Microbiological risks related to the industrial poultry and animal production

The intensive poultry and animal farming generate substantial amounts of bioaerosols, dust, and harmful gases entering the environment daily, which pollutes the adjacent area with the radius ca. 3 km (M.V. Vlasov et al., 2010). Average dust load in the air of a poultry house can reach 10 mg/m3 (M. Saleh et al., 2014), with median concentration of endotoxins reaching 257.6 ng/m3 (K. Radon et al., 2002). Microbial load in the deposited dust can reach 3.2×109 CFU/m3, fungal load is 1.2×106 CFU/m3 (J. Skora et al., 2016). Concentrations of mesophilic bacteria in the air can reach 8.8×104 CFU/m3 in an animal house (E. Karwowska, 2005) and 1.89×108 CFU/m3 in a poultry house (K. Roque et al., 2016). Microbial population in the air within the premises for cattle growing can include pathogenic strains Staphylococcus aureus, Streptococcus faecalis, Escherichia coli, Candida spp...
