Survivability of Salmonella senftenberg W775 in Cattle Slurry under Various Temperature Conditions
Abstract:The effect of varied temperatures of cattle slurry storage conditions on the rate of elimination of Salmonella senftenberg W775 bacilli was studied. It was demonstrated that a temperature of 4°C had a stabilizing effect on the bacteria, which resulted in the longest time of Salmonella bacilli survivability. A regression analysis defined the daily loss of the bacteria. The rate of elimination of Salmonella amounted to 0.26 log/day at a temperature of 4°C, which resulted in a theoretical time of bacteria survivability of 42 days. At a temperature of 20°C, faster inactivation of Salmonella cells was shown, which was defined as 0.30 log/day. Salmonella senftenberg W775 bacilli at 30°C were able to survive 13 days, at a daily population loss of 0.87 log. The Salmonella cells died at 40°C (10 days). A significant relationship between the survival period of Salmonella senftenberg W 775 in cattle slurry and the temperature of its storage was noted.
