EC BROTH

Description

EC Broth is employed in elevated-temperature tests for distinguishing organisms of the total coliform group that also belong to the fecal coliform group. The fecal coliform test, using EC Medium, is applicable to investigations of drinking water, stream pollution, raw water sources, wastewater treatment systems, bathing waters, seawaters, and general water-quality monitoring. EC Medium is used in the MPN (Most Probable Number) test for fecal coliforms. The medium was originally described by Hajna and Perry. Fishbein and Surkiewicz used the EC confirmation test for recovery of E. coli from frozen foods and nut meats and reported that the test worked optimally when conducted at 45.5?C with incubation being limited to 24 hours. The procedure employing EC Medium provides information regarding the source of the coliform group (fecal or non-fecal) when used as a confirmatory test. EC Broth is recommended by American public Health Association (APHA) and AOAC International for detection of water, wastewater and foods.
