EFFICIENCY OF THE POLTI SANI SYSTEM PLUS HPMed IN REDUCING MICROBIAL LOAD ON INANIMATE SURFACES

Microbial contamination is a concern to numerous industries including the medical, food and pharmaceutical industries. Methods that can reduce or eliminate microbial growth with minimal or no harm to the operator, products or end-user are desiderable. The purpose of the current project was to test the efficacy of the Polti Sani System plus HPMed in killing a selection of microorganism. These included Gram positive and Gram negative bacteria, fungi and bacterial endospores. The organisms selected for testing were considered representative of causative agents of nosocomial infection and other microbes of interest to medical, healthcare and food industries. A nebulising time of 30 seconds was found to be effec- tive in completely eliminating the viable cells of vegetative bacteria and fungi and the 97% of bacterial endospores under the same test conditions, suggesting that extended treatment is necessary to ensure complete sterilization.
