ABSTRACT

Occupational allergy is an important health problem for those exposed to animals, insects, and shellfish in their place of work. The major source of allergens is the excreta and secreta of the animals and insects, which may be airborne and are inhaled by those working with them. The most usual manifestations of allergy are rhinitis, conjunctivitis, contact urticaria, and asthma; asthma is less common but more important, as those with severe symptoms may be unable to continue in their work. Many exhibiting such allergy, particularly those with asthma, have specific immunoglobulin E (IgE) antibody to the responsible proteins. The presence of specific IgE, identified by skin or serological testing, is helpful in diagnosis. The specificity of the immunological response has been exploited to identify the allergenic proteins in different potential sources and to measure the concentration of airborne allergens in the workplace.
