Walmart and other major fresh food suppliers are taking a major step to alleviate a perennial crisis – contaminated food. hey are implementing a blockchain network that tracks fruits and vegetables from farm to store. The software has reduced the time it takes to find the origin of injurious product from seven days to 2.2 seconds. Moreover, it cuts down on the wastage of food that has been the answer to contamination up to the present. If romaine lettuce caused illness, stores would remove all romaine from their shelves even though most of it was OK. Now, they will only trash that which has been identified as the source of illness. This will save time, injury and money. It will also make PR practitioners’ lives easier in managing communications for recalls. The new system is easier all the way around. Kudos to all the companies that have made this possible.
