As a leading cause of death from a foodborne pathogen, Listeria monocytogenes continues to cause sporadic cases and outbreaks of illness. The most recent of these outbreaks in the United States involved consumption of hot dogs, with 101 cases of illness and 21 deaths reported to the Centers for Disease Control and Prevention for the years 1998-1999. Epidemiologic analysis determined that contamination levels in hot dogs were remarkably low (0.3 CFU [colony-forming units] L monocytogenes serotype 4b/g). That same year, manufacturers of hot dogs and luncheon meats collectively recalled more than 500,000 pounds of product owing to possible Listeria contamination. This article, through focus on issues such as reexamination of zero-tolerance policies, improvements in detection and enumeration procedures, the impact of epidemiologic innovations, and measures needed to further reduce the incidence of listeriosis will highlight why L monocytogenes remains a continuing challenge for the food industry.
作为食源性病原体导致死亡的主要原因，单核细胞增生李斯特菌继续引发散发病例和疾病暴发。美国最近的一次此类暴发涉及食用热狗，1998 - 1999年向疾病控制与预防中心报告了101例病例和21例死亡。流行病学分析确定热狗中的污染水平极低（0.3 CFU[菌落形成单位]单核细胞增生李斯特菌血清型4b/g）。同年，热狗和午餐肉制造商因可能受到李斯特菌污染，共召回了超过50万磅产品。本文通过关注诸如重新审视零容忍政策、改进检测和计数程序、流行病学创新的影响以及进一步降低李斯特菌病发病率所需措施等问题，将突出说明为什么单核细胞增生李斯特菌仍然是食品行业持续面临的挑战。
