Technical Abstract: Salmonella infections in pigs is well known resulting in creased morbidity and mortality. Additionally, economic loss for the producer can be significant. This chapter details the historical perspective of infection primarily associated with Salmonella choleraesuis, the host-adapted serotype, and S. typhimurium. Although both salmonellae manifest clinical illness in swine, severity and long term carriage of the organism in the swine population can differ. Detection of the organism is also problematic and many different tests have been designed for this purpose. Tests can encompass culture techniques, serologic detection, and molecular methods. While all are useful, no one test provides superior results, nor can they determine if a mixed infection is occurring. The public health aspects are also discussed as it is possible for salmonella to be transmitted through the food chain to humans. Methods are currently being devised to reduce or eliminate Salmonella from the swine production environment and include alternatives to the use of antimicrobials, competitive exclusion and use of vaccine. This chapter highlights all of the areas and is useful as a reference source for Salmonella in pigs.
