I’ve actually wondered about this. If you take a sealed container, freeze and thaw it again, shouldn’t it be sterile? So basically good for as long as the seal remains tight?
With some exceptions of course, the seal might not be tight at low temperatures, some bacteria can survive frost etc.

freezing does not kill most bacteria and molds, just halts them
