While it is still a very annoying bug with the food spoiling, there is a minor fix to it done in game.  It's still extremely annoying because you have to remember to do it every time you see a Load Screen.   This includes starting the game, as well as going on adventures (including the fridges at location once you buy a lot.)

The simple fix it, as soon as you are finished loading, go into buy mode, open the household inventory, move your fridge into the household inventory, then place it back on the lot.  The bug should be squashed until the next time you use a load screen.
