Campylobacter is a common but decreasing cause of foodborne infections in the USA. Outbreaks are uncommon and have historically differed from sporadic cases in seasonality and contamination source. We reviewed reported outbreaks of campylobacteriosis. From 1997 to 2008, 262 outbreaks were reported, with 9135 illnesses, 159 hospitalizations, and three deaths. The annual mean was 16 outbreaks for 1997-2002, and 28 outbreaks for 2003-2008. Almost half occurred in warmer months. Foodborne transmission was reported in 225 (86%) outbreaks, water in 24 (9%), and animal contact in seven (3%). Dairy products were implicated in 65 (29%) foodborne outbreaks, poultry in 25 (11%), and produce in 12 (5%). Reported outbreaks increased during a period of declining overall incidence, and seasonality of outbreaks resembled that of sporadic infections. Unlike sporadic illnesses, which are primarily attributed to poultry, dairy products are the most common vehicle identified for outbreaks.
空肠弯曲菌是美国常见但呈下降趋势的食源性病原体。爆发并不常见，且其季节性和污染来源与散发病例不同。我们回顾了空肠弯曲菌病的报告爆发情况。1997 年至 2008 年，报告了 262 起爆发，涉及 9135 例疾病、159 例住院和 3 例死亡。1997-2002 年的年平均爆发数为 16 起，2003-2008 年的年平均爆发数为 28 起。近一半发生在温暖的月份。225 起（86%）爆发是经食物传播的，24 起（9%）是经水传播的，7 起（3%）是经动物接触传播的。65 起（29%）经食物传播的爆发与乳制品有关，25 起（11%）与家禽有关，12 起（5%）与农产品有关。报告的爆发在总体发病率下降期间增加，且爆发的季节性与散发病例相似。与主要归因于家禽的散发病例不同，乳制品是已确定的最常见的爆发源。
