Occupational skin diseases in tanneryworkers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined in those studies. Objectives. To assess the prevalence of occupational allergic contact dermatitis in Indonesian tanneries, identify the causative allergens, and propose a tannerywork series of patch test allergens. Patients/methods. A cross-sectional study in all workers at two Indonesian tanneries was performed to assess the prevalence of occupational contact dermatitis via a questionnaire-based interviewand skin examination.Workerswithoccupational contact dermatitis were patch tested to identify the causative allergens. Results. Occupationalcontactdermatitiswassuspected in77(16%)of the472workers. Thirteen (3%) of these 472workerswere confirmed to have occupational allergic contact dermatitis.
