When in doubt, throw it out, it's not worth the risk. The general rule of thumb is to never let cooked food stay at room temperature longer than 2 hours, (even less time for some raw foods). Since the casserole would have thawed long before the 11 hours were up, it would not be safe to take the chance on eating it.
Thousands upon thousands of people become seriously ill from food borne bacteria every year, some of which die. So never take that risk.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
