IntroductionNo official training on risk assessment universities Very limited number of Public health/preventive medicine/health staff in Vietnam have training on health risk assessmentwhile increasing health risks due to environmental healthhazards. Need to put theoretical training/teaching into practice.Willingness to develop a policy of health risk managementrelated to food, water and sanitation. Partnership and combination of common interests fromdifferent stakeholders (university, policy making) create a jointforce in developing health risk assessment approach specific toVietnamese context.
IntroductionVietnam Food Safety Law: Article 49, which stated that riskanalysis for food safety must be undertaken for:• Foods with high risk of causing food poisoning• Foods with samples taken for monitoring show ahigh violation rate in terms of food safetytechnique regulations.• The production, display and sell of foods aresuspected to cause pollution• Risk analysis for foods, production areas, foodtraders is undertaken according to managementrequirementCompliance with CODEX, WTO as country: food import-export, surveillance…
ObjectiveGeneral goal: developing a training module onhealth risk assessment related to water supply,sanitation and food in VietnamSpecific objectives: to develop a training module on heath risk assessment related towater supply, sanitation and food to test the developed training module with various stakeholders ofhealth risk assessment using approach learning by doing (perspective): policy implication, replication elsewhere
1. Develop atraining moduleon heath riskassessmentrelated to watersupply,sanitation andfood safety2. Test thedevelopedtraining modulewith variousstakeholdersusing approachlearning bydoing3.
