Seafood allergy and shellfish on island menus
Your child has a seafood allergy and you want to know what to ask a coastal kitchen.
On an island, seafood is part of nearly every kitchen, so a seafood or shellfish allergy needs more than a polite note at booking. Ask what the kitchen does to keep your child’s food apart from seafood, and ask for the reply in writing. Talk to your child’s doctor about what to carry and what to do in an emergency. We are not medical advisers, so treat this page as a list of questions.
For wider context, read halal and dietary needs on island resorts and special diets and medical meals. To check the distance to help, read medical help on islands.
How does seafood reach a plate indirectly?
A dish without seafood on the menu can still touch it. Think about the places where seafood travels in a busy coastal kitchen.
- Frying oil that is shared between fish, prawns and chips.
- Sauces and seasonings such as fish sauce, oyster sauce and shrimp paste.
- Stock and soups made with fish or shellfish bones or shells.
- Grills, woks and chopping boards used for several dishes.
- Serving spoons at a buffet that move between dishes.
The implication: asking whether a dish “has seafood” is not enough. Ask how it is cooked and with what.
Which questions go to the kitchen?
| Area | Question |
|---|---|
| Cooking oil | Is oil shared with seafood dishes? |
| Sauces and stock | Do any of the child’s likely dishes use fish sauce, oyster sauce, shrimp paste or seafood stock? |
| Utensils | Are separate utensils and surfaces available? |
| Buffet | How are serving spoons kept apart? Can a dish be prepared fresh? |
| Staff | Can the kitchen team be told in advance? Who is the contact? |
| Menu | Can you list the dishes that are safe in your kitchen’s view? |
Remember that a resort can only describe its practice. It cannot make a promise about a kitchen that handles seafood every day.
What should your written request say?
Keep the message short and factual:
- Who is travelling, and the age of the child.
- The allergen, named as your doctor has named it.
- A request for the kitchen’s practice on oil, sauces, stock and utensils.
- A request to know who the contact person is.
- A request to hold the reply with the booking.
Do not send medical records. Never make the message longer than it needs to be.
What should you carry, and what if help is far away?
Ask your child’s doctor for a written plan, and carry the medicines they prescribe in your hand luggage, not in a checked bag. Share the plan with every adult in the group.
Then ask the resort how emergencies work on the island: who is trained in first aid, how fast a boat can leave, and where the nearest clinic is.
Our page on meals on arrival day and departure day also helps you plan the travel hours, when children are often hungry and rushed.
What if the answers are not good enough?
You are entitled to decide the resort is not right. Compare another resort, or ask whether a self-catering option helps. Our guide on kitchen access and self-catering explains what that might look like.
A better fit if…
A resort that replies in detail, names its practices and gives a contact may be a better fit if your child has a serious allergy.
A place with limited kitchen detail may suit you only if the allergy is mild and you have your doctor’s plan. You must also be comfortable carrying most of the food you rely on.
Decide with your doctor’s advice and the resort’s written reply together.
Common questions
Can an island resort guarantee a seafood-free meal?
Do not expect a guarantee. A kitchen can describe its practice, but cross-contact is hard to rule out in a busy kitchen that cooks a lot of seafood. Ask what it does, ask for it in writing, and decide whether that is enough for your child.
What hidden sources of seafood should I ask about?
Ask about shared frying oil, fish sauce, oyster sauce, shrimp paste, stock, sambal, and shared grills and utensils. These can appear in dishes that look free of seafood. Ask the kitchen to list which dishes use them.
What should I carry with me?
Ask your child's doctor what to carry and what to do in an emergency, and follow their plan. Keep any prescribed medicines in hand luggage, with a copy of the plan. Tell your group where they are.
What if help is far away?
Ask the resort how emergencies are handled, who is trained in first aid, and how a boat transfer to a clinic works. Our page on medical help on islands covers the questions. If the answers are weak, consider another place.
