Title Occurrence of farmer's lung disease is relevant to meteorological conditions: A 20-year follow-up field survey analysis
Bibliographic information June 2002, Vol.41, No.6, p.506-513. Illus. 20 ref.
Abstract A survey on farmer's lung disease (FLD) in a dairy farming community in the northernmost district of Japan has been in progress since 1978. This article investigates possible correlations between the number of FLD occurrences each year, dairy farming conditions and meteorological data. 34 FLD cases had occurred during the 20-year period. The average number of days below freezing point during the harvest season the year prior to FLD occurrence were significantly smaller than other years (2.1▒0.7 days and 4.6▒0.7 days, respectively). The average annual sunlight hours in the years preceding FLD occurrence was significantly smaller than those of other years (1457.1▒114.0h and 1811.3▒97.7h, respectively) and was also significantly smaller for the sunlight hours during a harvest season (821.9▒ 60.2h and 1023.2▒52.7h, respectively). It is concluded that temperature and hours of sunlight are closely associated with FLD occurrence.
