How the FSANZ 2-hour/4-hour rule works for ready-to-eat potentially hazardous food, with the time table, how to track it, and the cooling limits.

Potentially hazardous food should be kept at 5°C or colder or 60°C or hotter. That isn't always practical, for example while you're making sandwiches or have food on display. FSANZ's 2-hour / 4-hour rule tells you what you can do with ready-to-eat potentially hazardous food that has been out of the fridge.

The rule

Total time between 5°C and 60°CWhat you can do
Less than 2 hoursUse it, sell it, or put it back in the fridge to use later
2 to 4 hoursUse it or sell it, but don't put it back in the fridge
4 hours or moreThrow it out

The time adds up

The time is cumulative. Add up every period the food spent between 5°C and 60°C, including preparation, storage, transport and display. Start timing as soon as the food comes out of refrigeration.

How to keep track

What counts as potentially hazardous food?

FSANZ's examples: raw and cooked meat and dishes containing meat; dairy and dairy-based desserts; seafood (other than live seafood); processed fruit and vegetables such as salads; cooked rice and pasta; foods containing eggs, beans, nuts or other protein-rich ingredients, such as quiche and soy products; and foods that contain any of these, such as sandwiches and rolls.

Related limit: cooling cooked food

Cooked potentially hazardous food that you're cooling for later must go from 60°C to 21°C within 2 hours, then from 21°C to 5°C within a further 4 hours. If you use a different method, you must be able to show it's a safe alternative.
