An information System for Food Safety Monitoring in Supply Chains based on HACCP, Blockchain and Internet of Things
With the rapid growth of China's economy, people's living standard has been increased continuously, which changed the consuming habit of consumers, and more and more attention is paid to food safety and quality. However, in recent years, a series of serious food safety incidents occurred, such as "Sudan red" "clenbuterol" "Sanlu toxic milk powder" and "trench oi" It is worth noting that not only in China, but even in Europe these kinds of scandals have broken out during the past 20 years, including Escherichia coliin hamburgers, Salmonella in eggs, poultry and pork, Listeria in pates and cheeses, and the "horse meat scandal" in 2013. These food safety problems not only harm people's health, but also undermine their trust in food markets. The main purpose of this cumulative dissertation is trying to guarantee the food quality and safety from a supply chain management perspective, and the key issue is building a decentralized information system which is not dependent on the trust of a central authority or organization for the whole food supply chain. By using the internet of things and blockchain technologies, this new decentralized information system could become a disruptive innovation which could provide an information platform for all supply chain members (including government departments and third party regulators) based on openness, transparency, neutrality, reliability and security. We want to establish a food supply chain traceability system for real time food tracing, build a safety control system for food supply chain by integrating it with general supply chain risk management methods, and significantly improve the performance of the food logistics company. All of these will ultimately enhance the safety assurance of a food supply chain.
