One day you are eating a juicy pork burrito and the next you are turned over with stomach cramps and bloody diarrhea [1]. You have E. Coli. E. Coli can kill you. <\/span><\/p>\n In January 2016, the Center for Disease Control reported that at least 55 people were infected with an outbreak of E. Coli caused by food at Chipotle Mexican Grill [2]. After a thorough investigation of Chipotle\u2019s supply chain, the U.S. Food and Drug Administration <\/span>was not<\/span><\/i> able to identify the origin of the outbreak [2]. Chipotle closed 43 restaurants in Washington and Oregon [2] and their stock tumbled over 44% [3].<\/span><\/p>\n Food supply is no easy business and the risk of a foodborne disease outbreak weigh heavy on any food supplier. Walmart, which runs a complex network of farmers, brokers, distributors, processors, retailers, and regulators, to deliver food to over 290 million consumers per week, does not want to become the next Chipotle [4]. Walmart\u2019s management team is experimenting with Blockchain technology to bring transparency to the flow of the food in their supply chain and prevent a foodborne illness emergency [5].<\/span><\/p>\n Blockchain, the open source technology underpinning Bitcoin, is a distributed ledger and can be used to augment a supply chain\u2019s database management system. Blockchain provides a supply chain with three core value propositions: decentralization, verification, and immutability [6].<\/span><\/p>\n Together these three value propositions bring reliability<\/em> and transparency<\/em> to the supply chain in a way that has never been available before. Blockchain creates a shared forum for all supply chain members to see the flow of inventory as soon as the inventory moves from one location in the chain to another. <\/span><\/p>\n In 2016, Walmart partnered with IBM to implement Blockchain in a test pilot. Before starting the pilot, Walmart executives took a box of Mangoes from a store location and asked their team to find where the mangoes came from. It took the team six days, 18 hours and 26 minutes to find the Mangoes\u2019 origin [5]. There was a lot of room for improvement. <\/span><\/p>\n Walmart implemented Blockchain by scanning each palette of Mangoes as they move through the supply chain: from farmer to processor to distributor, and eventually, to the retail location. At each checkpoint the palettes were recorded in the Blockchain. IBM built the cloud infrastructure and front end application to monitor the Mangoes as they moved through the chain. <\/span><\/p>\n After successfully implementing, Walmart executives took a box of Mangoes to their latest shareholder meeting. They demonstrated finding the origin of the Mangoes in two seconds [5]. <\/span><\/p>\n Using Blockchain technology, Walmart management created an immediate view into the flow of their food supply. Regulators can now use this data to quickly identify the origins of food outbreaks [5]. Without Blockchain technology it took the team over six days. With Blockchain it took two seconds.This is the difference between a Chipotle level emergency and completely containing a disease outbreak. <\/span><\/p>\n
