Disinfection is a set of measures and procedures to destroy pathogens and other microorganisms by physical or chemical means in the external environment. By disinfection number of harmful microorganisms is reduced to harmless values for human health.

The importance of carrying out disinfection is particularly evident in the food-service, educational, and similar activities, where it is a measure to prevent the outbreak and spread of infection due to microbial contamination (food, utensils, work surfaces, etc..).
