Carrefour will track food supply with blockchain


Carrefour will use blockchain food tracking technology from IBM to track its food supply, starting with chicken and microgreens. According to, the platform to be used is the IBM Food Trust, hosted on the IBM Cloud.

Using food tracking, the retailer will place QR codes on the products, by scanning which customers will access information about their production process, all the way from farm to the store. The source says that customers will receive access to such information as the origin of the product, production date, transportation, ingredients and nutrition data, temperature, and health certifications.

IBM Food Trust is a platform that aims to improve supply chain efficiency, food safety, and brand trust. Thanks to the shared record of information about products, businesses and individuals can access the data they need to ensure transparency. Customers of the food-tracking platform include Walmart, Nestlé, Raw Seafoods, Tyson Foods, and a Tunisian olive oil company CHO.

Moreover, several other olive oil producers are using the platform besides CHO. I Potti de Fratini, an Italian oil mill, also uses the service, along with a Spanish producer Conde de Benalua and an Argentinian supplier Rolar de Cuyo, who joined in November 2020 as per the press release.
