Most common Shiga-Toxin E.coli serotypes → mauve
Other Enterobacteriacae → colourless, blue or inhibited
Gram positive bacteria → inhibited

An increasing and worrisome number of studies have lately shown that, non-O157 Shiga Toxin producing E. coli (STEC) have been responsible for foodborne poisoning outbreaks. The CDC has also reported warnings about this potental risk. Therefore, several regulatory authorites urge worldwide food industry to implement measures to control the absence of such organisms in their producton.
In many cases, laboratories have limited their search for pathogenic E. coli to the common O157 serotype. This is due, among other reasons, to the fact that were no available selectve culture media for non-O157 E. coli. CHROMagar™ STEC is designed to fll this gap.
