In 1997, the Foodborne Diseases Active Surveillance Program (FoodNet) conducted active surveillance for culture-confirmed cases of Campylobacter, Escherichia coli O157, Listeria, Salmonella, Shigella, Vibrio, Yersinia, Cyclospora, and Cryptosporidium in five Emerging Infections Program sites. FoodNet is a collaborative effort of the Centers for Disease Control and Prevention's National Center for Infectious Diseases, the United States Department of Agriculture's Food Safety and Inspection Service, the Food and Drug Administration's Center for Food Safety and Applied Nutrition, and state health departments in California, Connecticut, Georgia, Minnesota, and Oregon. The population under active surveillance for foodborne infections was approximately 16.1 million persons or roughly 6% of the United States Population. Through weekly or monthly contact with all clinical laboratories in these sites, 8,576 total isolations were recorded: 2,205 cases of salmonellosis, 1,273 cases of shigellosis, 468 cases of cryptosporidiosis, 340 of E. coli O157:H7 infections, 139 of yersiniosis, 77 of listeriosis, 51 of Vibrio infections, and 49 of cyclosporiasis. Results from 1997 demonstrate that while there are regional and seasonal differences in reported incidence rates of certain bacterial and parasitic diseases, and that some pathogens showed a change in incidence from 1996, the overall incidence of illness caused by pathogens under surveillance was stable. More data over more years are needed to assess if observed variations in incidence reflect yearly fluctuations or true changes in the burden of foodborne illness.
1997年，食源性疾病主动监测项目（FoodNet）在五个新发传染病项目点对经培养确诊的弯曲杆菌、大肠杆菌O157、李斯特菌、沙门氏菌、志贺氏菌、弧菌、耶尔森氏菌、环孢子虫和隐孢子虫病例进行了主动监测。FoodNet是疾病控制与预防中心国家传染病中心、美国农业部食品安全与检验局、食品药品管理局食品安全与应用营养中心以及加利福尼亚州、康涅狄格州、佐治亚州、明尼苏达州和俄勒冈州卫生部门的合作项目。接受食源性感染主动监测的人群约为1610万人，约占美国人口的6%。通过与这些地点的所有临床实验室每周或每月联系，共记录到8576例病原体分离：2205例沙门氏菌病、1273例志贺氏菌病、468例隐孢子虫病、340例大肠杆菌O157:H7感染、139例耶尔森氏菌病、77例李斯特菌病、51例弧菌感染和49例环孢子虫病。1997年的结果表明，虽然某些细菌和寄生虫疾病的报告发病率存在地区和季节性差异，且一些病原体的发病率与1996年相比有所变化，但受监测病原体导致的疾病总体发病率稳定。需要更多年份的更多数据来评估观察到的发病率变化是反映年度波动还是食源性疾病负担的真实变化。
