Walmart is serious about blockchain. It has applied for a number of patents to use blockchain for such things as storing payment data and creating a secondary marketplace for its customers reselling products purchased at its stores.
But in the aftermath of the recent E. coli bacteria contamination of romaine lettuce that officials say killed five and sickened at least 197 people in 35 states, Walmart and nine other major food companies have turned to blockchain to change the way the industry tracks food worldwide to prevent another crisis, according to The Wall Street Journal.
“You’re capturing real-time data at every point, on every single food product,” Frank Yiannas, vice president of food safety at Walmart, was quoted saying about the use of blockchain technology. “It’s the equivalent of FedEx tracking for food.”
Besides Walmart, the Food Trust includes Nestle, Dole Food, Driscoll’s, Golden State Foods, Kroger, McCormick, McLane, Tyson Foods and Unilever. The trust is using technology from IBM to so far store data on one million items in about 50 categories. Read more here.
