Abstract
Raisin allergy is uncommon despite worldwide cultivation of grapes, which belong to the Vitis vinifera species of the Vitaceae family. There have only been rare reports of anaphylaxis in adults related to the consumption of grapes, wine or other grape products, mostly in Europe [1-4]. In children, even fewer case reports to grape exist [5]. We report an 8-year-old patient who developed itching of the mouth and nausea within a few minutes of ingestion of fresh raisin on repeated occasions. Interestingly, he tolerates grapes.
