Round 2 for Biotech Beets
By ANDREW POLLACK

Each growing season, like many other sugar beet farmers bedeviled by weeds, Robert Green repeatedly and painstakingly applies herbicides in a process he compares to treating cancer with chemotherapy.

“You give small doses of products that might harm the crop, but it harms the weeds a little more,” said Mr. Green, who plants about 900 acres in beets in St. Thomas, N.D.

But next spring, for the first time, Mr. Green intends to plant beets genetically engineered to withstand Monsanto’s powerful Roundup herbicide. The Roundup will destroy the weeds but leave his crop unscathed, potentially saving him thousands of dollars in tractor fuel and labor.

For Mr. Green and many other beet farmers, it is technology too long delayed. And the engineered beets could pave the way for the eventual planting of other biotech crops like wheat, rice and potatoes, which were also stalled on the launching pad.

Seven years ago, beet breeders were on the verge of introducing Roundup-resistant seeds. But they had to pull back after sugar-using food companies like Hershey and Mars, fearing consumer resistance, balked at the idea of biotech beets. Now, though, sensing that those concerns have subsided, many processors have cleared their growers to plant the Roundup-resistant beets next spring.

It would be the first new type of genetically engineered food crop widely grown since the 1990s, when biotech soybeans, corn and a few other crops entered the market.

“Basically, we have not run into resistance,” said David Berg, president of American Crystal Sugar, the nation’s largest sugar beet processor. “We really think that consumer attitudes have come to accept food from biotechnology.”

A Kellogg spokeswoman, Kris Charles, said her company “would not have any issues” buying such sugar for products sold in the United States, where she said “most consumers are not concerned about biotech.”

If some other big food companies are now open to genetically modified sugar, though, they are not talking about it. Both Hershey and Mars declined to comment. “There’s just nothing we have to say on the topic,” a Mars spokeswoman said.

Many sugar refiners and seed developers also refused to comment, hewing to an industrywide plan to coordinate the introduction of the genetically engineered beets and carefully control what is said about them.

When it comes to genetically modified crops, there is a reason to keep one’s corporate head low — to avoid protests. Some opponents of biotechnology are only now getting wind that the sugar beets have been resurrected.

“When I first saw this I said, ‘No, it can’t be,’” said Ronnie Cummins, national director of the Organic Consumers Association. “I thought we had already dealt with this.”

His organization issued a call to arms and thousands of identical e-mail messages were sent to Mr. Berg at American Crystal Sugar warning that “profit margins of your company and its supporting farmers” would be hurt by consumer resistance.

Mr. Berg said he received 681 messages in a 24-hour period before having the e-mail blocked. He said he still believed that most consumers would accept biotech crops. Mr. Cummins, however, said he would next try to persuade consumers to pressure food companies to boycott the sugar. “I don’t think companies like Hershey are going to want any more hassles than they already have,” he said, referring to recent earnings pressure and management turmoil at the chocolate company.

About 10,000 American farmers grow sugar beets on about 1.3 million acres, mainly in Northern states from Oregon to Michigan. That makes the beets a minor crop compared with corn, at about 90 million acres, and soybeans, at almost 70 million.

And yet beets account for about half the nation’s sugar supply, with the rest coming from sugar cane. The sugar from beets and cane, generally considered interchangeable, is used in candies, cereals, cakes and numerous other products, although some food manufacturers have switched to high-fructose corn syrup, which is cheaper.

When genetically engineered versions of soybeans and corn — as well as cotton and canola — were introduced in the mid-1990s, farmers quickly adopted them. But opposition to genetically engineered crops then took hold, particularly in Europe. Food companies, fearing protests or loss of customers, pressured farmers not to grow the crops.

Sugar was not the only crop affected. Insect-resistant potatoes developed by Monsanto were withdrawn from the market in 2001 after fast-food companies resisted them. Monsanto gave up on developing Roundup-resistant wheat in 2004, in part because American wheat farmers feared losing exports. The rice industry, also heavily dependent on exports, has never grown herbicide-tolerant varieties.

Even if the situation has now changed for sugar, however, other crops might still meet resistance. For one thing, sugar is a refined product that contains no DNA or proteins, just the chemical sucrose. “While the sugar beet is genetically different, the sugar is the same,” said Luther Markwart, executive vice president of the American Sugarbeet Growers Association and co-chairman of the Sugar Industry Biotech Council.

By contrast, the foreign DNA and proteins in genetically modified wheat, rice or potatoes can be eaten by consumers, which at least theoretically raises food safety questions.

Moreover, only about 3 percent of American sugar is exported, Mr. Markwart said, compared with about half of wheat and rice.

The sugar industry’s organizational structure also helps. Virtually all sugar processors — the companies that buy the beets from farmers and then extract the sugar and sell it — are owned by the farmers themselves. That makes them more likely to accept the biotech crops than an independent processor might be.

Among farmers, demand for the Roundup Ready beets, as they are known, is expected to be strong. “The sugar beet growers are going to adopt this technology immediately,” said Alan G. Dexter, the extension sugar beet specialist at North Dakota State University and the University of Minnesota. In a survey he conducted, 57 percent of beet growers cited weeds as their biggest problem, with diseases the distant runner-up at 16 percent.

