Coliform & E.coli

Coliform bacteria are commonly found in the intestine of humans and warm blooded animals. A specific subgroup of coliform bacteria is feacal coliform bacteria, with the most common member in the subgroup being Escherichia coli (E.coli).


The presence of faecal coliform bacteria, though being relatively less health hazardous to human, indicates that samples may be feacal contaminated. As faecal coliform bacteria is abundance in faeces and is relatively easy to detect, it is usually used as an indicator organism of contamination. Positive results of feacal coliform or E.coli in the samples also indicate the existence of other pathogenic organisms, thus reflecting the potential health risks for individuals being exposed to samples being tested.


Enviro Labs Ltd. (ELL) has been granted HOKLAS accreditation for coliform, faecal coliform and E.coli tests. Different detection methods are employed to suit your needs. Below is a summary of coliform and E.coli tests offered by Enviro Labs.
