Abstract
A sanitation management system maintains records of exemplary locations on an item to be sanitized and indicates those locations to a person or system charged with applying a pathogen surrogate prior to a sanitation process. The sanitation management system maintains records of where the pathogen surrogate was applied prior to the sanitation process. Following the sanitation process, the sanitation management system indicates to an inspector, or an inspection system, locations of where the pathogen surrogate was applied for the purpose of facilitating testing of the sanitation process by checking for the presence of the pathogen surrogate at some or all of those locations. This can ensure that the inspection process is relevant to the sanitation process and less likely to generate false negatives where the inspection finds a lack of the pathogen surrogate not due to cleaning, but due to lack of application of the pathogen surrogate.
