Foodborne diseases remain an important public health problem in the United States. The Foodborne Diseases Active Surveillance Network (FoodNet) of CDC's Emerging Infections Program collects data from 10 U.S. states on diseases caused by enteric pathogens transmitted commonly through food. FoodNet is an active, population-based surveillance system for these laboratory-confirmed infections. This report describes preliminary surveillance data for 2008 and trends since 1996. In 2008, the estimated incidence of infections caused by Campylobacter, Cryptosporidium, Cyclospora, Listeria, Shiga toxin-producing Escherichia coli (STEC) O157, Salmonella, Shigella, Vibrio, and Yersinia did not change significantly when compared with the preceding 3 years. For most infections, incidence was highest among children aged <4 years, whereas the percentage of persons hospitalized and the case fatality rate were highest among persons aged >/=50 years. None of the Healthy People 2010 targets for reduction of foodborne pathogens (objective 10-1) were reached in 2008. The lack of recent progress points to gaps in the current food safety system and the need to continue to develop and evaluate food safety practices as food moves from the farm to the table.
食源性疾病在美国仍然是一个重要的公共卫生问题。美国疾病控制与预防中心新发传染病项目的食源性疾病主动监测网络（FoodNet）从美国10个州收集由通常经食物传播的肠道病原体引起的疾病数据。FoodNet是一个针对这些实验室确诊感染的基于人群的主动监测系统。本报告描述了2008年的初步监测数据以及自1996年以来的趋势。2008年，与前3年相比，弯曲杆菌、隐孢子虫、环孢子虫、李斯特菌、产志贺毒素大肠杆菌（STEC）O157、沙门氏菌、志贺氏菌、弧菌和耶尔森菌引起的感染估计发病率没有显著变化。对于大多数感染，发病率在4岁以下儿童中最高，而住院患者百分比和病死率在50岁及以上人群中最高。2008年未实现《健康人民2010》中减少食源性病原体的任何目标（目标10-1）。近期缺乏进展表明当前食品安全体系存在漏洞，并且随着食物从农场到餐桌的流转，需要继续制定和评估食品安全措施。
