Kroger is one of the largest grocery retailers in the US and, like any other food industry enterprise, there are many challenges that Kroger is facing and one of the biggest is traceability. Federal regulations are forcing companies to get an understanding of their entire supply chain, because ultimately they are going to need to not only know where they are getting the goods from and whether those goods are safe to eat, but they also need to know where exactly the good came from as well.

For Kroger, food recalls are quite costly because it often must pull unaffected product from the shelves. By implementing a Hyperleger blockchain with industry-specific IBM modules for food traceability, the retailer can work with suppliers to trace food from the farm to its shelves, helping it identify which products to pull, and which are safe for its customers.
