E*Colite
The Charm E*Colite test is used to screen water, foods, and juices for coliform and Escherichia coli. This vial test format provides a positive or negative result in 24 hours for coliform and 24 to 28 hours for E. coli. It uses the same media of the EPA approved bag format test without risk of spillage or odors from grown cultures.
The E*Colite media enables the detection of a single coliform and/or E. coli bacteria in a 100 mL sample. Food samples such as milk and juice are diluted in water for testing. The E*Colite media is formulated to resuscitate and detect chlorine-stressed coliforms that may be found in drinking, bottled, and food/beverage waters.
Read results visually by examining the color. A negative sample is yellow. Coliform presence is indicated by a blue color, which is easy to see, especially in turbid or rust and heterotrophic bacteria-contaminated waters. Blue with fluorescence at 366 nm indicates the presence of E. coli.
