Food safety Flashcards
Why do we study food safety?
To maintain guest safety, to avoid the loss of business, to avoid law suits, to maintain the guests’ trust, and to maintain quality standards.
Food safety is a scientific discipline describing:
•
•
•
•
Of food in ways that prevent food borne illness.
Handling, preparation, storage, and serving.
Refers to foods that are spoiled or tainted because they either contain microorganisms or toxic substances that make them unfit for consumption.
Food contamination
The causes of food contamination:
Physical, chemical, biological, and microbiological.
Objects that get into the food during preparation or serving.
Physical contamination
Detergents, pesticides, water, and air.
Chemical contamination
Several insects may transfer food poisoning bacteria to food.
Biological contamination
This is present when we add raw material or when we have improper handling.
Microbiological contamination
Reproduction of bacteria
Food, acidity, temperature, time, oxygen, and moisture.
Bacteria require a high protein, high carbohydrate food source.
Food
Foods that are acidic or slightly neutral.
Acidity
Bacteria rapidly reproduce between 5 - 60°C. THE DANGER ZONE
Temperature
Given enough time in the danger zone range, bacteria will start rapidly reproducing.
Time
There are certain bacteria that require oxygen to reproduce and we call it aerobic bacteria.
Oxygen
Bacteria require moist food to reproduce.
