factors to consider in selecting alternative technologies
Factors to Consider in Selecting Alternative Technologies
  • Microbial Inactivation Efficacy
    • Minimum: Level III Disinfection
      • Inactivation of vegetative bacteria, fungi, lipophilic/hydrophilic viruses, parasites, and mycobacteria at a 6 Log 10 reduction or greater; and
      • Inactivation of B. stearothermophilus spores and B. subtilis spores at a 4 Log 10 reduction or greater
    • Biological Indicators:
      • 6 Log 10 reduction of Mycobacterium phlei and Mycobacterium bovis (BCG) (ATCC 35743)
      • 4 Log 10 reduction of B. stearothermophilus (ATCC 7953) and B. subtilis (ATCC 19659)
