Food allergies
A food allergy is based on an immune reaction by the body to harmless vegetable or animal proteins (allergens). In Switzerland, 14 ingredients that may cause an allergy or other adverse reactions must be clearly labelled and highlighted on the packaging.
Food allergy
Tiny amounts of the food in question are often enough to trigger an allergic reaction.
Cross-reactions
It is often the case that someone who has an allergic reaction to tree pollen or house dust mites, for example, is also unable to tolerate certain foods due to a cross-reaction. In rare cases, such a cross-reaction may also occur with allergies to animals and latex.
