Storage Hierarchy

Storage hierarchy is the organised placement of foods in refrigerators and walk-in coolers to reduce cross-contamination. Raw foods are stored below ready-to-eat foods, with placement of raw animal products based on the risk of leakage and the required cooking process. The exact order should follow local food-safety requirements and the operation’s food-safety plan.

Typical refrigerator order

A common risk-based arrangement from top to bottom is:

1. Ready-to-eat foods and cooked foods.
2. Washed produce and foods requiring minimal preparation, stored separately as appropriate.
3. Raw seafood and whole cuts of beef or pork.
4. Ground or comminuted meats.
5. Raw poultry at the lowest level.

The arrangement may vary with the cooking temperatures and hazards of the products stored. All foods must be covered, labelled and protected from drips. Raw and ready-to-eat products should be separated physically wherever possible.

Why hierarchy matters

Raw meat, poultry and seafood can release juices containing pathogens. Storing them below ready-to-eat foods reduces the risk that drips will contaminate food that will not receive further cooking. Shelving, containers and dedicated zones should support this separation.

Example: raw poultry is stored in a covered, leak-proof container on the lowest shelf, while ready-to-eat desserts and cooked foods are stored above in protected containers.

Storage hierarchy versus FIFO

Storage hierarchy determines where foods are placed to reduce contamination risk. FIFO and FEFO determine how stock is rotated by receipt date or expiry date. Both systems are needed.

Chef’s safety note: follow the local health authority’s storage-order requirements, keep products covered and labelled, and clean spills immediately.
