The system includes a storage including records created for every product at every stage and a processor operated by first and second processes. Each record includes a first stage information at which the food product is processed, a first time information for specifying the time period of processing at the first stage, a second stage information at which the livestock product processed at the first stage is received as material and a second time information for specifying the time period of processing at the second stage. The first process specifies a target record whose first stage and time information are coincident with that of an original product. The second process specifies a new target record whose first stage and time information are coincident with the second stage and time information of the previous target record. The second process is repeated until a new target record cannot be specified.
