Thank you for the query.
usually do not causes infection to the healthy digestive system. As healthy intestines are colonized by protective bacterias which do not allow to grow any other bacterias. That is why Clostridium difficile has no chance to infect intestines. It has such chance after antibiotics therapy (which decreases amount of "good" intestines bacterias) or during immune deficiency
So there is nothing you should worry about. Especially that you have washed your hands.
Hope it will help.
