International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork
Iowa State University Conferences and Symposia

The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.

Abstract

Salmonella are now being monitored by the Food Safety Inspection Service of the USDA for purposes of process control in slaughter plants, and as a sentinel organism for emerging antimicrobial resistance (I). Public concerns about the emergence of foodborne bacteria with multi-resistant phenotypes, and about the use of antimicrobials in food animals, are increasing. Despite considerable research, the epidemiology of asymptomatic Salmonella in pigs is poorly understood (2). The purpose of this paper is to examine the association between nursery prevalence of Salmonella and finisher prevalence, and to describe patterns of antimicrobial use and antimicrobial resistant Salmonella in modern swine rearing facilities.
