ISO 22000 is an international standard for Food Safety Management which is widely used by food businesses and handling staff to ensure the quality and condition of the food items. They are mostly adopted by food outlets to ensure compliance with norms set by the regulatory bodies.
Once implemented, there should be a Food Safety Policy prepared by the higher level management and steps should be taken to ensure proper communication channels between different levels of staff, suppliers and other parties involved. There should be a definite food safety objective that can be tracked at multiple levels to ensure the quality and hygiene condition in which food is passing through.
