Poultry dust and dander
Chickens are only likely to be a problem when kept inside in commercial confinement buildings.
In broiler operations, respirable particle counts, total dust and endotoxin concentrations, and ammonia levels increase with the age of the flock. In one study levels of total dust averaged 5.0 mg/m3 and Ammonia levels averaged about 13 ppm with peak values of about 50 ppm.
Skin prick tests and Specific IgE are likely to be useful indicators of allergy and exposure.
Extrinsic allergic alveolitis is also a problem in poultry confinement buildings.
Oasys Notifications for Chickens
The Oasys Audit scheme started midway through 2010 and collects agents typed in through the Oasys program. The years before 2010 show old data entered during 2010 or later and are likely to have many fewer notifications. We expect Oasys to become more widely adopted as time goes by so increasing notifications does not necessarily mean an increasing problem.
