Salmonella spp are pathogens that can cause serious human disease.  Salmonella spp. can hide in the intestines of swine without them being sick, and when they shed it in their feces, it can be a potential pathway of transmission to humans. 

Pigs fed MSP[RS] Resistant Starch had lower levels of fecal shedding of Salmonella, and MSP[RS] Resistant Starch had the most striking impact on the gut microbial communities compared to other strategies including resistant corn starch.  The shift in microbial communities in pigs fed MSP[RS] resulted in higher SCFA’s, which was found to reduce colonization and shedding of Salmonella indicating that MSP[RS] Resistant Starch may be a viable option for preventing Salmonella colonization and shedding.
