Abstract. The elevated levels of pathogen such as Salmonella in poultry carcasses can potentially pose risk to the public health. Controlling Salmonella in poultry carcasses prior to its disposal can help in reducing Salmonella risk to the public and environment health. In order to identify the effect composting temperature on Salmonella inactivation, here we have evaluated the impacts of thermophilic temperature on Salmonella decay during poultry carcass digestions resembling composting environment. We have studied the decay of Salmonella Typhimurium LT2 in poultry carcasses at 55, 62.5 °C. The effects of mixing and non-mixing were also evaluated on the decay of Salmonella. Considering the importance of composting for disposing poultry carcasses, we anticipate that the study presented here will provide additional insight for assessing the effects of composting environment on controlling Salmonella.
