This study examined relationships between foodborne outbreak investigation characteristics, such as the epidemiological methods used, and the success of the investigation, as determined by whether the investigation identified an outbreak agent (i.e. pathogen), food item and contributing factor. This study used data from the Centers for Disease Control and Prevention's (CDC) National Outbreak Reporting System and National Environmental Assessment Reporting System to identify outbreak investigation characteristics associated with outbreak investigation success. We identified investigation characteristics that increase the probability of successful outbreak investigations: a rigorous epidemiology investigation method; a thorough environmental assessment, as measured by number of visits to complete the assessment; and the collection of clinical samples. This research highlights the importance of a comprehensive outbreak investigation, which includes epidemiology, environmental health and laboratory personnel working together to solve the outbreak.
本研究考察了食源性疾病暴发调查特征（如使用的流行病学方法）与调查结果（即是否确定了暴发病原体、食物种类和促成因素）之间的关系。本研究利用疾病预防控制中心（CDC）国家暴发报告系统和国家环境评估报告系统的数据，确定了与暴发调查成功相关的调查特征。我们发现了一些增加暴发调查成功率的调查特征：采用严格的流行病学调查方法；全面的环境卫生评估，通过完成评估的访问次数来衡量；以及临床样本的采集。这项研究强调了全面暴发调查的重要性，包括流行病学、环境卫生和实验室人员共同合作解决暴发问题。
