Good food hygiene comes down to a handful of rules applied on every shift. This is the plain-English list of food hygiene rules for food handlers in Ireland - the habits an EHO expects to see and that a food hygiene course trains into your team. Print it, pin it up, and make it second nature.
The 4 Cs of food hygiene
- Cleaning - clean as you go; follow a cleaning schedule; sanitise food-contact surfaces.
- Cooking - cook to safe core temperatures (e.g. 75°C for poultry).
- Chilling - keep cold food at 5°C or below; cool cooked food fast.
- Cross-contamination - separate raw and ready-to-eat. See the controls.
Personal hygiene rules
- Wash hands thoroughly and often - after the toilet, handling raw food, breaks and waste. See the hand hygiene SOP.
- Wear clean uniform; tie back hair; remove jewellery.
- Cover cuts with a blue waterproof dressing.
- Do not handle food when unwell with vomiting or diarrhoea - report it.
Temperature rules
Know the danger zone (5°C-63°C), check fridges and probe food, and log readings. Hot-hold at 63°C or above; reheat to 75°C.
Allergen rules
Know the 14 EU-listed allergens, give accurate allergen information, and prevent cross-contact. This is a legal duty under EU 1169/2011.
Storage and waste rules
Use FIFO stock rotation, store raw below ready-to-eat, date-label, and remove waste regularly to deny pests food.
How to wash your hands properly
Hand-washing is the single most effective food hygiene control, and it is done badly more often than any other. The correct method takes about 20 seconds:
- Wet hands with warm running water.
- Apply soap and lather palms, backs, between fingers and thumbs.
- Scrub for at least 20 seconds, including under nails.
- Rinse thoroughly under running water.
- Dry with a clean paper towel - never a shared cloth.
Wash after the toilet, after handling raw food, after breaks, after touching your face or hair, and after handling waste. The hand-wash sink is for hands only - never for food or equipment.
Safe cooking and reheating temperatures
Getting temperatures right kills harmful bacteria. As a working guide:
- Cook food to a core temperature of 75°C (or an equivalent time/temperature combination).
- Poultry, mince, sausages and rolled joints must be cooked right through.
- Reheat food once only, to 75°C.
- Hot-hold at 63°C or above; cold-hold at 5°C or below.
- Cool cooked food quickly - ideally within 90 minutes - before refrigerating.
Spotting and reporting problems
Good food handlers do not just follow rules, they raise issues. Report a fridge running warm, a pest sighting, a delivery at the wrong temperature, or a colleague working while unwell. A no-blame culture where staff speak up early stops small problems becoming closures. Managers should make reporting quick and welcome it every time.
Why these rules are the law, not just good practice
These habits are not optional. Under EC Regulation 852/2004 and Irish food safety law, food businesses must control hazards and train staff, and the FSAI and local EHOs enforce it. Following the rules protects your customers, your job and your employer's licence to trade. The same rules sit at the heart of every HACCP plan.
Cleaning and the two-stage method
Cleaning is a food hygiene rule that is easy to do badly. Wiping a surface with a cloth spreads dirt around rather than removing bacteria. The correct approach for food-contact surfaces is the two-stage method: first clean to remove visible dirt and grease, then disinfect with a sanitiser left for its full contact time before wiping or drying. Use clean cloths or disposable blue roll, follow the dilution on the sanitiser, and never mix chemicals. A written cleaning schedule that says what, how, when and who keeps it consistent - see our cleaning schedule template.
Why these rules protect you as well as customers
It is easy to see food hygiene rules as box-ticking, but they protect the people following them too. A handler who skips hand-washing or works while unwell can spread illness through a whole kitchen and lose the business its licence to trade. Following the rules keeps your workplace open, your colleagues safe and your own record clean. When everyone treats these habits as non-negotiable, the whole team benefits - which is exactly why training that builds them in is worth the hour it takes.
Key points to remember
- The 4 Cs - Cleaning, Cooking, Chilling and avoiding Cross-contamination - are the core controls.
- Wash hands properly and often; never handle food when unwell with vomiting or diarrhoea.
- Keep food out of the 5°C-63°C danger zone; cook and reheat to 75°C.
- Give accurate allergen information - a legal duty under EU 1169/2011.
- Use FIFO rotation, store raw below ready-to-eat, and clean using the two-stage method.

Frequently asked questions
What are the 4 Cs of food hygiene?
Cleaning, Cooking, Chilling and avoiding Cross-contamination. They are the four core controls every food handler applies to keep food safe.
What temperature is the danger zone?
Between 5°C and 63°C. Bacteria multiply fastest in this range, so keep cold food at or below 5°C and hot food at or above 63°C.
Can I handle food if I am unwell?
Not if you have symptoms such as vomiting or diarrhoea. You must report illness and stay away from food until cleared, as required by food safety rules.
