I know. Stupid question. The official answer is "two hours". But... that answer is even given for "how long can fresh whole eggs be unrefrigerated and still safe to use", and... THAT answer in real life is a lot more than two hours. Fluid milk... is definitely unsafe after 2 hours. So... I made pizza today. Super-extra-dry sausage, fresh veggies, cheese, spices, freshly homemade crust. Had lunch, ate half. Left the left-overs cooling on the table. Day got busy, and I forgot to put them in the fridge before we left for the afternoon. They are in the fridge now... were out about 4 hours in a coolish house (it's still winter here, house is about 72 during the day) Safe to eat? or not?
