1. Food spoilage organisms
Lesson objective – to understand the conditions that cause food spoilage

2. Questions Do you know when food spoilage may occur?
What is physical contamination?
How could transportation affect food?
What is the average shelf life of fresh food?
Lesson objective – to understand the conditions that cause food spoilage

3. Micro-organisms Yeasts Mounds Bacteria
Task 1 – find out what all three of these mean
Lesson objective – to understand the conditions that cause food spoilage

4. Did you know? Ion order to grow and multiply micro-organisms you need:
Warmth\moisture
Food supply
Time
Air\neutral pH
If one or more of these conditions is removed then growth of micro-organisms is slowed
Lesson objective – to understand the conditions that cause food spoilage

5. Task 2
Go onto the internet and copy and paste a temperature control that shows the prevention of food spoilage indicators
Task 3
Now read the case study on page 79 and answer the questions 1-2-3
List what micro organisms are (all three)
What does aerobic bacteria need to grow?
Wht does Anaerobic bacteria need to grow?
Lesson objective – to understand the conditions that cause food spoilage
