ServSafe Foodborne Illnesses and Allergens 5 — Questions and Answers
Question 1: Which foodborne pathogen is described as intracellular and particularly dangerous for pregnant women, the elderly, and immunocompromised individuals?
- Campylobacter jejuni
- Listeria monocytogenes (Correct answer)
- E. coli O157:H7
- Clostridium perfringens
Correct answer: Listeria monocytogenes
Listeria monocytogenes can survive refrigeration temperatures and is especially dangerous for at-risk populations, potentially causing miscarriage or meningitis.
Question 2: A guest with a wheat allergy orders gluten-free pasta. The cook uses the same pasta water that was used for regular pasta. This practice is:
- Acceptable if the water is boiling
- Unacceptable because it causes allergen cross-contact (Correct answer)
- Acceptable if enough water is used
- Unacceptable only if the guest has celiac disease
Correct answer: Unacceptable because it causes allergen cross-contact
Shared pasta water contains wheat proteins, which can cause an allergic reaction regardless of water temperature or volume.
Question 3: Which symptom is MOST associated with shellfish or peanut allergic reactions and can be life-threatening?
- Nausea and vomiting
- Anaphylaxis (Correct answer)
- Watery diarrhea
- Jaundice
Correct answer: Anaphylaxis
Anaphylaxis is a severe, rapid allergic reaction that can cause throat swelling and cardiovascular collapse, requiring immediate epinephrine treatment.
Question 4: Hemolytic Uremic Syndrome (HUS), a potentially fatal kidney complication, is most commonly linked to which pathogen?
- Hepatitis A
- Shigella spp.
- E. coli O157:H7 (Correct answer)
- Vibrio vulnificus
Correct answer: E. coli O157:H7
E. coli O157:H7 produces Shiga toxins that can cause HUS, especially in children, leading to kidney failure.
Question 5: What is the correct action when a guest informs staff of a food allergy AFTER ordering but before the food is prepared?
- Proceed with the original order since it has already been placed
- Inform the manager and kitchen, remake the item safely using allergen-free ingredients (Correct answer)
- Offer to remove the allergen from the plate before serving
- Ask the guest if they have their own medication before deciding
Correct answer: Inform the manager and kitchen, remake the item safely using allergen-free ingredients
The kitchen and manager must be notified immediately so the dish can be prepared safely using clean equipment and allergen-free ingredients.
Question 6: A large batch of cooked chicken soup is left at room temperature for 5 hours. Which pathogen is MOST likely to pose a risk due to spore germination and rapid multiplication?
- Hepatitis A
- Clostridium perfringens (Correct answer)
- Norovirus
- Listeria monocytogenes
Correct answer: Clostridium perfringens
Clostridium perfringens spores survive cooking, germinate as food cools slowly, and multiply rapidly in the temperature danger zone.
Question 7: Under the FDA Food Code, which of the following is required on a menu or menu board to help protect guests with allergies?
- A full ingredient list for every dish
- A disclosure statement directing guests with allergies to inform their server (Correct answer)
- Separate allergen-free menus for each of the Big 9 allergens
- Calorie counts alongside allergen icons
Correct answer: A disclosure statement directing guests with allergies to inform their server
The FDA Food Code requires a consumer advisory on menus advising guests with food allergies to notify staff before ordering.
