CDC / HICPAC Guidelines:
Laundry and Bedding
From the “Guidelines for Environmental
Infection Control in Health-Care Facilities”
(2003):
Epidemiology and General Aspects of
Infection Control
Collecting, Transporting, and Sorting
Contaminated Textiles and Fabrics
Parameters of the Laundry Process
Special Laundry Situations
Surgical Gowns, Drapes, and Disposable
Fabrics
Antimicrobial-Impregnated Articles and
Consumer Items Bearing
Antimicrobial Labeling
Standard Mattresses, Pillows, and AirFluidized Beds
Laundry and Infectious Diseases
● Textiles contaminated with body substances
can contain large numbers of
microorganisms (106 – 108 cfu/100 cm2 fabric)
● Few reports in the literature link laundry to
disease transmission when proper
procedures are followed
● Annual estimates for volume of laundry
processed in U.S. health care: 5 billion lbs.
(1980s, early 1990s estimate; now?)
● Continue current infection prevention
practices
Current Healthcare Laundry
Standard in the U.S.
● Standard: Hygienically clean
● Not quantified for microorganisms, but assume
textiles are generally rendered free of vegetative
pathogens
● Through a combination of soil removal, pathogen
removal, pathogen inactivation, contaminated
textiles are rendered hygienically clean
● Carries negligible risk to healthcare workers and
patients, providing that the clean textiles are not
inadvertently contaminated before use
Main Steps of Healthcare
Laundry Processing
• Collection of soiled textiles at point of use
• Transport to laundry
• Wash cycle:
– Flush, main wash, bleaching, rinsing, souring
• Dried and pressed
• Packaged, loaded into carts
• Delivery back to the hospital
Laundry Operations
● If using hot water washing, water temperature
>71° C (>160° F) is needed
● Some healthcare facilities may not have access to
water at this temperature
● Chlorine bleach (50 – 150 ppm) is effective
laundry additive, especially in hot water
● One of the rinses includes a mild acid (sour) to
neutralize residual alkalinity from the wash
● Helps to inactivate microorganisms
● Reduces risk of skin reaction to alkali
Alternatives to Hot-water
Laundry
● In-house laundries consume an average of 50%
- 70% of the facility’s hot water (10% - 15% of
the total energy used)
● Water temperature may be regulated
● Lower temperature wash cycles can be used
with appropriate detergents and laundry
additives
● New detergents and processes (e.g., oxidative
products) need study
Laundry Transport /
Storage
• Separate clean textiles from contaminated textiles
when transporting in a vehicle
• Physical barriers and/or space separation
• Clean, unwrapped textiles can be stored in a clean
location for short periods of time
• Unwrapped textiles should be stored so to prevent
inadvertent contamination by soil or body
substances
• This is the part of the overall process that is
most vulnerable to outside contamination
The Healthcare Laundry

Healthcare Laundry Accreditation Council
HLAC Accreditation
• HLAC Standard developed from both laundry
operations and infection prevention expertise
• Inspection process assesses compliance with
the Standard
• Accreditation is voluntary
• Renewal every 3 years is necessary to maintain
accreditation
• Healthcare professionals increasingly aware of
this accreditation program
Preamble: This portion of the 2011
Standard is more comprehensive
and informative compared to the
Introduction and Background in the
2006 Standard:
Introduction
Important
Terminology
States the purpose of the Standards: minimum
acceptable healthcare laundry practices
Defines Universal Precautions; identifies key
participants – provider, customer, end user, inspector
Interpretive
Guidance
Defines the scoring level associated with each
statement’s verb – must, shall, should, may
Disclaimer
Focuses on and clarifies the role of the inspector
Standards: This portion of the 2011 Standard is
expanded extensively in an outline format, with a
step-by-step, systematic approach for processing
healthcare textiles in an efficient and safe
environment to produce a hygienically clean textile
product for patient care.
Content Improvements
Format
Each Standard statement has a unique number and addresses a single point, not
multiple items which previously created scoring problems
Content
Comprehensive and detailed; addresses laundry processes, equipment, functional
separation, quality assurance, worker safety, working environmental issues; minor
reorganization of topics in Parts I and II; the new Standards raise the bar for laundry
processes and product for healthcare textile reprocessing
Verbs
Citations
Greater clarification – scorable statements are clearly identified, and “must” statements
are presented in bold-face type
Scorable statements include citations to support the statement where available,
including government regulations, professional association standards, and peerreviewed literature evidence
Message: Compliance with the new 2011 HLAC Standards will result in patient-focused infection prevention,
enhanced infection control and patient safety through the production of a hygienically clean textile product. This
benefits you – the provider, your customer, but most importantly the patients in your customer’s healthcare facility!

