Cold and frost storage: temperature-controlled storage and the cold chain
Why the temperature of a cold storage is a safety rule, not a preference
On a regular warehouse, accuracy means getting the right quantity of the right item. On a cold or frozen warehouse, there is an extra dimension: temperature. A food item that has been stored too warm for even a short time can become a health risk without it being visible or smellable. Therefore, temperature control is not a detail — it is a food safety rule that you as a warehouse worker are part of complying with every day.
§What do the rules say about cooling requirements?
After the first part
| Goods type | Maximum temperature |
|---|---|
| Refrigerated food (generally) | 5 °C |
| Fresh fish | 0–2 °C |
| Fresh meat, except poultry | 7 °C |
| Poultry products | 4 °C |
| By-products from slaughter (fresh/chopped) | 3 °C |
| Frozen goods (deep freeze) | -18 °C or colder |
§The cold chain must not be broken
The cold chain is the unbroken series of correct temperature a product must be kept at from producer, through transport and storage, until it reaches the consumer. Break the chain just once — e.g. because a pallet of refrigerated goods stands too long at the loading dock during goods receipt, or because a cold room door is left open — bacterial growth can be set in motion which cannot be reversed by later putting the goods back on cold. For heat-treated food that should be stored or served cold, there is also a requirement for rapid cooling: according to current rules, cooling from 56 °C to 10 °C must occur within 4 hours.
§The warehouse's role in self-control
- 01Check and record temperature on goods receipt before authorizing delivery.
- 02Keep track of the ongoing monitoring of cooling and freezing rooms — many storage facilities have automatic alarms for temperature deviations.
- 03Work quickly at the ramp so refrigerated goods do not stand unnecessarily long at normal room temperature.
- 04Keep raw materials and finished products separate to avoid cross-contamination.
§To work in the cold
Work in a cold storage facility also places demands on you: correct clothing, short, planned stays in the coldest rooms and work planning that minimizes time spent in the cold. Rime and ice on floors and shelves are a real fall risk that must be monitored and reported, as with any other safety deviation in the warehouse.
When temperature is maintained correctly all the way through—from ramp to shelf to shipment—it's not just a system registration. It's the invisible part of warehouse work that ensures the goods are still safe to eat when they land on the customer's table.
