Vicia faba Hypersensitivity and ASA Intolerance in a Farmer : A Case Report

Abstract EN

The IgE-mediated allergic reactions to food are caused, generally, by ingestion.

However, they can be rarely induced by exposure to airborne food particles through the handling or the cooking.

Vicia faba is a vegetable which belongs to Legumes or Fabaceae family, Fabales order.

Allergic reactions after ingestion of legumes and cases of asthma after exposure to the cooking vapors have been reported in the literature.

A paper assessed the volatile substances (insect repellents) released by V.

faba.

The authors demonstrated that this plant produces several chemical substances, such as small quantities of methyl salicylate.

We describe a case of occupational allergy, induced by handling during picking up of fresh broad beans, in a farmer with history of adverse reaction after eating the cooked and raw vegetable.
