As it was a patented process, they were the only one doing it. When they were processing the fermentation product, to extract the tryptophan, they also used a non-standard and inferior purification step. They thought they were going to make a huge profit that way, eh? Anyway, the impure tryptophan contained a never-before-identified contaminant. It was this unique string of events that produced the contaminant, and the company's greed that released it to the marketplace. You can feel safe that they aren't letting that ever happen again. It just won't happen again.
