Understanding Shellfish Allergy and How a Medical Awareness Card Can Help

Shellfish allergy is one of the most common food allergies in the UK. It can cause severe, sometimes life-threatening reactions, even when only small amounts are consumed. Shellfish includes both crustaceans, like prawns and crabs, and molluscs, like mussels and squid. Reactions can happen quickly, often within minutes of eating shellfish or coming into contact with it.

For people living with a shellfish allergy, eating out, travelling, and attending social events can all come with added stress. Restaurants may serve shellfish without clear labelling. Food may be cooked in shared oil. Sometimes cross-contamination is unavoidable. That’s where clear communication becomes essential.

Carrying our Shellfish Allergy Medical Awareness Card is a simple, clear way to inform others about your allergy. Whether you’re speaking to restaurant staff, carers, or fellow travellers, our card can help reduce risk and provide reassurance.

What Is a Shellfish Allergy and Why Does It Happen?

Shellfish allergies are caused by the immune system reacting to proteins found in shellfish. The body mistakes these proteins for harmful substances and triggers a defence response. This response can range from mild to severe.

There are two main types of shellfish:

• Crustaceans: prawns, crabs, lobsters

• Molluscs: mussels, scallops, squid, octopus

Some people are allergic to both types. Others may react only to crustaceans or only to molluscs. It’s important to know your specific triggers and avoid all related foods unless advised otherwise by an allergy specialist.

Common symptoms include:

• Hives or skin rash

• Swelling of the lips, face, or throat

• Wheezing or shortness of breath

• Nausea, vomiting, or diarrhoea

• Anaphylaxis in severe cases

For people at risk of anaphylaxis, carrying adrenaline (such as an EpiPen) is vital. But so is having a quick way to explain your allergy if you're in a stressful or noisy situation. That’s one reason why our Shellfish Allergy Medical Awareness Card is helpful—it speaks for you when you need it to.

The Risks of Accidental Exposure to Shellfish

Shellfish is a common ingredient in many types of cuisine, from Chinese takeaways and sushi bars to paella and fish stews. Even if you don’t order shellfish directly, traces can remain in frying oil, sauces, or on cooking surfaces.

Accidental exposure can happen in:

• Restaurants and cafés

• School and work canteens

• Takeaway shops

• Shared kitchens at events

• Airplane or train meals

It’s not always easy to explain your allergy to staff in busy or noisy environments. Sometimes there are language barriers, or you may be dealing with new people every time you eat out. Carrying our card makes things easier. It provides a clear, visual reminder that shellfish must be avoided. That’s especially helpful when you're speaking to someone unfamiliar with food allergies or when you're in a rush.

How Our Shellfish Allergy Medical Awareness Card Supports You in Daily Life

Our Shellfish Allergy Medical Awareness Card is designed to be practical and easy to use. It’s made from biodegradable plastic, the same size as a standard credit card. That means it fits easily in a wallet or purse and can be carried every day without taking up space.

Because our card isn’t personalised, it’s ready to use straight away. There’s no need to provide a photo or wait for custom printing. The clear wording—“I’m allergic to SHELLFISH”—stands out immediately. It helps others understand what you need at a glance.

You can use our card:

• When ordering food at restaurants

• At buffets or catered events

• While travelling abroad

• In schools or nurseries

• During hospital stays

• At work or in shared kitchens

Many customers keep one card with their travel documents, one in their wallet, and a spare in their car or bag. It’s a low-cost way to add a layer of protection and reduce anxiety when managing a food allergy.

Shellfish Allergy and the Importance of Being Prepared

Living with a shellfish allergy means being prepared in different situations. Even if you’ve never had a severe reaction, allergies can worsen over time. One mild exposure might be followed by something more serious later.

That’s why it helps to stay consistent with precautions. Carrying medication, reading food labels, asking questions when dining out—all of these are part of staying safe. But communication can break down. You might forget to mention your allergy. You might not speak the local language. You might be too unwell to speak clearly. Our Shellfish Allergy Medical Awareness Card adds a backup.

It can also help others support you. Friends, teachers, travel companions, and colleagues may not know the right questions to ask about allergies. Showing them our card helps start the conversation. It’s especially helpful for teenagers or young adults who are still getting used to managing their allergy independently.
