Registering core temperatures is mandatory for high-risk dishes like meat, fish and poultry. Without proper registration you risk NVWA inspections and can't prove you worked correctly in case of food poisoning. Here's how to register and maintain core temperatures step by step.
Why register core temperature?
Preparing meat, fish and poultry requires killing bacteria through sustained high temperatures. The core temperature measures heat in the product's thickest section - a pattern we see repeatedly in restaurant financials shows inadequate temperature monitoring leads to costly food safety violations.
⚠️ Note:
Meat's exterior might reach 75°C while the interior stays at 45°C. Only core temperature matters for food safety.
What temperatures are required?
Minimum core temperatures vary by product type:
- Poultry (chicken, turkey): 75°C
- Ground meat (beef, pork): 75°C
- Whole cuts of meat: 65°C (held for 2 minutes)
- Fish: 65°C
- Eggs (bound sauces): 75°C
💡 Example:
You're preparing chicken satay for 40 people:
- Core temperature measured: 76°C
- Time: 19:45
- Staff member: Sarah
- Dish: Chicken satay
Registration: ✓ Meets 75°C requirement
What do you need to register?
Record these details for each measurement:
- Date and time: Measurement moment
- Dish/product: What you prepared
- Measured temperature: In degrees Celsius
- Meets requirement yes/no: Above minimum temperature
- Staff member: Who took the measurement
- Action if deviation: Steps taken if temperature's too low
How often to measure?
Measurement frequency depends on your preparation method:
- Per batch: Large quantities (20+ portions)
- Per service: Standard preparation
- Spot checks: Routine dishes (minimum once daily)
- Always: New dishes or new staff members
💡 Example registration:
Tuesday February 19, 2025, 18:30
- Product: Beef steak medium
- Core temperature: 68°C
- Required: 65°C
- Meets requirement: Yes
- Measured by: Tom
Digital vs paper registration
You can track core temperatures on paper or digitally. Both methods are acceptable, but digital offers advantages:
- Paper: Inexpensive, always accessible, but risk of loss
- Digital: Searchable, automatic timestamps, cloud backup
Digital platforms often include HACCP modules where you can log core temperatures via smartphone. Convenient during cooking.
⚠️ Note:
Apps don't register automatically. You must measure temperature and input data manually. The app only assists with recording and storage.
What if temperature is too low?
If core temperature falls short:
- Continue heating: Until proper temperature's achieved
- Re-measure: Verify correction
- Document: Initial measurement plus corrective action
- Don't serve: Until temperature's adequate
Keeping registrations
Maintain all core temperature records for at least 2 years. Digital systems handle this automatically. With paper records: establish a reliable filing system.
💡 Practical tip:
Photograph paper registrations with your phone. This creates backup copies if originals get lost.
Register core temperature (step by step)
Measure the core temperature
Insert the thermometer in the thickest part of the meat, fish or poultry. Wait until the temperature is stable. Don't measure against bone or fat.
Check if temperature meets requirement
Compare with the minimum requirement for that product. Poultry and ground meat: 75°C. Whole cuts of meat and fish: 65°C. Too low? Heat further.
Register immediately
Note date, time, product, measured temperature, whether it meets requirement and your name. Do this right away, not later. With digital registration: fill in on your phone or tablet.
Keep the registration
Make sure the registration is kept for at least 2 years. With paper: in a folder. With digital: automatically saved in the cloud.
✨ Pro tip
Set your digital thermometer alarm to the minimum required temperature - it'll beep at exactly 75°C for poultry or 65°C for fish. This prevents overcooking while ensuring food safety compliance.

Frequently asked questions
What if my thermometer is broken?
You can't continue preparing high-risk dishes without a working thermometer. Temperature measurement is mandatory for these products. Always keep a spare thermometer on hand.
How often do I need to calibrate my thermometer?
Calibrate at least monthly by testing in ice water (should read 0°C) and boiling water (100°C). If readings deviate, replace the thermometer or have it professionally repaired.
Do I need to measure core temperature with sous-vide cooking?
Yes, sous-vide requires temperature monitoring too. While water temperature might be correct, the product must maintain proper temperature long enough to eliminate bacteria. Document these measurements like any other cooking method.
