I had a similar, though better informed, experience with escolar. My wife and I were planning on having a nice anniversary dinner at an upscale restaurant in Austin, TX. Escolar was on their online menu, and I read up on it. The Wikipedia article is very precise in its description of its symptoms, and that it's banned in other countries. I thought, bah, it can't really do that to you...can it? It was one of two options on their prixe fixe menu, and I can cook a good steak myself, so it's what I ordered. After dinner, we walked a couple blocks over to a bar off 6th Street. As the lady at the door was going to take our cover charge, I suddenly felt like my bowels were going to violently void themselves. We ducked out of line and hurried back to the hotel. I made it just in time, and had one of the most unpleasant experiences I've ever had on a toilet. The symptom descriptions were very accurate.
