Mollusks allergy: where it hides in an ingredients list

Mussels, oysters, squid, scallops, and snails are in the same group. They are usually listed directly in ingredients, but their extracts are not.

Frequently asked questions

Are snails also mollusks?
Yes, land gastropods belong to the same group and are labeled the same way in ingredients.
Does oyster sauce always contain oysters?
Generally, yes—in the form of extract. There are versions without them, and this should be indicated in the ingredients.
How do I check whether a product contains mollusks?
Photograph the barcode or the ingredients panel — the app reads the list and warns you if it finds anything you have flagged. Three checks are free, with no account.
How do I avoid ordering a dish with mollusks in a restaurant?
Photograph the menu — the app reads the items and marks the ones whose name suggests an allergen you flagged. A menu carries no ingredients list, so the check is approximate: hidden ingredients are visible only in the kitchen.

Check the package rather than remember the list. Photograph the barcode and the app reads the ingredients and flags what you marked.
