Chapter 8 - Introduction To Food Safety Flashcards
Explain the difference between food borne illness and a food outbreak:
An illness is carried or transmitted to people by food.
An outbreak is when two or more people get sick after eating the same contaminated food.
What type of impact does foodborne illness/food outbreak have on a restaurant?
Foodborne illness can: Lead to a loss of customers and sales Lead to a loss of prestige and reputation Cause negative media attention Lead to legal suits resulting in lawyer and court costs Lead to increased insurance premiums Lead to lowered employee morale Lead to employee absenteeism Lead to staff retraining
What are microorganisms?
Living, single celled organisms that cause food spoilage and illness and can be transferred from hands and surfaces to other food and surfaces.
Bacteria . . .
Multiply rapidly in food, produce toxins in food
Virus . . .
Do not grow in food, but can be transported on food
Parasites . . .
Are organisms that need to live inside a host to survive.
Fungi . . .
Molds are highly adaptable organisms that grow quickly.
Yeast is a type of fungus that needs sugar and moisture to survive.
Toxins . . .
Are carried by some fish.
Barriers to bacterial growth (FAT TOM):
Food
Acidity - high acidity is good
Temperature - 41 to 135 Fahrenheit is danger zone
Time - 4 hours
Oxygen - most bacteria need it
Moisture
Name some potentially hazardous foods:
Potatoes, sprouts, ham, eggs, tofu, watermelon, turkey, dairy, rice
Name some chemical hazards:
Cleaning supplies, pesticides, metal poisoning (acid and lead, copper, brass, or zinc)
Name some physical hazards:
Glass, metal shavings, toothpicks, staples, jewelry, pastry brushes
How do food handlers contaminate food?
Having a food borne illness
Having wounds
Having contact with a person who is ill
Touching hair, face, body
Touching anything that may contaminate their hands
Having symptoms of illness
Eating, drinking, smoking or chewing gum while preparing or serving food
How long should you wash your hands in hot soapy water?
At least 20 seconds
What is cross contamination?
When microorganisms are transferred from one surface to another
How can one prevent cross contamination?
Sanitize work station, cutting boards, and utensils
Don’t allow ready to eat food to touch raw meats, seafood, or poultry
If using the same table to prep raw and ready to eat food, sanitize between each product
What is FIFO?
First In First Out
What is HACCP?
Hazard Analysis Critical Control Point
List the 7 HACCP principles:
- Assess hazards (recipes, employee process, temperature, customers, suppliers, size of operation, employees, flow of food - every step of the way.
- Identify critical control points (prevent contamination, prevent contaminants from surviving, prevent further growth of contaminants)
- Setup procedures for CCP (observe/measure, wash hands, wash surfaces, cook thoroughly, hold food above 135, cool food rapidly, reheat properly)
- Monitor CCP - who and how often
- Take corrective action - heat food, throw out, reject shipment
- Verify the system works - check logs, observe employees
- Establish procedures for record keeping and documentation
What is the difference between a clean surface and a sanitary surface?
Clean surface = free of visible soil, such as dirt, dust, and surface food waste
Sanitary surface = reducing the number of microorganisms on a clean surface to safe levels
What people fall into the category of high-risk populations?
Elderly people
Infants and pre-school age children
Pregnant women
People with cancer, HIV/AIDS, transplant recipients and others with compromised immune systems
What is a hazard?
Something with the potential to cause harm.
What is contamination?
When harmful things are present in food, making it unsafe to eat.
What are pathogens?
The microorganisms that cause illness, from your body to food.
What is Time Temperature Abuse?
When food stays too long at temperatures that are good for pathogen growth.
What is cross contamination?
The transfer of pathogens from one surface or food to another.
