Organic contamination of crops poses a threat to the safety of food products and human health, and it is urgently needed to be solved. Endophytic bacteria are indispensable in microecosystems. In recent years, researchers have screened and isolated endophytic bacteria with the function of degrading pollutants from the environment. These bacteria have been used to regulate the metabolic processes of organic pollutants in crops, which achieve the efficient reducing of toxic organic pollutants in crops. This paper reviews the research progress in the reduction of toxic organic pollutant accumulation in crops by functional endophytic bacteria, focusing on the degradation genes, products, and pathways of toxic organic pollutants in crops after the colonization of functional endophytic bacteria. Furthermore, it discusses the factors affecting the degradation efficiency of functional endophytic bacteria and emphasizes the importance of these bacteria in reducing organic pollutants in crops. This review provides ideas and a basis for the further utilization of endophytic bacteria to control the risk of organic contamination in crops.
