WASHINGTON — Washing your hands with soap from bulk-soap-refillable containers might not be as hygienic as you think, according to the Science Blog.

New research published in the May issue of Applied and Environmental Microbiology suggests that the containers can actually increase bacteria on the hand and could play a role in the transmission of disease, the article stated.

According to the article, bulk-soap-refillable dispensers, which have the new soap poured directly into a dispenser, are the predominant soap dispenser type in community settings.

This is in contrast to sealed-soap dispensers, which can be refilled by inserting a new bag or cartridge of soap, cutting down on possible bacteria contamination, the article noted.

"Handwashing with soap and water is a universally accepted practice for reducing the transmission of potentially pathogenic microorganisms. However, liquid soap can become contaminated with bacteria and poses a recognized health risk in health care settings," said Carrie Zapka from GOJO Industries, the lead researcher on the study that also included scientists from BioScience Laboratories and the University of Arizona, Tucson.
