Document Summary
Sterilization removal or destruction of all organisms so they can no longer multiply or revive. Sterile item is free of microbes including endospores and viruses but . Doe s not consider prions (not destroyed by standard sterilization) Disinfection elimination of most or all pathogens. Pasteurization brief heating to reduce number of spoilage. Decontamination reduced pathogens to levels considered safe to handle. Sanitization substantially reduced microbial population that meets accepted health standard (not a specific level of control) Preservation process of delaying spoilage of foods and other perishable products. Add bacteriostatic preservative (growth-inhibiting but do not kill) Microbial control methods depends upon situation and level of control required. Routine control washing and scrubbing with soaps and detergents. Beneficial skin microbiota reside deeper in skin = no effect. Pores typically has no contact with soap and bacteria here are in biofilm. Patients more susceptible to infection due to weakened condition. High concentration of infectious disease in confined area (pathogens)
