How IoT temperature sensor data is hashed and embedded in the agricultural DPP to create a continuous cold-chain integrity record from South African packhouse to EU port of entry.
EU Food Safety Regulation 178/2002 establishes the general principles and requirements of EU food law, including the requirement that food business operators maintain traceability throughout the food chain. For perishable products like citrus, this means maintaining a continuous cold-chain record from the packhouse to the EU port of entry. Temperature excursions — periods where the product's temperature exceeds the specified range — can compromise food safety and quality, and EU importers are required to demonstrate that their supply chain has maintained the cold chain integrity. The National DPP Registry's cold-chain logging module creates a forensically verifiable temperature record for each consignment.
Modern reefer containers are equipped with IoT temperature sensors that log temperature data at regular intervals (typically every 15 minutes) throughout the voyage. The National DPP Registry integrates with the major reefer container tracking platforms (Maersk Remote Container Management, CMA CGM Track & Trace) to pull temperature log data for South African agricultural consignments. The temperature log is SHA-256 hashed at the point of data retrieval, creating a tamper-evident record of the cold-chain performance. Any retrospective alteration to the temperature log — to conceal a temperature excursion — would invalidate the hash and immediately reveal the tampering.
The National DPP Registry's AI monitoring system continuously analyses temperature log data for excursions. When a temperature excursion is detected — for example, if the reefer container temperature rises above 8°C for more than 2 hours — the system generates a Human-in-the-Loop alert to the exporter and the EU importer. The alert includes the GPS coordinates of the vessel at the time of the excursion, the duration and magnitude of the temperature deviation, and a recommendation for whether the consignment should be accepted, rejected, or subjected to additional inspection at the EU border inspection post.
Upload your temperature proof document to the Minting Station. The SHA-256 hash is computed client-side in your browser — the raw file never leaves your device unprotected. The hash is your forensic fingerprint: tamper-evident and legally non-repudiable under ECTA 2002.
