CAPE TOWN - A portable device that can detect the presence of E. coli in water has been developed by the Council of Scientific & Industrial Research (CSIR).

The ColiSpot aims to provide waste water treatment facilities with same day results as opposed to the 24-hour waiting period when samples are sent for laboratory testing.

The Council of Scientific & Industrial Research's Klariska Moodley Says that the device might also be rolled out to various communities.

“The sensor has been developed to be easy to use and a low-cost device. It consists of a low cost natural flow sensor, very similar to a home-based pregnancy test, where two lines indicate positive results and one line indicates negative results.”

According to CSIR, the ColiSpot addresses the shortcomings of traditional techniques by reducing the total detection time for E. coli and negating the need for a fully equipped laboratory.
