The Ultimate Guide to Food Safety Fridge Storage: Temperatures, Hygiene & Best Practices
If you are involved in the food industry, proper food storage isn’t optional – it’s essential.
Whether you are a chef, restaurant manager, food manufacturer, or small food business owner, safe food handling is part of your daily responsibility. Storing food properly keeps it fresh and protects both your customers’ health and your business reputation.
While you may use a fridge daily, do you know if you are using it correctly? Are you following the food storage guidelines and maintaining the correct fridge temperature for food safety? Understanding these basics can prevent your food from spoiling and ensure the safety of your customers.
In this article, let’s learn the basics of safe fridge storage, fridge and freezer temperatures, proper food organisation, and hygiene practices.
Why Proper Food Storage Matters
Incorrect fridge storage can cause harmful bacteria to grow rapidly, putting people at risk of serious illness. This isn’t just about rotten food; it’s about unseen microbial threats that can multiply quickly if food is not stored at the right temperature or location.
Storing food at the correct temperature:
- Keeps it safe to eat
- Slows the growth of harmful bacteria
- Helps you meet legal food safety standards
Safe Fridge Temperatures: Legal Limits and Best Practices
Temperature is one of the most crucial factors in maintaining food safety. The legal maximum temperature for storing chilled food is 8°C, but to be on the safe side, it’s strongly recommended to keep your fridge at or below 5°C.
| Type of Storage | Temperature Required | Why It Matters |
| Chilled Food (Legal Limit) | 8 °C or below (legal in England, Wales, NI) | Slows down bacterial growth. Must be followed by law. |
| Best Practice for Fridges | Below 5 °C | Safer than the legal limit. Gives a buffer to keep food cold enough. |
| Danger Zone | 8 °C to 63 °C | Bacteria grow fastest here. Avoid this range when storing or holding food. |
| Freezing | -18 °C or below | Stops bacterial growth completely. |
⚠️ What is the ‘Danger Zone’?
What is it?
The danger zone is the temperature range between 8 °C and 63 °C where bacteria multiply rapidly.
Why avoid it?
Keeping food in this range for too long increases the risk of food becoming unsafe to eat.
Safe practice:
- Keep chilled food below 8 °C
- Keep hot food above 63 °C

Frozen Food Safety: Key Temperature Guidelines
Just like chilled food, frozen food also needs careful temperature control. The ideal freezer temperature is -18°C or lower to keep food safe for longer periods.
Here’s a quick reference chart for frozen storage:
| Aspect | Details |
| Legal Freezer Temperature | -18 °C or lower |
| Best Practice Temperature | -18 °C (consistently maintained) |
| Purpose | Slows down bacterial growth and preserves food for longer |
| Storage Tip | Avoid frequent door openings; ensure air can circulate around food items |
Note: Use a freezer thermometer to ensure the temperature stays consistent at -18°C or lower.
When it comes to food safety, it’s not just about storing food at the right temperature; keeping your fridge clean is just as important.
Safe storage helps stop harmful bacteria from growing, but good fridge hygiene helps prevent dirt, mould, and everyday germs from spreading to your food.
Both food safety and food hygiene play crucial roles in ensuring the quality of food. Food safety focuses on how food is stored (e.g., keeping the fridge at a temperature below 5°C), while food hygiene focuses on where and in what condition it is stored.
For example, meat kept at the right temperature can still become unsafe if stored in a dirty fridge.

How to Store Different Foods in the Fridge: A Simple Guide
Storing different types of food correctly in the fridge is key to keeping them safe, fresh, and hygienic. It helps prevent cross-contamination, improves airflow, and ensures food stays at the right temperature.
Take a quick look at the chart below to learn how to organise the food in your fridge.
Additional Tip: Avoid storing high-risk items like milk or eggs in the fridge door, as it’s the warmest area due to frequent opening.
Fridge Hygiene and Safety Checks Using HACCP
Food businesses across the U.K. use the food safety management system called HACCP (Hazard Analysis and Critical Control Points) to manage both food safety and hygiene.
It is a step-by-step method used to spot potential risks and prevent them before they become a real problem. Whether you run a café, restaurant, or food truck, HACCP helps you keep food safe from start to finish.
Here’s how the 7 Principles of HACCP apply directly to fridge and freezer food safety:
- Conduct a hazard analysis – Identify risks such as temperature fluctuations, improper storage, or poor cleanliness.
- Determine critical control points (CCPs) – Fridge and freezer storage are essential CCPs in any food operation.
- Establish critical limits – Keep chilled food at or below 5°C, and frozen food at -18°C or lower.
- Set up monitoring procedures – Check and record fridge and freezer temperatures at least twice a day, ideally at the start and end of each shift. Use clearly labelled thermometers and ensure staff know what to do if readings are out of range.
Additional Tip: Don’t rely solely on the fridge’s built-in display; place a separate fridge thermometer inside to cross-check accuracy.
- Establish corrective actions – Take clear steps if temperatures exceed safe limits (e.g. move food, call maintenance, record the issue).
Additional Tip: If there’s a power cut, note the time and duration. If the fridge exceeds safe limits for more than 4 hours, the affected food may need to be discarded.
- Verify procedures – Review temperature records and fridge performance regularly to ensure everything’s working as intended.
- Keep documentation – Maintain easy-to-read logs of temperature checks and basic cleaning records to stay compliant during inspections.
In Summary
Fridge food safety is more than setting the right temperature. It’s about following clean practices, storing each item correctly, and applying a system like HACCP to stay in control.

FAQ’s
What is the recommended food safety fridge temperature in the U.K.?
The food safety fridge temperature in the U.K. should be 5°C or lower. Although the legal limit is 8°C, keeping it below 5°C offers better protection.
What is the correct cooling food temperature?
The cooling food temperature should drop from 63°C to 8°C within 90 minutes to meet food safety standards.
What are the food storage guidelines in the U.K.?
According to food storage guidelines in the U.K., chilled foods should be kept below 8°C, and frozen foods at -18°C or lower. Raw and cooked foods must be stored separately to avoid cross-contamination.
What is considered a safe fridge temperature in the U.K.?
A safe fridge temperature in the U.K. is at or below 5°C. This helps slow down the growth of harmful bacteria and keeps food fresh.
What is the ideal food hygiene temperature?
The food hygiene temperature for cold storage is 5°C or below, and for hot holding, it’s above 63°C. These limits help prevent bacterial growth.
