Can shellfish allergy sufferers eat squid?
Quick Answer
Yes
Squid is not classified as shellfish, but as a cephalopod. Therefore, people with shellfish allergies, which are typically allergies to crustaceans and mollusks, can usually eat squid. However, it’s always best to consult with a healthcare provider before trying new foods if you have a known food allergy.

What Is It?
Squid is a type of cephalopod, a group of marine animals that also includes octopus and cuttlefish. It is not considered a shellfish, which typically refers to crustaceans (like shrimp, crabs, and lobsters) and mollusks (like clams, mussels, and oysters).
Why It Can Be Risky
While squid is not a shellfish, it’s important to note that cross-contamination can occur during food preparation, especially in restaurants or places where shellfish are also prepared. This could potentially trigger an allergic reaction.
- Cross-contamination: Squid can be contaminated with shellfish during preparation or cooking.
- Mislabeling: Sometimes, seafood products can be mislabeled, which could lead to accidental consumption of shellfish.
Safe Method?
If you have a shellfish allergy and want to eat squid, make sure it is prepared in a place where no shellfish are handled. Also, always check labels when buying seafood products to ensure they do not contain any shellfish.
Safe Alternatives
If you’re unsure about eating squid, other non-shellfish seafood options include finfish like salmon, tuna, or cod.
