Shellfish Allergy

Immune reaction to proteins from shellfish.

Definition

An undesirable immune reaction caused by the proteins present in shellfish, such as shrimp, lobsters, and crabs.

How it works

A shellfish allergy is one of the most common food allergies, particularly in coastal regions. It's caused by an immune system reaction to tropomyosines and other proteins found in these marine animals.

Role

Shellfish provide protein, minerals, and omega-3 fatty acids, but cause an immune reaction in allergic individuals.

Examples

  • Shrimp
  • Lobsters
  • Crabs
  • Langoustines
  • Crawfish
  • Peeled shrimp

Recommendations

Carefully read product labels and inform restaurants of this allergy. Wear an EpiPen if prescribed by a doctor, and consult an allergist to confirm the diagnosis.

Key takeaway

A shellfish allergy requires constant vigilance and complete avoidance of these foods.
