“The issues are twofold: (1) Tryptophan itself clearly is not the cause of EMS in that individuals who consumed product from companies other than Showa Denko did not develop EMS, and (2) The evidence points to Showa Denko product as the culprit and to the contaminants as the cause. But we still do not know which contaminant and therefore we cannot know whether the fermentation process employing the genetically altered bacterium was responsible. In retrospect, the essence of the matter comes down to a question of chemical purity and had the Showa Denko product been sufficiently pure the epidemic would not have occurred.”
