Is it ok for shellfish allergy sufferers to eat octopus?
Quick Answer
Yes
Octopus is not considered shellfish and is generally safe for people with shellfish allergies to consume. However, cross-contamination can occur during food preparation, so it’s important to ensure the octopus has not come into contact with shellfish.

What Is It?
Octopus is a type of cephalopod, a group of mollusks that also includes squid and cuttlefish. Unlike shellfish, such as shrimp, crab, and lobster, cephalopods do not have a hard outer shell.
Why It Can Be Risky
While octopus is generally safe for people with shellfish allergies, there are still potential risks to consider.
- Cross-contamination: Octopus can come into contact with shellfish during food preparation, which can trigger an allergic reaction.
- Mislabeling: Sometimes, seafood products can be mislabeled, which can lead to accidental consumption of shellfish.
Safe Method?
To safely consume octopus, ensure it is prepared in a shellfish-free environment and verify the accuracy of food labels.
