Blockchain Grocery: How Walmart Delivers Food Safety

Quartz: “Thanks to technology originally designed to monitor cryptocurrency … something that could put a significant dent in the number of foodborne illnesses that occur every year. It’s part of a new program in which IBM is partnering with Walmart, Nestlé, Dole, Tyson Foods, Kroger, and others, to use blockchain technology to track food throughout the complex global supply chain.”

“Under the new system, if a consumer falls ill from E. coli traced to a batch of lettuce, a food-safety investigator could conceivably scan a barcode on the packaging to quickly learn where it came from and where other lettuce from the same batch went. Retailers will be able to quickly remove contaminated products from shelves, thus stopping the spread of illnesses.”

“Walmart has been using a pilot version of the technology, showing how blockchain can be expanded beyond the financial, health care, and natural resources sectors to be applied to the foods that consumers interact with every single day. Coupled with companies’ efforts to stop food-borne illnesses early on, this could signal a major moment in how humans keep the food system in check.”
