To investigate a multi-state outbreak of Salmonella bredeney.
Case interviews followed by an age and neighbourhood matched case control study.
People with laboratory-confirmed S. bredeney and controls matched on age and geographical location in New South Wales, the Australian Capital Territory, Queensland and Victoria.
We identified 157 persons with S. bredeney spread throughout the eastern states and the ACT. In the matched analysis, cold meat and chicken demonstrated a significant odds ratio of 4.4 (p = 0.017) and 4.2 (p = 0.02) respectively. Among primary cases, the odds ratio for chicken was 6.0 (p = 0.01) and for ground pepper was 3.75 (p = 0.04).
The most likely source of this outbreak was a product contaminated at the point of manufacture and distributed widely within NSW and the ACT and, to a lesser extent, Queensland (Brisbane) and Melbourne. The most probable food is a meat or chicken product, followed by substantial cross contamination of other meat products at retail outlets, which served to amplify the outbreak.
调查布雷登尼沙门氏菌的多州暴发情况。
病例访谈，随后进行年龄和社区匹配的病例对照研究。
新南威尔士州、澳大利亚首都直辖区、昆士兰州和维多利亚州实验室确诊的布雷登尼沙门氏菌感染患者以及年龄和地理位置匹配的对照者。
我们确定了157例感染布雷登尼沙门氏菌的患者，分布在东部各州和澳大利亚首都直辖区。在匹配分析中，冷肉和鸡肉的优势比分别为4.4（p = 0.017）和4.2（p = 0.02）。在原发病例中，鸡肉的优势比为6.0（p = 0.01），胡椒粉的优势比为3.75（p = 0.04）。
此次暴发最可能的源头是一种在生产环节被污染的产品，该产品在新南威尔士州和澳大利亚首都直辖区广泛分销，在昆士兰州（布里斯班）和墨尔本的分销范围较小。最有可能的食物是肉类或鸡肉产品，其次是零售网点其他肉类产品的大量交叉污染，这加剧了此次暴发。
