A sanitizer is an agent that

  • A.eliminates every viable microorganism from a treated surface, spores included
  • B.arrests microbial growth only while it remains in contact
  • C.removes organic soil without any antimicrobial action
  • D.reduces bacterial numbers to levels judged safe by public health standards

Answer: D

Sanitization is a numbers game rather than an absolute: the count is brought down to an accepted threshold, which is the standard applied to eating utensils and dairy equipment. It neither sterilizes nor guarantees the removal of any particular pathogen.
