Abstract: Contamination of poultry with Salmonella occurs prior to entry into the processing facility and by cross-contamination in the processing plant. Breeder flocks, hatcheries, contaminated feed and water, and environmental sources/vectors such as litter, humans, and insects are potential pre-harvest sources of Salmonella contamination in poultry. Knowledge of key pre-harvest factors responsible for Salmonella colonization would help integrators and poultry producers in defining critical, pre-harvest control points on the farm. Intervention at these points could reduce or eliminate horizontal transmission and Salmonella positive birds arriving at the processing plants. It is difficult to improve the microbiological quality of chickens once they have reached the processing plant. Several physical and chemical decontamination procedures have been applied to poultry carcasses and have been useful in reducing the level and frequency of Salmonella on poultry carcasses at the processing plants. A combination of pre- and post-harvest intervention strategies can reduce or eliminate Salmonella on fresh poultry delivered to consumers, thereby significantly reducing the medical and productivity costs associated with salmonellosis.