The seeds will be most attractive to those with the biggest weed problems. With a technology fee of a little more than $100 per 100,000 seeds paid to Monsanto, the genetically engineered seeds will cost at least twice as much as conventional seeds. That translates to about $50 to $65 in extra seed costs per acre.

But Duane Grant, who grows about 5,000 acres of sugar beets in Rupert, Idaho, said the extra seed outlays would be offset by other savings. He said his annual herbicide costs would drop to $35 an acre, from $70, and he would no longer have to hire migrant workers to pull weeds by hand, at a cost of $35 to $150 an acre.

Mr. Grant, who was designated by the national beet growers’ association as its spokesman on this issue, also said Roundup would have to be sprayed only two or three times during the spring-to-fall growing season, while the existing herbicides must be sprayed five times or more. The existing herbicides are decades old and some weeds have developed resistance to them, Mr. Grant said.

Some weed experts say there are also some weeds resistant to Roundup and its generic equivalent, glyphosate, as a consequence of the heavy use of the herbicide spurred by the proliferation of Roundup Ready crops. But such weeds are not found in beet fields, Mr. Grant said.

He said that with conventional beets, Roundup can be used only before the seedlings emerge from the ground, because after that the Roundup would kill them.

Bringing back the biotech beets took a long, coordinated effort involving Monsanto, seed companies, growers, processors and trade groups under the auspices of the Sugar Industry Biotech Council.

Rival seed companies all agreed to use seeds descended from a single genetic transformation done by Monsanto and KWS, a German seed company. That meant the industry had to win federal approval only once. The new genetically engineered sugar beet was reviewed by the Food and Drug Administration in 2004 and approved for unrestricted growing by the Agriculture Department in early 2005.

And before planting the beets, farmers have waited for approvals in other important markets. Just last month Europe approved the beets for food and feed use, although not for planting.

Because such foods would have to be labeled in Europe as containing genetically engineered ingredients, some American food companies might use cane sugar, which is not genetically modified, for products they export to Europe. But in the United States, foods containing sugar made from biotech beets would not have to be labeled.

The sugar beet industry conducted field trials in Idaho last year and Michigan this year. Mr. Grant, who was part of the Idaho test, said the biotech seeds actually had slightly higher yields and sugar output than very similar conventional varieties.

Some environmentalists say the use of Roundup on sugar beets could contribute to the growing problem of Roundup-resistant weeds. But the Agriculture Department said it expected little, if any, environmental effect from growing the beets.

One factor that could help keep the trait from spreading is that beets produce seeds only in their second year, after passing through a winter. So beets grown in most parts of the country never produce seeds, because farmers harvest beets every fall and plant new seeds the next spring.

But in California, beets stay in the ground through the winter and there are weeds that can mate with sugar beets. So growers there may be more cautious about the Roundup revolution.

“We have to make sure we don’t cause ourselves more problems than we’re curing,” said Ben Goodwin, executive manager of the California Beet Growers Association.

This is where they should be getting the sugar for alcohol for cars.
Not from corn which provides less sugar.

So, does that mean we need to switch to pure cane sugar now? Is C&H still cane? Are there other varieties? Sheesh.:confused:

Stock up on sugar now. It doesn't go bad. Write Hershey and Mars Companies. Tell them we won't buy their product if beet sugar is used.

Not a good article to come out just before people start buying Christmas candies and supplies for holiday cooking.

I'm glad I gave up sugar, colas and everything containing sugar - in an effort to avoid high fructose GM corn syrup. I'm losing weight, too.

Kelloggs already buys GM corn and soy. So why not sugar?

When are you going to boycott this poison? As long as it sells, they have no incentive to stop using it.

You folks are fearful and ignorant

(I won't say stupid, I won't I won't , I won't)

There is no difference in the sugars from Roundup Ready plants and "normal" plants.
NONE.

You fear the thing, but cannot come up with any reason as to why.

"It's different, it's new, it must be bad"


If folks had thought like you 200 or even 100 years ago, we'd not have many modern foods or cures for diseases, there would be many fewer people in the world (many would have died from diseases or starvation).

The Roundup resistance gene is very well established in numerous crops in the United States. Transferring this gene to other plants is a relatively straight-forward exercise. Genetic analyses have consistently shown that the grains produced by plants with this gene addition otherwise identical to grains from unmodified plants.

Pesticide resistance modifications are a very good thing - they increase yields and significantly reduce the number of chemicals used to protect crops.

Unless you are extremely careful about what you buy, you probably eat plants with Roundup Ready genes on a regular basis.

Dazed.. I know where you are coming from, and in fact, it's amusing and entertaining to read similar "horror stories" in farm magazines in the 1950's when artificial insemination was first introduced. Among other "problems" forecast was that calves which resulted from AI (especially after they perfected the method of freezing semen) would give "frozen milk".

BUT... as a farmer, I'm not all that comfortable with the genetic modification of our food crops. They *may* be safe... the truth is... we don't *know* that for sure.

And we *won't* know it for at least a generation. There have been some adverse reactions in some animal studies with some RR foodstuffs; there just haven't been enough studies proving the complete safety to be sure yet.

And your historical "example" may not be the best... maybe we should have had more people thinking "it's new, maybe we'll wait awhile before using... say... Thalidomide to help pregnant women calm down and sleep".

