TMI no pic.

I just, out of no where, had diarreah. I had some gas cramps which isn't unlike me, and all of a sudden I knew what was coming. I only went once and the cramps have gone away. I didn't eat anything out of the ordinary today. I had a peach, which I washed obviously but now I'm just scared of listeria :( I have a doc appt tomorrow so I'm gonna bring it up there. I have no other symptoms. Just looking for some reassurance :/
