Bar Soap Bacteria
Country: United States
Date: August 2008
What is the name of the bacteria that grows on bar soap?
Is there a specific type?
While physical contact with bar soap "theoretically" is greater than
liquid soap from a dispenser (except for the fact that hands come into
contact with the pump mechanism for liquid soaps) I know of no evidence
that bacteria of any sort "grow" on bar soap -- at least from my web
search on those and related search terms. Without appropriate controlled
"double blind" experiments showing to the contrary, my challenge is that
there is no significant risk. If liquid soap manufacturers have data to
the contrary, it is their responsibility to present their data to peer
reviewed literature for examination.