Mucormycosis
Outbreak
and
Hospital Textiles
Mucormycetes
• Mucormycetes are ubiquitous molds
• 23 pathogenic species; Genus Rhizopus
causes half of all infections
• Rhizopus oryzae most common; genetic
variety observed within species
• Mucormycosis:
– Skin is common site of infection
– Invasive mold: fatality rate highly
variable (ranges from 10% - 94%)
Additional Results
• Patient specimens:
– Type: culture (1), tissue block (3)
– All four (+) for Rhizopus oryzae
• Environmental cultures:
– Hospital A: 13/13 cultures (+) for
Rhizopus oryzae
– Laundry facility: No Rhizopus oryzae
– R. oryzae from one patient and from
clean linen/cart had the same genetic
subtype
Conclusions
• Hospital linens were the most likely vehicle to
have brought Rhizopus in contact with the
patients
• Genetic subtyping of fungal isolates supported
this epidemiologic hypothesis
• Contamination of clean linens with Rhizopus
happened repeatedly, but might have been
intermittent
• Hospital linens should be laundered, shipped,
and stored in a manner that minimizes
exposure to environmental contaminants
Things to Consider
• Some have called for purposeful
sanitization of laundry because of the
outbreak
– Laundering process was not implicated
• Some are advocating treating textiles to
leave antimicrobial chemicals as residue
– Do we know how safe this is for patients?
– EPA may consider this as a “treated article”
Chain of Infection (COI)
● Virulent pathogen:
● Bacteria, fungi, viruses, parasites,
prions
● Sufficient number of pathogen:
● Infectious dose
● Mode of transmission:
● Contact, droplet, airborne
● Portal of entry:
● Broken skin, mucous membrane,
respiratory tract, ingestion
● Susceptible host:
● Age, immunity, medical conditions
Other possible links include reservoir,
portal of exit
What is the Evidence to Justify
Purposeful Sanitization?
• Outbreaks of infection associated with
clean healthcare textiles still a rare event
• Europeans have promoted laundry
disinfection
– More active in laundry disinfection research
• Is laundry disinfection a cost-effective
process?
Why is This Significant?
● Hospital environmental and medical equipment
surfaces rapidly become contaminated
● Recent studies demonstrate that:
● Hands and gloves of healthcare workers readily
acquire pathogens after contact with
contaminated surfaces
● Healthcare workers can transfer these pathogens
to subsequently touched patients and inanimate
surfaces
● Patients subsequently can become
colonized/infected
Basic Strategy Elements for Preventing
and Eliminating Contamination
of Environmental Surfaces

Prevent environmental surface contamination




Handwashing / hand hygiene
Use of barrier coverings on clinical touch surfaces
Responsible use of gloves, personal protective equipment (PPE)
Clean–to–dirty work flow whenever practical
• Avoid dirty-to-clean work flow as much as practical

Remove environmental surface contamination
 Cleaning

Inactivate environmental surface contamination
 Disinfection for inanimate surfaces
 Antisepsis for living tissue
HACCP for Laundry
• Hazard Analysis and Critical Control Point
• Similar to the ICRA currently used in
hospital infection prevention program
• Assess all aspects of the laundering
process to identify opportunities for
contamination to occur
• Owner/operators become proactive in
infection prevention
Textile Management and
C. difficile Contamination
● Consider cohorting symptomatic patients/ residents’
clothing to wash separately from clothing of healthy
residents
● During a wash cycle, do not mingle used cleaning cloths
in with clothing from healthy residents
● High numbers of spores may remain on the cloths if
used with a non-sporicidal disinfectant
● Use of sporicidal disinfectant will reduce the viable
spore number

Epidemiology Conference, poster #160
Making the Case for Laundry
Standards Revisions
• Demonstrate added value for product quality,
patient safety, healthcare worker safety
• Research new developments using validated
methods to assess antimicrobial properties
• Make the case for change to your healthcare
customers
– Publish in peer-reviewed journals
– Continue reporting new developments in industry
publications, but explore publication venues typically
used by nurses, EVS directors, hospital
epidemiologists
