Reduction of Microorganisms on Beef Surfaces with Electricity and Acetic Acid .

This study determined the effect of a 2% acetic acid spray, pulsed-power electricity, pulsed-power electricity with a spray of sterile deionized water, and a combination of acetic acid spray and pulsed-power electricity in reducing the pathogens Escherichia coli O157 and Salmonella typhimurium and aerobic plate counts on beefsteaks compared to an inoculated control. Ten steaks per treatment were inoculated with 1 ml of E. coli O157 (l0 CFU/ml) or S.
