From 1996 to 2004, the incidence of Salmonella Javiana infections increased in FoodNet, the U.S. national active foodborne disease surveillance programme. Contact with amphibians and consumption of tomatoes have been associated with outbreaks of S. Javiana infection. To generate and test hypotheses about risk factors associated with sporadic S. Javiana infections, we interviewed patients with laboratory-confirmed S. Javiana infection identified in Georgia and Tennessee during August-October 2004. We collected data on food and water consumption, animal contact, and environmental exposure from cases. Responses were compared with population-based survey exposure data. Seventy-two of 117 identified S. Javiana case-patients were interviewed. Consumption of well water [adjusted odds ratio (aOR) 4.3, 95% confidence interval (CI) 1.6-11.2] and reptile or amphibian contact (aOR 2.6, 95% CI 0.9-7.1) were associated with infection. Consumption of tomatoes (aOR 0.5, 95% CI 0.3-0.9) and poultry (aOR 0.5, 95% CI 0.2-1.0) were protective. Our study suggests that environmental factors are associated with S. Javiana infections in Georgia and Tennessee.
从 1996 年到 2004 年，美国国家主动食源性疾病监测计划 FoodNet 中感染沙门氏菌的发病率上升。与青蛙和接触番茄有关的感染暴发与沙门氏菌感染有关。为了产生和测试与散发性沙门氏菌感染相关的危险因素的假设，我们采访了 2004 年 8 月至 10 月在佐治亚州和田纳西州实验室确认的沙门氏菌感染患者。我们从病例中收集了食物和水的消费、动物接触和环境暴露的数据。受访者的回答与基于人群的调查暴露数据进行了比较。从 117 名确定的沙门氏菌病例患者中采访了 72 名。饮用井水（调整后的优势比[aOR]4.3，95%置信区间[CI]1.6-11.2）和接触爬行动物或两栖动物（aOR 2.6，95%CI 0.9-7.1）与感染有关。食用番茄（aOR 0.5，95%CI 0.3-0.9）和家禽（aOR 0.5，95%CI 0.2-1.0）具有保护作用。我们的研究表明，环境因素与佐治亚州和田纳西州的沙门氏菌感染有关。
