食源性疾病的流行病学正在发生变化。新的病原体已经出现，有些已经在世界范围内传播。包括沙门氏菌、大肠杆菌O157：H7、弯曲杆菌和小肠结肠炎耶尔森氏菌在内的许多细菌都在健康的食用动物体内有宿主，并从那里传播到越来越多的食物中。这些病原体导致数百万例散发性疾病和慢性并发症，以及许多州和国家的大规模和具有挑战性的疫情。结合快速分型方法、集群识别和协作流行病学调查的改进监测可以识别和阻止大规模、分散的疫情。对散发病例的暴发调查和病例对照研究可以确定感染源，并指导制定具体的预防战略。更好地了解病原体如何在动物宿主中持续存在对于成功的长期预防也至关重要。过去，食源性疾病的主要挑战在于防止污水或动物粪便污染人类食物。未来，食源性疾病的预防将越来越依赖于控制动物本身消耗的饲料和水的污染。
The epidemiology of foodborne disease is changing. New pathogens have emerged, and some have spread worldwide. Many, including Salmonella, Escherichia coli O157:H7, Campylobacter, and Yersinia enterocolitica, have reservoirs in healthy food animals, from which they spread to an increasing variety of foods. These pathogens cause millions of cases of sporadic illness and chronic complications, as well as large and challenging outbreaks over many states and nations. Improved surveillance that combines rapid subtyping methods, cluster identification, and collaborative epidemiologic investigation can identify and halt large, dispersed outbreaks. Outbreak investigations and case-control studies of sporadic cases can identify sources of infection and guide the development of specific prevention strategies. Better understanding of how pathogens persist in animal reservoirs is also critical to successful long-term prevention. In the past, the central challenge of foodborne disease lay in preventing the contamination of human food with sewage or animal manure. In the future, prevention of foodborne disease will increasingly depend on controlling contamination of feed and water consumed by the animals themselves.
