Depending on where you get your pork, freezing might not be necessary.
I'm in the NW US, and often feed pork straight from the grocery store.
Wild pork or boar, I would freeze, but I don't worry about the farm raised hogs.
Fish that I buy is normally either still frozen solid or "previously frozen"... so I don't normally worry about it, either (again, grocery store fish for human consumption, too). NW Pacific salmon scares me, so Denna only gets cooked leftovers from our plates for salmon....
