Evaluation of Bioaerosols Concentrations in Mushroom, Swine and Poultry Farms: Case of Workers in Warinchamrab, Ubon Ratchathani
Main Article Content
Abstract
This study aims to examine airborne fungi and bacteria in mushroom, swine and poultry farms located in Warin Chamrab, Ubon Ratchathani. Air samples were collected with NIOSH method 0800 BIOAEROSOL SAMPLING (indoor air). The results showed that the maximum fungi concentration in mushroom, swine and poultry farms were 2,938.75, 2,575.58, and 2,245.78 CFU/m3, respectively. The maximum bacteria concentrations were 4,570.08, 2,524.54, and 14,813.51 CFU/m3, respectively. The maximum concentrations of bacteria found in mushroom and swine farms were not more than the suggested level from IRSST (Occupational Health and Safety Research Institute Robert Sauvé) which was 10,000 CFU/m3 in the air for 8-hour working day. However, in the poultry farm, the maximum bacteria concentration was above the suggested level and this might affect the workers’ health. In addition, the isolated fungi and bacteria from the air samples were identified. In mushroom farm, there were 4 genera of fungi, namely Aspergillus spp., Aspergillus niger, Penicillium sp. and Rhizopus sp. and 2 genera of bacteria, namely Bacillus sp. and Staphylococcus sp. In the swine farm, there were 4 genera of fungi, namely Aspergillus spp., Curvularia spp., Penicillium sp. and Rhizopus sp. and 2 genera of bacteria namely Bacillus sp. and Staphylococcus sp. In poultry farm, there were 5 genera of fungi, namely Absidia sp., Penicillium sp., Aspergillus niger, Aspergillus spp. and Fusarium sp. and 2 genera of bacteria, namely Bacillus sp. and Staphylococcus sp. These were associated with respiratory diseases and allergies, especially (such as Penicillium sp. and Aspergillus spp.) in people with hypersensitivity or patients. These might cause asthma, cough, and wheezing. Moreover, exposure to airborne fungi and bacteria at high concentrations might result in reducing lung capacity. The results of this study could be used as a guideline to improve the air quality in the farms. Therefore, monitoring the indoor air quality was suggested to control the number of fungi and bacteria in the farmhouses or agricultural sheds. These would be the way to prevent harm and reduce the cause of illness for workers who expose to airborne fungi and bacteria.
