Abstract: The presence of Salmonella spp. on laying hen farms turns out to be a major problem for public health reasons, mainly related to foodborne illnesses that may arise due to ingestion of contaminated eggs. When Salmonella spp. infection on farms is confirmed by laboratory analysis, animal health measures are applied on the establishment, including total elimination of animals. The aim of this study is to describe three different methods of managing Salmonella enteritidis -infected laying hen farms, all of which were used within the Moselle department (France). The methods chosen, culling, use of a mobile CO 2 container, or lethal injection with T-61, depend on specific starting conditions, including the number of birds and proximity to an authorized slaughterhouse. This study, therefore, helps to identify the main problems with each method and provides recommendations for improving the management of Salmonella spp.-infected laying hen farms, where antibiotics cannot be used.
