I bet there's one in your freezer right now

. And you just want to know if it's ok to eat it

.
It will be ok, think about it, why does food go bad? Because bacteria manage to digest it. But since:
1) It's been in the freezer, no bacteria can live in such cold conditions.
2) I don't think bacteria go for things like popsicles

.
So eat it, and remember, they put preservatives in those things, so it should be ok for another 5 years
