We just had a power outage for about 5-6 hours (I'm not sure exactly how long as I left the house and returned to find the power restored) and I'm a bit concerned about the food in the fridge/freezer.
My housemate opened the fridge and freezer doors once in that time for a stickybeak though I promptly told him to shut them back up immediately.
I had a chat with some nice bloke from the power company who said food in newer fridges "should" be okay for 6 hours, but our fridge and freezer (he didn't comment on the freezer) would certainly not be described as new. Interestingly, he also said that I can claim compensation on anything that is spoiled.
Would you toss everything in this situation?
I have a lot of leftovers I'd just made for the week that I would be pretty sad to see go.
I wouldn't throw everything out. Best thing would be to exercise common sense and go through each item in the fridge.
Put it this way - if you bought something from the supermarket and kept it in a car for 2-3 hours, would it be safe to consume? Would you eat it?
Apply this test to everything, especially opened foods, and you can't go wrong.
