The Sanitary Transportation of Human and Animal Food (ST rule) does not require the carrier to carry any specific documentation. Please review the records requirements in the rule. When the carrier and shipper have a written agreement that the carrier is responsible, in whole or in part, for sanitary conditions during the transportation operation, carriers covered by the rule and who are responsible for sanitary conditions during food transportation are required to meet the requirements in section 1.908(e) of the rule. For example, this includes that, if requested by the shipper, a carrier that offers a bulk vehicle for food transportation must provide information to the shipper that identifies the previous cargo transported in the vehicle, or must provide information to the shipper that describes the most recent cleaning of the bulk vehicle.
