Silicone molds

[Shiri]

Do I need to have separate silicone molds for meat and dairy ?

If yes, what do I do with molds (like the attached pic) that were use for making chocolate/ candy (dairy) and also to freeze chicken broth that was lukewarm? (With several weeks in between uses)

And would I need to dispose of the chicken broth that was put into those molds?

Should have separate for meat and milk.
You can just designate it now for meat or milk. No koshering needed. The food that was already placed inside it fine to eat.
