Technical Abstract: Recently, our laboratory demonstrated that water administration of lactic acid during feed withdrawal is effective in reducing crop contamination, however, it also decreases water consumption. The present study was conducted to determine the efficacy of sodium bisulfate (i.e. sodium acid sulfate; SAS) in reducing Salmonella crop contamination and its effect upon water consumption. Two treatment groups; SAS and lactic acid were compared to untreated controls. Crop contamination with Salmonella was significantly reduced by SAS treatment (17/60; 28.3%) compared to lactic acid (22/58; 37.9%) and controls (29/59; 49.1%). Water consumption for the SAS group (30.4 ml/bird) was similar to the controls (30 ml/bird), however a 55% decrease in water consumption was observed in the lactic acid group when compared to controls (13.6 ml). These studies suggest that incorporation of SAS in the drinking water during pre-transport feed withdrawal may reduce Salmonella contamination of crops which should reduc broiler carcass contamination with Salmonella during processing.
