A trailer arrives with a washout receipt, and the dock asks whether loading can start. The receipt answers part of the question: a cleaning service was recorded. Your team still needs to connect that service to this trailer, its present condition, and the food about to be loaded.
Use these six checks to organize a sanitation review with the shipper's responsible food-safety contact. FDA identifies inadequate cleaning between loads and contamination from previous cargo as transportation concerns; its rule has a defined scope and exemptions. The worksheet below is an operational aid, not an official FDA checklist. FDA sanitary transportation overview.
1. Identify the next load's actual acceptance requirements
Record the product, packaging, and written sanitation requirements supplied for the shipment. Specify who can interpret those requirements. An instruction for sealed cartons may leave different questions open than an instruction for exposed food. Do not let dispatch invent a cleaning standard when the shipper's requirement is missing.
2. Connect the cleaning record to the equipment and sequence
Match the trailer identifier, service location, date, and available service description. Ask what happened after the service: another load, temporary storage, or a trailer substitution changes the sequence you are reviewing. A receipt for yesterday's trailer does not document the replacement unit standing at the dock.
3. Record observations without turning them into a safety verdict
Have the designated person document accessible surfaces, visible residue, standing liquid, unusual odors, and damage that needs review. Note the location of each finding and retain photographs where permitted. A visual check records what was observed; it does not establish that allergens or microorganisms are absent.
4. Route prior-cargo questions through the agreed process
Ask for the history needed by the shipper's sanitation program and flag missing information. Avoid claiming every reefer must provide a universal number of previous loads. FDA's specific previous-cargo and most-recent-cleaning information provisions discussed in its FAQ concern bulk vehicles and the applicable carrier responsibilities. Broader customer requirements need their own basis. FDA sanitary transportation FAQ.
5. Make corrective work and reinspection explicit
If a concern remains, record who specifies the correction, who performs it, and who checks the result. “Sent for another wash” describes an action in progress. It does not document a completed review. Keep sanitation acceptance separate from precooling and product-temperature checks; completion of one does not answer the others.
6. Name the person who closes the open item
Preserve the decision, its basis, any conditions, and the time. A dispatch note should distinguish “records received,” “review pending,” and “accepted by the designated reviewer.” Carry unresolved items into the next handoff rather than allowing a completed paperwork field to hide them.

Worked example — hypothetical
Trailer T-14 has a matching receipt, but the loader observes an unexplained odor. Record the receipt match and odor as separate facts. The sanitation review remains open while the shipper's designated contact assesses the observation and specifies any correction. If the trailer changes to T-22, start the equipment-specific review again; T-14's paperwork cannot close T-22's open items.
