According to the letter sent to the suppliers, any company supplying Walmart with leaf greens must work on the IBM Food Trust network to ensure end-to-end traceability of its products. The blockchain platform will allow to establish the origin of such products quickly, while in the current conditions this "task is practically irresolvable".

Earlier experts of the Center for Disease Control warned citizens about the danger of eating a salad grown near the town of Yuma, Arizona. Walnart's vice president of food safety Frank Yiannas said that now customers can hardly determine where the products they offered were manufactured.

But it was difficult for consumers to know how to determine where their lettuce was grown. None of the bags of salad had ‘Yuma, Arizona’ on them. In the future, using the technology we’re requiring, a customer could potentially scan a bag of salad and know with certainty where it came from.

The first phase of the program involves ensuring "one-step traceability" by direct suppliers by the end of January. Other companies that perform the role of intermediaries should implement the system integration until the end of September next year across the vertical.
