WASHINGTON — Handwashing with antibacterial soap produces statistically greater reductions in bacteria on the skin when compared to using non-antibacterial soap, according to a press release.
Those are the findings of a review of two dozen relevant published studies — analyzing the effectiveness of antibacterial soaps — featured in the November 2011 edition of the peer-reviewed Journal of Food Protection, the release stated.
According to the release, researchers Donald Schaffner and Rebecca Montville of Rutgers University''s Food Science Department conducted a quantitative analysis of existing data in order to determine if there was a difference in effectiveness between antibacterial and non-antibacterial soaps.
"A difference in the effectiveness of antimicrobial and non-antimicrobial soaps appears to exist and is repeatedly observed through a variety of analyses; antimicrobial soap is consistently and statistically always more effective than non-antimicrobial soap," the researchers wrote.
"Although differences in efficacy between antimicrobial and non-antimicrobial soap may be relatively small, they do exist, and small but significant differences in pathogen levels on hands can have a significant effect on public health," Schaffner and Montville added.
