Wal-Mart Using Blockchain To Make Your Salads Safe


We’ve written about many things over our 2+ years in publication at FintekNews, but one thing we have NOT written about is salads.  That is, until today.  Because the big news on the “fintech salad front” (yes, we have designated that to be a “thing”) is that Wal-Mart is growing ever closer to having its entire leafy green produce on the blockchain.  And that’s good news because it means there will be a tracking mechanism in place in the future to determine sources of contamination quickly and easily  And of course greens are just a start, but they’re an important start because they are a frequent source of food contamination.  Wal-Mart has been working with IBM on this system for over a year and it will be fully in place by September 2019.  In the meantime, next time you eat a salad, remember those lovely greens are not only good for you, but a good use case for the future of technology, too.

“Earlier this year 210 people from 36 states were sickened after eating Romaine lettuce they purchased from Wal-Mart. Somewhere in the food chain, the lettuce had become tainted with E. coli. Obviously this is not a new story or a unique concern, but what is unique is Wal-Mart’s approach to solving the problem.

Over the last 18 months, Wal-Mart has tested IBM’s Hyperledger blockchain solution called Food Trust. Tracking everything from berries to chicken has produced a complete view of the chain of custody from the farmer to the store. If successful, Wal-Mart will be one of the first Fortune 500 companies to deploy a blockchain solution into production.

Wal-Mart has mandated that all suppliers of leafy greens adopt the Food Trust system by September 30, 2019. The adoption of this system will allow end-to-end tracking from the approximately 100 farms that supply greens to Wal-Mart stores. When contamination does occur, the source can be narrowed down in a few seconds versus a week of manual research…”
