In my house about 2 seconds, that's my favorite.
As to split pea soup, it would probably not be good after being left out a room temperature. It's not the bacon that is the problem, but the peas themselves. Split pea soup does not keep well, even refrigerated a few days at best. I usually keep enough for one meal in the fridge and have that right away, the rest I put up in containers in the freezer for later consumption.
And believe me, you will know if it is spoiled immediately because it has a very putrid rancid smell when it has gone bad.
