    4. By touching the food quickly with freshly washed hands
  7. What freezer temperature does the Food Code give to maintain the quality of frozen food?

    1. −18 °C or colder
    2. −8 °C or colder
    3. −2 °C or colder
    4. −40 °C or colder
  8. What temperature range does the Food Code call the "danger zone"?

    1. 10 °C to 40 °C
    2. 60 °C to 74 °C
    3. 0 °C to 4 °C
    4. 4 °C to 60 °C
  9. A salad was prepared and cooled to be served cold later. Where must it be held?

    1. In a hot-holding unit at 60 °C
    2. At room temperature to keep it crisp
    3. At 10 °C, since it is only vegetables
    4. At 4 °C or colder until it is served
  10. Under Alberta's Food Regulation, high-risk food kept cold must be at what temperature?

    1. 0 °C exactly
    2. 10 °C or colder
    3. 4 °C or colder
    4. 7 °C or colder
  11. Food Code temperatures refer to which temperature of the food?

    1. The surface temperature of the container
    2. The internal temperature, unless the food is frozen
    3. The temperature of the air inside the fridge or freezer
    4. The temperature shown on the oven dial
  12. A tray of sandwiches sits at room temperature for immediate service. How long may it stay out?

    1. No more than 2 hours, then it must be thrown out
    2. Up to 4 hours, then it can go back in the fridge
    3. As long as the sandwiches still look and smell fresh
    4. Up to 6 hours if the room is air-conditioned
  13. How accurate must temperature measuring devices be under the Food Code?

    1. Within ±1 °C in the operating range

    4. Within ±5 °C in the operating range
  14. At what temperature must seafood be stored under the Food Code?

    1. 10 °C
    2. 3.3 °C
    3. 7 °C
    4. 5 °C
  15. What must every refrigerator and hot-holding unit in a commercial kitchen have?

    1. A glass door
    2. A digital clock

Temperature control: 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. 25 Storage, display and transportation

  • High-risk food must be stored, displayed and transported at 4 °C or colder, or at 60 °C or hotter, unless a health inspector (executive officer) approves other temperatures.
  • Food that must be frozen to stay fit to eat must stay frozen while stored, displayed, packaged or transported.
  • Whole raw shell eggs must be kept at 7 °C or colder.

s. 18 Equipment

  • Refrigeration and hot-holding equipment must be big enough for the establishment, able to keep the required temperatures and fitted with an accurate thermometer.

s. 3.3 Temperature control

  • All temperatures are internal product temperatures unless the product is frozen.
  • Frozen foods must be kept at 0 °C or colder; −18 °C or colder keeps their quality.
  • All potentially hazardous food, including food prepared and cooled to be served cold, is stored at 4 °C or colder; seafood at 3.3 °C.
  • Hot food is held at 60 °C or hotter.
  • The temperature "danger zone" is between 4 °C and 60 °C; the time food spends in it affects safety and shelf life.
  • Potentially hazardous food meant for immediate consumption may be held at room temperature (not on ice) for no more than 2 hours, then must be thrown out; it must be marked with the time it was taken out of temperature control.

s. 4.1.11 and 4.1.12 Thermometers

  • Equipment that cooks, cools, stores or freezes potentially hazardous food needs devices to monitor and control temperature.
  • Thermometers must be easy to read, accurate to ±1 °C and calibrated regularly, with calibration records kept.
  • Food thermometers should not have glass sensors or stems unless in a shatterproof sleeve.

s. 42 (temporary food establishments)

  • Probe thermometers and cold-storage thermometers must be used to check storage and preparation temperatures.
