This Topic Page is mostly about bivalve purification training and includes information on other shellfish issues such as scallop shucking.


Bivalve shellfish such as mussels and oysters are required to be purified before they are sold unless they are harvested from Class A Waters. Seafish and the Seafood Training Academy provide information and training to employers and employees involved in the harvesting, purification, handling and trading of bivalve shellfish.
