Microbial Source Tracking (MST)

Our Microbial Source Tracking (MST) testing is used to help identify point source contamination. This is an important step in controlling and managing faecal contamination using molecular techniques. In urban areas, faecal contamination arising from humans is likely to be a dominant source, test results can assist with supporting these claims. We are able to differentiate faecal contamination using digital PCR techniques between human, dog, ruminant, gull and water fowl. In addition to MST, we developed a test to identify pharmaceutical and personal care products (PPCP) as these are unique to human urban pollution. To read more about PPCP click here

Our Microbial Source Tracking testing offer is the only IANZ accredited testing of its type in New Zealand.
