As one of the most popular beverages in the world, tea is highly susceptible to mold contamination during its planting, processing, and distribution. Toxigenic fungi produce mycotoxins under suitable conditions, and humans drinking tea may be at risk of ingesting mycotoxins. In this review, we briefly describe the sources, types, and hazards of mycotoxins in tea, summarize the current status of mycotoxin contamination in tea, discuss the advantages and disadvantages of mycotoxin detection technologies, and outline the prevention and control measures for mycotoxins in tea. This article is expected to provide a reference for the quality control of tea.
