Why should shellfish be stored on the bottom shelf?

• A. To prevent drips from contaminating foods above
• B. To keep shellfish warm
• C. To prevent the shelf from rusting
• D. To make shelves easier to clean

Answer: (D)

Preventing cross-contamination is the key idea here. Raw shellfish can carry bacteria, and its juices can contaminate other foods if they drip onto them. Storing shellfish on the bottom shelf helps contain any leaks and keeps drips from reaching foods placed on higher shelves, especially ready-to-eat items. This practice directly reduces the risk of foodborne illness. It isn’t about keeping shellfish warm, preventing rust, or making shelves easier to clean—the safety concern is preventing juices from contaminating other foods.
