Multiple foodborne illness outbreaks have been associated with the consumption of fresh produce. Investigations have indicated that microbial contamination throughout the farm-to-fork continuum often contributed to these outbreaks. Researchers have hypothesized that handling practices for leafy greens in restaurants may support contamination by and proliferation and amplification of pathogens that cause foodborne illness outbreaks. However, limited data are available on how workers handle leafy greens in restaurants. The purpose of this study was to collect descriptive data on handling practices of leafy greens in restaurants, including restaurant characteristics, types of leafy greens used, produce receipt, and food safety training and certification. As a federal collaborative partner with the Environmental Health Specialists Network (EHS-Net) of the Centers for Disease Control and Prevention, the U.S. Food and Drug Administration (FDA) recommended that EHS-Net participants survey handling practices for leafy greens in restaurants. The recommendations in the FDA's Guide to Minimize Microbial Food Safety Hazards of Leafy Greens are significant to this study for comparison of the results. The survey revealed that appropriate handling procedures assist in the mitigation of other unsafe handling practices for leafy greens. These results are significant because the FDA guidance for the safe handling of leafy greens was not available until 2009, after the survey had been completed. The information provided from this study can be used to promote additional efforts that will assist in developing interventions to prevent future foodborne illness outbreaks associated with leafy greens.
已发生多起因食用新鲜农产品而导致的食源性疾病暴发事件。调查表明,从农场到餐桌的整个过程中微生物污染通常是导致这些暴发的原因。研究人员推测,餐厅中绿叶蔬菜的处理方式可能会支持食源性疾病暴发病原体的污染、增殖和扩增。然而,关于餐厅工作人员如何处理绿叶蔬菜的数据有限。本研究旨在收集餐厅中绿叶蔬菜处理方式的描述性数据,包括餐厅特征、使用的绿叶蔬菜类型、农产品采购以及食品安全培训和认证。作为疾病预防控制中心环境卫生专家网络 (EHS-Net) 的联邦合作夥伴,美国食品和药物管理局 (FDA) 建议 EHS-Net 参与者调查餐厅中绿叶蔬菜的处理方式。FDA 的《最大限度减少绿叶蔬菜微生物食品安全危害指南》中的建议与本研究密切相关,可用于比较结果。调查显示,适当的处理程序有助于减轻其他不安全的绿叶蔬菜处理方式。这些结果意义重大,因为 FDA 对绿叶蔬菜安全处理的指南直到 2009 年才发布,此时调查已经完成。本研究提供的信息可用于促进进一步的努力,以协助制定干预措施,防止未来与绿叶蔬菜相关的食源性疾病暴发。
