Europe’s largest retailer Carrefour has adopted blockchain ledger technology to track and trace chicken, eggs and tomatoes as they travel from farms to stores, and will deploy it across all of its fresh product lines in coming years.
The French retail giant said it will rely on blockchain technology developed by IBM, which is working with a number of retailers, logistics firms and growers to roll out systems to secure their global supply chains.
IBM Food Trust allows the industry to track and share information on how products are grown, processed and shipped. The technology cuts the time for checking the provenance of food from days or weeks to seconds, IBM said.
Innovation leader in the mass distribution, Carrefour was the first firm to develop the #blockain in the food sector. It will be generalized to all products of Carrefour Quality Line by 2022. Transparency for confidence! #ActForFood #FoodTransition https://t.co/EK4An1KuEe pic.twitter.com/rUfOXHXUfa

Blockchain, best known as the technology underlying cryptocurrency bitcoin, is a shared record of data kept by a network of individual computers rather than a single party.
Proponents say it has the power to transform industries from finance to real estate, but so far there have been few examples of its large-scale application.
Carrefour Secretary General Laurent Vallee said the group would widen its use of the system to its 300 fresh products across the world by 2022, securing a safe supply chain and allowing customers to trust in their food.
“The key thing for us as Carrefour is to be able to say when there is a crisis that we have the blockchain technology, so we are able to trace products and tell the story of the products,” he told Reuters.
Outbreaks of salmonella linked to eggs and poultry are a major challenge for the food industry.
Nearly 207 million eggs from a North Carolina farm possibly contaminated with the organism were recalled in April, while the number of salmonella food poisoning cases in the European Union is rising.
Global businesses will pay around US$212,000 a year for full use of Food Trust, which is now available worldwide, IBM said.
Still, mass adoption of the technology could face hurdles, said Simon Ellis of US-based market research firm IDC.
“The efforts to convince growers to participate is not a minimal one,” he said. “Growers and farmers exist at dramatically different levels of technological sophistication.”
Pork processing giant Smithfield Foods is among other firms joining the project, IBM said, while science and technology companies contributing data to the blockchain now include Minneapolis-based 3M.
Walmart Inc said last month it would ask leafy greens suppliers to implement real-time, farm-to-store tracking using IBM’s technology.
Last year, 10 retail and food companies including Nestle, Unilever and Tyson Foods joined the project.
