Foodborne disease (FBD) is a significant public health concern worldwide, particularly among school-aged children, who are more susceptible to consuming unsafe or unhealthy snacks sold around schools. Poor hygiene, lack of parental supervision, and limited knowledge about food safety often contribute to the high incidence of foodborne illnesses in this population. Therefore, improving children’s understanding and behavior toward healthy snack selection is crucial in preventing FBD. This study aims to determine the effect of the Calgary Family Intervention Model (CFIM) approach on the selection of healthy snacks for the prevention of foodborne disease among schoolchildren at SDN 38 Bengkulu City. The CFIM emphasizes collaboration between children and their families to promote health behavior change through education, communication, and family engagement. This research employs a quantitative method with a quasi-experimental design using a one-group pre-test and post-test approach. The sample consisted of 41 second-grade students at SDN 38 Bengkulu City, selected through a total sampling technique. Data were collected using a structured knowledge questionnaire and analyzed statistically using the Wilcoxon Signed Rank test to evaluate differences before and after the intervention. The results showed a significant improvement in students’ knowledge regarding the selection of healthy snacks after the CFIM-based intervention (p < 0.05). These findings indicate that the CFIM approach effectively enhances children’s awareness and decision-making skills in choosing safe and nutritious foods. It is expected that this model can be implemented as a sustainable educational strategy to promote food safety and overall health among school-aged children.
