Disinfection is an operation to eliminate or kill micro-organisms and/or to inactivate unwanted viruses carried by contaminated inert media according to the objectives set (AFNOR standard NF T 72-101).
5 different activities are grouped under the term of disinfection:
- Bactericidal : Product that kills bacteria
- Yeasticidal : Product that kills yeasts
- Fungicide : Product that kills mushrooms (yeasts and moulds)
- Sporicidal : Product that kills bacterial spores
- Virucidal : Product that kills viruses
Thus a disinfectant can be only bactericidal, while another will be both bactericidal, fungicide and Virucidal.
- Micro-organisms are ubiquitous in the environment: water, soils, men and animals, food ...
- Bacteria colonize water-rich environments.
- Fungi preferentially colonize wetlands.
HYGIENE is INDISPENSABLE to man to protect his health, his water, his food and his ecosystem.
Why do I need to disinfect regularly?
The result of the disinfection operation is limited to the micro-organisms present at the time of the operation; Disinfection does not prevent subsequent re-contamination, therefore it must be renewed regularly.
Disinfection is an operation with a momentary result, allowing the elimination or killing of micro-organisms and/or inactivating the viruses carried on contaminated inert media as a function of the set objectives.
The result of this operation is limited to the organisms present at the time of the operation.
We only disinfect what's clean.
Regular disinfection lowers the microbial density below a risk threshold.
What is the difference between disinfection, decontamination and sterilization?
Decontamination : An operation intended to eliminate microbes, or to reduce the number on living tissues and inert objects at rates considered safe, in order to comply with the standards of hygiene and public health.
Disinfection : operation with a momentary result to eliminate or kill micro-organisms and/or to inactivate unwanted viruses carried by contaminated inert media according to the objectives set.
Sterilization : Sterilization is an operation to eliminate or kill micro-organisms carried by contaminated inert media, the result of this operation, not limited to the duration of the application, being the state of sterility.
