Popis: An assessment system using various microbial methods was developed for the detection of residual, surface-attached microbes and soil on surfaces after sanitation. The microbial methods tested were: conventional cultivation, microscopy using image analysis after staining with acridine orange (AO), 5-cyano-2,3-ditolyl tetrazolium chloride/4′, 6-diamidino-2-phenylindole (CTC-DAPI) and LIVE/DEAD stains, impedance measurements, viable counts with 2,3,5-triphenyltetrazolium chloride (TTC) agar and ATP measurements. A test rig was used for the trials with four different low-pressure cleaning procedures (pressure
