Abstract
The main aim of this paper was to revisit scientific manuscripts and identify key food safety performance indicators that may be applicable in different types of food company. A total of 48 papers has been analyzed, and results show that indicators may be categorized as process-based, product-based, and company-based performance indicators. Process-based indicators analyzed the effectiveness of processes found in a majority of food companies such as hygiene, control, maintenance, storage, purchasing, and human resources. Product-based indicators were analyzed through the perspective of production effectiveness as the core process in all food companies. Company-based indicators were deployed in terms of indicators used to verify the effectiveness of the food safety system.
