Recently, Bitcoin has brought to light blockchain technology, which offers great potential for food safety and verification in the food sector.
Simply put, blockchain technology is a way of storing and sharing information across a network of users in an open virtual space. Blockchain technology allows for users to look at all transactions simultaneously and in real-time. In food, for example, a retailer would know with whom his supplier has had dealings. Moreover, since transactions are not stored in any single location, it is almost impossible to hack the information.
For those who don’t know yet, here is a nice video where it is explained how blockchain works.
Some companies, such as Nestle, Unilever, and Dole, normally competitors, are coming together with Walmart to form a standard of using blockchain to ensure food safety. Your can read here the whole article.
Also, we could see here, explained by Frank Yiannas, Walmart’s Vice President of Food Safety, how this works:
This has obvious implications for food safety—when salmonella or other contaminants are discovered in an item, it would be simple to discover from where those items came and to which stores those items were sold, generating potential cost savings. But, as it is said in the video, traceability is not only the goal. The final goal is also to know how was this item produced.
Was it produced safely? Was it produced responsibly? Is it sustanaibley grown?
I would definitely spend few minutes to discover this while buying some products, would you?
