The oyster is a bivalve mollusk of the genera Ostrea and Crassostrea, consumed fresh, canned, and smoked. It is known that oysters can act as allergens causing allergic reactions upon ingestion and occupational allergies from contact with shell dust. Oyster farming is especially common in Japan and China, where they are a staple ingredient in various culinary products.

Oyster shell dust has been identified as an inhalant allergen in occupational asthma. Cases of anaphylaxis triggered by physical exertion after consuming smoked oysters have been reported. Oyster extracts share antigenic structures with crustaceans, which may cause cross-reactions, particularly with blue mussels.
