,Chapter 1 — Inspection as the Primary Basis for Food Quality
and Safety
Key concept: Role and limits of visual inspection in transport
hygiene.
Stem: A regional transporter inspects an incoming refrigerated
trailer visually and finds it “appears clean.” Which action best
aligns with a risk-based approach to ensure food safety before
loading high-risk perishable goods?
Options:
A. Accept the trailer because visual inspection showed no
visible residues.
B. Accept the trailer but require documentation of prior load
type only.
C. Reject the trailer unless a written sanitation certificate and
temperature log are provided.
D. Accept the trailer if the driver signs they performed cleaning.
Correct Answer: C
Rationale (correct): Visual inspection alone cannot reliably
demonstrate microbiological safety or proper prior cleaning;
combining visual check with sanitation certificate and historical
temperature records is risk-based and consistent with transport
hygiene guidance. Chapter 1, Inspection as the primary basis
(2–3 sentences). (FAOHome, U.S. Food and Drug
Administration)
,Why A is wrong: Visual appearance can miss residues,
allergens, or temperature breaches; it’s not sufficient evidence
of sanitation.
Why B is wrong: Prior load documentation without sanitation
verification or temperature history leaves microbial and cross-
contact risks unaddressed.
Why D is wrong: A driver’s unverified statement is not an
objective control and lacks documentary evidence for
auditability.
Teaching point: Combine inspection with paperwork and
temperature history for verified transport readiness.

Chapter & Subtopic: Chapter 1 — The Need for Technology and
Hard Data to Enter the Certification Arena
Key concept: Role of continuous data logging for certification
and traceability.
Stem: A cold-chain operator seeks certification and must
demonstrate control of product temperature during transit.
Which measurement approach best supports certification?
Options:
A. Occasional spot checks at origin and destination.
B. Manual temperature checks once per day by drivers.
C. Continuous electronic temperature logging with tamper-
, evident records.
D. Relying on driver notes in paper manifests.
Correct Answer: C
Rationale (correct): Continuous electronic logging provides
time-stamped, tamper-evident evidence of temperature control
— required for robust traceability and accepted by modern
food safety schemes and regulatory guidance. Chapter 1, Need
for technology and hard data. (ISO, U.S. Food and Drug
Administration)
Why A is wrong: Occasional checks miss excursions between
checks and provide poor evidence for certification.
Why B is wrong: Manual once-daily checks lack granularity and
are prone to transcription error.
Why D is wrong: Paper driver notes are easily altered and
insufficient for audit trails.
Teaching point: Use continuous, tamper-evident data logging
for reliable certification evidence.
