Worked explanations
The paper carries one for every question, at the back. These are the three above.
Q1
B
Ch. 4: Ensuring Product Time and Temperature
Answer: B - A device with a glass sensor or stem that is not enclosed in a shatterproof coating
Because Food temperature measuring devices may not have sensors or stems constructed of glass, except that thermometers with glass sensors or stems encased in a shatterproof coating, such as candy thermometers, may be used. Food Code 4-201.12
The hazard is physical rather than microbiological. A glass thermometer breaking in a stockpot contaminates the whole batch with fragments nobody can remove. Food Code 3-307.11
Where the other options lead
- A.Banned infrared. Infrared has legitimate uses for surface screening. It is not prohibited, it is simply not an internal temperature device.
- C.Rejected the thermocouple. A small-diameter probe designed for thin masses is expressly required to be available for foods such as patties and fillets.
- D.Rejected dual scaling. The Code writes accuracy tolerances for dually scaled devices, so it plainly contemplates them.
Q2
D
Ch. 5: Monitoring the Flow of Foods
Answer: D - That the two-stage cooling schedule is met, and that ready-to-eat cooked chicken is not contacted with bare hands during portioning
Because Cooked TCS food must be cooled within 2 hours from 57°C (135°F) to 21°C (70°F) and within a total of 6 hours to 5°C (41°F) or less, and separating food into smaller portions is one of the named cooling methods. Food Code 3-501.14
Cooked chicken is ready-to-eat, so portioning it requires a suitable utensil rather than bare hands. Two provisions apply to the same act, which is what makes this a monitoring point rather than a single check. Food Code 3-301.11
Where the other options lead
- A.Read the first stage as guidance. Both limbs are requirements, and the first is where most of the growth risk sits.
- B.Compressed the schedule. Two hours is the first stage to 70°F. The total to 41°F is six hours.
- C.Reheated before cooling. The chicken is already hot from cooking. Reheating it adds a cycle and achieves nothing.
Q3
A
Ch. 4: Ensuring Product Time and Temperature
Answer: A - Food temperature measuring devices must be provided and READILY ACCESSIBLE for ensuring the attainment and maintenance of the required food temperatures
Because Food temperature measuring devices must be PROVIDED AND READILY ACCESSIBLE for use in ensuring attainment and maintenance of food temperatures as specified under Chapter 3. Food Code 4-302.12
Readily accessible is what makes monitoring happen. A single probe locked in an office is a device the line cook does not use, and a probe that has been in a cooler all night reads slowly when it is needed. Food Code 4-502.11
Where the other options lead
- B.Centralised the device. One device held by one person is not readily accessible to the employees who must check temperatures.
- C.Required personal issue. Sensible in some operations and not a Code requirement.
- D.Required cold storage. Nothing requires it, and a probe must be cleaned and sanitised between uses rather than stored among food.
