Focus on STEC E.coli |
|
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 potential risk:
“ Disease caused by Shiga toxin-producing Escherichia coli (STEC) ranges from self-limiting diarrhea to hemorrhagic colitis and hemolytic uremic syndrome (HUS). Serotype O157:H7, the most frequently implicated STEC causing hemorrhagic colitis and HUS, has been isolated from large foodborne outbreaks, as well as sporadic cases, in North America and abroad. However, 60 STEC serotypes have been implicated in diarrheal disease, and several non-O157:H7 serotypes have been implicated as the cause of foodborne outbreaks and HUS in the United States, Europe, and Australia. Studies from Canada, Europe, Argentina, and Australia suggest that non- O157:H7 STEC infections are as prevalent, or more so, than O157:H7 infection.”

Therefore, several regulatory authorities urge worldwide food industry to implement measures to control the absence of such organisms in their production.
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 there were no available selective culture media for non-O157 E.coli.
CHROMagar STEC is designed to fill this gap: detection, as mauve colonies, of not only the classical STEC O157, but also many other serotypes.
