Abstract: The sanitary management system S includes a plurality of portable communication terminal devices 10, a manager terminal device 20 and a server device 40. The server device 40: (1) extracts two or more feature values related to the color of each pixel constituting a culture medium image; (2) executes statistical analysis based on distribution of pixels of the culture medium image by using a coordinate system prescribed by the extracted two or more feature values of each pixel, and calculates a linear function prescribing relation of the two or more feature values in each pixel; and (3) detects the colonies in the culture medium image based on the calculated linear function and counts the number of colonies.

Abstract: The sanitary management system extracts food produced or inspected using a work line including one or more production process or inspection process as a specimen, and registers culture medium information obtained by a portable communication terminal device before and after culturing the extracted specimen to a server device in correspondence with work line related information related to the work line including information of sanitary management of the work line from which the specimen is extracted.
