Cold storage — Food Safety Glossary

Storing potentially hazardous food at 5 degrees Celsius or below to slow bacterial growth and keep it safe.

Frequently asked questions

What is cold storage?

Storing food at low temperatures, generally at 5 degrees Celsius or below, to slow the growth of bacteria that cause food poisoning and spoilage.

What temperature should cold storage be?

Potentially hazardous food should generally be kept at 5 degrees Celsius or colder, unless a time-based control such as the two-hour four-hour guidance applies or the food is frozen.

Does cold storage kill bacteria?

No. Chilling slows bacterial growth rather than killing most bacteria, which is why cold storage keeps food safe for a limited time rather than indefinitely.

How should food be arranged in cold storage?

Ready-to-eat food should be stored above raw food to prevent drips, and stock should be rotated using First In, First Out so older items are used first.

Why record cold storage temperatures?

Recording temperatures shows the food was kept out of the temperature danger zone, supports monitoring under a food safety program, and helps spot equipment problems early.
