The water starts out as sanitary drinking ice (if it wasn't, they could not have it in contact with food). But it doesn't stay sanitary since it is in contact with the outside of containers and people's hands as they reach in and take the food out.katytrott said:I had read somewhere that you should not take the ice, that is surrounding cold food stuff in the buffet meals etc, to add in your own water bottles. According to this cast member, the water that is used for this ice is not drinking water and is not sanitary.
