Technical Abstract: Shiga toxin-producing Escherichia coli (STEC) were isolated from different environments in three California counties. Expression of Shiga toxins was induced by nutrient depletion. Mass spectrometry was used to identify and quantitate the Shiga toxins present in the culture supernatants. These STEC produced Shiga toxins over a fifty-fold range.
