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.

I think milk is one of the better products in terms of shelf life already. On the other hand I'd not like to introduce any more nanoparticles to my system... While silver itself seems quite benign, everybody and their dog know that once you go nano, all bets are off.

If you drink silver in your milk, does it make you taste bad when the strigoi drink you?

I may have found a way to defend myself against vampires:
Drink milk laced with silver nanoparticles. The nanoparticles become part of my body and when a vampire touches me (for drinking my blood), he burns to death in a quick fireball. The rest of his kind run away.

Good plan, basically, but keep in mind that it would not affect vampires but werewolves instead.

Depends on what mythology the vampire hails from.

Oh, great! I've got a house on an island in the middle of a river. I have garlic, hawthorn, pineapples, AND screwpine growing all over the place. I have so many holy symbols painted on the building it looks like graffiti and after I added the Buddhist ones people thought I was a Nazi. And don't get me started on the police complaints after I started leaving emergency stakes and machetes around the property, especially since I have to keep polishing the machetes to a mirror finish.
Now you're saying I ALSO have to drink silver if I want to keep vampires away. I'll start to look like a smurf, do you realize how DUMB that will look?

so dress in some spandex, and tell them you are the tick, they will completely understand, and pay for your next hotel visit where you can socialize with many people who are just like you.

Please note that Argyria is mostly harmless. It's mostly just cosmetic, but it is currently irreversible.

So, if you're incorporating silver into your tissues to this extent, does it render you more impervious to projectiles or radiation?

I'm assuming, that you'd be dead long before you got enough silver in your body to markedly increase either. The only reason Wolverine didn't die is, because he was already a "Super Hero" with crazy regeneration. I assume at some point ingestion of silver or gold would result in "Heavy Metal Poisoning". The difference is that it would either take a lot more or you are much less likely to get enough of either than you are with something like lead.

Too bad the industry will ensure labelling laws don't require them to notify you of the contents, so like GM foods, you'll never know what your ingesting. Until it's too late, and we discover all kinds of detrimental health issues that can be traced back to "silver poisoning." But hey, just so long as nothing gets in the way of commerce, all praise our corporate overlords and their duly elected government lackeys.

It isn't benign. There's a bunch of wingnuts out in the West that have drunk themselves a permanently blue skin with silver particles.
