So far our situation has been easy on this question as the temps never went above 30 and after the storm passed the temps plunged down even further. Holding at 4 degrees right now day four without power. In fact we have had the opposite problem in that a lot of the fridge stuff that we didn't eat up already - like the lettuce - has frozen solid & will have to be tossed. Of course the the meat is so expensive that I'm glad that has been our problem.
