Personal hygiene and handwashing in commercial kitchens.
Good food-handler hygiene helps stop bacteria, viruses and allergens moving from people to food. This guide covers practical handwashing, clothing and behaviour standards, illness reporting and the 48-hour exclusion rule for diarrhoea and vomiting.
Practical guidance from TKEG (The Kitchen Efficiency Group), built around everyday UK hospitality compliance and kitchen operations.
Why does personal hygiene matter in a commercial kitchen?
People can transfer harmful bacteria, viruses and allergens to food, equipment and food-contact surfaces. Personal hygiene therefore forms part of the everyday controls that help prevent contamination in a food business.
Managers should make sure food handlers understand the hygiene standards relevant to their role and that those standards are followed in practice, not simply covered once during induction.
When should food handlers wash their hands?
Food handlers should wash their hands before preparing food and at points where contamination could otherwise be transferred. UK government guidance specifically includes after touching raw food, handling food waste or emptying a bin, cleaning, blowing the nose or touching the face or hair, touching frequently handled items such as phones, switches, door handles or cash registers, and after using the toilet.
FSA Safer Food Better Business guidance also emphasises washing before touching or handling food, especially ready-to-eat food. The important control is to wash at the point contamination risk changes rather than relying on a fixed timetable.
What does effective handwashing involve?
FSA guidance describes effective handwashing using warm running water and liquid soap, thoroughly rubbing the palms, backs of hands, between the fingers, thumbs and fingertips, then rinsing and drying thoroughly with a disposable towel.
Hand-sanitising gels can be an additional precaution, but FSA guidance says they should not replace effective handwashing. Disposable gloves are also not a substitute for clean hands and good hand hygiene.
What personal hygiene standards should kitchen staff follow?
Government guidance says staff should wear suitable, clean protective clothing. When preparing or handling food, hair should be tied back with a suitable head covering where appropriate; watches and jewellery should not be worn except a plain wedding band; and staff should avoid touching their face or hair, smoking, spitting, sneezing over food, eating or chewing gum while handling food.
Cuts and sores can create a contamination risk and should be appropriately covered. Managers should make sure suitable dressings and handwashing supplies are readily available so the expected standard is practical to follow during service.
When must illness be reported?
Food handlers must tell their manager if they are unwell. Relevant symptoms and conditions include diarrhoea, vomiting, infected wounds or sores, stomach pain, nausea, fever or jaundice, infected skin, nose or throat, and other disease that could be transmitted through food. Staff should also report if someone they live with has diarrhoea or vomiting.
A person suffering from, or carrying, a disease likely to be transmitted through food must not handle food or enter a food-handling area where there is a likelihood of direct or indirect contamination.
What is the 48-hour rule for diarrhoea and vomiting?
Food handlers with diarrhoea or vomiting must not return to food handling until they have had no symptoms for 48 hours. Government fitness-to-work guidance describes exclusion from working with or around open food normally for 48 hours from when symptoms stop naturally.
Other illnesses or infections may need different controls or longer exclusion, so managers should follow appropriate medical, public-health or environmental-health advice where required. A fitness-to-work questionnaire can help document a return-to-work assessment.
What if someone worked while they were ill?
If a member of staff has worked while suffering from an infection, areas and items they contacted should be cleaned effectively to reduce the risk of spreading infection to colleagues or customers. Management should also review what happened and whether reporting, supervision or sickness procedures need strengthening.
The aim is corrective action rather than simply recording that an incident occurred. Where food may have been contaminated, the business should assess the affected food and take appropriate action.
What hygiene records are useful?
Useful evidence can include staff induction and refresher training, illness reporting and fitness-to-work records where appropriate, corrective actions, and checks that handwashing facilities remain stocked and usable. The records should be proportionate to the business and its food-safety management system.
A certificate alone does not demonstrate that hygiene controls are being followed every day. Training, supervision, facilities and actual staff behaviour all matter.
Practical guidance, checked against official UK sources.
TKEG guidance is written for practical hospitality use. Where a topic involves regulation, official schemes or workplace safety, businesses should also consult the current guidance from the relevant authority and apply it to their own operation.

Common questions
How long must a food handler stay off after vomiting or diarrhoea?
They must not return to food handling until they have had no symptoms for 48 hours. Other illnesses may require different controls or longer exclusion.
Can hand sanitiser replace handwashing in a commercial kitchen?
No. FSA guidance says hygienic hand rubs and gels can be useful as an additional precaution but should not replace effective handwashing.
Do disposable gloves mean staff do not need to wash their hands?
No. Gloves are not an alternative to effective handwashing. Hands and glove-use practices can still transfer contamination.
Do UK food handlers have to hold a food hygiene certificate?
Government guidance says food handlers do not have to hold a food hygiene certificate, but businesses must be able to show staff have the right skills and up-to-date training for their role.
Should food-handler illness be recorded?
A proportionate illness-reporting and fitness-to-work process can help managers make safe decisions and evidence the action taken, particularly where a food handler has symptoms that could affect food safety.
