John Golobic, of Quest Diagnostics in New Mexico, swabbed a number of beards searching for bacteria and determined that while several beards contained normal bacteria, but some contained so much poo they were comparable to toilets.
Dr Golobic said:
"I'm usually not surprised, and I was surprised by this"There would be a degree of uncleanliness that would be somewhat disturbing."
To keep these bacteria away entails constant hand washing and the use of face scrubs..
Mr Golobic added:"Try to keep your hands away from your face, as much as possible."
