Laundry and Linen Management: Infection Control in Practice

Laundry is one of the least glamorous jobs in a care home and one of the easiest to overlook when thinking about infection control — yet contaminated linen, handled or processed incorrectly, is a genuine route for spreading infection between residents and to staff. A well-run laundry process is quietly one of the more important pieces of a home's overall infection prevention system, and it deserves the same level of attention as more visible clinical procedures.

Why Laundry Is a Genuine Infection Control Risk

Used linen and clothing can be heavily contaminated with bodily fluids, and mishandling it — shaking it out, carrying it pressed against a uniform, sorting it in a resident's room rather than in a designated area — can spread infectious organisms through the air and onto surfaces well beyond where the linen originated. This risk increases sharply during an outbreak, when linen from an infected resident needs to be managed with extra care, echoing the wider precautions set out in our guide to outbreak management and norovirus infection control.

Segregation: Used, Infected and Foul Linen

Good practice separates linen into clear categories at the point it's removed: used but not visibly soiled linen, foul or infected linen (visibly contaminated with bodily fluids, or from a resident with a known infection), and linen requiring specialist handling. Each category should have its own clearly marked, colour-coded bag system, and — critically — bagging should happen at the point of removal, in the resident's room, rather than linen being carried loose through corridors or sorted later in a communal area where cross-contamination can spread further than it needed to.

Handling: The Habits That Actually Matter

The practical habits that reduce risk are straightforward but easy to let slip under time pressure: never shaking soiled linen before bagging it, since this releases contaminated particles into the air; never carrying soiled linen against a uniform; changing gloves and performing hand hygiene after handling soiled linen and before touching anything else; and never sorting or counting soiled linen in a resident's bedroom or any other resident-facing area. Bags should be securely closed before leaving the point of use, not left open for later tying.

Washing Temperatures and Process

Correct washing temperature matters for genuinely reducing microbial load, not just for getting linen visibly clean — most infection control guidance specifies a minimum wash temperature (commonly around 65°C or higher, sustained for a set period) for linen requiring disinfection, which is well above what's needed for ordinary domestic laundering. This is one of the reasons in-house laundry facilities in care homes need proper, well-maintained industrial equipment rather than domestic-grade machines, and why any outsourced laundry contractor needs to be able to demonstrate they meet the required standards, not simply assumed to.

Keeping Clean and Dirty Laundry Physically Separate

A well-designed laundry area maintains a clear one-way flow from dirty to clean, with separate, distinct areas (and ideally separate staff or at minimum strict handwashing and PPE changes between stages) for handling soiled linen and for handling and storing clean linen ready for use. Clean linen stored anywhere near the soiled-linen handling area, or handled by the same gloves without a change in between, undermines the entire point of the process.

Training Domestic and Laundry Staff Specifically

Laundry is frequently managed by domestic or ancillary staff rather than clinical staff, which means it needs its own role-specific training rather than being assumed to be covered by general infection control awareness — a point covered more broadly in our guide to infection control training for domestic and ancillary staff. Staff handling laundry need to understand not just the mechanics of the process but why each step matters, since understanding the reasoning behind a rule makes people far more likely to follow it consistently under pressure.

Frequently Asked Questions

Can a resident's soiled clothing be sorted on the spot in their bedroom? No — soiled linen should be bagged at the point of removal without sorting or shaking, and any sorting should happen later in a designated laundry area, not in resident-facing spaces.

What temperature should infected linen be washed at? Guidance typically specifies a minimum disinfection temperature well above normal domestic wash settings, sustained for a set duration — care homes should confirm their equipment or laundry contractor meets the specific standard set by current infection control guidance.

Does an outsourced laundry contractor need to meet the same standards as in-house laundry? Yes — a care home retains responsibility for ensuring any contracted laundry service meets appropriate infection control standards, and this should be checked and documented, not assumed.

Getting laundry and linen management right is an unglamorous but genuinely important part of a care home's infection control system. Learnsignal's CPD courses for care staff cover infection prevention and control across all areas of care home operations.
