“UH Bristol Hand Hygiene Policy- Section 5.5:
Social hand wash. Washing the hands with an un-medicated detergent and water (or water alone), to remove dirt and loose transient flora in order to prevent cross-infection. Alcohol hand rub can be used if hands are not visibly soiled.”
Loose transient flora has to be a band name. In fact there are afew diamonds in that paragraph. Just ignore capital letters, punctuation and sentence sense and you’ll see for yourself.
