,Chapter 1 — INSPECTION AS THE PRIMARY BASIS FOR FOOD
QUALITY AND SAFETY
Key concept: Pre-loading inspection as a prerequisite program
(PRP) under HACCP/GDP.
Stem: A cold-chain carrier is about to load refrigerated
packaged salads. The QA manager wants the quickest evidence
that the trailer is suitable. Which inspection approach best
protects food safety before loading?
A. A visual check for cleanliness and obvious damage only.
B. A documented inspection including surface cleanliness,
odour check, temperature profile, and recent wash records.
C. Rely on the driver’s verbal confirmation that the trailer is
clean.
D. A check of the delivery schedule and paperwork only.
Correct answer: B
Rationale (correct): A documented, multi-point inspection
(cleanliness, odour, temperature profile and wash records) is
the accepted PRP that feeds HACCP and GDP by verifying the
trailer’s microbiological and temperature readiness before
loading (Chapter 1 — INSPECTION AS THE PRIMARY BASIS…).
This integrates observation with records and measurement,
reducing adulteration risk.
Distractors:
,A. Visual checks alone miss microbiological residues and
temperature performance — insufficient as a sole control.
C. Driver verbal confirmation is unreliable and not an auditable
record.
D. Paperwork without physical inspection cannot confirm actual
container condition or temperature capability.
Teaching point: Combine measurement and records with
inspection to verify loading readiness.

Chapter & Subtopic: Chapter 1 — THE NEED FOR TECHNOLOGY
AND HARD DATA TO ENTER THE CERTIFICATION ARENA
Key concept: Role of objective data (telemetry, dataloggers) in
certification and HACCP verification.
Stem: A shipper wants to demonstrate compliance with ISO
22000 and a customer’s GDP audit for chilled products. Which
data set best supports certification and HACCP verification?
A. The driver’s written note of departure time.
B. Continuous temperature telemetry records for the shipment,
vehicle cleaning certificates, and chain-of-custody logs.
C. A single temperature reading taken on arrival.
D. The invoice and bill of lading only.
Correct answer: B
, Rationale (correct): Continuous telemetry/datalogger records
plus sanitation certificates and chain-of-custody logs provide
objective, auditable evidence required by ISO 22000 and GDP
for HACCP verification — demonstrating control of critical limits
over time (Chapter 1 — THE NEED FOR TECHNOLOGY…). These
data support causal analysis if excursions occur.
Distractors:
A. A driver’s note is subjective and not sufficiently verifiable.
C. A single arrival reading cannot prove control during transit.
D. Commercial paperwork does not show food safety controls
(temperature/sanitation).
Teaching point: Objective continuous data are essential for
verification and certification.

Chapter & Subtopic: Chapter 1 — MOVING TO MEASUREMENT
AND CAUSAL ANALYSIS
Key concept: Using measurement to identify root cause of
temperature excursions.
Stem: During an investigation a shipment shows a 6-hour
temperature excursion mid-route. Which measurement strategy
best supports causal analysis?
A. Interview the driver only.
B. Use segmented temperature logs (cargo sensor, unit ambient
sensor), door-open events and vehicle telemetry for route/time
