美国甜瓜爆发李斯特菌污染事件美国甜瓜爆发李斯特菌污染事件至少造成139人患病、并有29人相继死亡，这是自1924年以来这个国家最致命的疾病爆发事件。污染源头来自科罗拉多州霍利市附近的延森农场出售的Rocky Ford品牌甜瓜。
The first illnesses began after July 31; the cantaloupes were recalled Sept. 14. Symptoms of listeriosis can take up to two months to develop in someone who has eaten contaminated food, which made the outbreak difficult to track. The Food and Drug Administration said it found listeria throughout the packing facility of the Colorado farm.
第一份病例是在7月31日之后发病；该甜瓜产品于9月14日召回。由李斯特菌引发的病症可在吃过被污染食物的人体内潜伏长达两个月后才爆发，这也增大了污染源跟踪的难度。美国FDA说，它在这家农场的整个包装线上都发现了李斯特菌。
Citing the CDC's computerized outbreak reports and public health textbooks, Robert Tauxe, deputy director of CDC's Division of Foodborne, Waterborne and Environmental Diseases, had to go back to 1924 to find a deadlier outbreak. That one, in oysters from New York City, killed about 150 people and sickened more than 1,500. It was the deadliest recorded in U.S. history.
罗伯特 陶克斯是CDC下属食物传播、水传播与环境传播疾病控制部（Division of Foodborne, Waterborne and Environmental Diseases）的副主任。借助CDC的疾病爆发报告的电脑档案以及公共卫生教科书，陶克斯找到了一起发生在1924年的更致命的细菌爆发事件。那次事件发生在纽约市，是由牡蛎引起，导致150人死亡，1500多人致病，是美国历史上有记录以来最致命的病毒爆发事件。
Graphic warnings on cigarette labels? The FDA created nine graphic pictures of the health dangers of smoking and required cigarette companies to use them. A federal judge halted it, but the Obama administration is appealing. Tobacco is the leading cause of preventable deaths in the USA and accounts for one in five deaths every year.
