In Wake of Romaine E. coli Scare, Walmart Deploys Blockchain to Track Leafy Greens
How do you know your food is safe to eat?
This isn’t a question many of us often ask ourselves. But lately, food safety has been in the public eye: 2018 has already seen a large outbreak of E. coli in romaine lettuce and Salmonella in a number of products from eggs to breakfast cereal.
Walmart Asks Suppliers of Leafy Greens to Use Blockchain
Walmart and Sam’s Club recently sent a letter to suppliers of fresh, leafy greens asking them to trace their products all the way back to the farm using blockchain technology. Suppliers are expected to have all these systems in place by this time next year.
This change means that the information gathered by these suppliers will be open and accessible through technology that offers real-time, end-to-end traceability from farm to table. Blockchain allows for digitized sharing of data in a secure and trusted way.
