Abstract
Immunological reactions to different food components and the relationship between respiratory dysfunction and immunological status were studied in workers exposed to animal food dust. Animal feed for pigs and chickens was prepared with different components including soy, sunflower seeds, fish flour, corn, different wheats, four leaf clover, carotene, vitamins (A, D, K, B12, C), iodized salt, and minerals (iron, copper, selenium, and calcium). Thirty five workers were evaluated through skin prick and Paper radioimmunosorbent tests, respiratory symptom questionnaires, and ventilatory capacity studies. The exposed workers showed a significantly higher prevalence of chronic respiratory symptoms. No differences were found in this prevalence between animal feed workers with positive and negative skin tests to house dust or to fish flour or among those with increased or normal immunoglobulin-E, except for dyspnea. The frequency of acute symptoms associated with the work shift was high; significant mean across shift reductions in ventilatory capacity were noted, particularly for workers with positive skin tests to fish flour antigen. The authors conclude that animal food dust probably causes direct irritant airway reactions as was indicated by in-vitro testing.
