In response to food contamination scandals worldwide, retail giant Walmart is tackling food safety in the supply chain using blockchain technology. In 2016, it established the Walmart Food Safety Collaboration Center in Beijing and plans to invest $25 million over five years to research global food safety (Yiannas and Liu, 2017). Using IBM’s blockchain solution based on Hyperledger Fabric, Walmart has successfully completed two blockchain pilots: pork in China and mangoes in the Americas (IBM, 2017). With a farm-to- table approach, Walmart’s blockchain solution reduced time for tracking mango origins from seven days to 2.2 seconds and promoted greater transparency across Walmart’s food supply chain (Yiannas, 2017). IBM called it “complete end-to-end traceability”
I read the same article, but note-—
It was about Walmart CHINA—not USA. That is, pork SOLD in China uses the blockchain solution.
Frankly, I just do not want to eat meat grown, slaughtered and processed in any other country except the USA.
I’ll make exceptions for European cheeses, sardines and herring, German hams, and anything from Canada.
When I read a label on a food product and it says made/processed/canned in China, I do not buy.
