Abstract: The bioaerosol generated and emitted from intensive livestock breeding operations is a potential gaseous pollutant thatmay bring about harm to health of the animals and workers in the operation and pollution of the surroundings at a far distance.A brief introduction is presented to the status quo of the pollution, characteristics of the productionand particle size distribution of the bioaerosol and their influencing factors;progresses in the study on bioaerosol carrying antibiotics-fast bacteria and genes are summarized; and an outlook is described on foci and direction of the research in future with an expectation of providing some reference for controlling generation and emission of bioaerosol from intensive livestock breeding.
