Colorex E.coli

Focus on E.coli 

Coliforms are viewed as indicators of contamination by organic, environmental or faecal material.

Contamination by faecal material from animals can be shown by the detection of Escherichia coli in the sample. E.coli can contaminate drinking water when the water treatment system is inadequate or during periods of very high rainfalls.

Monitoring of food and water production is essential. High contamination may lead to the suspension of the water supply and food recall by supermarkets.

Regulations concerning bathing water:

European directive from 1976: 2.000 Escherichia coli (E.coli) bacteria for 100 ml of water.

New directive in 2006 (effective in France in 2015): 500 E.coli per 100 ml.


Medium Performance 

1. 24 h detection.

2. Easy reading and interpretation: The general food and water standards limits are usually zero to single figure E.coli cfu per gram and thus it is important to detect and enumerate them accurately. With Colorex E.coli, colonies of E.coli develop with an intense blue colour - thus making detection and enumeration of this important hygiene indicator as simple as possible. 

3. Lighter Workload: Traditional E.coli detection methods are extremely tedious and labor-intensive, requiring experimental studies of many colonies.

4. Quality: Colorex media contain 5% more agar than other media on the market. This helps considerably with the application and streaking of the sample onto the plate.
