An increasing number of experts warn that food fraud quietly siphons off up to $50 billion annually from the global food industry, posing serious health risks to consumers as well. Industry insiders suggest that blockchain technology could be a solution to prevent counterfeit and adulterated products. However, deploying such systems throughout complex supply chains requires substantial investment and careful strategy. The Impact of Food Fraud Food fraud involves deceiving buyers about the contents of their food. It ranges from mixing inexpensive oils into olive oil to adding hazardous substances like melamine to milk. For instance, a 2008 milk scandal in China reportedly caused illness in over 300, 000 infants. Defined by the UN Food and Agriculture Organization, food fraud is the intentional act of misleading consumers regarding the quality or ingredients of purchased food. Although food fraud represents only a small portion of the $12 trillion food sector, its economic impact rivals that of a country like Malta. Consumer trust diminishes, brands suffer, and even legitimate farms and shops face repercussions during fraud scandals. Recent instances of food fraud have been documented across Asia and the Pacific.

Walmart, for example, has used Hyperledger Fabric to trace pork in China and mangoes in the US, reducing tracking time from days to seconds. This allows immediate identification of contaminated products entering the supply chain. Once entered, data on the blockchain cannot be altered or deleted, providing consumers and inspectors with an unchangeable record from farm to fork. Tech experts believe that such transparency deters fraudsters who depend on secrecy. Authorities describe food fraud as the intentional misrepresentation of food products—whether by adding cheaper ingredients, substituting inferior items, or falsifying labels—to deceive consumers for financial gain.

Companies face costs for software, hardware, training, and sensors needed to input data into the blockchain.

Faulty or tampered devices can compromise data integrity. Oracles connecting real-world events to the blockchain are vulnerable to hacking. Additionally, some businesses hesitate to share detailed information due to competitive concerns. Regulations regarding blockchain and food traceability remain unclear in many regions. Coordinating all players—from farmers and shippers to retailers—requires significant time and financial resources. Estimates suggest that launching a large-scale system can cost millions of dollars for major stakeholders. Advancing Adoption Organizations like TE-Food and Provenance, along with industry groups, are conducting pilot projects involving farmers, distributors, and retailers to test blockchain applications. Training programs are in progress. Certain governments in the EU and Asia are discussing clearer regulations on food traceability. Experts recommend beginning with small-scale projects focused on specific products or regions to demonstrate value quickly. Successful pilots could encourage wider participation. Looking Forward Food fraud persists as a significant challenge. While tools like blockchain offer real potential to combat it, they carry steep costs. Effective use of blockchain requires addressing weaknesses in cold-chain monitoring, bridging data silos, and establishing regulatory clarity. Investment in reliable sensors, secure oracles, and strong collaborations is essential. When these elements align, blockchain could substantially reduce food fraud. Until then, protecting consumers and securing the food supply remains a demanding endeavor. Featured image courtesy of SafeFood; chart sourced from TradingView.
