The effect of alcohol hand rub was tested in eradicating Escherichia coli, and compared with hand wash using ozonized tap water or soap and water. Alcohol eradicated all bacteria in 10 out of 35 participants, but with an average (SD) of 2330 (4227) cfu/mL left after disinfection, whereas ozonized water removed all bacteria in 10 out of 55 participants, with an average of only 538 (801) cfu/mL left (P = 0.045). Soap washing was the most effective with total removal of bacteria in six out of 20 participants, with an average of 98 (139) cfu/mL (P = 0.048 and 0.018 versus ozonized water and alcohol, respectively).

测试了酒精擦手液在消除大肠杆菌中的效果，并与使用臭氧化的自来水或肥皂和水的洗手液进行了比较。酒精可消灭35名参与者中的10名所有细菌，但消毒后平均剩余（SD）为2330（4227）cfu / mL，而臭氧水可去除55名参与者中的10名，所有细菌均只有538（ 801）剩余cfu / mL（P  = 0.045）。在20个参与者中有6个参与者中，肥皂洗涤最有效，能完全去除细菌，平均为98（139）cfu / mL（ 相对于臭氧水和酒精，P分别为0.048和0.018）。
