Glove advocates beware. Universal precautions at a hospital include wearing gloves. You are required to wash your hands before putting gloves on, and after taking them off. ESPECIALLY after taking them off. You're probably okay handling your snakes and not washing in between glove changes, but if you were handling actual infectious humans, you'd be crazy to take off a pair of gloves and call that "clean."
One reference:
Gloves provide a safety barrier that protects patients or
food from skin-borne microorganisms. However, contamination
is still possible even when gloves are worn.
For example, the use of petroleum-based creams and
lotions may cause deterioration and increased permeability.
So it is essential that gloves be used in combination
with, not instead of, handwashing. In addition, it is
extremely important to wash hands after gloves are
removed, or whenever the integrity of the gloves is in doubt.
