Yes and No, germs are in the air, and usually our hands contact with soap dispensers when they are dirty. So the germs that are on our hands often get transmitted to the soap dispenser when we touch it. Usually this isn't a big deal, because a dollop of soap is dispensed into our hands right after touching the dispenser, but not everyone follows proper hand washing procedures. If the dispenser is not adequately cleaned and sanitized often enough, a biofilm can form, which is a breeding ground for microbials that requires a particularly thorough cleaning to remove.
