Allergen pollen in the food of pet animals

Pets kept in flats are known to be major sources of allergens. Clinical observations suggest that pets can cause serious allergic rhinitis, urticaria, Quincke-edema and bronchial asthma even indirectly. Pollenanalytical examinations proved that the commercially available unwashed pet food (seed mixtures) in Hungary contains several seriously allergen pollen and mould spores attached to the seeds. Thus, seeds cleansed unproperly can prove to be serious indirect allergen sources.
