New biosensor targets pathogens in rinse water

Efficient cleaning in place (CIP) systems are essential to ensure high food safety standards in food production. In that connection, one of the top priorities for manufacturers is that the last rinse water is entirely free of pathogens, such as E. coli.

Real-time PCR-based tests are the current method of E. coli detection. The drawback is that it takes at least six hours to get the results.

AOTECH is developing an optical biosensor to carry out real-time monitoring of pathogenic bacteria in rinse water –  with a similar sensitivity range as the PCR test and a processing time of less than two minutes.

For food manufacturers, rapid and reliable CIP validation is the way to improved efficiency in food safety and quality assurance and increased consumer confidence.

AOTECH is collaborating with the Applied Photonics Group from the University of the Basque Country for this project.
