Fall Semester 2026 | 400 Verified Questions & Detailed RATIONALE
Q1. According to the U.S. Food Allergen Labeling and Consumer Protection Act
(FALCPA), how many major food allergens are recognized?
A. 6 B. 7 C. 8 D. 9 E. 14
CORRECT ANSWER: D. 9
RATIONALE: FALCPA originally identified 8 major allergens. In 2023, sesame was
added as the 9th major allergen under the FASTER Act, bringing the total to 9: milk,
eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame.
Q2. Which of the following is NOT classified as one of the 9 major food allergens
under U.S. law?
A. Sesame B. Shellfish C. Mustard D. Tree nuts E. Soybeans
CORRECT ANSWER: C. Mustard
RATIONALE: Mustard is recognized as a major allergen under European Union
law (EU 14 allergens) but is NOT among the 9 major allergens recognized under U.S.
FALCPA/FASTER Act legislation.
Q3. The European Union recognizes how many major food allergens that must be
declared on food labels?
A. 9 B. 10 C. 12 D. 14 E. 16
CORRECT ANSWER: D. 14
RATIONALE: The EU Food Information for Consumers Regulation (EU FIC No.
1169/2011) mandates declaration of 14 allergens: celery, cereals containing gluten,
,crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans,
sulphur dioxide/sulphites, and tree nuts.
Q4. Which protein in peanuts is most commonly associated with severe allergic
reactions?
A. Ara h 1 B. Ara h 2 C. Ara h 8 D. Ara h 9 E. Ara h 6
CORRECT ANSWER: B. Ara h 2
RATIONALE: Ara h 2 is considered the most potent peanut allergen and is most
strongly associated with severe and systemic allergic reactions, including anaphylaxis. It
is highly resistant to digestion and heat processing.
Q5. Peanuts are botanically classified as which of the following?
A. Tree nuts B. Seeds C. Legumes D. Grains E. Tubers
CORRECT ANSWER: C. Legumes
RATIONALE: Despite their name, peanuts are legumes (Arachis hypogaea),
belonging to the same plant family as soybeans, lentils, and peas — not tree nuts.
However, people allergic to peanuts may also react to tree nuts due to cross-reactivity.
Q6. Which of the following tree nuts is most commonly implicated in severe
allergic reactions?
A. Macadamia B. Pistachio C. Cashew D. Walnut E. Chestnut
CORRECT ANSWER: C. Cashew
RATIONALE: Cashew allergy is among the most common and severe tree nut
allergies. Cashew and pistachio belong to the same botanical family (Anacardiaceae)
and cross-reactivity between them is very common. Cashew allergy is increasingly
prevalent, particularly in children.
Q7. Gluten is found in which of the following grains?
A. Rice B. Corn C. Wheat D. Millet E. Quinoa
, CORRECT ANSWER: C. Wheat
RATIONALE: Gluten is a protein composite found in wheat (and related grains like
barley and rye). Rice, corn, millet, and quinoa are naturally gluten-free grains, although
cross-contamination during processing can introduce gluten.
Q8. Which allergen was added to the U.S. major allergen list by the FASTER Act,
effective January 1, 2023?
A. Mustard B. Lupin C. Sesame D. Molluscs E. Celery
CORRECT ANSWER: C. Sesame
RATIONALE: The Food Allergy Safety, Treatment, Education, and Research
(FASTER) Act was signed into law in April 2021, officially making sesame the 9th major
food allergen in the United States, effective January 1, 2023.
Q9. Which of the following is a common hidden source of milk protein in food
products?
A. Casein B. Lecithin C. Pectin D. Starch E. Xanthan gum
CORRECT ANSWER: A. Casein
RATIONALE: Casein is a milk protein used as a food additive and ingredient in
many products (e.g., non-dairy creamers, deli meats, cereals). It must be declared on
labels under FALCPA. Lecithin often comes from soy or sunflower, not milk.
Q10. Which of the following foods is considered both a legume AND a major food
allergen in the U.S.?
A. Lentil B. Chickpea C. Soybean D. Green pea E. Lupin
CORRECT ANSWER: C. Soybean
RATIONALE: Soybeans are legumes and are officially designated as one of the 9
major food allergens under U.S. FALCPA. While lentils, chickpeas, peas, and lupin are
also legumes, they are not classified as major allergens under U.S. law.
, Q11. Lactose intolerance and milk allergy are different conditions. Which
statement best describes a milk allergy?
A. A digestive response to lactose sugar in milk B. An immune-mediated reaction to milk
proteins C. A deficiency in lactase enzyme production D. A psychological aversion to
dairy products E. A sensitivity to milk fat content
CORRECT ANSWER: B. An immune-mediated reaction to milk proteins
RATIONALE: Milk allergy is an immune system response to milk proteins (casein
and whey), potentially causing anaphylaxis. Lactose intolerance is a digestive issue
caused by insufficient lactase enzyme to break down lactose sugar — it is
uncomfortable but not life-threatening.
Q12. Which of the following fish is specifically listed as a major allergen under
U.S. FDA guidelines?
A. Shrimp B. Lobster C. Salmon D. Crab E. Oyster
CORRECT ANSWER: C. Salmon
RATIONALE: The FDA lists specific finfish including salmon, tuna, tilapia, bass,
cod, flounder, grouper, haddock, halibut, mahi-mahi, perch, pike, pollock, snapper,
swordfish, and trout as major allergens. Shrimp, lobster, crab, and oyster are classified
under shellfish — a separate allergen category.
Q13. Cross-reactivity between shrimp and which of the following is most likely
due to shared tropomyosin protein?
A. Salmon B. Oyster C. Crab D. Tilapia E. Sardine
CORRECT ANSWER: C. Crab
RATIONALE: Tropomyosin is the major allergen in crustacean shellfish. Shrimp
and crab belong to the same crustacean family and share highly similar tropomyosin
proteins, making cross-reactivity very common. Oyster is a mollusc, not a crustacean.
Q14. Which of the following statements about egg allergy is correct?
