Food handlers should wash hands with warm water and soap for at least 20 seconds, covering palms, backs of hands, between fingers, thumbs and nails, then dry with a single-use towel. Wash before handling food, after raw food, after the toilet, and after touching your face, waste or cleaning chemicals.
Why handwashing matters most
Key takeaway: Handwashing for food handlers is one of the simplest controls for stopping bacteria, viruses and allergens from spreading onto food.
Food handlers use their hands constantly: opening fridges, preparing raw ingredients, touching utensils, handling packaging, wiping surfaces and serving ready-to-eat food. That makes hands one of the most common routes for contamination in a food business.
Regulation (EC) No 852/2004 requires food businesses to maintain hygiene controls, including personal hygiene requirements for people working in food-handling areas. It also requires food handlers to be supervised, instructed and/or trained in food hygiene matters appropriate to their work activity.
In practice, good hand hygiene helps prevent:
-
Bacteria from raw meat, poultry, fish and eggs spreading to ready-to-eat food
-
Viruses such as norovirus being transferred after poor toilet hygiene
-
Dirt, grease, allergens or cleaning chemicals being carried between tasks
-
Contamination from touching the face, hair, mobile phones, money, bins or dirty cloths
A useful rule is simple: if your hands could have picked up contamination, wash them before touching food, equipment or clean surfaces again. In the kitchens we audit, the weakest point is rarely “no sink exists”; it is usually that people rush between tasks and miss the moment when handwashing is needed.
The step-by-step method
Key takeaway: Effective handwashing is not just a quick rinse; it is a deliberate method that cleans every surface of the hands.
The proper method for handwashing in food safety should cover the whole hand, not only the palms. The Food Safety Authority of Ireland advises washing for at least 20 seconds, using warm running water, enough soap to form a lather, thorough rubbing of all hand surfaces, rinsing and complete drying.
Use this step-by-step method:
-
Wet your hands under warm running water.
-
Water helps loosen dirt and allows soap to spread across the skin.
-
Apply enough soap to make a good lather.
-
Ordinary liquid soap is usually sufficient where hands are washed properly; antibacterial soap is not normally required.
-
Rub palm to palm.
-
Start with the largest surfaces, but do not stop there.
-
Clean the backs of both hands.
-
Rub the back of one hand with the palm of the other, then switch hands.
-
Clean between fingers.
-
Interlace fingers and rub carefully. Food residue and moisture often remain between fingers.
-
Clean thumbs and fingertips.
-
Rotate each thumb in the opposite palm, then rub fingertips and nails against the palm.
-
Rinse thoroughly under running water.
-
Rinsing removes loosened dirt, soap and microorganisms.
-
Dry thoroughly with a hygienic method.
-
Use a single-use towel or another suitable method provided by the business. Wet hands spread microorganisms more easily than dry hands.
-
Avoid recontaminating your hands.
-
Where needed, use a disposable towel to turn off a manual tap or open the door.

