What is Shellfish?
Shellfish are a diverse group of aquatic animals that possess a shell, and they are commonly categorized into two groups: crustaceans (such as shrimp, crabs, and lobsters) and mollusks (such as clams, oysters, and mussels). Shellfish are widely enjoyed as a delicacy and are a rich source of protein, omega-3 fatty acids, and various vitamins and minerals. However, they are also one of the top allergens, and consumption can lead to severe allergic reactions in sensitive individuals.
