What EPA-registered hospital detergents and disinfectants are available for use in patient-care areas?

EPA-Registered Hospital Detergents/Disinfectants for Patient-Care Areas

Use EPA-registered hospital detergent/disinfectants for routine cleaning and disinfection of environmental surfaces in patient-care areas, particularly when uncertainty exists about the nature of contamination or presence of multidrug-resistant organisms 1.

Categories of EPA-Registered Products

The CDC/HICPAC guidelines specify several categories of EPA-registered hospital disinfectants based on clinical need:

For General Patient-Care Areas

• EPA-registered hospital detergent/disinfectants are recommended for one-step cleaning and disinfection of housekeeping surfaces where blood, body fluid contamination, or multidrug-resistant organisms may be present 1
• These products combine cleaning and disinfecting properties, eliminating the need for separate steps

For Immunocompromised Patient Areas

• EPA-registered hospital detergent/disinfectants should be used for daily wet-dusting of horizontal surfaces in areas housing immunocompromised patients (e.g., HSCT patients) 1
• Moisten cloths with small amounts of these products rather than using dry dusting methods that disperse particles

For Operating Rooms

• EPA-registered hospital disinfectants must be used with single-use mops for wet vacuuming or mopping OR floors after the last surgical procedure of each day 1

For Blood and Body Fluid Spills

• EPA-registered germicides labeled as tuberculocidal OR products on EPA Lists D and E (with specific HIV or HBV claims) are required for decontaminating blood and body fluid spills 1
• Sodium hypochlorite products (bleach-based) are preferred:
  • Use 1:100 dilution (500-615 ppm available chlorine) for routine blood spills on nonporous surfaces 1
  • Use 1:10 dilution (5,000-6,150 ppm available chlorine) for large blood spills or laboratory culture spills 1

For Specific Pathogens

Clostridium difficile:

• No EPA-registered products are specifically labeled for C. difficile spores 1
• Use hypochlorite-based products in areas with ongoing C. difficile transmission based on surveillance data 1

VRE and Other MDROs:

• Standard EPA-registered disinfectants used according to manufacturer's instructions are appropriate 1

Key Implementation Points

Application Requirements

• Follow manufacturer's instructions for concentration, contact time, and safety precautions 1
• Prepare fresh cleaning solutions daily or as needed 1
• Replace solutions frequently per facility policy 1

Critical Safety Considerations

What NOT to use:

• Never use high-level disinfectants (liquid chemical sterilants) on environmental surfaces - these are toxic and inconsistent with label instructions 1
• Do not use alcohol for large environmental surface disinfection 1
• Avoid phenolics in neonatal units for disinfecting bassinets or incubators during infant occupancy 1

For neonatal areas:

• If phenolics must be used, prepare to correct concentrations per manufacturer's instructions 1
• Always rinse phenolic-treated surfaces with water 1

Common Pitfalls to Avoid

1. Using products without EPA registration - Only EPA-registered hospital disinfectants meet federal requirements for healthcare use
2. Incorrect dilution - Improper concentrations reduce efficacy or increase toxicity
3. Inadequate contact time - Surfaces must remain wet for the manufacturer's specified contact time
4. Mixing cleaning with disinfection inappropriately - Clean visible soil first, then apply disinfectant
5. Using disinfectants in non-patient areas - Detergent and water suffice for administrative offices 1

The evidence strongly supports using EPA-registered products as the regulatory standard for hospital environmental disinfection, with specific product selection based on the pathogen, surface type, and patient population being served.
