Travelling with a coconut allergy: flights, hotels, sunscreen and saying it in another language

At home you have read everything once. The shampoo, the hand soap, the brand of crackers. Travel takes that away in an afternoon: a bathroom full of unlabelled miniatures, a kitchen you can't see into, and a menu you may not be able to read.

Most of the answer is deciding what to carry so you don't have to find out.

Before you go

Declare the allergy to your travel insurer. Anaphylaxis UK is plain about why: failing to declare it can mean a claim is rejected [1].

Europeans: the health card is not insurance. The EHIC, and the UK's GHIC, give access to state healthcare on a temporary stay. Both official sources say the same thing: it is not a replacement for travel insurance [2, 3].

Take your action plan, in a language they can read. FARE publishes its emergency care plan in Spanish as well as English.

Know the number. It is 112 everywhere in the European Union, free of charge [4]. In Panama it is 911, free from any mobile or landline [5]. Look up anywhere else before you land, not during.

The flight

Adrenaline stays with you. FARE's advice is to keep it on you, not in checked luggage and not in the overhead bin [6]. Security rules allow for it:

• United States. The TSA allows medically necessary liquids in reasonable quantities for your trip; you declare them at screening [7].
• European Union. The volume restriction on liquids does not apply to medicines [8].
• United Kingdom. For liquid medicine over 100 ml you need proof that it is prescribed to you, such as a doctor's letter or a copy of the prescription [9].

Carry a note from your doctor confirming the allergy and the medication either way [6], and check with your airline: some ask for a travel certificate [1].

Bring your own food. FARE's advice is to bring food from home or buy packaged food in the airport, where you can read the label [6]. Airlines say the same thing from the other side. Copa Airlines states it cannot guarantee an allergen-free environment during the flight [10], and Delta says it cannot guarantee an allergen-free flight or stop other passengers bringing products on board [11]. We could not find any special-meal code for coconut.

Wipe down your seat. Tray table, armrests, belt buckle [6]. A review commissioned by the UK's aviation regulator found no evidence that nut allergens travel through cabin air in any meaningful way, and concluded that wiping down the seat area is the most effective thing a passenger can do [12]. That research is about peanuts and tree nuts; there is nothing specific to coconut.

The hotel bathroom

This is the part people don't plan for. Hotel soap, shampoo and lotion often carry no ingredient list on the container, whether it is a miniature or a dispenser on the wall.

The law allows it. In the EU, when a product is too small to label, the ingredient list may go on a leaflet, tag or card instead, or for soap and other small items, on a notice near where the product is displayed [13]. In the US, the labelling rule doesn't cover samples given away free or products used at professional establishments, unless they are also sold in shops [14]. Hotel amenities aren't named in that rule; reading them into it is our interpretation.

Either way, the result is the same: the list exists somewhere, and it isn't in your room. Bring your own. It is the one part of a trip you can settle before leaving the house.

Getting your own products through security

• Liquids in hand luggage are limited to containers of 100 ml (3.4 oz) or less in the US and the EU [8, 15]. In the UK the limit now varies by airport, with some allowing up to two litres [16]. Check both ends of the journey.
• Solid bars are not liquids. The TSA lists bar soap as allowed in carry-on with no size limit [17]. A solid shampoo or soap you have already read is the simplest thing to travel with.

Sunscreen

Sunscreen is the product people most often buy on arrival, in a hurry, in a place where reading the label is hardest.

Three ingredients common in sunscreen are made from coconut: caprylic/capric triglyceride, coco-caprylate/caprate and cocoglycerides [18, 19, 20]. Another, C12-15 alkyl benzoate, is built on fatty alcohols whose source isn't stated and which are often synthetic [21]. The usual "coconut or palm" names turn up too.

In the United States a sunscreen is regulated as an over-the-counter drug, so it carries a Drug Facts panel with the inactive ingredients listed [22]. That is where to look, not the front.

Buy it at home, where you can take your time, and pack enough. Mind the 100 ml limit if you aren't checking a bag.

Eating

Whole cuisines cook in coconut milk as a matter of course, and several of them are places people go on holiday: Thailand, Sri Lanka, southern India, Indonesia, the Philippines, the Caribbean coast of Latin America, the Pacific islands. Eating out lists the dishes and the three questions to ask.

Get a card in the local language. Explaining an unusual allergy across a language gap is where things go wrong.

• FARE's chef cards are free, come in ten languages including Spanish, and are a PDF you type your own allergens into, so coconut can go on it [23].
• Allergy UK's translation cards are paid and made to order; coconut is one of the allergens you can choose [24].

Hand the card over instead of reciting it. It can go to the kitchen; you can't.
