Quick answer
Kitchen hygiene is not an end-of-night clean: it's a method you manage hour by hour, across surfaces, equipment, food and people. It rests on four pillars: cleaning and sanitising, temperature control, cross-contamination prevention and personal hygiene. A written checklist, split by frequency, turns the method into routine and protects both you and your customers.
Why you need a checklist, not good intentions
In a brigade under pressure, memory is not enough. When fifty covers land at once, the first thing to slip is the invisible gesture: changing the cloth, sanitising the board, logging the fridge temperature. A checklist exists precisely for this: to make mandatory what stress would otherwise push to later.
A good checklist is split by frequency (per task, end of service, daily, weekly, monthly) and assigns an owner to every line. Without a name next to the task, the task belongs to no one. Pin it where the work happens, not in a binder in the office.
The four pillars of kitchen hygiene
1. Cleaning and sanitising
These are two distinct steps, not synonyms. Cleaning removes residue and visible dirt with detergent. Sanitising cuts the microbial load with a disinfectant, and only works on an already-clean surface: grease acts as a shield for bacteria. The correct sequence is always: pre-clean, detergent, rinse, disinfectant, contact time, final rinse, dry.
2. Temperature control
Most bacteria multiply in the "danger zone" between 5 and 60C. All temperature work exists to move food through that band as fast as possible.
| Stage | Temperature | Notes | |-------|-------------|-------| | Fridge | 0-4C | Meat, fish, dairy | | Freezer | -18C or below | Verify with a probe thermometer | | Core cooking | min. 75C | Poultry and minced meat always | | Hot holding | above 60C | Never below on the pass | | Rapid cooling | 60C to 10C in 2 hours | Blast chiller or small portions |
3. Cross-contamination prevention
The most underrated risk. Raw and cooked must never touch: separate boards, knives, containers and work zones. The colour-coded board system (red meat, blue fish, green vegetables, yellow cooked, white dairy) removes the error at the root. In the fridge, cooked goes on top, raw below: that way a drip cannot contaminate what is already ready to serve.
4. Personal hygiene
Hands are the main vehicle of contamination. Wash them at the start of the shift, after every break, after touching face or hair, after handling waste and at each change of task. Short nails with no polish, no jewellery, hair tied back, a clean uniform changed every day. Anyone with gastrointestinal symptoms or unprotected cuts does not work the line.
The operational checklist by frequency
This is the structure you can adapt to your own kitchen.
| Frequency | Activity | Owner | |-----------|----------|-------| | Per task | Hand wash, change board/knife, sanitise surface | Chef de partie | | End of service | Clean surfaces, ranges, equipment, wash cloths | Brigade | | Daily | Full surface sanitise, empty waste, log fridge temperatures | Section head | | Weekly | Deep-clean fridges, hoods, drains, shelving | Sous chef | | Monthly | Defrost freezers, check seals, calibrate thermometers | Sous chef |
Worked example: disinfectant contact time
A frequent mistake is to spray the disinfectant and immediately wipe it off. Most professional products require a contact time stated on the label, usually between 1 and 5 minutes. If the product needs 5 minutes and you wipe after 30 seconds, you have cut its effectiveness by over 90%. Rule of thumb: spray, leave it the stated time, then rinse or wipe. Time it; do not guess.
Hand sanitising, step by step
An effective hand wash lasts at least 20 seconds, not the 3 seconds a busy line tends to allow. Wet, lather, scrub palms, backs, between the fingers and under the nails, rinse and dry with single-use paper. Shared cloth towels and air dryers should be avoided on the line: the first re-contaminates, the second is slow. An alcohol-gel dispenser on the pass helps between tasks, but never replaces a wash when hands are visibly soiled.
Storage and raw-material handling
Hygiene starts at goods-in. Check the supplier's temperature on delivery, reject damaged packaging, verify dates. In storage, apply FIFO (first in, first out): what comes in first goes out first. Label every container with contents and the date opened or produced. Never leave food open without a lid or film, and never on the floor: everything on shelves at least 15 cm above ground.
Common mistakes
- Sanitising without cleaning first. Disinfectant on a dirty surface does not work: grease protects the bacteria.
- Wiping straight after the disinfectant. This cancels the contact time and the product's action.
- One board for raw and cooked. The number-one cause of cross-contamination.
- Filling temperature logs in at the end of the week. An inspector spots this instantly and treats them as missing.
- Cloths used for hours. A damp dirty cloth is a culture broth: change them often and wash hot.
- An overpacked fridge. Air cannot circulate, the temperature rises and is uneven.
- Polish, false nails and jewellery on the line. Foreign bodies and bacteria traps.
