Can meat and cheese be stored together?
Summer sausage is cooked in the smoking process, and fermented, which kills bacteria and gives it a long fridge life.  Some summer sausages don't even require refrigeration until opened! Wet, raw sausage, on the other hand, is asking for trouble. 

I'm sure your husband will forgive your fussiness when you bring him kielbasa and a nice chunk of aged cheddar, open in the same container, and ready to munch!
