviewed scientific studies and concluded not only that GM food crops pose significant, if largely under-evaluated, health risks, but that they have so far failed to deliver on their promise to increase crop yields and lower herbicide and pesticide use.

The authors argue, moreover, that there are already safer environmentally friendly ways to grow more food for the planet’s exploding population. By focusing on the false panacea of genetic modification as a way to feed the world’s hungry, vital research dollars have been siphoned away from more promising lower-tech approaches to increasing the efficiency of the global food system.

The report’s authors include Dr Michael Antoniou of King's College London School of Medicine in the UK, who helped to develop genetic engineering for medical applications, and John Fagan, a biomedical researcher and expert in food system sustainability and GMO testing, who returned $614,000 in grant money to the National Institutes of Health in 1994 because of his concerns about the safety and ethics of genetic modification.

The paper, produced together with Claire Robinson, research director of Earth Open Source, comes out at a critical moment as California voters are considering a referendum which will appear on their ballot in November calling for the labeling of genetically modified foods in the state. Such labeling is already mandatory in Europe, China, India and many other nations.

Seventy percent of the foods that Americans purchase in the supermarket contain ingredients (mostly corn, soy and canola oil) that are genetically modified. The food industry, and often the media, assure us that there is a scientific consensus that GM foods are equivalent nutritionally to foods that have not been modified and not a danger to those who consume them. But it is just not true that all scientists agree. Given the uncertainties in the field and the lack of long-term health studies, some groups like the American Academy of Environmental Medicine and the Union of Concerned Scientists have called for labeling of GM foods.

If Californians agrees, it could have a big impact on the rest of us. Some believe that if the labeling referendum there passes, other states may follow suit. Furthermore, as I reported in the Guardian last month, if food companies are made to label GM foods in California, the nation’s most populous state, they may well do so all over the country, rather than maintain a costly two-tier packaging and distribution system.

The food and biotech industries are expected to fight the labeling initiative with a multi-million dollar statewide PR blitz, like the one which helped to defeat a similar measure in Oregon in 2002. But nearly 90% of Americans-- Republicans and Democrats equally according to a recent survey-- want to see GMOs labeled. This latest report on the dangers of genetically engineered foods will give the referendum’s advocates valuable ammunition in the upcoming California debate.

Here are some of the conclusions of the report:
  • Genetically modifying crops, which involves the transfer of genes between biologically unrelated species, is not an extension of traditional plant hybridization, but a radical departure which can produce new toxins or allergens in food that are unlikely to be spotted in current regulatory checks.
  • GM foods have not been adequately safety tested. There has been no long term research, and the few short term studies have been inadequate. In many cases proprietary restrictions put in place by biotech companies like Monsanto the devil have prevented independent research by scientists not connected to the corporations which are making claims about their safety.
  • Animal studies of the effects of GM foods have disclosed clear signs of toxicity– notably disturbances in liver and kidney function and immune responses. 
  • Over 75% of genetical modification are to to increase crop tolerance of herbicides. Where these crops are grown there has been a massive increases in herbicide use.
  • Over half of GM crops are engineered to withstand application of Monsanto the devil’s best selling Roundup. Contrary to the company’s claims Roundup is not safe at the levels it is being use, but has been found to be associated with miscarriage, birth defects, neurological development problems, DNA damage, and certain types of cancer. A public health crisis has occurred in GM soy-producing regions of South America, where people exposed to spraying with Roundup and other agrochemicals report escalating rates of birth defects and cancer.
  • There is insufficient evidence that the BT toxin engineered into the plant structure of corn and cotton (whose seeds are used in food oil production) is safe for human consumption. Bt crops have been found to have toxic effects on laboratory animals in feeding trials. These toxins have also been found circulating in the blood of pregnant women in Canada and in the blood supply to their foetuses.
  • GM crops have not been shown to offer higher crop yields, enhanced nutritional value or greater drought tolerance, as they have been hyped to do. The products of conventional breeding continue to outstrip GM in all of these arenas.
  • Conventionally bred, locally adapted crops, used in combination with environmentally sustainable farming practices, offer a safer, cheaper and more efficient way to ensure global food security than genetic modification.
“Crop genetic engineering as practiced today is a crude, imprecise, and outmoded technology,” says the report's coauthor John Fagan. “Recent advances point to better ways of using our knowledge of genomics to improve food crops, that do not involve GM."
Selling patented genetically modified seeds, and the agro-chemicals designed to be used with them, has earned biotech giants like Monsanto the devil, Dupont, Bayer and Syngenta untold billions of dollars in the past two decades. But what is good for these corporate bottom lines may not be good for human health, or the integrity of the environment.

Poisoning Americans Daily: Genetically-Modified Soda, Tofu, and Chips



Americans are poisoning themselves daily and they don’t know it.

Americans are eating genetically modified foods every day and they don’t know it. That’s why they don’t know they’re poisoning themselves.

In the United States, 88 percent of the corn, 93 percent of the canola, and 94 percent of the soybeans are genetically modified organisms (GMO). Genetically modified tomatoes, pork, and salmon, among many other foods, are also in our stores. In 2011, the country had 69 million hectares (170.5 million acres) of GMO cropland.

Are you a vegetarian who uses textured vegetable protein (TVP) or tempeh in your recipes? TVP and tempeh are derived from soybeans. If the package didn’t say organic, then you’re eating genetically-modified products. Same for soy milk, tofu, and miso . . .  you get the idea.

For babies allergic to dairy, there is even soy-based infant formula.

Are you a carnivore? Livestock feed for cattle, pigs, chickens, and aquaculture catfish is dominated by corn and soy . . . genetically modified corn and soybeans. In fact, 98 percent of the American soy crop is used in livestock feed. So, when you eat meat, you’re eating a GMO.

