With global population growth and rising consumption,the large-scale expansion of animal husbandry has become an irreversible trend. However, alongside ensuring food supply, the rapid development of livestock and poultry farming has also brought about severe ecological and environmental problems. Notably, the farming system has become both an important source and sink of emerging pollutants. As an emission source, the farming process continuously releases emerging pollutants such as Antibiotics, persistent organic pollutants, endocrine disruptors, microplastics, pesticides. As a sink, these pollutants accumulate in livestock through the food chain, creating a multi-level amplification effect that poses significant threats to ecosystems and human health. This paper reviewed the main types and sources of emerging pollutants in livestock farming, their occurrence characteristics and environmental behaviors, analyzed their potential impacts on the environment and human health. We further discussed the pollutants management idea of reduction at the source,interception during the process, and purification at the end. We also summarized the current research gaps,and outlined future research directions. This paper aims to provide a scientific basis for China's emerging pollutant control system construction and policy optimization,and to promote the sustainable development of the livestock industry.
