美国每年约有140万人感染沙门氏菌，这是一种常见的食源性疾病;老年人（65岁或以上）最容易感染。1997年，美国农业部引入了病原体减少和危害分析及关键控制点系统（PR/HACCP），要求在加工肉类产品（如肉鸡）的各种设施中定期进行沙门氏菌检测。缺乏PR/HACCP对沙门氏菌相关住院的影响评估。1991-2004年美国老年人的住院记录来自医疗保险和医疗补助服务中心。谐波回归分析进行评估的长期趋势，沙门氏菌相关的住院治疗前和后的HACCP时期。季节性特征的结果，在九个人口普查区的连续美国也推导和对比。1997年后，除南大西洋、东南中部和西南中部外，大多数地区的预测发病率都有所下降。这三个部门还表现出较高的总体住院率，明显的季节性模式，以及在一年中第32至34周达到高峰的一致时间。HACCP的影响在地理上是不同的。进一步的沙门氏菌预防计划应针对南大西洋、东南中部和西南中部地区。需要进一步研究，以确定最佳方案类型和实施时机。
About 1.4 million Salmonella infections, a common food-borne illness, occur in the U.S. annually; the elderly (aged 65 or above) are most susceptible. In 1997, the USDA introduced the Pathogen Reduction and Hazard Analysis and Critical Control Points Systems (PR/HACCP) which demands regular Salmonella testing in various establishments processing meat products, such as broiler chickens. Impact evaluations of PR/HACCP on hospitalizations related to Salmonella are lacking. Hospitalization records of the U.S. elderly in 1991-2004 were obtained from the Centers of Medicare and Medicaid Services. Harmonic regression analyses were performed to evaluate the long-term trends of Salmonella-related hospitalizations in pre- and post-HACCP periods. Seasonal characteristics of the outcome in the nine Census divisions of the contiguous U.S. were also derived and contrasted. Predicted rates decreased in most divisions after 1997, except South Atlantic, East South Central, and West South Central. These three divisions also demonstrated higher overall hospitalization rates, pronounced seasonal patterns, and consistent times to peak at about 32nd to 34th week of the year. The impact of HACCP was geographically different. South Atlantic, East South Central, and West South Central divisions should be targeted in further Salmonella preventive programs. Further research is needed to identify the best program type and timing of implementation.