Given our current knowledge, it's likely that RR plants aren't going to pose a danger to humans. But our current knowledge is possibly not complete.

I personally don't want my kids and grandkids to be the guinea pigs who prove that "whoops! We may not have been right about that stuff being safe after all".

As far as safety for consumption goes, our knowledge actually is reasonably complete. It is no great stretch to compare the genome of the food product produced by a genetically modified crop to that of an unmodified crop. In most cases for food crops, the transgenic DNA is not passed on to the next generation, so the harvested product actually is identical to that produced from conventionally selected varieties.

It is not as if GM food products are a black box and we don't know what is inside. Organisms only produce the materials they are genetically encoded to produce, so if the genomes come out a match (or at least match within the spectrum of variability present in the conventional crop), the materials produced will be the same as those produced by a conventional crop.

When you consider risks from GM crops, health concerns are easily assessed and managed; it is the environmental risks that are more difficult to figure out. However, as time has gone on and the US has approached 50% usage of GM crops for corn, cotton, and soybeans, experience has shown that the competetive advantage imparted by most GM traits in a managed field does not usually impart a competetive advantage in the wild. As a result, the environmental horror stories have not materialized either.

FWIW, the lysine errors were produced in a GM bovine growth hormone, not GM crops. The two things are very different; different methods, very different risk profiles.

One example?

1996. Genetically modified tomato called "FlavrSavr" is pulled from the market only a year after its introduction after studies indicate a problem with low nutritional value and evidence that pathogenic bacteria in human intestines could become antibiotic resistant from the tomato.

Do some research on it. Just because our "best current science" tells us one thing, certainly does not mean it's actually true. And science is the hand the feeds me.

Why do we not hear more? Money talks. Like it or not; believe it or not... It's easy for a company with plenty of $$$ to suppress things.

1996. Genetically modified tomato called "FlavrSavr" is pulled from the market only a year after its introduction after studies indicate a problem with low nutritional value and evidence that pathogenic bacteria in human intestines could become antibiotic resistant from the tomato.

According to Genetically Modified Foods: Safety Aspects - Engel, Karl-Heinz et al, which has a table of compared nutritional values for the trangenic vs. conventional tomatos, the nutritive values were all in the same range, except for a small anomaly in Vitamin A, which was accounted for by the fact that the Flavr Savr tomato was designed to be harvested earlier (part of what gave it a longer shelf life).

Although the concern about gene flow of the antibiotic gene to bacteria was a common criticism of the Flavr Savr, there is no evidence that this happened. Bacteria may sometimes incorporate plasmids, picking up foreign DNA in the process. The thought was that, since Flavr Savr used a gene that conferred resistance to kanamycin, bacteria might pick up that gene and become resistant to kanamycin as well. This was not reproduced in any studies and presumably did not happen in the wild, although kanamycin is a rarely used antibiotic, so it might not have been apparent.

However, the use of the kanamycin resistance gene in Flavr Savr had nothing to do with antibacterial qualities in the tomato. It turns out it was just a convenient gene to use as a genetic marker, so that they could sort modified from unmodified plants. Calgene (the company that produced the Flavr Savr) intended to change that gene as a result of the theoretical risk, but before the Flavr Savr took off, a cheaper, conventionally selected tomato with the same shelf-life came to market and made the Flavr Savr economically non-viable.

It is also worth pointing out that this was in 1996, the early days of genetic engineering and there have been quantum leaps in knowledge since then.

Genetically Modified Foods:
Are They a Risk to Human/Animal Health?
By Arpad Pusztai



Information is scarce about health hazards, such as toxicity in genetically modified (GM) crops.



Scarcity of safety tests

How can the public make informed decisions about genetically modified (GM) foods when there is so little information about its safety? The lack of data is due to a number of reasons, including:
It's more difficult to evaluate the safety of crop-derived foods than individual chemical, drug, or food additives. Crop foods are more complex and their composition varies according to differences in growth and agronomic conditions.
Publications on GM food toxicity are scarce. An article in Science magazine said it all: "Health Risks of Genetically Modified Foods: Many Opinions but Few Data".

1 In fact, no peer-reviewed publications of clinical studies on the human health effects of GM food exist. Even animal studies are few and far between.
The preferred approach of the industry has been to use compositional comparisons between GM and non-GM crops. When they are not significantly different the two are regarded as "substantially equivalent", and therefore the GM food crop is regarded as safe as its conventional counterpart. This ensures that GM crops can be patented without animal testing. However, substantial equivalence is an unscientific concept that has never been properly defined and there are no legally binding rules on how to establish it.

2 GM foods may cause bacteria to become resistant to antibiotics.

They can also produce allergies.

When food-crops are genetically modified, ("genetically modified" food is a misnomer!) one or more genes are incorporated into the crop's genome using a vector containing several other genes, including as a minimum, viral promoters, transcription terminators, antibiotic resistance marker genes and reporter genes. Data on the safety of these are scarce even though they can affect the safety of the GM crop. For example:
DNA does not always fully break down in the alimentary tract.3,4 Gut bacteria can take up genes and GM plasmids5 and this opens up the possibility of the spread of antibiotic resistance.
Insertion of genes into the genome can also result in unintended effects, which need to be reduced/eliminated by selection, since some of the ways the inserted genes express themselves in the host or the way they affect the functioning of the crop's own genes are unpredictable. This may lead to the development of unknown toxic/allergenic components, which we cannot analyze for and seriously limiting the selection criteria.

