  Legit that’s all you have to do. I saw a pic of some research teams findings and… yep that was enough.

  The Mythbusters did a test to see how much contamination might get onto a toothbrush in various places in a bathroom. They basically just left them in different spot for a few days and then had them tested for Fecal coliform bacteria, usually associated with the intestines of warm blooded animals. They also had a couple control brushes under a glass on a table in the middle of the shop.
  When they got the results back every single brush tested positive. Including the controls. >
  
  Wait, so what were the controls then? >
  
  Even packaged toothbrushes straight from the factory were tested and found to have fecal matter on them. >
  
  Part of the manufacturing process requires each brush to be carefully swabbed around a butthole before packaging. >
  
  The more you learn. >
  
  Close your toilet lid before you flush and stop dunking your toothbrush in your toilet
