The Showa Denko Tryptophan disasterNew evidence indicates that genetic engineering |
Brief summaryAn extremely poisonous substance in a food supplement killed 37 died and 1500 contracted a chronic severely painful and incapacitating disease about 1990. At that time, the biotech industry maintained that decreased filtration of the broth caused the accident, but our conclusion, based on recently discovered evidence, is that, with great certainty, a metabolic disturbance, caused by genetic engineering, was the reason for the appearance of the deadly poison. As this disaster demonstrates that genetic engineering may give rise to very dangerous unexpected substances, difficult to detect, the present method used for assessing the safety of all genetically engineered foods must be abandoned and all foods on the market must be withdrawn. This is because the present GE food safety testing procedures are far too insensitive to detect such unexpected dangerous poisons that may appear through genetic engineering. Therefore, it is only a matter of time before another posioning disaster occurs. |
Executive summaryIn 1989, a disastrous epidemic broke out in the US that caused 37 deaths and disabled 1.500 permanently in a disease called the "Eosinophilia-Myalgia-Syndrome" (EMS). It was caused by some extremely poisonous substance in the food supplement tryptophan, which had been produced by genetically engineered bacteria at the Japanese company Showa Denko. The biotech industry maintained that the disaster was not caused by genetic engineering but by an "impurity" due to reduced filtering of the product. But recently it has been discovered that hundreds of cases contracted EMS before the filtering was decreased. We have made a careful analysis of the facts to find out if there was any plausible other reason for the appearance of the deadly poison than genetic engineering. Bacterial fermentation, the method used for producing tryptophan, had an excellent safety record since over 60 years before genetically manipulated bacteria were used. Therefore it is extremely unlikely that the fermentation process produced the poisonous by-product. On the other hand, molecular biologists predicted decades ago that genetic engineering may cause changes that induce the appearance of unexpected and potentially harmful substances. And this prediction has been confirmed in a number of cases. Moreover, not one, as commonly is the case, but four different genes had been inserted, and experience has shown that this increases the risk for unpredictable consequences. Our conclusion is that genetic engineering caused the disaster with great certainty. If the generally used method for safety assessment of genetically engineered foods had been used, this deadly tryptophan would have passed as a safe product. This safety assessment is clearly insufficient because is not designed to reveal unexpected poisons. All genetically engineered foods on the market have been tested with this method and are therefore unsafe. They must therefore all be withdrawn. It is only a matter of time before another disaster occurs, because genetic engineering can generate unpredictable harmful substances. Showa Denko was the Harrisburg of gene technology. Must we have a Chernobyl before the use of GM foods is stopped? |
37 persons died and 1.500 were permanently disabled in a disease called Eosinophilia-Myalgia-syndrome (EMS) caused by some extremely poisonous substance present in a tryptophan food supplement, which was produced by genetically engineered bacteria at the Japanese firm Showa Denko (1).
The american attorney William Crist has recently made a very thorough investigation which has helped bring increased clarity to the question whether genetic engineering was the cause of the appearance of this deadly toxin (2).
Therefore, as all other elements in the production method have been cleared beyond reasonable doubt, we can conclude with great certainty that the bacteria themselves caused the emergence of the poison and not some fancied other source in the production process as implied by the biotech corporations.
Considering the above points, including especially the impeccable safety record of bacterial fermentation and the theoretically predicted and experimentally confirmed risk for GE-induced metabolic disturbances generating unpredictable poisons, in this case enhanced by multiple gene insertions, it can be concluded with very great certainty that it was genetic engineering and nothing else that caused the appearance of the poison.
When the kind of poison was found in the investigation of the disaster, that could be expected to be produced due to disturbed metabolic control, scientists began to express great concerns about genetic engineering.
Soon after the report saying that the poison in the tryptophan pills was similar to the amino acid tryptophan, a very confusing report appeared. This new report indicated, that even tryptophan itself could produce EMS-like symptoms. There are strong reasons to suspect that this report was "fabricated evidence".
