What Causes Explosive Diarrhea?

I don t remember eating anything that was spoiled to cause me to have diarrhea. Yesterday I worked 11 hours and only ate steak. It was cooked all the way and thawed in the fridge. But I also had a huge can of Red Bull to try to keep me going for work and I don t know if that can cause me to have explosive diarrhea. Any answers?
