Lesson 1
The Cooling and Storage Cycle
Understand why rapid cooling is the most critical step in preventing food-borne illness.
Cooling Speed
Bacteria love lukewarm food. Never leave cooked dishes out on the side for hours. Aim to get food into the fridge within two hours of cooking. To speed this up, divide large portions into smaller, shallower containers, which allows heat to dissipate much faster than in one deep pot.
Airtight Environments
Once food has reached room temperature, seal it in airtight containers. This prevents fridge odours from being absorbed and stops your leftovers from drying out or being contaminated by raw foods in the fridge. Label every container with the date so you know exactly when it was made.
Storage Times
Most cooked leftovers should be consumed within 3 to 4 days. After this, even if the food looks and smells fine, the risk of hidden bacterial growth becomes too high for safety. Treat your fridge as a temporary holding area, not a permanent pantry.