This is because no other study has reported that tryptophan is harmful. Tryptophan is a natural substance, an amino acid that is part of the normal biochemistry of the body and such. Therefore, if tryptophan itself had been poisonous, EMS would have been a major disease of mankind. Actually, the US food and drug agency, FDA, now allows tryptophan to be used even in baby food.
Still, at that time, the "toxic tryptopan" report was taken by FDA as a reason to consider other reasons than GE for the toxicity.
Just at the time of the accident, the Biotech corporations were about to launch GE foods. If EBT were proven to be the cause of EMS, it would be probable that GE was the reason for the disaster. They realized that this would make it psychologically impossible to sell GE foods on the market without very expensive (billion dollar) safety testing which would wreck the whole GE food project that just was about to be launched.
Facing this threat, it is very likely that the corporations "encouraged" the fabrication of "advocacy" research reports that confused the issue (this would not have been the first time science was misused to promote corporate interests, see "Dysfunctional science"). The report that natural tryptophan caused EMS-like symptoms in rats was an ideal and effective confusing factor that contributed to the conclusion that the issue could not be settled.
As FDA is the authority responsible for food safety, they should have done everything possible to find out if GE caused the accident, considering that GE foods were about to be launched for commercial production. They should have initated a careful investigation of the suspect itself, the Showa Denko bacteria. This would have made it possible to find out for sure whether the poison was made by the bacteria and whether genetic engineering was the cause. But this was not done. The bacteria were avaialable and Showa Denko offered to send them to FDA for investigation, but FDA showed no interest, according to a message to us from an American lawyer who assisted Showa Denko. Later they were destroyed by Showa Denko.
In stead, the absurd report about natural tryptophan causing EMS-like symptoms was taken very seriously by FDA as an important reason for concluding that it was not clear that genetic engineering was the cause.
This may sound amazing, but it is a well established fact that FDA was heavily biassed in favor of GE foods, to the extent that, when the GE foods were about to be launched, it ignored severe warnings from its own scientists about using GE foods, and suppressed evidence indicating harmful effects of genetically engineered food. This was found out in an investigation of FDA protocols made by the lawyer Steve Druker in a lawsuit against FDA (4).
This explains why FDA, in spite of compelling reasons to suspect that genetic engineering caused the disaster, apparently was completely uninterested in finding out the real truth, and accepted very weak and unlikely evidence as an excuse to drop the case.
No other scientifically tenable reason for the appearance of the deadly poison has been found, and the probability for a metabolic disturbance to occur due to genetic engineering was considerable, considering that four different genes had been inserted, causing an especially great degree of instability in the cellular regulation of the production of tryptophan.
This is furthermore supported by the fact that unexpected poisonous substances have been reported also in some other cases of genetic engineering. On the other hand, when natural bacteria have been used for producing tryptophan and many other substances at a massive scale, no harmful substance has appeared.
Therefore, we can conclude with great certainty that a metabolic disturbance, caused by genetic engineering, was the reason for the appearance of the deadly poison in the tryptophan-producing bacteria of Showa Denko.
Therefore, it is only a matter of time before another unexpected toxin appears in GE food, which in the worst case might harm millions of people before the connection is discovered, especially if, as is the case in the US and Canada, the GE foods are not labeled.
Consequently, all GE foods must be withdrawn from the market before another disaster occurs.
If, for some ethically unacceptable reason, this is not immediately done, at least the GE-foods must be immediately labelled so people have a chance to avoid them. Presently the only way to do so in countries, including the US, where they are not labeled, is to eat only certified organically grown food.
It will take several decades to develop sufficent knowledge about genetic engineering so as to know how it works (see "Incomplete knowledge about DNA"). Already now there exists enough knowledge about the effects of GE to be able to conclude that GE is not safe enough for developing any kind of organism and that its inherent nature is such that it can never be safe. Therefore the only reasonable and sound scientific conclusion is that it is a dangerous method, not to be used, if at all, other than under strictly contained laboratory conditions.
