Koliformas / E.coli

Peel Plate EC (E. coli and Coliform) tests use traditional EC media with color producing enzyme substrates and a 24 hour incubation. Coliforms produce easy to interpret red colonies that do not need additional confirmatory steps or difficult to interpret gas production. Most E. coli produce blue/purple colonies. The quantitative method is applicable for determination of total coliform, sum of coliform and E. coli, in dairy products at 32 °C incubation. The method will detect E. coli from coliform in ground beef, food, carcass rinses, environmental surface sponge and water samples at 35 °C incubation.