Current testing methods need radical improvements.

Currently, toxicity in food is tested by chemical analysis of macro/micro nutrients and known toxins. To rely solely on this method is at best inadequate and, at worst, dangerous. Better diagnostic methods are needed, such as mRNA fingerprinting, proteomics and secondary metabolite profiling.6 However, consuming even minor constituents with high biological activity may have major effects on the gut and body's metabolism, which can only be revealed from animal studies. Thus novel toxicological/nutritional methods are urgently needed to screen for harmful consequences on human/animal health and to pinpoint these before allowing a GM crop into the food chain.7
Safety tests on commercial GM crops

GM tomatoes: The first and only safety evaluation of a GM crop, the FLAVR SAVRTM tomato, was commissioned by Calgene, as required by the FDA. This GM tomato was produced by inserting kanr genes into a tomato by an 'antisense' GM method. The test has not been peer-reviewed or published but is on the internet.8 The results claim there were no significant alterations in total protein, vitamins and mineral contents and in toxic glycoalkaloids.9 Therefore, the GM and parent tomatoes were deemed to be "substantially equivalent."

Some rats died within a few weeks after eating GM tomatoes.

In acute toxicity studies with male/female rats, which were tube-fed homogenized GM tomatoes, toxic effects were claimed to be absent. In addition, it was concluded that mean body and organ weights, weight gains, food consumption and clinical chemistry or blood parameters were not significantly different between GM-fed and control groups. However:
The unacceptably wide range of rat starting weights (±18% to ±23%) invalidated these findings.
No histology on the intestines was done even though stomach sections showed mild/moderate erosive/necrotic lesions in up to seven out of twenty female rats but none in the controls. However, these were considered to be of no importance, although in humans they could lead to life-endangering hemorrhage, particularly in the elderly who use aspirin to prevent thrombosis.
Seven out of forty rats on GM tomatoes died within two weeks for unstated reasons.
These studies were poorly designed and therefore the conclusion that FLAVR SAVRTM tomatoes were safe does not rest on good science, questioning the validity of the FDA's decision that no toxicological testing of other GM foods will in future be required.


Rats' ability to digest was decreased after eating GM corn.
GM maize: Two lines of Chardon LL herbicide-resistant GM maize expressing the gene of Phosphinothricin Acetyltransferase Enzyme (PAT-PROTEIN) before and after ensiling showed significant differences in fat and carbohydrate contents compared with non-GM maize and were therefore substantially different. Toxicity tests were only performed with the PAT-PROTEIN even though with this the unpredictable effects of the gene transfer or the vector or gene insertion could not be demonstrated or excluded. The design of these experiments was also flawed because:
The starting weight of the rats varied by more than ± 20% and individual feed intakes were not monitored.
Feed conversion efficiency on PAT-PROTEIN was significantly reduced.
Urine output increased and several clinical parameters were also different.
The weight and histology of the digestive tract (and pancreas) was not measured.
Thus, GM maize expressing PAT-PROTEIN may present unacceptable health risks.

Allergen content increased when soybeans were genetically modified.
compositional studies

GM soybeans: To make soybeans herbicide resistant, the gene of 5-enolpyruvylshikimate-3-phosphate synthase from Agrobacterium was used. Safety tests claim the GM variety to be "substantially equivalent" to conventional soybeans.10 The same was claimed for GTS (glyphosate-resistant soybeans) sprayed with this herbicide.11 However, several significant differences between the GM and control lines were recorded10 and the statistical method used was flawed because:
Instead of comparing the amounts of components in a large number of samples of each individual GTS with its appropriate parent line grown side-by-side and harvested at the same time, the authors compared samples from different locations and harvest times.
There were also differences in the contents of natural isoflavones (genistein, etc.) with potential importance for health.12
Additionally, the trypsin inhibitor (a major allergen) content was significantly increased in GTS.10
Because of this, and the large variability (± 10% or more), the lines could not be regarded as "substantially equivalent."

GM potatoes: There is only one peer-reviewed publication on GM potatoes that express the soybean glycinin gene.13 However, the expression level was very low and no improvements in the protein content or amino acid profile were obtained.




The toxin level of GM cotton is unpredictable.


GM rice: The kind that expresses soybean glycinin gene (40-50 mg glycinin/g protein) has been developed14 and is claimed to contain 20% more protein. However, the increased protein content was probably due to a decrease in moisture rather than true increase in protein putting a question mark over the significance of this GM crop.

GM cotton: Several lines of GM cotton plants have been developed using a gene from Bacillus thuringiensis subsp. kurstaki providing increased protection against major lepidopteran pests. The lines were claimed to be "substantially equivalent" to parent lines15 in levels of macronutrients and gossypol, cyclopropenoid fatty acids and aflatoxin levels were less than those in conventional seeds. However, because of the use of inappropriate statistics it is questionable whether the GM and non-GM lines were truly equivalent, particularly as environmental stresses could have unpredictable effects on antinutrient/toxin levels.16

Nutritional/toxicological studies

Herbicide-resistant soybean: Studies have been conducted on the feeding value17 and possible toxicity18 for rats, broiler chickens, catfish and dairy cows of two GM lines of glyphosate-resistant soybean (GTS). The growth, feed conversion efficiency, catfish fillet composition, broiler breast muscle and fat pad weights and milk production, rumen fermentation and digestibilities in cows were claimed to be similar for GTS and non-GTS. However:
These experiments were poorly designed since the high dietary protein concentration and the low inclusion level of GTS could have masked any GM effect.
No individual feed intakes, body or organ weights were given and no histology was performed, except some qualitative microscopy on the pancreas.
The feeding value of the two GTS lines was not substantially equivalent either because the rats grew significantly better on one of the GTS lines than on the other.
The experiment with broiler chicken was a commercial and not a scientific study.
The catfish experiment showed again that the feeding value of one of the GTS lines was superior to the other.
Milk production and performance of lactating cows also showed significant differences between cows fed GM and non-GM feeds.
Moreover, testing of the safety of 5-enolpyruvylshikimate-3-phosphate synthase which renders soybeans glyphosate-resistant18 was irrelevant because in the gavage studies an E. coli recombinant and not the GTS product was used. Their effects could be different as the differences in post-translational modification could have impaired their stability to gut proteolysis.
Thus, the claim that the feeding value of GTS and non-GTS lines was substantially equivalent is at best premature.

Rats had meager weight gain when fed GM soybeans.

In a separate study19 it was claimed that rats and mice which were fed 30% toasted GTS or non-GTS in their diet had no significant differences in nutritional performance, organ weights, histopathology and production of IgE and IgG antibodies. However, under the unphysiological -- basically, starvation -- conditions of these experiments when, instead of the normal daily growth of 5-8 g per day, the rats grew less than 0.3 g and mice not at all, no valid conclusions could be drawn.
GM corn: One broiler chicken feeding study with rations containing transgenic Event 176 derived Bt corn (Novartis) has been published.20 However, the results of this trial are more relevant to commercial than academic scientific studies.


GM peas seem to have no harmful effects on animals but that doesn't mean they are safe for humans.
GM peas: The nutritional value of diets containing GM peas expressing bean alpha-amylase inhibitor when fed to rats for 10 days at two different (30% or 65%) dietary inclusions, was shown to be similar to that of parent-line peas.21
Even at 65% level the difference was small mainly because the alpha-amylase inhibitor expressed in the peas was quickly digested in the rat gut and its antinutritive effect abolished. Unfortunately no gut histology was done or lymphocyte responsiveness measured.
Although some organ weights, mainly the caecum and pancreas were different, those of others were remarkably similar suggesting that GM peas may be used in the diets of farm animals at low/moderate levels if their progress was carefully monitored.
However, to establish its safety for humans a more rigorous specific risk assessment will have to be carried out with several GM lines. This should include:

An initial nutritional/toxicological testing on laboratory animals
If no harmful effects are then detected, it should be followed by clinical, double-blind, placebo-type tests with human volunteers, keeping in mind that any possible harmful effects would be particularly serious with the young, old, and disabled.
A protocol for such testing was given at the OECD conference in Edinburgh, February 2000 and subsequently published.22

Toxins were found in mice after eating GM potatoes.

GM potatoes: In a short feeding study to establish the safety of GM potatoes expressing the soybean glycinin gene, rats were daily force-fed with 2 g of GM or control potatoes/kg body weight.23 Although no differences in growth, feed intake, blood cell count and composition and organ weights between the groups was found, the potato intake of the animals was too low and unclear, whether the potatoes were raw or boiled.

Feeding mice with potatoes transformed with a Bacillus thuringiensis var. kurstaki Cry1 toxin gene or the toxin itself was shown24 to have caused villus epithelial cell hypertrophy and multinucleation, disrupted microvilli, mitochondrial degeneration, increased numbers of lysosomes and autophagic vacuoles and activation of crypt Paneth cells. The results showed that despite claims to the contrary, CryI toxin was stable in the mouse gut and therefore GM crops expressing it need to be subjected to "thorough tests...to avoid the risks before marketing.24
When the health risks of GM potatoes were revealed in some studies, a debate ensued.


In another study, young, growing rats were pair-fed on iso-proteinic and iso-caloric balanced diets containing raw or boiled non-GM potatoes and GM potatoes with the snowdrop (Galanthus nivalis) bulb lectin (GNA) gene.25 The results showed that the mucosal thickness of the stomach and the crypt length of the intestines of rats fed GM potatoes was significantly increased. Most of these effects were due to the insertion of the construct and not to GNA which had been been pre-selected as a non-mitotic lectin unable to induce hyperplastic intestinal growth26 and epithelial T lymphocyte infiltration. Although there is controversy about the tests, most of the adverse comments on this Lancet paper were personal, non-peer reviewed opinions and, as such, of limited scientific value. The findings, on the other hand, were published in a peer-reviewed publication25 and the criticism replied to.7 The work, however, has not been repeated nor results contradicted and it is therefore imperative that the effects on the gut structure and metabolism of all other GM crops developed using similar techniques and genetic vectors should be thoroughly investigated before their release into the food chain.

