To ensure that the HACCP safety management system functions effectively, it is important to comply with the basic management items known as prerequisite programs (PRP) that serve as a foundation. Among the management items of PRP, "sanitation management of facilities and equipment" and "sanitation management of drainage and waste" are specified in relation to daily cleaning. Since daily cleaning poses a significant burden on the site, it is our mission to contribute to alleviating this burden, even slightly, through the "HACCP support drainage system." [About PRP Supporting HACCP] ■ HACCP: Management of critical processes ■ PRP (Prerequisite Program): Daily and general work management ■ 5S (7S) activities: Rationalization of production and manufacturing actions *For more details, please refer to the PDF materials or feel free to contact us.

"HACCP" is one of the food hygiene management methods, a safety management system that organizes, analyzes, and manages the manufacturing process. By breaking down the manufacturing process into smaller steps and managing risks at each stage, it is possible to quickly identify and address the cause of any food incidents that may occur. Since June 2020, the obligation for hygiene management based on HACCP has been implemented for all businesses handling food, such as school meal kitchens and food factories, with a one-year grace period, leading to the complete obligation for the introduction and operation of HACCP starting in June 2021. This document provides a clear introduction to "HACCP" and explains the benefits of its implementation in detail. Please feel free to download and review it.
