[Two new cases of allergy to tartrazine (author's transl)].

Two patients developed allergy to tartrazine, and the symptoms, as in most such cases, were related to the skin and mucous membranes. The clinical diagnosis was confirmed by the basophil degranulation test. These observations underline the intrication of food substances and medications in the genesis of these accidents and demonstrate the notion of a quantitative contribution of food additives. The author discusses the frequency of these allergies to this colouring substance, and restates the position, which has just been taken by the Academy of Medicine, with the objective of prohibiting the use of tartrazine E 102 in food substances.
