**1. Introduction**

On a global scale, there has been a notable elevation in the extent of foodborne diseases, in addition to disturbances in the international food trade resulting from recurrent disputes with regards to food safety requirements. In order for improvements to be recognized in food safety systems, most of these systems need to be reviewed and further developed. It is especially crucial at the present time, for both developed and developing countries, to create and propagate food safety systems in accordance with the principals of risk-based thinking and risk assessment. Therefore, it is important to be equipped with important knowledge on the principles and practices of food safety systems and the trend that will take food processors away from a merely reactive approach to food safety procedures, to a more proactive one.
