The purpose of this paper is to provide guidance to food processors in controlling Listeria monocytogenes in food-processing environments. Of particular concern are outbreaks of a few to several hundred scattered cases involving an unusually virulent strain that has become established in the food-processing environment and contaminates multiple lots of food over days or months of production. The risk is highest when growth occurs in a food before it is eaten by a susceptible population. The information presented in this paper provides the basis for the establishment of an environmental sampling program, the organization and interpretation of the data generated by this program, and the response to Listeria-positive results. Results from such a program, including examples of niches, are provided. Technologies and regulatory policies that can further enhance the safety of ready-to-eat foods are discussed.
本文旨在为食品加工企业提供指导，以控制食品加工环境中的单核细胞增生李斯特菌。特别值得关注的是，出现了几例到几百例分散病例的疫情，涉及一种异常毒力的菌株，该菌株已在食品加工环境中定植，并在数天或数月的生产过程中污染多批食品。当食品在易感人群食用前生长时，风险最高。本文提供的信息为建立环境采样计划、组织和解释该计划产生的数据以及对李斯特菌阳性结果的应对措施提供了依据。文中给出了该计划的结果，包括生态位的示例。还讨论了可进一步提高即食食品安全性的技术和监管政策。
