They wanted to eat healthily and fell ill. Almost 4,000 people who had prepared a salad in the summer of 2011 infected themselves with the gut germ EHEC, 53 even died. The danger ran rampant for a good two months before it became clear that bacterially contaminated fenugreek sprouts had come from Egypt to a dealer in the Lower Saxony Bienenbüttel and from there directly onto the plate.

According to the World Health Organization, more than 400,000 people die worldwide from contaminated or spoiled food. Opaque supply chains in a global food production aggravate the problem. In the future, blockchains should create more transparency and make trade even fairer and more sustainable. So at least the promises of IT companies, start-ups and food industry.

According to analysts at consulting firm Gartner, 20 percent of the world's top 10 grocers will use blockchain technologies by 2025. Together with Walmart, IBM has partnered with Walmart to develop a blockchain solution called "IBM Food Trust" that will help identify batches of spoiled merchandise faster, said Christian Schultze-Wolters, Business Unit Manager Blockchain Solutions, IBM. The open platform now includes companies such as Carrefour, Dole, Golden State Foods, Kroger, McLane Company, Nestlé, Tyson Foods and Unilever.
