US: Walmart Demands Salad Growers Use Blockchain for Food Safety
Yahoo! Finance: Walmart has advised its fresh, leafy greens producers to use blockchain technology to trace the movement of their products under its food traceability initiative, and to have all systems in place about one year from now, according to the company’s website.
A letter to its suppliers noted the U.S. has suffered a multi-state outbreak of E coli linked to romaine lettuce, resulting in 210 confirmed cases, 96 hospitalizations and five deaths. Blockchain technology will make product information available in real-time throughout the supply chain from farm to table.
