Chromogenic agar media for rapid detection of Enterobacteriaceae in food samples

Recently, chromogenic media were used for rapid detection of pathogenic agents isolated from different materials (food, water and stool). Results of the present study indicated that specific and rapid identification of Enterobactiriaceae isolates from 46 food samples (egg, dairy products, meat, salads and cooked rice) as compared to conventional methods of biochemical test and plating selective media consume times, are expensive , autoclaving, and less selective. Both media ECC Agar (HIMEDIA) and Salmonella differential agar (Raj Hans Medium, HIMEDIA) are powerful for screening isolates from food samples: Esherichia coli, Salmonella spp., Klebsiella pneumoniea.