GM tomatoes: This study with a GM tomato expressing B. thuringiensis toxin CRYIA(b) gene was published in a book and not in a peer-reviewed journal. However, its importance was underlined by the immunocytochemical demonstration of in vitro binding of Bt toxin to the caecum/colon from humans and rhesus monkeys.27 Although in vivo the Bt toxin was not bound by the rat gut, this was possibly due to the authors' use of recombinant Bt toxin.
Allergies are a major concern with GM food, especially if ingredients are not labeled in packaged food.
Allergenicity studies

One of the major health concerns with GM food is its potential to increase allergies and anaphylaxis in humans eating unlabeled GM foodstuffs.
When the gene is from a crop of known allergenicity, it is easy to establish whether the GM food is allergenic using in vitro tests, such as RAST or immunoblotting, with sera from individuals sensitised to the original crop. This was demonstrated in GM soybeans expressing the brasil nut 2 S protein28 or in GM potatoes expressing cod protein genes.29
It is also relatively easy to assess whether genetic engineering affected the potency of endogenous allergens.30 Some farm workers exposed to B. thuringiensis pesticide were shown to have developed skin sensitization and IgE antibodies to the Bt spore extract. With their sera it may now therefore be possible to test for the allergenic potential of GM crops expressing Bt toxin.31 It is all the more important because Bt toxin Cry1Ac has recently been shown to be a potent oral/nasal antigen and adjuvant.32



There are no reliable ways to test GM foods for allergies.


Assessment of the allergenicity of a GM foodcrop, however, is difficult when the gene is transferred from a source not eaten before or with unknown allergenicity or on gene transfer/insertion a new allergen or adjuvant is developed or the expression of a minor allergen is increased. Unfortunately, while there are good animal models for nutritional/toxicological testing, no such models exist for allergenicity testing.
Presently only indirect and rather scientifically unsound methods, such as finding SHORT sequence homologies (at least 8 contiguous amino acids) to any of the about 200 known allergens, are used for the assessment of allergenicity.
The decision-tree type of indirect approach based on factors (such as size and stability) of the transgenically expressed protein33 is even more unsound, particularly as its stability to gut proteolysis is assessed by an in vitro (simulated) testing34 instead of in vivo (human/animal) testing and this is fundamentally wrong. The concept that most allergens are abundant proteins is also misleading because for example Gad c 1, the major allergen in codfish, is not a predominant protein.29
However, when the gene responsible for the allergenicity is known, such as the gene of the alpha-amylase/trypsin inhibitors/allergens in rice, cloning and sequencing opens the way for reducing their level by antisense RNA strategy.35
Thus, in the absence of reliable methods for allergenicity testing, it is at present impossible to definitely establish whether a new GM crop is allergenic or not before its release into the human/animal food/feed chain.

We need more and better testing methods before making GM foods available for human consumption.
In conclusion

One has to agree with the piece in Science1 that there are many opinions but scarce data on the potential health risks of GM food crops, even though these should have been tested for and eliminated before their introduction. Our present data base is woefully inadequate. Moreover, the scientific quality of what has been published is, in most instances not up to expected standards. If, as claimed, our future is dependent on the success of the promise of genetic modification delivering wholesome, plentiful, more nutritious and safe GM foods, the inescapable conclusion of this review is that the present crude method of genetic modification has so far not delivered these benefits and the promise of a superior second generation is still in the future. Although it is argued by some that small differences between GM and non-GM crops have little biological meaning, it is clear that most GM and parental line crops fall short of the definition of "substantial equivalence." In any case, this crude, poorly defined and unscientific concept outlived its possible previous usefulness and we need novel methods and concepts to probe into the compositional, nutritional/toxicological and metabolic differences between GM and conventional crops and into the safety of the genetic techniques used in developing GM crops if we want to put this technology on a proper scientific foundation and allay the fears of the general public. We need more science, not less.6,7

Organic farmers here. Just speaking from experience (ours and those we know).

Farmer in a town near us had GM corn in the bin, killed the rats in a short time (our rats still live on!).

A number of cases of Monsanto taking farmers to court for planting their GM corn but not purchasing the seed from them.
Problem lies in the wind . . . GM corn can turn other unmodified corn seed into GM seed. If my neighbors' GM corn field infects my organic corn field, I'm screwed - Monsanto can sue ME. AND I lose my organic status.

In addition to the health problems that GM foods may or may not cause, I believe GM seed is bad:

- because it will eventually create a monopoly for Monsanto,
slowly at first, but as ALL the corn seed is eventually infected,
the farmer buys ONLY from them.

- because the FLAVOR of GM products SUCK! Eat an organic
garden tomato or ear of corn right along side a GM ear of
corn.

- because roundup ready seed can (and most likely will) cause
the soil to stop producing. In organic, we rotate crops - never
corn on a field that had corn last year. We replenish the soil
periodically with alfalfa or field peas or something with good
nutrients. Now take a chemical farmer - especially with the
no-til practice that has become popular. A lot of the big
corporate farms (at least around here) plant corn on corn,
spray like crazy, using no-til. Their ground looks like cement,
half of them collect insurance because of crop failure. Those
fields have huge patches of barren ground. I just can't see
using GM seed on already chemically saturated ground.
How can we be eating anything but the chemical?

- because IF Monsanto eventually has a monopoly on ALL corn
seed because it's all been GM'd, you can darn well bet there'll
be a seed shortage for some reason or other, which means
higher cost, and probably even the govt stepping in and
dictating who will get the corn seed that year.

