Development of Key Processes along the Supply Chain by Implementing the ISO 22000 Standard

The aim of the article is to answer the question of whether the implementation of the requirements of the ISO 22000 standard in the food supply chain can support the implementation of key processes occurring in them, and thus increase the level of food quality and minimize its waste. The research was conducted out among several European countries, and an attempt was carried out to compare how the standard is perceived by entrepreneurs operating in Poland, Slovakia (Central and Eastern Europe), and Portugal (Western Europe). Covering the Polish, Slovak, and Portuguese organizations with the research process resulted from the fact that in recent years in these countries, an increase in the diversity of food demand and fragmentation of the food market has been observed. This forced food supply chains to be strictly focused on increasing the efficiency and effectiveness of production and distribution systems, as well as taking into account customer requirements and the implementation of sustainable solutions. Based on the results of the research, it can be concluded that the implementation of the requirements of the ISO 22000 standard along food supply chains can positively affect the implementation of key processes and thus contribute to reducing food waste at each stage of the supply chain.
