History

Controversy

Niigata Minamata disease

The company is known for causing the second outbreak of Minamata disease (a type of severe mercury poisoning) in Kanose, currently part of Aga-machi, Niigata Prefecture, through the release of organomercury compounds into the Agano River.

Tryptophan contamination

In the late 1980s Showa Denko K.K. decided to change the method it used to produce tryptophan, from fermentation to the genetic engineering of bacteria. Bacteria were engineered to express certain enzymes at much higher levels than normal, and to express other enzymes not normally present in the original bacteria. Because the company had been producing tryptophan for many years via fermentation methods, when production was switched to genetic engineering, no safety testing was deemed necessary. The new tryptophan was placed on the market, and within a few months it caused the deaths of 37 people and caused 1500 more to be permanently disabled. Unfortunately the new tryptophan product was discovered to contain trace amounts of a toxic dimerisation tryptophan product which caused Eosinophilia-myalgia syndrome.