When you must wash your hands
Key takeaway: Food handlers must wash hands at task changes, contamination points and before handling clean or ready-to-eat food.
Food handlers should wash hands as often as necessary. The key is not a fixed number of times per shift; it is washing at the right moments. Official food-safety guidance lists critical moments including before work, before handling cooked or ready-to-eat food, after raw food, after waste, after cleaning, after using the toilet, after coughing or sneezing, and after eating, drinking or smoking.
Wash your hands:
-
Before starting food handling work
-
Before preparing or serving ready-to-eat food
-
Before putting on disposable gloves
-
Between raw and ready-to-eat food tasks
-
After handling raw meat, poultry, fish, shellfish or eggs
-
After using the toilet
-
After coughing, sneezing or blowing your nose
-
After touching your face, hair, skin, wounds or plasters
-
After handling waste, bins or dirty packaging
-
After cleaning tasks or handling cleaning chemicals
-
After touching money, phones, tablets, door handles or delivery equipment
-
After eating, drinking, smoking or vaping
-
After removing gloves
-
Whenever hands look or feel dirty
Country variations
EU food hygiene rules create the baseline, but Member States and local authorities may apply additional expectations through national guidance, inspection practice or sector-specific rules. Training certificates, inspection documentation and workplace procedures may therefore vary by country. This article gives EU-wide food hygiene guidance, not legal advice.
Soap, water and drying
Key takeaway: Soap, running water and proper drying matter more than a token rinse under the tap.
Handwashing works because soap and rubbing lift contamination from the skin, water rinses it away, and drying reduces the transfer of microorganisms. The technique is more important than making the water painfully hot. Water should be comfortable enough that the food handler can wash thoroughly without rushing.
Food businesses should provide suitable handwashing facilities that are accessible, supplied and maintained. A handwashing point should not be blocked by stock, used as a dumping area or confused with a sink for washing equipment. The moment a handwash sink becomes inconvenient, shortcuts begin — and shortcuts are not a hygiene system; they are a complaint waiting politely in the corner.
Good handwashing facilities normally include:
-
Running water
-
Liquid soap in a dispenser
-
A hygienic drying method, such as single-use towels
-
A nearby waste bin where towels are used
-
Clear separation from sinks used for food or equipment washing
-
Signage or reminders where useful
-
Regular checks during service
Hand sanitiser can support hygiene in some settings, but it is not a replacement for washing visibly dirty, greasy or food-contaminated hands. Alcohol-based products are less reliable when hands are physically dirty or covered with organic matter. FSAI guidance notes that alcohol hand disinfectants and antiseptic wipes are only effective on physically clean hands.
Gloves are not a substitute
Key takeaway: Gloves can reduce direct contact with food, but dirty gloves spread contamination just like dirty hands.
Gloves often look hygienic, but they can create a false sense of safety. A food handler wearing the same gloves while handling raw food, touching a bin, using a till and preparing ready-to-eat food is not controlling contamination. They are simply moving it around in a more theatrical costume.
Gloves should be used only where they support the task and are changed correctly. Food handlers should wash hands before putting gloves on, between glove changes and after removing gloves. FSAI guidance also confirms that gloves are not a legal requirement for handling food and that bare-hand contact can be acceptable where proper handwashing procedures are in place.
Use gloves carefully:
|
Situation |
Correct action |
|
Before putting gloves on |
Wash and dry hands first |
|
Gloves become torn |
Remove, wash hands and replace |
|
Moving from raw to ready-to-eat food |
Remove gloves, wash hands, put on clean gloves if needed |
|
Handling money, bins or cleaning items |
Change gloves before returning to food tasks |
|
Removing gloves |
Wash hands afterwards |

Common mistakes
Key takeaway: Most handwashing failures are small behaviour failures repeated during busy service.
Poor handwashing is usually not dramatic. It is rushed, inconsistent and easy to miss during a busy shift. Managers and supervisors should observe actual behaviour, not just assume that a sink and a poster are enough.
Common mistakes include:
-
Rinsing hands without soap
-
Washing for only a few seconds
-
Missing thumbs, fingertips and between fingers
-
Drying hands on an apron, cloth or uniform
-
Touching a dirty tap, handle or phone immediately after washing
-
Washing only after raw food, not before ready-to-eat food
-
Wearing gloves too long
-
Using hand sanitiser instead of washing dirty hands
-
Blocking the handwash sink with containers or utensils
-
Forgetting to wash after waste, cleaning or money handling
A practical supervisor check
Use this short observation check during a shift:
-
Are handwash sinks accessible and supplied?
-
Are food handlers washing at task changes?
-
Are hands dried hygienically?
-
Are gloves changed when tasks change?
-
Are phones, money and bins treated as contamination points?
-
Are new or temporary workers following the same standard?
-
Are corrective reminders calm, immediate and documented where needed?
Hand hygiene should be trained, observed and reinforced. A policy that lives only in a folder is not a control. A repeated habit at the sink is.

Build safe hand hygiene habits with Basic Food Hygiene training
Handwashing is a basic control, but it only works when food handlers understand when, why and how to do it. The Basic Food Hygiene for Food Handlers course helps learners build practical habits for handwashing, personal hygiene, safe food handling and contamination prevention.
