• Description:
  An air sampling study was undertaken to study the nature of the exposure that occurs in mechanical bedding chopping. Three common serious aeroallergens were studied: Thermoactinomyces-vulgaris, Micropolyspora-faeni, and Aspergillus-fumigatus. Barn ventilation was under winter conditions. Collection periods were 20 to 60 minutes long. The allergen rise was significant during bedding chopper operations. The rise in colonies of mesophilic fungi was highly significant during the chopper operation. The authors concluded that dairy farmers using bedding choppers were exposed to massive levels of potentially hazardous aeroallergens. The culture studies confirm massive rises in viable mesophilic fungi. The potential for allergic alveolitis and allergic aspergillosis would seem to be greatly increased by the use of this device without proper ventilation and personal protective equipment.
