Focus on E.coli and Coliforms
Coliforms, Enterobacteriacae able to ferment lactose (lactose positive Enterobacteriacae), are bacteria present not only in
human and warm blooded animals intestinal flora but also in the soil and water. Coliforms are proof of organic, environmental
or faecal contamination. Faecal contamination due to coliforms coming from animal waste, consists mainly of Escherichia coliand thermotolerant Klebsiella.
Strict regulations exist for E.coli/Coliform presence in water samples.
This can be explained by the importance of these germs in determining drinking water safety and process efficiency of
treatment, storage and distribution.
