Interpretive Summary:

Technical Abstract: Salmonellosis has long been recognized as a clinical problem in swine, manifesting itself either as an enterocolitis or a septicemia. However, there exists over 2,000 species of Salmonella besides the two Salmonella species that are known swine pathogens. In recent years, more attention has been directed towards these other Salmonella spp. To ascertain their role in foodborne illness. The USDA:APHIS:VS conducted a study of the health and management of grower/finisher swine as part of the National Animal Health Monitoring System's (NAHMS) Swine '95:Grower/Finisher study. One of the primary objectives of this study was to describe the shedding of Salmonella by late finishers. The study was conducted on 418 farms in the top 16 swine states. Of these, 152 farms participated in the collection of fecal samples (50 samples per farm) from pens containing late finishers. Samples were tested for Salmonella and questionnaires were used to obtain management data regarding feed management, environmental conditions, vaccination policies, and other factors. This paper describes the management factors associated with those farms containing finishing pigs shedding Salmonella. Such information should aid the swine practitioner in reducing the shedding of Salmonella on swine farms, thereby minimizing the risk of Salmonella contamination in the food chain.
