Atopic and non-atopic sensitivity in a large bakery

Flour is an allergen which can sensitize either by the digestive or the inhalatory route, particularly those who work with this product. Factors involved occupational four-induced asthma also include various insects and their excreta, fungi and dermato-farinae. In this study, 1303 subjects from a number of bakeries were studied. They underwent allergological investigation by means of prick-tests with allergens and respiratory function tests for those with bronchial asthma. Also studied is the relationship with atopic syndromes or atopic family history.
