Heat disinfection of clinical waste: microbiological assessment and monitoring of effectiveness.
Simple, rapid and reproducible protocols are described for the microbiological assessment of clinical waste treatment processes, using Bacillus subtilis spore tests and end-product sampling. The use of these protocols to commission a new heat disinfection system (HDS), based on a hot oil-filled auger, and to monitor it over the first 21 months of operation is described. It is suggested that these protocols are suitable for assessment of other non-burn heat-treatment technologies.
