Prevention of occupational disease (farmer's lung): Inoculation of bacteria in fodder Abstract The bacterium Micropolyspora faeni, present in mouldy hay, triggers an allergic reaction known as farmer's lung in some farmers. The growth of Micropolyspora faeni may be prevented by inoculating hay with other bacteria. The purpose of this project was to determine the effect of these bacteria on the microflora of the ambient air. It was also meant to see whether they caused an allergic reaction, and whether farmers have developed antibodies against these bacteria, as well as the effect on their breathing. Using an animal model, the research showed that the inoculation bacteria are just as allergy-causing as those associated with moulding. An analysis of 19 farms using the treatment and 18 others not using it showed that the treatment improves neither the quality of air nor the quality of hay, and does not affect the farmers’ breathing.
