We have hand-sanitizer for all the Extraordinary Ministers of Holy Communion to use before handling the Blessed Sacrament.
If the cup is served properly it can all be sanitary. The pruificator needs to drape from the hand of the EMHC, and after each sip a new portation of the purficator is used, the cup is rotate 1/4 for every recipient.
New space on the purificator, new space on the cup each time. I’ve had to stop and refold the pruficator.
Hand sanitizers are no guarantee of anything.
Some of them have actually contained bacteria.
