That all sounds like a bit over the top to me! With glazed ceramics you really don't need to worry, you could give them a spray with some disinfectant then just wash as you would any cup (for yourself or the hams) if giving it back to the ham then I would suggest giving a thorough rinse by hand to remove any residues left from washing.
It's only porous things or natural materials like wood/coconuts etc you would need to be concerned about removing any bacteria or scent.
