Tóm tắt
The five studies (I to V) in this dissertation describe and evaluate the public health surveillance systems and responses to foodborne outbreaks in Southern Vietnam from 2009 to 2013. Studies I to IV aim to identify vehicles, sources, causative agents, and risk factors associated with the outbreaks. These studies use various analytic methods to identify gaps and shortcomings in the surveillance and investigation of foodborne outbreaks. Study V then evaluates food-handlers' food safety knowledge, attitudes, and practices at large canteens. The main findings of these studies help to identify feasible approaches to build capacity and improve public health practices in resource-poor settings. --- We identified likely outbreak vehicles and sources in four outbreak investigations and risk factors contributing to these outbreaks, in particular inadequate personal hygiene and food hygiene practices of food-handlers. Additionally, findings of outbreak investigations showed that only severe cases sought care at hospitals, clinicians alerted public health officials to suspected outbreaks, and that these notifications were usually delayed. The notifiable disease system are generally unable to detect clusters of cases or suspected foodborne outbreaks, and foodborne notification/complaint systems were not set up to receive FBD complaints from the public. Currently, outbreak investigation reports are the only method used to track food safety, but these reports usually contain only limited information. In addition, standard epidemiologic methods were not appropriately applied in most investigations in Southern Vietnam. --- In Study V, we conducted a large survey on food safety knowledge, attitudes, and practices (KAP) and on the training needs of food-handlers in large canteens. Of the 909 food-handlers participating in the study, knowledge, attitudes, and practices were considered adequate for 26%, 36%, and 26%, respectively. The number of food-handlers reporting adequate KAP in schools was about twice as high as the number of such food-handlers in factory canteens in industrial manufacturing zones. Food-handlers' suggestions for training needs included appropriate location of the training venue at the workplace, involvement of managers, fewer trainees per course, more practical exercises, and longer course duration. --- In these studies, we found that public health surveillance systems for food safety are mainly based on foodborne outbreak investigations, response capacities to foodborne outbreaks are limited, and food-handlers' KAP are poor. We therefore recommend the following: i) For public health surveillance and response in resource-poor settings, food safety authorities and policy-makers should consider including syndromic surveillance and notification/complaint systems in food safety systems, based on existing notifiable disease reporting for infectious diseases. ii) The Vietnam Field Epidemiology Training Program should develop a strategy and plan to train outbreak response teams at all administrative levels. iii) Efforts to educate food-handlers, together with supportive supervision conducted by managers, have great potential to improve food-handlers' KAP, especially among those working in large factory canteens. iv) Further studies should investigate contributing factors in food preparation and foodborne outbreaks, the burden of foodborne diseases, and most important source.
