However, in the operating room a more thorough decontamination is needed because a sterile environment is necessary to reduce the risk of infection during an operation. Disinfection is the process of destroying harmful pathogens in their vegetative state and reducing the number of microorganisms to levels that no longer pose a threat to human health.
Disinfection uses antimicrobial agents on non-living objects or surfaces to destroy or inactivate microorganisms. Pasteurization: Pasteurized products have a shorter shelf life compared to sterilized product Processing steps Example is milk Sterilized milk: Various processing steps are involved during milk sterilization are shown in figure 1.
