Anti-thiamine Activity in Hawaii Fish

Abstract
Various species of fish found in Hawaiian waters were analyzed for anti-thiamine activity. Twenty-one of the 30 species tested contained thiaminase. A thermostable anti-thiamine factor was also usually present in the fish that contained enzymatic activity. Although anti-thiamine activity was more prevalent in certain families of fish, there was no constant correlation between taxonomic classification or the feeding habits or habitat and the presence of anti-thiamine activity.
