-Format: Multiple-choice / Flashcard
Question 1: 3 Types of Contamination
Answer:
- Biological
:Pathogens- bacteria, viruses, parasites and fungi

- Physical

-Milk -Eggs -Fish -Shellfish -Wheat -Soy -Peanuts -Tree Nuts
Question 3: Viruses
Answer:
-Carried by humans and animals; -Usually transferred to food by human contact (fecal-oral route); -Not destroyed by normal cooking temperatures -Good personal hygiene is the most important way to prevent illness, but quick clean-up of vomit is also important
Question 4: FATTOM
Answer:
Conditions that support the growth of bacteria Food-Protein or Carbohydrates- commonly referred to as TCS foods Acidity-4.6 to 7.5 pH- neutral to slightly acidic Time-4 hours or less (there are a few exceptions) Temperature- 41°F to 135°F- rapid growth occurs
70°F-125°F
Oxygen- some bacteria need oxygen, other grow without it Moisture- .85 aw or above (water is 1.0 aw) (in short term, FATTOM stands for Food, Acidity, Time, Temperature, Oxygen and Moisture.)
Question 5: Yeasts
Answer:
Spoil food rapidly/ acidic foods/ smell of alcohol and a pink discoloration or slime
Question 6: Fungi
Answer:
Molds and Yeasts (acidic foods with low water activity)
Question 7: Pathogen
(Biological)
Answer:
Disease causing microorganism
Question 8: Foodborne Illnesses Caused By Bacteria: Shigella
Answer:
Sources: Found in the feces of humans with the
illness
Foods commonly linked are:
-Foods that are in contact with contaminated (fecal matter) water like produce -and food that is easily contaminated by hands, such as salads containing TCS food.
Prevention Measures:
-Exclude food handlers who have diarrhea -Wash hands
-CONTROL FLIES
Question 9: Foodborne Illnesses Caused By Bacteria: Salmonella Typhi
Answer:
Sources: People with typhoid fever carry it in their
bloodstream and intestinal tract.
Foods commonly linked are: RTE foods and
beverages
Prevention Measures:
-Wash hands -Cook food to minimum internal temperatures -Keep food handlers who are diagnosed with an illness caused by Salmonella Typhi out of the operation
Question 10: Microorganism
(Biological)
Answer:
Microorganism- Small, living organism only seen though a microscope Question 11: Foodborne Illnesses Caused by Viruses: Norovirus- #1 leading cause of foodborne Illness in the U.S
Answer:
Sources: Mainly found in the feces of infected people and in their vomit, it is EXTREMELY contagious
Foods commonly linked are: RTE foods and Shellfish from contaminated water
Prevention Measures:
-Exclude food handlers with vomiting or diarrhea -Wash hands -Avoid bare-hand contact with RTE foods -Purchase shellfish from approved reputable suppliers
Question 12: Molds
Answer:
can cause illness (poisons like aflatoxins) but mostly spoilage;
Question 13: Service Staff
Answer:
- Describe dishes
- Identify ingredients
- Suggest simple items
-Hand deliver food
Question 14: Physical Contamination
Answer:
-Hair -Nails -Metal shavings -Staples -Glass -Bones -Dirt, etc.
Question 15: Bacteria
Answer:
-Can be found almost anywhere; -Cannot be seen, smelled or tasted; -Can grow rapidly in correct FATTOM conditions -Controlling Time and Temperature is the most important way to prevent foodborne illness Question 16: Foodborne Illnesses Caused by Viruses: Hepatitis A
Answer:
Sources: Mainly found in the feces of people who are infected and water contaminated with that feces
Foods commonly linked are: RTE foods and Shellfish from contaminated water
Prevention Measures:
- Exclude food handlers with Jaundice
-Wash hands -Avoid bare hand contact -Purchase shellfish from approved reputable suppliers
