Blockchain and what it has to do with lettuce and food safety

Blockchain is the technology and the approach that allows people to share a database, which is duplicated through a network of many, many, many computers and other devices. This is different from a traditional database that is centrally located, owned by a person or organization, and therefore more easily hacked or corrupted.

Instead, anyone across the network can provide information to this database without losing ownership of this information and at the same time benefit from all the information in the database.

So, what would the blockchain have to do with food security? Initiatives such as the IBM Food Trust are trying to use blockchain to help improve food security, which has been a particularly important issue this year. Since public health officials were not initially able to determine the specific sources of contamination of the Escherichia coli O157: H7 epidemic-associated with Roman lettuce-, Centers for Disease Control and Prevention began by warning the user to avoid all lettuces.

According to forbes.com¸, public health officials have scaled down warnings on Roman lettuce and are now focusing on Roman lettuce from California. These 2 outbreaks are part of the worst year for the outbreaks of infectious diseases brought by multistate foods reported in recent memory, according to the lists of Centers for Disease Prevention and Control (CDC).
