The antimicrobial activities of chitosan against foodborne pathogens have been extensively investigated in the food industry
However, to the best of our knowledge, nothing is yet known on the effect of chitosan against Salmonella in poultry. Therefore, this study was designed to evaluate the effect of dietary chitosan on ante mortem control of Salmonella enterica serovar Typhimurium (ST) recovery via in vitro crop assays and infection and horizontal transmission in broiler chickens.
