Sources and Methodology

1. Our primary sources

Food safety questions are written from the FDA Food Code. We use the 2022 edition with its November 2024 supplement, which ServSafe documents as the basis of its current Manager book, and the 2026 edition, which is FDA's most recent. The citation on each question names the edition it quotes.

Allergen questions also draw on FDA and CDC food allergy pages, including FDA's page on allergen removal by wiping and cleaning.

Alcohol questions draw on the National Institute on Alcohol Abuse and Alcoholism (NIAAA), the National Highway Traffic Safety Administration (NHTSA) and the California Department of Alcoholic Beverage Control. Alcohol laws differ by state, so the 48 questions that depend on state law are marked.

Other sources include CDC food safety pages, FDA's Bad Bug Book and the OSHA hazard communication standard.

Facts about exam formats and pass marks come from ServSafe's own public FAQ and product pages.

2. What we do not treat as a source

• Other practice and mock exam websites. We saved questions from some of them for research, and scripts compare our questions against that set to catch overlap. They are not cited as evidence for any fact.
• Forum posts, social media and video comments.

3. How citations are checked

Each of the 1,366 questions has a citation with a verbatim quote from its source, and many have supporting citations, for 1,818 citations in total. A script checks that every quote appears in our saved copy of the source.

Each saved source records the date we fetched it and a hash of its text. Each question record stores the date it was last verified. If the saved source text changes, the reviews that depend on it no longer count and the questions have to be reviewed again.

5. The limits of our methodology

• ServSafe's current detailed blueprints and outcome documents are not publicly crawlable, so we did not read them. We claim no official topic percentages, and we cannot show complete coverage of what the exams test.
• Manager pass mark: ServSafe's current FAQ and online proctoring guidance state 70%, which is 56 of 80 scored questions. An older examinee handbook states 75%. We use 70%. We could not confirm when the change applied.
• Food Handler: ServSafe's course page states 40 questions and a 75% pass mark. Its pages differ on the number of attempts allowed, so we state no universal rule.
• Alcohol: ServSafe's FAQ gives 40 questions and 75% (30 of 40) for the Primary exam. Product pages for newer and state-specific versions differ, so we state no single format for every version.
• Allergens: ServSafe's product page states 40 questions. We found no official pass mark in public sources. The 75% we use is our own practice target. ServSafe's pages also differ on attempts and access period.
• The FDA Food Code is a model code. States and local agencies adopt and amend it differently, so a correct answer here may differ from a rule where you work.
• The 2026 Food Code does not establish that ServSafe courses have adopted every new provision.
• Automated checks confirm citations, review records, counts and overlap. They do not prove that a judgment about a fact is correct, that our coverage is complete, or that our wording is perfectly original.
