As far as I recall Ag+ ions can block sodium channels in bacterial
membranes. Higher concentrations, of course, could interact with thiol
groups of proteins.

It was used to purify water in Moscow for more than 20 years (late 1880s -
early 1910s).

Never heard of any (other than the Bolshevick revolution :-) Are you
saying silverware is dangerous?
