Sanitary Transportation of Human Food: What the FSMA Rule Means for Foreign Exporters

The FSMA Final Rule on Sanitary Transportation of Human and Animal Food (21 CFR Part 1, Subpart O) addresses the conditions under which food is transported within the United States and — indirectly — the conditions under which food is transported from foreign origins to US ports. While the rule primarily applies to shippers, carriers, loaders, and receivers operating within the US, foreign exporters are affected because the condition of their food upon arrival at the US port reflects the transportation conditions from the point of origin. Food that arrives at a US port showing signs of temperature abuse, contamination, or insanitary transport conditions may be refused entry, and the FSMA framework provides FDA with the tools to hold shippers and receivers accountable for transportation-related food safety failures.

Who the Sanitary Transportation Rule covers

The rule applies to shippers, loaders, carriers by motor vehicle or rail vehicle, and receivers engaged in the transportation of food within the United States. A shipper is the person who arranges for the transportation of food by a carrier or who first tenders food for transportation. A carrier is the person who physically transports food. A loader is the person who loads food onto a motor vehicle or rail vehicle during transportation. A receiver is the person who receives food at the end of transportation. The rule does not directly cover ocean vessels or international air carriers, but the food that arrives via those modes is received by a US-based receiver who is covered by the rule — and that receiver is responsible for verifying that the food was not rendered unsafe during transportation.

Vehicle and equipment requirements

The rule requires that vehicles and transportation equipment be designed and maintained to prevent food from becoming unsafe during transportation. This includes ensuring that vehicles are clean and free from contamination before food is loaded, that refrigeration units are functioning properly and maintaining the required temperature, that the vehicle's prior cargo did not leave residues that could contaminate food, and that the vehicle provides adequate protection from environmental contamination. For bulk and non-packaged food, these requirements are especially critical — a tanker truck that previously carried chemicals, for example, must be thoroughly cleaned and inspected before being used to transport liquid food ingredients.

Temperature control requirements

For food that requires temperature control for safety — including fresh produce, dairy, meat, seafood, frozen foods, and ready-to-eat foods — the rule requires that the shipper specify temperature requirements in writing (or by equivalent electronic means) to the carrier. The carrier must maintain the specified temperature during transportation and must have the equipment and procedures to do so. Pre-cooling of the vehicle to the specified temperature before loading is required when necessary to maintain product safety. Temperature monitoring during transportation — either through continuous recording devices, spot checks at loading and unloading, or other validated methods — is expected as part of the carrier's compliance program.

Prior load requirements and cross-contamination prevention

One of the most important provisions of the Sanitary Transportation Rule addresses prior loads — what was in the vehicle before the current food shipment. The shipper must take reasonable measures to ensure that the vehicle has not been used to transport materials that could contaminate the food. This includes requiring the carrier to disclose prior loads and, for certain food types, requiring cleaning or sanitization of the vehicle between loads. For food shipped in bulk — such as grain, flour, oil, or juice — the prior load history of the tanker, hopper car, or container is particularly important because residues from previous loads can adulterate the food. Foreign exporters who ship bulk food ingredients in containers or tankers should establish agreements with their logistics providers that specify prior load restrictions and cleaning requirements.

Written procedures and agreements

The rule requires shippers, carriers, and receivers to establish and maintain written procedures, agreements, or other documentation specifying the sanitary transportation requirements applicable to their operations. These documents should cover temperature specifications, prior load restrictions, vehicle cleaning requirements, and responsibilities for monitoring and record-keeping. While the rule does not prescribe a specific format for these documents, the FDA expects that they be sufficiently detailed to ensure that each party understands its responsibilities and that compliance can be verified. Records must be maintained for 12 months.

Exemptions from the Sanitary Transportation Rule

The rule includes several exemptions. Shippers, carriers, or receivers with total annual food sales below $500,000 are exempt. Food that is completely enclosed by a container that prevents contamination and that does not require temperature control for safety (such as canned goods, bottled beverages, or sealed snack packages) is exempt from the vehicle sanitation and prior load requirements, although temperature-controlled enclosed products remain covered. Transportation by farm operations of raw agricultural commodities from the farm is exempt. Transportation of food by the manufacturer or shipper using their own vehicles, when the food will be held by the shipper and not transferred to another party, is exempt.
