What is Allergen Protocol?
Also known as: allergen procedure, allergy handling
An allergen protocol is a restaurant's defined procedure for handling guest allergies — how staff identify allergens in dishes, communicate them accurately, prevent cross-contamination, and confirm what's safe. Because a mistake can be life-threatening, allergen knowledge is the highest-stakes part of staff training.
A solid allergen protocol covers the whole chain: the server recognizing an allergy disclosure, knowing (or checking) exactly which dishes contain the allergen, communicating clearly with the kitchen, and the kitchen preventing cross-contamination during prep and plating. Any weak link puts a guest at risk.
The nine major allergens most protocols train on are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. But the risk isn't just the obvious ingredient — it's the hidden one: anchovy in a Caesar dressing, a shared fryer, wheat in soy sauce. That hidden detail is what catches undertrained staff.
This is why ShiftTrained treats allergen questions as first-class. Its pipeline fact-checks every allergen claim against the source menu with a separate AI verification pass, and a manager approves any 'safe for celiac' or 'dairy-free' claim before it reaches staff — so training never teaches a dangerous shortcut.

Frequently Asked Questions
What are the 9 major food allergens?
In the U.S., the nine major allergens are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame (added in 2023). Most restaurant allergen training centers on identifying these in dishes and preventing cross-contamination.
How do restaurants train staff on allergens?
The strongest approach pairs a written protocol with verification: staff learn which dishes contain which allergens, how to prevent cross-contamination, and how to communicate with the kitchen — then get quizzed on it, because allergen mistakes carry real risk and can't rely on memory alone.