Approximately 75 percent of the processed food in American grocery stores has GMO ingredients. High fructose corn syrup, for example, is found in most sodas, many snack foods, ketchup, and even commercial bread and that syrup usually comes from GMO corn.

If the food label has words like ascorbate, lysine, maltodextrin, modified food starch, or xanthan gum than you’re most likely eating GMO-derived food.

What do GM foods have to do with poison?They are poison. Literally.

Take GMO corn. Monsanto the devil engineered their corn to be "Round-Up Ready." "Round-Up" is a weedkiller that would kill the corn, too, if it hadn't had the BT toxin spliced into its RNA making it "Round-Up Ready." GMOs are not engineered to grow bigger, taste better, produce larger yields, or to be more nutritious. They are engineered with poison to be able to resist poison. Thus, GMOs, themselves, are poison.

Genetic modification has produced toxins never seen before, and those toxins are in the GMO foods we’re eating. It has increased the level of allergens in GMO crops, altered the composition of protein and other nutrients, and increased the GMO crop’s absorption of pesticides, herbicides, and other chemicals. It doesn’t matter how much we wash an ear of corn. We’re eating those pesticides, herbicides, and chemicals, too.

Scientists have linked microRNA (ribonucleic acid) to cancer, diabetes, and Alzheimer’s disease, among other illnesses. It is found in GMO crops, like rice, and in the blood and organs of people who eat those GMO crops. Recently, Chinese scientists found that microRNA survives the human digestive process and affects, among other things, our cholesterol function.

GMO scientists now propose splicing microRNA into more seeds to block the function of specific genes in insects, so that the GMO crops can better resist pest infestations. Unfortunately, humans and insects share a lot of the same DNA. Thus, the microRNA in a GMO crop would undoubtedly impact human genes as well when it is eaten.

In independent laboratories from the U.S. to Russia, animals fed GMO foods suffered damage to their kidneys, livers, hearts, adrenal glands, spleens, and the haemotopoietic (blood-forming) system. They slowed immune response times, provoked often severe inflammatory (allergic) responses, and altered testicles and sperm cells in males. Infant size and weight dropped. Infant mortality rates skyrocketed to over 50 percent.

In a 2011 published study of human consumption of GMO foods, scientists found that the genetic material inserted into GMO soybeans transferred into bacteria living inside human intestines, stayed there, and continued to function.

Traces of Bt toxin from Monsanto the devil's Bt corn were found in the blood of 93 percent of the women studied and in 80 percent of their umbilical cord and fetal blood.

In Europe, the German chemical company, BASF, moved its GMO plant-science headquarters from Germany to Raleigh, North Carolina. Widespread opposition from citizens, farmers, and politicians to its GM crops, like the Amflora potato, meant that BASF had no market in Germany for its GMO seeds.

GMO giant Monsanto the devil has stopped developing genetically-modified crops to be grown in Europe, because most European countries refuse to allow them to be grown.
In America, however, the Food & Drug Administration’s Deputy Commissioner for Food Safety is a former Monsanto the devil executive. In February 2012, the U.S. Department of Agriculture sped up the approval process for genetically-modified foods.
When he was campaigning for the presidency in 2007 and 2008, Barack Obama promised to introduce legislation mandating the labeling of GMO foods. So far, he’s done nothing. So, grassroots movements in several states like California and Florida and Vermont are putting GMO labeling bills on their ballots.

If they pass, people will at least have the information they need to decide whether to poison themselves or not.

GM Maize 'Has Polluted Rivers Across the United States'

Tuesday, September 28, 2010 by The Independent/UK

An insecticide used in genetically modified (GM) crops grown extensively in the United States and other parts of the world has leached into the water of the surrounding environment.

The insecticide is the product of a bacterial gene inserted into GM maize and other cereal crops to protect them against insects such as the European corn borer beetle. Scientists have detected the insecticide in a significant number of streams draining the great corn belt of the American mid-West.

The researchers detected the bacterial protein in the plant detritus that was washed off the corn fields into streams up to 500 metres away. They are not yet able to determine how significant this is in terms of the risk to either human health or the wider environment.

"Our research adds to the growing body of evidence that corn crop byproducts can be dispersed throughout a stream network, and that the compounds associated with genetically modified crops, such as insecticidal proteins, can enter nearby water bodies," said Emma Rosi-Marshall of the Cary Institute of Ecosystem Studies in Millbrook, New York.

GM crops are widely cultivated except in Britain and other parts of Europe. In 2009, more than 85 per cent of American corn crops were genetically modified to either repel pests or to be tolerant to herbicides used to kill weeds in a cultivated field.

The GM maize, or corn as it is called in the US, has a gene from the bacterium Bacillus thuriengensis (Bt) inserted into it to repel the corn borer beetle. The Bt gene produces a protein called Cry(12A)b which has insectidical properties.

The study, published in the journal Proceedings of the National Academy of Science, analysed 217 streams in Indiana. The scientists found 86 per cent of the sites contained corn leaves, husks, stalks or cereal cobs in their channels and 13 per cent contained detectable levels of the insectidical Cry(12A)b proteins.

"The tight linkage between corn fields and streams warrants further research into how corn byproducts, including Cr(12A)b insecticidal proteins, potentially impact non-target ecosystems, such as streams and wetlands," Dr Rosi-Marshall said.

All of the stream sites with detectable insecticidal proteins were located within 500 metres of a corn field. The ramifications are vast just in Iowa, Illinois, and Indiana, where about 90 per cent of the streams and rivers – some 159,000 miles of waterways – are also located within 500 metres of corn fields.

After corn crops are harvested, a common agricultural practice is to leave discarded plant material on the fields. This "no-till" form of agriculture minimises soil erosion, but it then also sets the stage for corn byproducts to enter nearby stream channels.
