Seafood Restaurants

Because the main food served at a seafood restaurant is obviously seafood, it is best to steer clear of seafood restaurants. I used to be allergic to shellfish, and my family stayed away from seafood restaurants because of the high risk of cross contamination.

Mollusks vs Crustacea

Shellfish is generally categorized into two groups: mollusks and crustacea. When diagnosed with a shellfish allergy, it is possible to avoid one group and still eat foods from the other group.

Examples of mollusks include:

clams

mussels

octopus

sea urchin

scallops

 

 

Examples of crustacea include:

crab

krill

lobster

shrimp
