Źródła skażenia powietrza i zagrożenie szkodliwym bioaerozolem w zakładach przetwórstwa rolno-spożywczego
Sources of indoor air contamination and harmful effects of bioaerosol in agri-food processing plants

Summary/Abstract: In this paper we described biological contamination sources of the indoor air in the agri-food industry. Predominantly, microorganisms can spread into the air during the processing (i.e. from the raw material or the equipment), through the ventilation and air conditioning systems, and also from the employees. The composition of bioaerosol and possible health effects of its transfer onto working surfaces of the food processing plant were discussed. Pathogenic bacteria such as Salmonella spp., Escherichia coli, Listeria monocytogenes or staphylococci can be present in the air in addition to saprophytic microorganisms, which are not directly harmful to human health, but can inflict food spoilage. In this paper we highlighted the risks of microbial aerosol and its influence on the health of the employees exposed to it.
