Purpose: This study aimed to assess the impact of the smart Hazard Analysis and Critical Control Point(HACCP) system on job performance, job satisfaction, and job stress of dietitians in the school meal environment. Methods: Leveraging the Internet of Things (IoT) and real-time data monitoring, the smart HACCP system automates essential hygiene management tasks, reducing manual workload and enhancing the accuracy of critical control point (CCP) records. A survey was conducted among 309 dietitians in the Gyeonggi and Seoul regions who implemented this system, from July 10th to August 14th, 2024. Results: The findings indicated that the smart HACCP system decreased cross-contamination risks and enabled corrective actions up to 31.5% faster in inspection tasks, thereby enhancing food safety and operational efficiency. The system also reduced job stress by 31.5% in inspection tasks and by 13.8% in food-contact surface sanitation, while significantly improving job satisfaction in tasks related to temperature control and surface sanitation. This fostered a more supportive work environment and overall job satisfaction for dietitians. Conclusion: By automating hygiene monitoring, such as refrigerator temperatures and surface cleanliness, the smart HACCP system allows dietitians to focus on core responsibilities, enhancing working conditions and food safety standards in school meals. These findings support the broader applications of smart HACCP in school meal settings.
