NSF International, working with a retailer, are launching a blockchain traceability service for the beef supply chain. The service will link details of individual cattle on farms all the way through to consumer purchases. Each animal will be given a unique identifier built into a RFID ear tag, along with a sample of DNA and its GPS farm location. As the animal matures, details of its weight and age are entered into the blockchain database, with all the other details as it is processed along the supply chain. This will allow all the supply chain partners to access the blockchain database to improve transparency and traceability. Information about an animal's provenance and quality will even be available to consumers via a mobile phone app and QR code on the pack of beef.
