CPFS Purchasing and Inventory 5 — Questions and Answers
Question 1: Which of the following best describes the 'danger zone' as it applies to purchasing and inventory decisions?
- The temperature range between 41°F and 135°F (5°C–57°C) where pathogens grow rapidly (Correct answer)
- The zone on a delivery truck where temperature fluctuates most
- The period after a product's sell-by date
- The range of humidity levels that promote mold growth on dry goods
Correct answer: The temperature range between 41°F and 135°F (5°C–57°C) where pathogens grow rapidly
The temperature danger zone (41°F–135°F) is the range in which most foodborne pathogens multiply rapidly; inventory must be kept outside this range.
Question 2: A restaurant uses a perpetual inventory system. What is the primary advantage of this system over a periodic system?
- It requires less staff time to maintain
- It provides a real-time running count of inventory levels (Correct answer)
- It eliminates the need for physical counts entirely
- It automatically reorders products when stock runs low
Correct answer: It provides a real-time running count of inventory levels
A perpetual inventory system continuously updates stock levels with each transaction, giving managers real-time visibility into current inventory.
Question 3: Which of the following is a key food safety consideration when evaluating a new food supplier?
- Whether the supplier offers volume discounts
- Whether the supplier is inspected and approved by a regulatory authority (Correct answer)
- Whether the supplier delivers on weekends
- Whether the supplier uses branded packaging
Correct answer: Whether the supplier is inspected and approved by a regulatory authority
Supplier approval by a regulatory authority ensures the source meets legal food safety standards required for approved source purchasing.
Question 4: When storing raw meats in a walk-in cooler, which order from top to bottom is correct based on final cooking temperature?
- Poultry, ground beef, whole pork, fish, RTE foods
- RTE foods, fish, whole pork, ground beef, poultry (Correct answer)
- Ground beef, poultry, whole pork, fish, RTE foods
- Fish, RTE foods, poultry, ground beef, whole pork
Correct answer: RTE foods, fish, whole pork, ground beef, poultry
Foods are stored top to bottom from highest to lowest required cooking temperature: RTE on top, then fish, whole pork, ground beef, and poultry at the bottom.
Question 5: Which of the following label elements is most critical when date-marking opened TCS foods for inventory control?
- The brand name and UPC code
- The date the container was opened or prepared (Correct answer)
- The original manufacturer's expiration date
- The employee who opened the container
Correct answer: The date the container was opened or prepared
The FDA Food Code requires TCS foods to be marked with the date they were opened or prepared so that the 7-day maximum hold time can be tracked.
Question 6: A foodservice manager notices that actual food costs consistently exceed theoretical food costs. Which inventory issue most likely explains this discrepancy?
- Overordering leading to excess stock on hand
- Theft, over-portioning, or unrecorded waste (shrinkage) (Correct answer)
- Supplier price increases not yet updated in the system
- Inaccurate menu costing formulas
Correct answer: Theft, over-portioning, or unrecorded waste (shrinkage)
A persistent gap between actual and theoretical food cost typically signals shrinkage — inventory losses from theft, waste, or over-portioning that aren't captured in recipes.
Question 7: Which of the following is the correct procedure when a delivery arrives and the receiving area thermometer reads significantly different from the driver's temperature log?
- Trust the driver's log as it is the official record
- Use the operation's calibrated thermometer to independently verify product temperatures (Correct answer)
- Accept the delivery and recheck temperatures after storage
- Average the two readings to determine acceptability
Correct answer: Use the operation's calibrated thermometer to independently verify product temperatures
The receiving operation should use its own calibrated thermometer to independently verify the internal temperature of delivered products, regardless of what the driver's log states.
