What type of shellstock includes clams, oysters, or mussels in their raw, in-shell state?

The term "shellstock" specifically refers to shellfish that are harvested and sold in their raw, in-shell state, including clams, oysters, and mussels. This classification is essential within food safety and handling regulations because shellstock must be stored and managed properly to prevent contamination. It is intended for use by consumers in a raw or minimally cooked manner.

In contrast, frozen food refers to seafood or other products that have been preserved by freezing, which alters the state and could diminish the characteristics associated with shellstock. Prepared seafood means that the products have been cooked, seasoned, or otherwise modified for consumption, while processed shellfish may have undergone various treatments, including cooking, pasteurization, or packaging methods that change their original raw state. Hence, shellstock is the correct classification for clams, oysters, and mussels in their raw form.
