We're on holiday this week. Had an Asda delivery at the start of the week. Put food into fridge then realised about 2 hours later that the fridge wasn't switched on, so I switched it on. It can't have been off foot long as ice cubes were still frozen, but it probably took at least an hour to cool down.
Will food - eg fresh chicken and quiches - be ok to eat after being out of a fridge for about three hours?!
