Question: if allergic to shellfish can you have oyster sauce?
Answer: It depends on what type of “shellfish” allergy you have. There are multiple kinds of shellfish: crustaceans, such as lobster, shrimp, and crab, bivalves, such as clams and oysters, and molluscs, such as snails, octopus, and squid. ... While I do not like bivalves, I can and do eat things like oyster sauce.
