This paper reviews the studies about mycotoxin contamination in tea. Some results showed that mycotoxin producing fungi and mycotoxins were detected in black tea, green tea, white tea and dark tea. It needs to pay attention to the possibility of mycotoxin contamination in tea. To reduce the risk of mycotoxin contamination in tea, it is suggested to monitor mycotoxins in various types of tea, and develop safe fermentation technology of dark tea by process control using non-mycotoxin-producing fungi as fermentation starter and monitor mycotoxins during fermentation.
