ServSafe Food Contamination and Allergens 4 — Questions and Answers
Question 1: A customer tells a server they have a tree nut allergy. The chef confirms the dish contains coconut. What should the server do?
- Inform the customer that coconut is a fruit, not a tree nut
- Alert the customer and offer an allergen-free alternative (Correct answer)
- Remove the coconut pieces from the dish before serving
- Check whether the customer is severely allergic before deciding
Correct answer: Alert the customer and offer an allergen-free alternative
Coconut is classified as a tree nut by the FDA, so the server must alert the customer and offer a safe alternative.
Question 2: Which of the following is an example of chemical contamination in food?
- Salmonella transferring from raw chicken to salad
- Sanitizer residue left on a cutting board used to prep vegetables (Correct answer)
- A hair falling into soup during plating
- Hepatitis A virus on unwashed hands touching ready-to-eat food
Correct answer: Sanitizer residue left on a cutting board used to prep vegetables
Sanitizer residue left on food-contact surfaces is a chemical contaminant that can transfer to food.
Question 3: What is the PRIMARY reason gluten-free dishes must be prepared with dedicated utensils?
- Gluten causes bacterial growth on shared utensils
- Even trace amounts of gluten from cross-contact can harm celiac patients (Correct answer)
- Gluten-free foods spoil faster when mixed with regular flour
- Health codes require color-coded utensils for all special diets
Correct answer: Even trace amounts of gluten from cross-contact can harm celiac patients
For people with celiac disease, even trace gluten from cross-contact on shared utensils can trigger a serious immune response.
Question 4: A food handler notices a bag of flour has a small hole and pest droppings nearby. This is BEST classified as what type of contamination risk?
- Chemical contamination from pest repellent
- Biological contamination from pest feces (Correct answer)
- Physical contamination from the bag material
- Radiological contamination from warehouse storage
Correct answer: Biological contamination from pest feces
Pest droppings contain bacteria and other pathogens, making this a biological contamination risk.
Question 5: Which allergen is most commonly hidden in Worcestershire sauce, requiring special attention when preparing dishes for allergic guests?
- Soy
- Wheat
- Fish (anchovies) (Correct answer)
- Milk
Correct answer: Fish (anchovies)
Worcestershire sauce traditionally contains anchovies, making it a hidden source of fish allergen.
Question 6: A manager suspects physical contamination occurred in a batch of soup. Which action should be taken FIRST?
- Strain the soup through a fine mesh and return it to service
- Remove the soup from service and discard it (Correct answer)
- Heat the soup to kill any physical contaminants
- Add more liquid to dilute the foreign object risk
Correct answer: Remove the soup from service and discard it
Food suspected of physical contamination must be removed from service and discarded to protect guests from injury.
Question 7: Which practice BEST prevents allergen cross-contact when plating food?
- Using the same tongs for all dishes but wiping between uses
- Changing gloves and using clean utensils before handling allergen-free orders (Correct answer)
- Plating allergen-sensitive dishes last so they are freshest
- Keeping allergen-free dishes covered until the customer sits down
Correct answer: Changing gloves and using clean utensils before handling allergen-free orders
Changing gloves and using sanitized, dedicated utensils prevents allergen proteins from transferring to allergen-free dishes.
