Descrizione riassuntiva dello studio

This study aims to investigate whether people with a house dust mite allergy may have a greater risk of allergic reactions to insects as food, especially if they are already allergic to seafood. Additionally, we want to examine whether this risk may also be influenced by where one grew up or currently lives. Furthermore, we will investigate what sensitizations to insects are found in employees who regularly come into professional contact with edible insects. In a subgroup of participants, we will also investigate whether they may react allergically to chicken meat.
