E coli & Coliforms Testing
At SESALAB, we provide E coli & Coliforms Testing to assess surface contamination in various environments. Using advanced laboratory techniques, we analyse surface swabs and other media to detect Escherichia coli (E. coli) and coliform bacteria, which serve as key indicators of hygiene, water quality, and potential faecal contamination.
Our NATA accredited laboratory ensures accurate and reliable results, helping businesses and industries maintain health and safety compliance. Whether for food production, healthcare, commercial facilities, or environmental monitoring, our testing services support effective sanitation strategies and risk management.
- Laboratory analysis of E Coli & Coliforms – in surface swabs and other media as indicators of surface contamination.
