Effect of sanitizers applied by electrostatic spraying on pathogenic and indicator bacteria attached to the surface of eggs

Research was conducted to compare the effectiveness of BioSentry 904 and Biox H applied by an electrostatic spraying system for killing populations of bacteria that are of concern to the poultry industry. Populations of pathogenic bacteria Salmonella enteritidis, Staphylococcus aureus, and Listeria monocytogenes and the indicator bacterium Escherichia coli were applied to eggs and allowed to attach for 1 h. BioSentry 904 completely eliminated all S. enteritidis on 100, 93, and 60% of eggs in experiments 1, 2, and 3, respectively. BioSentry Biox H completely eliminated all S. enteritidis on 100, 93; and 93% of eggs in experiments 1, 2, and 3, respectively. BioSentry 904 completely eliminated all S. aureus on 100, 87, and 100% of eggs in experiments 1, 2, and 3, respectively. BioSentry Biox H completely eliminated all S. aureus on 100, 100, and 80% of eggs in experiments 1, 2, and 3, respectively. BioSentry 904 completely eliminated all L. monocytogenes on 100% of eggs in experiments 1, 2, and 3. BioSentry Biox H completely eliminated all L. monocytogenes on 93, 87, and 73% of eggs in experiments 1, 2, and 3, respectively. Biosentry 904 completely eliminated all E. coli on 93, 93, and 60% of eggs in experiments 1, 2, and 3, respectively. BioSentry 904 and Biox H completely eliminated all E. coli on 93% of eggs in experiments 1, 2, and 3, respectively. Biosentry 904 and Biox H were extremely effective when used in conjunction with electrostatic spraying for eliminating pathogenic and indicator populations of bacteria from eggshell surfaces.
