Abstract：Dry aging is a method for preserving unpackaged carcasses or cuts under controlled conditions of temperature, relative humidity, and airflow for several weeks. This process improves the tenderness, flavor, and juiciness of beef. However, given the direct exposure of beef to the production environment and the long aging process, the microbial status of dry-aged beef requires special attention. This review summarizes the microbial load and prevalent microorganisms in dry-aged beef, and discusses the primary factors that influence the microbial status. Additionally, this paper illustrates the contribution of beneficial microorganisms to the development of the characteristic quality attributes of dry-aged beef. It also provides an overview of potential pathogenic and spoilage microorganisms in dry-aged beef, along with strategies for their control. The objective of this review is to provide valuable insights for optimizing microbial resource management and enhancing microbial safety in the production of dry-aged beef.
