▶What are the major food allergens and which ones are most common?
The FDA recognizes nine major allergens: peanuts, tree nuts (almonds, cashews, walnuts), milk, eggs, fish, shellfish (shrimp, crab, lobster), soy, wheat, and sesame. Peanuts and tree nuts are the most severe (can cause anaphylaxis, a life-threatening reaction). Shellfish and fish are common in coastal areas. Milk and eggs are common in baking and sauces. Soy and wheat are common in Asian foods and bread. Sesame is increasingly common as it is used in tahini, hummus, and Asian cuisines. Always ask customers about allergies, and never assume an ingredient is safe. Some people are allergic to specific nuts but not others (e.g., allergic to peanuts but not tree nuts), so ask for clarity.
▶What is cross-contact and how do I prevent it?
Cross-contact is the unintentional transfer of an allergen from one food to another, typically through shared utensils, cutting boards, or preparation surfaces. A peanut protein particle too small to see can trigger anaphylaxis. Prevent cross-contact by: (1) Using separate cutting boards, knives, and utensils for allergen-free prep. (2) Washing hands thoroughly between handling allergen and non-allergen foods. (3) Cleaning preparation surfaces with hot soapy water and a clean cloth between tasks. (4) Using separate fryers and grills for allergen-free foods if possible. (5) Never reusing contaminated oil, water, or sauces. Cross-contact is a serious legal liability: if a customer has an allergic reaction due to cross-contact, you can face a lawsuit.
▶How do I label dishes for allergens and communicate with customers?
List all allergens on the menu: either next to each dish or in a legend (e.g., (M) = contains milk, (N) = contains nuts). Train staff to always ask customers about allergies when taking orders. When a customer reports an allergy, repeat it back to confirm you understand (e.g., 'You are allergic to shellfish, correct?'). Inform the kitchen immediately, using a different ticket or label (e.g., a red ticket or verbal call-out: 'Scallops, no shellfish cross-contact'). Prepare the allergen-free dish on a completely separate station. Verify the dish is prepared correctly before serving. Give clear verbal confirmation to the customer: 'This dish contains no shellfish and was prepared in a shellfish-free area.' Never guess or assume; always verify with the customer and the kitchen.
▶How do I manage dietary restrictions beyond allergies?
Dietary restrictions include: vegetarian (no meat, poultry, or fish), vegan (no animal products), gluten-free (no wheat, barley, rye, oats if not certified), kosher (Jewish dietary laws), halal (Islamic dietary laws), and religious (Hinduism avoids beef, some Buddhists avoid meat). Ask customers to specify their restriction and ask clarifying questions (e.g., 'Is it an allergy or a preference? Can you eat fish? Dairy?'). Design your menu to accommodate common restrictions: at least one vegetarian main, vegan options, gluten-free bread or substitutes. Train staff on your restaurant's ability to accommodate restrictions: do not promise something you cannot deliver. Label menu items clearly. Many customers have multiple restrictions (e.g., vegetarian and gluten-free), so ask what they need.
▶What is the legal responsibility for allergen disclosure?
In most jurisdictions, restaurants are legally required to disclose allergens when asked. In the European Union, all main allergens must be listed on the menu or available upon request. In the U.S., the Food Allergen Labeling and Consumer Protection Act (FALCPA) requires labels on packaged foods, but the law is less clear for restaurants. However, many states and local jurisdictions have allergen disclosure laws. Failure to disclose an allergen can result in a lawsuit if a customer has an allergic reaction. Always err on the side of transparency: list all allergens, ask about allergies, and prepare allergen-free meals separately. If you are unsure whether an ingredient contains an allergen, find out from the supplier before serving it.
▶How do I create a vegetarian or vegan menu and ensure it is not a second-class option?
Many restaurants treat vegetarian dishes as an afterthought, offering boring salads and pasta. Instead, design vegetarian and vegan dishes with the same care and attention as meat dishes. Use interesting proteins (legumes, tofu, tempeh, mushrooms, nuts), build flavor through sauces and seasonings, and plate them beautifully. A vegetarian main should be as satisfying and restaurant-quality as the meat main. Train your kitchen to treat vegetarian dishes with the same respect: they should be cooked with the same precision and attention. Many vegetarians are tired of being treated as an inconvenience; make them feel valued by offering excellent options. A well-executed vegetarian menu attracts both vegetarians and flexitarians (people who eat mostly plant-based but are open to meat occasionally).
