ABSTRACT:
Exposure to microorganisms in farm environments may cause respiratory disorders, e.g. asthma, organic dust toxic syndrome and allergic alveolitis. By reducing microbiological deterioration of organic materials, some agricultural practices have a protective effect. Microbiological analyses were carried out on hay, silage and flour samples (n=107) from farms in Finland and France (n=23) that use different methods of haymaking. High concentrations of Absidia corymbifera were found in approximately 35% of French hay samples and only 10% of Finnish hay samples. Concentrations of Eurotium spp. were found in 20% of hay samples from both regions. High concentrations of Wallemia sebi typified Finnish hay (38%) more than French hay (8%). Rhodotorula yeast was frequently and abundantly found in Finland, but never in France. The method used to make hay appeared to be the main factor affecting the microbiology of the hay. A. corymbifera and Eurotium spp. concentrations were smaller in low-density square bales than in others. In conclusion, our results emphasize the importance of good agricultural practice in the microbiological quality of fodder.
