Abstract

The prevalence of Salmonella within poultry environments and on poultry products has been well documented. However, there has not been a study documenting the effect of utilizing used litter in newly constructed commercial broiler houses on Salmonella status or on the rate and source of Salmonella contamination within new houses. Objectives of this study are to 1) determine environmental source and rate of Salmonella spp. colonization in two newly constructed broiler houses 2) to evaluate the effect of mixing used broiler litter with clean litter in a new broiler house. Results of this study suggest that Salmonella contamination of the poultry house environment occurred within the first 2-4 weeks of bird placement and that the source of contamination may have been the chicks themselves. Litter inoculation may be beneficial in reducing Salmonella levels within the first flock if it is known that the chicks are already contaminated with Salmonella spp.
