2. Surface contamination
Controlling surface hygiene means adapting the design of the environment, the choice of coatings and the methods and frequency of contaminant elimination to the activities carried out in the environment in question. A distinction is made between open surfaces (partitions, ceilings, floors, furniture, equipment, etc.) and the closed surfaces of machines or equipment.
2.1 Mechanisms of surface contamination
Surfaces constitute a support that can receive and host both dirt and micro-organisms. When microorganisms come into contact with surfaces, either by sedimentation or by contact, they can adhere via physico-chemical interactions. These interactions depend on the physico-chemical surface properties of both the microorganisms and the coating. Surface roughness...
