Blockchain applied to the traceability of animal products: a systematic literature review

Blockchain technology, initially applied to the fi nancial market, is recognized for its security in storing informationin a decentralized manner and its ease of access to this information. An application of blockchain technology is the establishment oftraceability systems for production chains. Food traceability systems are becoming increasingly important in guaranteeing the qualityand safety of food to the fi nal consumer, who, in turn, values and exercises confi dence in the traceability system, recognizing itsimportance. This study was conducted to provide a systematic literature review on the importance of applying blockchain technology tothe traceability of products of animal origin. Two scientifi c databases were consulted: Scopus and Web of Science. After classifi cationbased on the inclusion and exclusion criteria, 12 articles were selected for the study. The application of blockchain technology is recent,emerging, and promising in the traceability of animal products, and it has attracted research interest worldwide. The use of blockchaintechnology in the traceability of products of animal origin is used in several production chains, providing consumers with long-awaitedinformation about the origin of their food such as beef, milk, fi sh, meat, pork, and eggs.
