Abstract

This study was undertaken to determine the concentrations of airborne bacteria, fungi, particles, and endotoxin in swine and chicken houses. Six swine buildings and seven chicken houses were randomly selected in southern Gyonggi Province, South Korea. The geometric mean concentrations of airborne bacteria in swine and chicken houses were 2.7×105 CFU/m3 and 5.6×107 CFU/m3, respectively. The airborne bacteria concentrations in chicken houses were significantly higher than those of swine houses (p<0.05). The geometric mean concentration of airborne fungi in swine houses was 4.9×103 CFU/m3, which was higher than the value of 2.1 × 103 CFU/m3 found in chicken houses. The mean concentrations of airborne particles and endotoxin in swine houses were 3.48 mg/m3 and 943.1 EU/m3, and they were 15.43 mg/m 3 and 1,430.5 EU/m3 in chicken houses, respectively. A significant difference between swine and chicken houses was found for total dust (p<0.05), but not for endotoxin. In this study, the concentrations of endotoxin in both swine and chicken houses as well as particles in chicken houses were high, and in about 50% of the samples exceeded the worker health safety levels of 614 EU/m3 suggested in previous studies. These results may indicate a considerable respiratory hazard for workers in these environments.
