3.6 Transportation & Receiving Procedures
Key Takeaways
- The FSMA Sanitary Transportation rule (21 CFR Part 1 Subpart O) assigns written responsibilities to shippers, loaders, carriers, and receivers for temperature control, vehicle sanitation, and training.
- Receiving criteria are absolute: cold TCS at 41°F or below, hot TCS at 135°F or above, frozen food solid with no evidence of thawing and refreezing, and shellstock with an intact tag.
- Shellstock tags must be retained for 90 days from the date the last shellfish was used, and shucked shellfish container labels for 90 days as well.
- Food Code 3-202.11(B) lets molluscan shellfish and milk be received above 41°F at the temperature their governing law specifies, and 3-501.14(C) then requires cooling to 41°F within 4 hours of receipt.
- Rejection is a receiving decision, not a storage decision — once a deficient load is accepted and put away, the establishment owns the hazard.
3.6 Transportation & Receiving Procedures
Exam Tip: Blueprint task A.19 explicitly includes "identifying hazards to specific modes of transportation." Do not study receiving as a single generic dock activity — refrigerated truck, ocean container, air freight, and rail each fail differently.
The Sanitary Transportation of Human Food Rule
FSMA's Sanitary Transportation rule (21 CFR Part 1, Subpart O) governs food shipped by motor vehicle and rail within the United States. It assigns duties to four roles, and exam items typically test who owns what.
| Role | Core responsibility |
|---|---|
| Shipper | Specifies in writing the sanitary requirements for the vehicle and the operating temperature, including pre-cooling |
| Loader | Verifies before loading that the vehicle is in appropriate sanitary condition and pre-cooled if required |
| Carrier | Meets the shipper's written specifications, and on request demonstrates that temperature was maintained |
| Receiver | Assesses on arrival whether the food was subjected to significant temperature abuse |
Additional requirements: records of written agreements, procedures, and training must be retained (generally 12 months), carrier personnel must be trained in sanitary transportation practices when the carrier is assigned responsibility for temperature control, and bulk vehicles' previous cargo must be considered so that a tanker that hauled a non-food chemical is not used for food.
The rule's small-business exemptions and its exclusion of fully enclosed shelf-stable food, live animals, and food transshipped through the U.S. are the usual scope questions.
Hazards by Mode of Transportation
| Mode | Characteristic hazards |
|---|---|
| Refrigerated truck (reefer) | Unit cycling off during stops; air delivery blocked by overloading above the load line; door-open dwell at multi-stop routes; no continuous temperature record |
| Ocean container | 3–6 week transit with no intervention possible; condensation "container rain" wetting cases; loss of reefer power at transshipment; pest and rodent ingress at port |
| Air freight | Rapid pressure and temperature swings; long tarmac dwell outside refrigeration; heavy reliance on gel packs and phase-change materials rather than active cooling |
| Rail | Very long dwell in yards; limited monitoring; extreme ambient exposure |
| Bulk tanker | Previous-cargo contamination; inadequate wash between loads; missing wash tickets |
| Last-mile / own vehicle | Employee personal cars, unrefrigerated hot boxes, no thermometer, food carried with cleaning chemicals |
The general rule to carry into an assessment: the longer the transit and the fewer the intervention points, the more the control depends on the loading condition and on a continuous temperature record.
Receiving Criteria
The receiving dock is a control point, and in many HACCP plans it is a critical control point. Written procedures must specify who inspects, what is checked, what the criteria are, and what happens on failure.
| Item | Acceptance criterion |
|---|---|
| Cold TCS food | 41°F (5°C) or below |
| Hot TCS food | 135°F (57°C) or above |
| Frozen food | Solid, with no large ice crystals, no fluid stains on packaging, and no evidence of thaw-refreeze |
| Live molluscan shellfish | Received with the harvester or dealer tag intact and attached; the tag identifies harvest waters and date. Food Code 3-202.11(B) lets shellstock be received at the temperature specified by the law governing its distribution (the NSSP, commonly 45°F) rather than 41°F |
| Shell eggs | Received at an ambient air temperature of 45°F (7°C) or below |
| Milk and dairy | Pasteurized, Grade A, at 41°F or below |
| Reduced oxygen packaged food | Intact seal, no swollen or leaking packages, within date |
| Canned goods | No severe dents on seams or rims, no swelling, no rust through, no leaks, label intact |
| Packaging | Dry, intact, no punctures, no pest evidence, no water stains |
Shellfish tags
The tag rule is a favorite exam target. Retain shellstock tags for 90 days from the date the last shellfish from that container was sold or served, marking the tag with that date. Shucked shellfish container labels are retained on the same 90-day basis. The purpose is traceback: when a Vibrio or norovirus cluster is linked to oysters, the tag is what identifies the harvest area and date.
Molluscan shellfish and milk are the two foods the Food Code singles out in 3-202.11(B): because other law governs their distribution temperature, they may be received above 41°F at the temperature that law specifies. 3-501.14(C) then requires any such food to be cooled to 41°F or less within 4 hours of receipt.
Temperature measurement technique
- Packaged food: place the thermometer probe between two packages without puncturing, or use an infrared thermometer on the surface. Never puncture a sealed package to check temperature.
- Bulk or unpackaged food: insert a calibrated thin-probe thermometer into the thickest part, avoiding contact with the container.
- Sample size: check multiple pallets and multiple positions in the load, not just the one carton nearest the door.
- Sanitize the probe between products.
Rejection
Reject at the dock. Once a deficient load is signed for and put into storage, the establishment owns the hazard and the loss.
The written procedure should state:
- Set the load aside and do not commingle it with accepted stock.
- Record the deficiency: item, quantity, lot or invoice number, measured temperature or observed condition, date, time, and receiver name.
- Note the rejection on the delivery invoice and have the driver initial it.
- Return the product on the delivery vehicle where possible; if it must be held pending pickup, mark it "REJECTED — DO NOT USE" and segregate it physically.
- Notify purchasing and the supplier, and track repeat deficiencies for supplier performance review.
A credit memo is not a food safety record. The temperature log and the annotated invoice are.
Under the FSMA Sanitary Transportation of Human Food rule, whose responsibility is it to specify in writing the operating temperature and sanitary condition required of the vehicle?
A restaurant receives a case of live oysters at 45°F with an intact harvester tag, the temperature permitted by the shellfish law governing their distribution. What is the correct handling?
Which transportation mode presents the specific hazard of condensation wetting product cases over a multi-week transit with no opportunity for intervention?
A receiver measures a case of packaged deli meat at 47°F, signs for the delivery, and places it in the walk-in intending to sort it out later. What is the primary problem with this sequence?
