Walmart Tests Blockchain For Use In Food Recalls

An anonymous reader quotes a Bloomberg article about Walmart:Like most merchants, the world's largest retailer struggles to identify and remove food that's been recalled. When a customer becomes ill, it can take days to identify the product, shipment and vendor. With the blockchain, Wal-Mart will be able to obtain crucial data from a single receipt, including suppliers, details on how and where food was grown and who inspected it... "If there's an issue with an outbreak of E. coli, this gives them an ability to immediately find where it came from. That's the difference between days and minutes," says Marshal Cohen, an analyst at researcher NPD Group Inc...." In October, Wal-Mart started tracking two products using blockchain: a packaged produce item in the U.S., and pork in China. While only two items were included, the test involved thousands of packages shipped to multiple stores... If Wal-Mart adopts the blockchain to track food worldwide, it could become of the largest deployments of the technology to date. America's Centers for Disease Control and Prevention estimates roughly their recalls affect roughly 48 million people annually, according to the article, "with 128,000 hospitalized and 3,000 dying."
