Abstract

Inhalation of airborne microorganisms and organic dust is an occupational concern among workers in agricultural industries. Airborne microorganisms and particulate matter samples were collected from poultry house, flourmill, textile, and food industry sites by use of liquid impinger and gravimetric samplers. Particulate matter concentrations were recorded at median concentrations of 1.56, 1.92, 4.39, and 0.7 mg/m3 in the occupied poultry house, textile, flourmill, and food indoor working environments, respectively. The highest median particulate matter concentration (27.9 mg/m3) was detected at the flourmill's stack site. The highest median indoor concentration of culturable airborne bacteria (6.23 × 10 5 CFU/m3) was found at the occupied poultry-house site and the lowest concentration (4.6 × 103 CFU/m3) was found at the food industry site. The highest median indoor concentration of culturable airborne fungi (3.15 × 104 CFU/m3) was found at the flourmill site whereas the lowest (1.24 × 103 CFU/m3) was found at the textile industry site. Bacillus and Staphylococcus were the predominant Gram-positive bacteria whereas Acinetobacter and Klebsiella were the predominant Gram-negative bacteria. Escherichia coli and Salmonella were only detected in the indoor air at the poultry house site. Aspergillus flavus, Aspergillus niger, Penicillium, and yeast were the predominant fungal types at flourmill, textile, food industry, and poultry house, respectively. Workers were continuously exposed to airborne microorganisms at a median value of 104 CFU/m3 in all the industries studied.
