The 2hr/4hr rule is a guideline for safely cooling hot food to prevent foodborne illness. It states that hot food must be cooled from 60°C (140°F) to 21°C (70°F) within two hours and then from 21°C (70°F) to 5°C (41°F) or below within a further four hours. This means you have a total of six hours to cool hot food to a safe refrigerator temperature. Adhering to this rule ensures that food spends minimal time in the temperature danger zone (5°C-60°C), where harmful bacteria can grow rapidly.
