Guidelines for the examination of food samples during microbiological food safety testing recommend detection of the Enterobacteriaceae. In addition to coliforms, this group includes salmonellae and shigellae, which do not ferment lactose, and enterotoxigenic Escherichia coli. It also contains organisms, such as Klebsiella and Citrobacter, which are more resistant to heat than coliforms and are, therefore, better indicators of failure of processes that use minimal heat.
The difficulties of measuring the total Enterobacteriaceae content of food samples have been studied by Mossel3, who showed that the addition of glucose to an existing medium for the detection of coliforms improves the performance—as shown for Violet Red Bile Glucose Agar.
Violet Red Bile Glucose Agar has been developed to satisfy all of the below criteria of an approved media which complies with the recommendations of ISO:
