Mollusk Allergy

Immunological reaction to mollusk proteins that can cause diverse symptoms.

Definition

Immunological response to proteins present in mollusks (oysters, mussels, squids, etc.). This allergy can cause symptoms ranging from mild to severe.

How it works

Mollusk allergy is a reaction of the immune system that mistakes mollusk proteins for dangerous substances. The body then produces antibodies (IgE) that trigger the release of histamine and other chemical mediators. This allergy is particularly common in coastal regions where seafood consumption is high. Symptoms can appear within minutes to hours after consumption. It can coexist with other allergies to seafood.

Role

No beneficial nutritional role for allergic individuals, who must avoid these foods entirely.

Examples

  • Oysters
  • Mussels
  • Squids
  • Octopuses
  • Escargots
  • Clams
  • Mussels

Recommendations

Carefully read labels of processed products, which may contain mollusk traces. Inform restaurants of your allergy before ordering. Maintain alternative protein sources (fish, poultry, legumes).

Key takeaway

Individuals allergic to mollusks must avoid them entirely and remain vigilant towards cross-contaminations.