It is no doubt a matter of time only before genetic engineering will be forbidden, and mankind will be amazed how governments and international organs, including the FAO and Codex Alimentarius, could allow such a potentially disastrous method to be deployed in spite of very incomplete knowledge of DNA and the effects of gene manipulation on the cell as well as its health and environmental consequences.
The reckless dissemination of genetically engineered foods and other GMOs is nothing less than a great scandal made possible by political suppression of serious warning signals and disinformation from corrupt or incompetent scientists sponsored by irresponsible multinational corporations.
It is not a question whether, but when the next disaster occurs. considering the serious incompleteness of knowledge and the highly insufficient safety assessment metods.

Showa Denko was the "Harrisburg" of Genetic Engineering. We should not need a "Chernobyl" before it is banned, especially as no GE food and no other GE product provides any such benefit that it is justified to take any risk at all by using it. |

2. The report of William Crist regarding the Showa Denko catastrophe as presented in the book "Seeds of deception" by Jeffrey Smith. It is an excellent presenation of the GE food issue reveailing the governmental corruption and the deceptive behavior of biotch corporations in the process of establishing commercial approval of GE foods.
3. a)Tobacco plants were genetically engineered to produce the Gamma-linoleic acid, a popular food supplement. In stead the plant unexpectedly mainly produced the toxic octadecatetraenic acid. This substance does not exist in the natural tobacco plant. (Reddy SA, Thomas TL. Nature Biotechnology, vol 14, sid 639-642, May 1996)
b) When a yeast was manipulated for increased fermentation there was an unexpected production of a metabolite (methyl-glyoxal) in toxic and mutagenic concentrations. (Inose, T. Murata, K. Int. J. Food Science Tech. 30: 141-146, 1995).
4. FDA lawsuit
5. Excerpt from our Open Letter: "We, the undersigned scientists and physicians, demand that all genetically engineered (GE) foods be withdrawn from the market unless they have undergone rigorous safety assessment including long term testing on animals and humans." No GE food sold as human food has presently undergone such testing.
6. Inadequate safety assessment of GE foods.
7. An example of fatal substantial equivalence. Applying the Showa Denko case, we demonstrate how useless and insufficient the present safety assessment procedure is.
8. Professor Gilles-Eric Seralini pointed out serious weaknesses in the safety analysis of a GE Maize variety that was approved as harmless on the basis of substantial equivalence. More.
The "Harrisburg accident" occurred 1979 in a nuclear reactor in Harrisburg, PA, US, that came close to meltdown (also called the "Three mile Island accident"). It sparked the discussion of the safety of nuclear energy. But not until the Chernobyl catastrophe occured in 1986, the further usage of nuclear energy in the US and other countries was either stopped or plans were made to replace it with other solutions as soon as possible.
Before Harrisburg, experts sponsored by the US and other governments, fervently denied that the technology was unsafe. Still several independent experts had warned that nuclear energy reactors are unsafe. This situation is very similar to the denial today of GE risks by biotech sponsored scientists and the refusal of governements to listen to the well underpinned warnings of impartial experts including PSRAST.
This shows that it is unacceptable and dangerous that governmental bodies interfere with, and override technology assessments made by impartial scientists. They evidently don't have the competence, foresight, intelligence and sense of responsibility to be able to handle complex technological issues. Unfortunately corruption of government officials and politicians has contributed to suppression of truth.
This danger is especially great now that science has reached a level where it is capable of generating very powerful technologies that can destroy the Earth.
We have suggested the establishment of national and international councils of truly independent experts that have the ultimate, unrestricted power to decide for the country, or for the world, in issues regarding responsible and safe application of new technologies, see "A suggested procedure...". History has very clearly shown that there are very strong reasons to create such bodies whose decisions are imperative and cannot be overrun by any political or corporate influence.
