Sterility of a processed load is expressed as

  • A.the concentration of disinfectant used
  • B.a probability that a viable organism remains
  • C.a certainty that nothing survives
  • D.the number of organisms present before processing

Answer: B

Because inactivation is logarithmic, no finite process can prove that nothing survives; the accepted standard is a sterility assurance level, conventionally a one in a million chance of a survivor. That follows directly from the meaning of the D-value.
