Consumers may soon be able to go for longer between milk-buying trips. That's because Brazilian company Agrindus hopes to start marketing plastic milk bottles that use embedded silver nanoparticles to kill bacteria. Grade A pasteurized fresh whole milk packaged in those bottles can reportedly last for up to 15 days, as opposed to the usual seven.
The technology was developed by partner company Nanox, and involves first coating silica ceramic particles with silver nanoparticles. This reportedly has a synergistic effect, with the silica boosting the antimicrobial properties of the silver.
Those coated particles take the form of a powder that is subsequently mixed into liquid polyethylene. Using blow- or injection-molding, that plastic is then made into bottles which Agrindus plans to sell to dairy goods companies. The particles can also be used to make milk bags, which should extend shelf life from four to 10 days.

um... I think in general it's a good idea to keep heavy metals away. At least, there were at least a couple of episodes of House MD where the patient was gonna die due to heavy metal poisoning (including the memorable one about the dude dying of gold poisoning).
also, see wiki link to argyria that people posted above.

A fictional TV show should never be used to support your position on anything (except culture).
