the solution of traceability in food industry

Today, consumers tend to focus on personal health and safety and realize the environmental impact. The
research from the Krungthai COMPASS research center shows that Thai agri-food must prepare for new
standards or regulations. Especially about food traceability, related to consumer needs, by using tag or label
to collect the data from farm to fork, e.g., RFID tag. Researchers predict that Thai agri-food in these categories
must develop traceability technology as soon as possible, such as livestock, fishery, fruit & vegetable, and
animal feed. These products mainly rely on the European and USA market, which is 16% of Thai agri-food
export income or around 159,000 million baht per year.
