“It is only a little allergy.” The sentence may arrive with a smile, between a request for rosé and a discussion about lunch. Your answer can stay warm while your process stays careful.
You are not there to challenge a guest's experience or diagnose a condition. You are there to understand the requirement, explain what the galley can safely provide and deliver the agreed meal without guesswork. Excellent hospitality makes that conversation feel normal.
Begin with curiosity, not a severity contest
Ask which ingredient must be avoided, what the guest has been advised to avoid, and whether there is an existing allergy-management or emergency plan the relevant crew should know about. Speak directly to the guest, or the responsible parent or carer, when possible. Do not let “no nuts” become three slightly different messages as it travels through the crew.
EFSA explains that a small quantity of an allergenic ingredient can trigger a reaction. A guest's relaxed manner is therefore no reason to reduce kitchen controls. Equally, you should not decide that a person is exaggerating because their requirements look unfamiliar.
A useful response is: “Thanks for telling me. Let us check the ingredients and preparation together so I can explain the options clearly.”
Be reassuring about your process. Be precise about its limits.
Give the information one reliable home
Use a current written record connected to the guest, meal and responsible person. Include the ingredient to avoid, agreed dish, checked components and any unresolved question. Give access to the crew who need it for service and safety; an allergy note is not group-chat entertainment.
The FSA's allergen guidance, applicable to England, Northern Ireland and Wales, recommends written information supported by conversation for non-prepacked food. Its ingredient-recording advice also stresses keeping records current when recipes change.
Your yacht may operate under different rules. Confirm the applicable requirements with management; use this workflow as a practical aid, not a declaration of legal compliance everywhere.

Check the product that actually arrived
The familiar brand, the trusted supplier and last week's recipe are starting points. Read the current package and supplier information, including compound ingredients, sauces, stocks and decorations. An unannounced substitution can change the dish before you have even opened a pan.
The FSA's staff checklist specifically includes approving and recording substitutions, checking deliveries and communicating changes. Assign someone to update the kitchen and service record together.
Keep the label or traceable specification available when decanting. If the language or ingredient is unclear, obtain reliable clarification from the supplier. An automatic translation or AI recipe scan can highlight questions; it cannot verify an unseen manufacturing process or certify that a meal is safe.
Different countries, different label systems
The FDA describes nine major food allergens under US law; EU rules address 14 listed allergen groups, as explained by EFSA. Neither list is an inventory of everything a guest could react to. Read for the person's specific requirement, rather than looking only for bold type or a familiar icon.
Treat precautionary wording such as “may contain” as information requiring an appropriate decision. Its absence is not a complete assessment of the preparation you are about to perform.
Design the meal around a controlled route
Plan ingredients, workspace, utensils, cooking equipment, storage and service before starting. The FDA uses “cross-contact” for an allergen unintentionally entering another food. A clean-looking surface, shared toaster or reused frying oil deserves attention even when the recipe itself contains none of the ingredient being avoided.
Follow your established allergen-cleaning method and use suitable clean or dedicated equipment. Wash hands between tasks. Protect and identify the finished meal so that a helpful last-minute garnish does not undo the work. FSA guidance explicitly addresses separated storage, cleaned utensils and shared-oil risks.
Do not pick nuts off a finished salad and call it suitable. Prepare a fresh meal using verified ingredients and controlled handling. Heating a questionable dish is not your allergen-removal procedure: the FSA's catering control checklist distinguishes heat killing bacteria from residues transferring between dishes. If you cannot control the risk, say so and arrange an alternative you can assess properly.

A small service rehearsal
Imagine a guest avoiding sesame. The salad sounds straightforward, but the dressing contains tahini and the bread delivery has changed. Stop the original dish. Verify a replacement dressing and the bread's actual ingredients and warnings; check the preparation route before agreeing an alternative.
Write the agreed plate into the service note. At the pass, identify the guest and dish using the crew's agreed method. The server confirms the requirement again, without making an unsupported “completely safe” promise. These final seconds deserve the same attention as the plating tweezers.
Make the emergency plan familiar before dinner
Ensure the captain and designated trained crew know the response arrangements, access to urgent medical help and relevant guest emergency information. Know where the guest's prescribed medication is kept and who can assist according to training and the person's plan.
NHS guidance describes anaphylaxis as a rapidly developing, life-threatening emergency. Suspected anaphylaxis needs immediate emergency help and use of an available adrenaline auto-injector according to its instructions and the person's plan. The NHS's emergency number is 999 in the UK; use the appropriate local or maritime emergency route for your location. Do not wait for every symptom or for a rash before raising the alarm.
This article does not replace medical training or a vessel emergency procedure. Review the plan before departure, not while someone searches a drawer.
The pre-service check
Confirm the guest's requirement, verify today's ingredients, control preparation, identify the correct plate and brief the server. Keep a workable alternative ready. The aim is a guest who feels listened to and a crew who know exactly what happens next. That is a particularly good form of luxury.