My bet is 10 years, and we'll be farming for the govt like Russia did (was it in the 70's??), and we'll be seeing a food shortage in the US.

Very different...yet from the "same" company... The same Monsanto who witheld disclosure of their Lysine error - even when they knew the health risks would be great! We are to simply trust this same corporation with any of their creations?

Well, there are a lot of reasons why the information may have been slow to come to light, not the least of which is contradictory testing. I don't know if they intentionally withheld negative information or not.

But either way, we should not trust any claim of any company without some skepticism. In the case of GM crops, there has been a great deal of study and I feel comfortable with the results. I know a lot less about animal hormone engineering, so I'm not going to speculate about what was going on there.

We are what we eat. Until recently - what we ate was grown in a natural way - with perhaps "splicing" variables of the same species for a heartier crop... What Monsanto is doing to our food is barbaric ! They are adding genes from completely different species to our food, they are inventing modified antibodies and bacteria and splicing them into our vegetables. They are adding pesticides to the genetic structure of our vegetables...They are currently investigating whether or not GM food is the cause the the increase in peanut allergies in the US. We are what we eat - and we have no idea what we are eating and what will become of us for eating it.

That all sounds quite alarmist, but so far none of these things have shown to have negative consequences in the forms that are eventually selected for use outside the lab. In fact, all of these things have been quite beneficial in terms of crop resilience and yield, which will be important in a world facing increasing environmental stresses.

I haven't heard anything about a peanut allergy link. Do you have a reference?

No one else wants their GM crops. Not Europe, not South America, Not Japan, etc... We - the people of the USA were not even given a choice.:rolleyes:
I'm sick of modified everything! I'm sick of seeing so many sick people in this country while people like you act as cheerleaders for these organizations and their unnatural creations...

Your implication there is that GM crops cause sickness, but there is not any conclusive proof of this, nor even any strongly correlated data that I am aware of.

And then there's this article......As you read through the numerous concerns about the health risks of GM food - remember that with natural food - we have none of these concerns... The fact that these foods are not natural and there are many concerns over the long term safety of these products - concerns me. It should concern everyone.
http://www.actionbioscience.org/biotech/pusztai.html

The term 'natural' is meaningless. Arsenic and lead are natural, but you wouldn't want to eat them. Changes to food crops should concern us, but those concerns should be grounded in reality, not rampant speculation.

article said:
[FONT=Verdana,Arial]In fact, no peer-reviewed publications of clinical studies on the human health effects of GM food exist. Even animal studies are few and far between.


Well, simply enough, people don't usually do clinical studies on food products. There have been many genomic comparisons, which serve the same purpose when it comes to risk assessment. There are also all kinds of allergenic assessments that have been done. Nothing is perfect, of course, but the changes made in genetically manipulated crops are usually very small, with predictable expressions. After all, if they are not predictable, they are not desireable.

article said:
[FONT=Verdana,Arial]Insertion of genes into the genome can also result in unintended effects, which need to be reduced/eliminated by selection, since some of the ways the inserted genes express themselves in the host or the way they affect the functioning of the crop's own genes are unpredictable. This may lead to the development of unknown toxic/allergenic components, which we cannot analyze for and seriously limiting the selection criteria.


Unintended effects are possible and even common, but not in GMOs that make it outside the lab. Again, unpredictability is not desireable in an engineered crop. So, it is always possible to create unpredictable, negative effects, but how great is the risk? Twenty years of experience seem to indicate that unpredictable effects are rare, perhaps non-existent in marketed products.

Some rats died within a few weeks after eating GM tomatoes.
[/FONT]

This appears to be an exaggeration of a quote from one of the engineers of the Flavr Savr Tomato (which is discussed a few posts above) who indicated that some rats did not want to eat the tomatos in tests. The theory about why the rats did not want to eat the tomatoes was simple enough: this tomato was designed to be harvested early - before fully ripe. Some rats were force-fed the tomatoes, which could have had a negative effect on them. Regardless, there is nothing I can find in the study data about the rats dying.

article said:
[FONT=Verdana,Arial]Rats' ability to digest was decreased after eating GM corn.

[/FONT]
[FONT=Verdana,Arial]
This quote is a bit misleading. The rats were apparently not as efficient at digesting Chardon maise, not compromized in general digestion.

That said, if there is a case in here that I'd say warrants more investigation, this is the one. Chardon maise is intended only for use as animal feed, so its designers may not have been as stringent. There seems to be some merit to the concerns about its protein composition.

article said:
[/FONT][FONT=Verdana,Arial]Allergen content increased when soybeans were genetically modified.


[/FONT]
[FONT=Verdana,Arial]This [/FONT][FONT=Verdana,Arial] [/FONT][FONT=Verdana,Arial]claim and the claims of different nutritional value do not appear to be borne out in reality. [/FONT]Fully 50% of US soybean crops are glyphosate resistant varieties and they constantly assay at the same nutritional values and do not appear more allergenic than other crops.

And it goes on, but its late and I'm out of steam.

This probably won't convince anyone who feels GM crops are bad news, but there really is a lot of hysteria out there. There are good reasons to be a skeptic and learn about this stuff and it is good to be cautious with food products, conventially selected or otherwise. But, learning about any subject from biased sites on the Internet is not a great way to get a clear and reasoned knowledge of the subject.

