Effect of a novel sanitizer on pathogenic, spoilage, and indicator populations of bacteria from chicken carcasses

Research was conducted to determine whether a new sanitizer, Timsen (N-Alky l dimethyl benzyl ammonium chloride-ADBAC), was effective for killing popul ations of bacteria that are of concern to the poultry industry. Populations of pathogenic bacteria (Salmonella enteritidis, Staphylococcus aureus, and Listeria monocytogenes), spoilage bacteria (Pseudomonas fluorescens, P. pu tida, P. fragi, and Shewanella putrefaciens), aerobic bacteria, and colifor m bacteria were exposed to various levels of ADBAC, then monitored to deter mine their survival rate, ADBAC was able to completely eliminate the pathog enic bacteria tested at concentrations of 150 ppm or less, which is much lo wer than the allowable use concentration of 400 ppm. ADBAC eliminated or re duced the growth of spoilage bacteria at a level of 200 ppm or less. ADBAC eliminated Escherichia coli at a concentration of 100 ppm. ADBAC significan tly inhibited the growth of aerobic and coliform populations of bacteria. T herefore, Timson (ADBAC) appears to be an effective means of eliminating pa thogenic and spoilage bacteria, and the fecal indicator E. coli.
