Mollusk allergy covers reactions to creatures such as mussels, clams, oysters, squid, and octopus. Although less well-known than crustacean allergy, it can be equally severe. A mollusk allergy card ensures food providers understand exactly which shellfish types you need to avoid.

Where Mollusks Hide in Food

Oyster sauce is a staple in Chinese and Thai cooking and may not always be obvious on a menu. Squid ink is used in pasta and risotto. Scallop extracts can appear in soups and stocks. Cross-contamination is common at fish counters, seafood buffets, and paella-style dishes where multiple shellfish types are cooked together.

How a Mollusk Allergy Card Protects You

Many people - including restaurant staff - are unaware that mollusks are a separate allergen from crustaceans. A clear allergy card specifying the mollusk types you react to prevents confusion and ensures the kitchen checks the right ingredients.

When to Carry Your Mollusk Allergy Card

Use your card at seafood restaurants, Asian restaurants that use oyster sauce, and anywhere serving tapas or mezze with seafood. Travelling in Mediterranean and East Asian countries where mollusks are widely used makes a translated card especially valuable.

Frequently Asked Questions

What is the difference between mollusk and shellfish allergy?
Shellfish is a broad term covering both crustaceans (prawns, crab) and mollusks (mussels, clams, squid). You can be allergic to one group without reacting to the other.
Is squid a mollusk?
Yes. Squid (calamari) and octopus are both cephalopod mollusks. If you have a mollusk allergy, include them on your card.
Does oyster sauce contain real oyster?
Yes. Traditional oyster sauce is made from oyster extract. If you have a mollusk allergy, you need to avoid it. Your allergy card helps kitchen staff identify this.
