Refrigerated milk still expires pretty quickly. Unopened condensed milk can stay on the shelf for a good year.

[ I pick up the can and turn it around to look for a date. Nothing... Although there's no calendar I've seen in this park either, so I guess we don't really have a date to reference anyhow. I just know it was December 25th, last I remember. ]

Hmm... Well, I can probably tell if it's still good or not once I open it. I have a pretty strong stomach, too.
