What are the Big 9 food allergens on the ServSafe exam?

Milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Sesame was added to the federal major-allergen list in 2023, and current ServSafe materials test all nine. ServSafe sets its own question pool, so confirm with your current study materials.

Does cooking food destroy allergens?

No. Allergens are proteins, not pathogens. Cooking to 165F kills bacteria but does not make an allergen safe. Even trace residue on a shared pan can trigger a reaction, which is why allergen questions and temperature questions are answered differently.

Can sanitizing remove a food allergen?

Not on its own. Sanitizer kills microbes but does not reliably remove protein residue. The standard is wash, rinse, and sanitize with fresh gloves, clean utensils, and freshly cleaned prep surfaces. For a shared fryer, allergen proteins can carry over in the oil, so dedicated equipment is safer.

How many allergen questions are on the ServSafe Manager exam?

Allergens sit inside Contamination, Allergens & Pest Management, one of the heaviest domains on the 7th/9th edition blueprint. Expect roughly 8-10 questions in that domain, several of them allergen scenarios rather than list recall.

ServSafe Manager · the Big 9

The 9 food allergens you must know cold

Milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, sesame. Nine items, one trap: every other hazard on the exam is a microbe you can kill with temperature, sanitizer, or time. Allergens are proteins you cannot cook away, clean away, or dilute away. That single difference generates most of the allergen questions on the ServSafe Manager exam.

Big 9 count: 9 allergens (sesame added 2023)
Exam home: Contamination, Allergens & Pest Management
Kill by cooking?: No — proteins survive heat
Removed by sanitizer?: No — wash, rinse, sanitize
Key term: Cross-contact, not cross-contamination

The federal major-allergen list comes from FALCPA and the 2023 FASTER Act; ServSafe publishes its own study materials, so confirm the current edition's coverage when you study.

The list, grouped so it sticks

Memorizing nine loose words is fragile under exam pressure. Group them by where they show up in a kitchen and the list stops being arbitrary:

Group	Allergens	Memory hook
Animal	Milk, eggs, fish, shellfish	Cow to ocean — everything that swims or comes from an animal
Nuts	Peanuts, tree nuts	Two separate rows on the exam, one is a legume
Grain / seed	Wheat, soybeans, sesame	Three seeds the food industry puts in everything

The exam loves the pairs inside these groups: peanuts are legumes, not tree nuts; shellfish and fish are different allergens; sesame is separate from the other seeds. Answer options will swap one member of a pair for the other.

Cross-contact: the word the exam is really testing

Cross-contamination moves pathogens — you fight it with temperature, time, and sanitizing. Cross-contact moves allergen proteins — and none of those three weapons work. What works is separation and replacement:

Fresh gloves and clean utensils. Wiping gloves is not cleaning them. A shared spatula carries milk protein even after a wipe.
Wash, rinse, sanitize prep surfaces and cookware. Sanitizer alone does not remove protein residue.
Dedicated fryer oil and clean griddles. Frying wheat-battered food in the same oil as "allergen-free" food is classic cross-contact.
Read the label. Product reformulations move allergens in and out; "it was fine last month" is not an answer.

A typical exam scenario: a guest with a tree-nut allergy orders a dish that normally contains no nuts, prepped next to a pesto station. The correct answer is almost never "cook it longer" or "sanitize the board" — it is clean equipment, fresh gloves, and the wash-rinse-sanitize sequence.

Service answers that repeat every year

Never guess. When a server is unsure whether a dish contains an allergen, the answer is to tell the guest and check with the kitchen, never to reassure.
Take the request seriously. Staff who treat allergy requests as preferences are the scenario the exam describes on purpose.
Deliver allergen orders separately. Handing the allergen-free plate across a nut-covered one undoes the whole kitchen's work.

Try one at exam difficulty

A guest with a milk allergy orders a chicken dish. The prep table was just used for a cream sauce and was wiped with a sanitizer wipe. What should you do?

Prep the chicken — the sanitizer wipe handled it
Cook the chicken to 165°F and serve
Wash, rinse, and sanitize the table, then prep with clean utensils and fresh gloves — correct
Wipe the table a second time with a clean cloth

Wash, rinse, and sanitize the table, then prep with clean utensils and fresh gloves. Sanitizer kills microbes but does not remove milk protein, and cooking temperature destroys bacteria, not allergens. Both wrong options sound responsible — that is exactly how the real exam words allergen traps. ServSafe Domain: Contamination, Allergens & Pest Management

Questions people ask

Is sesame still new enough to show up on my exam?

Yes. Sesame became the ninth federal major allergen in January 2023, and current ServSafe materials include it. If you are studying from older notes or a pre-2023 PDF, your list is short by one — and one wrong answer.

Are sulfites or gluten on the Big 9 list?

Sulfites are a labeling concern but not one of the Big 9. Gluten is connected to wheat but is not listed as a separate allergen — the exam lists wheat. Celiac disease and gluten-free service still matter in the kitchen, just not as a ninth-and-tenth allergen answer.

Do food handler and manager exams test allergens the same way?

Both cover allergen awareness, but the Manager exam goes deeper: cross-contact procedures, label reading, and how to brief servers. Manager questions ask you to choose the correct procedure; food handler questions mostly ask you to recognize the hazard.
