👉 Recontamination is a process in which a material that was previously contaminated with a contaminant is again contaminated. This can occur during the cleaning or disinfection of an object, such as a surface or equipment. The purpose of recontamination is to remove any residual contaminants from the cleaned area. Recontamination occurs when the same contaminant is present on the surface after it has been removed by cleaning agents or other means. In this case, the contamination can be lost during the cleaning process and
