Been there, Done that. Now food is trash if I've left it out over an hour. Actually, it becomes dog food. Same for any leftovers that have been in the fridge over three days. I'm probably overreacting. But I know FULL well how horrible what you went through is. I knew exactly what caused mine, as it was the only thing I ate all day.

Mine was caused by a Pizza Hut pizza. I still go there, but I really tore into them as that one and the others that I had bought before could have stayed in the oven a few minutes longer. To their credit, I have yet to by a slightly undercooked pizza from them since.