Animals won't eat GM corn unless they are starving - and sometimes not even then. Wild birds and squirrels won't eat it. Cows won't eat it. They are more intelligent than humans.

There are numerous tests in Britain and Russia where GM potatoes killed test animals.

This probably won't convince anyone who feels GM crops are bad news, but there really is a lot of hysteria out there.

And there is a lot of denial out there.! Especially from those who stand to profit from GM production, sales and stock.

There has been enough uncovered about Monsanto to make even the cheeriest cheerleader raise an eyebrow. The bottom line is - you, the scientists and the public simply DO NOT KNOW THE HEALTH RISKS involved with this mad gene splicing of our food. You don't know because Monsanto doesn't even know...:shr:

We have seen Monsanto aggressively try to hush their critics. If they were so confident in the safety of their product - why be so quick to intimidate those who ask serious safety questions? Why haven't Monsanto's scientists been able to enlist support from biologists from the countries who refuse their product? Could it be that the science is too risky and this fact is not lost on countries not bound to our lax FDA approval?

With all of the illness currently attacking our population - I can't help but be suspicious of any and all modifications to our food and water sources. Colon cancer rates have gone through the roof over the past 10 years. That leads me to believe that something has been introduced to our food that is causing this cancer manifestation. Esophageal cancer rates have also exploded over the past 10 years...These two cancers are manifesting in areas of digestion. Something in our food is causing it. GM foods could very well be the culprit! But we don't know - neither do you.

These cancers, allergies, autoimmune disorders were never at rates we see now. Prior to GM foods, Fluoridated water, Trans fats and the increasing heavy dosed childhood vaccine programs - we just weren't so sick. If we have to remove each of these possibilities from our diet to see which ones could be influencing our illness rates - then let's do it! - then we could re-introduce the ones that did not affect illness rates... Transfats have only recently been removed from much of our foods - but still remain in many processed foods. That's a start. Some cities are reversing their policies to add fluoridate to their water. This is a great start and hopefully some studies will be performed to determine if cancer and other illness rates decline. This is how it has to be done. We, the public, have become the lab rats in this awful experiment. We know something has been able to produce illness in us - now it's time to determine what it is. We can only do this by the process of elimination.

It's just that important.

dang, I missed the fun

I had hoped be a bit more involved in this discussion, but I was away...and now I'm too tired to think. =)

However, regarding animals refusing to eat GM food...I know there have been studies, and somehow, even though in labs, to people, the foods are "identical," the animals are somehow able to determine which is GM, and generally avoid it. If true, then it really begs the question - how does an animal do better at determining which is GM than our science? (And...this will probably never be answered...but WHY do they choose to avoid it? Because it's not what they're used to? It doesn't smell like their normal stuff? They figure it's better and they should let humans consume it? Those are the types of things I'd want answered before I welcome it onto my plate.)

Some anecdotal stuff is at http://www.i-sis.org.uk/AAGMF.php ...not sure if there's been a scientific study that was done by a NON Bio-Company and NON Anti-Bio-Organization that would be a bit along the lines of "OK, I can trust this study."

Given a choice, my guess would be that over 90% of the world populace would prefer "what nature provides" over "what a Bio-Company engineered."
With that said, with most of the current GM foods, I'd bet that over 90% of the populace, if given the choice, would choose GM food over nothing at all.

There have not been many studies where animals refused to eat GM foods. There is one classic, which is the Flavr Savr mentioned above, which they eventually figured out was due to the early harvest of the tomatoes (rats also won't eat conventionally selected tomatoes when they are not yet ripe).

The problem is, this stuff gets repeated over and over again on the Internet, without context or understanding and then people get hysterical over it. Almost every criticism of GM crops you read is packed with this nonsense.

That doesn't mean that GM crops are without risk, or that all studies are well designed and without bias, or that companies don't ever cross the line and do unethical things to make profits. These things happen in all human endeavors and we should all have a healthy does of skepticism. But, when skepticism is not based on logic, it turns into paranoia.

We should debate these issues with accurate information and many of the anti-GM points that are continuously recycled are without merit and/or out of date.

this is the CURRENT single issue that will define the struggle of humanity against traitors of humankind

a line in the sand must be drawn

genetic engineering is a crime.
when animals are offered a choice between genetically modified food and normal food they always eat the natural food. if they are however made to eat gm food they get cancers, internal bleeding, brain tumors, their own dna contamination meaning their offspring will be fawked. the same is true for humans. a dna strain gets into your body and starts acting as a genetic parasite. your body starts producing pesticides. DNA resequencing of food is crazy.

usa, canada, india, argentina are already contamined with gm.

do your utmost to not let it spread and have the courage to stop it where it's already happening.

we and our future generations are under attack from greedy individuals who are willing to risk genetic damage to humans by trying to corner the world food market.

our extinction could follow

You are repeating what has already been said in this thread numerous times. If you make specific claims, I can probably refute them with available data. If you just keep repeating the same broad, incorrect claims over and over again, all I can do is remind you that there is not data to support those claims, unless you intentionally misinterpret it.

Saying over and over that GM crops are the plague of the world, animals won't eat them, and they will destroy us all doesn't make any of these statements true. If you have actual data of any kind, with references to research, or at least news events that show correlation, I would love to see them.
