Effect of a Novel Sanitizer on Pathogenic, Spoilage, and Indicator Populations of Bacteria from Chicken Carcasses

Abstract

Research was conducted to determine whether a new sanitizer, Timsen (N-Alkyl dimethyl benzyl ammonium chloride-ADBAC) was effective for killing populations 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. putida, P. fragi, and Shewanella putrfaciens), aerobic bacteria, and coliform bacteria were exposed to various levels of ADBAC, then monitored to determine their survival rate. ADBAC was able to completely eliminate the pathogenic bacteria tested at concentrations of 150 ppm or less, which is much lower than the allowable use concentration of 400 ppm. ADBAC eliminated or reduced the growth of spoilage bacteria at a level of 200 ppm or less. ADBAC eliminated Escherichia coli at a concentration of 100 ppm. ADBAC significantly inhibited the growth of aerobic and coliform populations of bacteria. Therefore, Timsen (ADBAC) appears to be an effective means of eliminating pathogenic and spoilage bacteria, and the feral indicator E. coli.
