European Grocer Carrefour Expands Blockchain Solution For Food Traceability

Carrefour, Europe’s largest public grocer by sales, has announced that it would expand its blockchain food traceability system to eight other products.

The company is currently using the blockchain system to trace the production of free-range chicken in the Auvergne region in central France. It will be rolled out to eight more animal and vegetable product lines, such as eggs, cheese, milk, oranges, tomatoes, salmon and ground beef steak. Carrefour aims for the tracking system to be in place by the end of the year.

Carrefour said that its blockchain food traceability system has been designed to guarantee complete product traceability. All parties involved in the supply chain (producers, processors and distributors) would be able to provide traceability information about their particular role and for each batch (dates, places, farm buildings, distribution channels, potential treatments, etc.)

Every product’s label will feature a QR Code which consumers will be able to scan using their smartphones. With this, they will get information about the product and the journey it has taken – from where it was reared right up to when it was placed on the shelves.

“For example, for free-range Carrefour Quality Line Auvergne chicken, consumers will be able to find out where and how each animal was reared, the name of the farmer, what feed was used (whether or not they were fed on French cereals and soya beans, on GMO-free products, etc.), what treatments were used (antibiotic-free, etc.), any quality labels, where they were slaughtered, etc.”

Laurent Vallée, Carrefour’s general secretary and head of quality and food safety, said the blockchain food traceability system is a first in Europe and will provide consumers with guaranteed complete transparency as far as the traceability of their products is concerned.

The company is also currently conducting blockchain tests to improve tracing the source of food products in China and could expand it to other countries.

Last year, IBM partnered with Nestle, Unilever, Tyson Foods and other large food and retail companies to explore how blockchain technology can help track food supply chains and improve safety.
