Thawing, cooking, cooling and reheating: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

s. 3.3.2 Thawing

  • Thaw potentially hazardous food quickly or in a way that prevents rapid bacterial growth: in the refrigerator at 4 °C or less, completely under cold running water, as part of cooking (if the cooking time allows for it) or in a microwave.
  • If thawed portions are above 4 °C, the total time above 4 °C, including preparation and cooling back below 4 °C, must not exceed 4 hours.
  • Frozen ready-to-eat seafood is thawed at 3.3 °C or less.

s. 3.3.4 and Appendix B Cooking

  • Raw foods of animal origin must reach the minimum internal temperatures and times in Appendix B in all parts, stirring mixtures so every part heats.
  • Food mixtures containing poultry, eggs, meat, fish or other potentially hazardous foods: 74 °C for at least 15 seconds.
  • Poultry: 74 °C for 15 seconds. Stuffing in or containing poultry, fish or meat: 74 °C for 15 seconds.
  • Ground meat (chopped, ground, flaked or minced beef, pork or fish): 71 °C for 15 seconds.
  • Eggs: 63 °C for 15 seconds. Fish: 68 °C for 15 seconds. Rare roast beef: 63 °C for 4 minutes.
  • The same lethality can be reached at lower temperatures held longer: a beef roast at 54 °C for 121 minutes equals 63 °C for 3 minutes.
  • Where raw or lightly cooked foods are served (raw oysters, steak tartare, raw-egg shakes), customers should be told about the increased risk.

s. 3.3.6 and 3.3.7 Cooling

  • Cooked potentially hazardous food is cooled from 60 °C to 20 °C within 2 hours, then from 20 °C to 4 °C within the next 4 hours.
  • Food prepared at room temperature (including from canned or reconstituted ingredients) must be cooled to 4 °C within 4 hours.
  • Large items such as roasts, turkeys and big pots of rice cool slowly; dividing food into smaller containers speeds cooling. Refrigerators are designed to hold cold food, not to cool large masses.

s. 3.3.9 to 3.3.11 Reheating and microwaves

  • Cooked and cooled food reheated for hot holding must reach 74 °C or higher, passing through the danger zone as quickly as possible.
  • Food that has been cooled, reheated and cooled again must be reheated to 74 °C with no more than 2 hours in total between 4 °C and 74 °C.
  • Food cooled once may be served immediately at any temperature if it spends no more than 2 hours between 4 °C and 60 °C.
  • In a microwave, rotate or stir the food during cooking, heat all parts to at least 74 °C, and let it stand covered for at least 2 minutes; check the temperature in several places.

s. 3.3.12 Freezing for parasites

  • Fish to be eaten raw or partly cooked must be frozen to −20 °C or below for 7 days, or to −35 °C until solid and stored at −35 °C for 15 hours.
