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

Abstract

Blockchain technology, initially applied to the fi nancial market, is recognized for its security in storing information
in a decentralized manner and its ease of access to this information. An application of blockchain technology is the establishment of
traceability systems for production chains. Food traceability systems are becoming increasingly important in guaranteeing the quality
and safety of food to the fi nal consumer, who, in turn, values and exercises confi dence in the traceability system, recognizing its
importance. This study was conducted to provide a systematic literature review on the importance of applying blockchain technology to
the traceability of products of animal origin. Two scientifi c databases were consulted: Scopus and Web of Science. After classifi cation
based 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 blockchain
technology in the traceability of products of animal origin is used in several production chains, providing consumers with long-awaited
information about the origin of their food such as beef, milk, fi sh, meat, pork, and eggs.
