Two researchers charged with smuggling dangerous fungus into the US

In July 2024, Yunqing Jian, 33, and Zunyong Liu, 34, both Chinese nationals, were implicated in a federal investigation due to their alleged smuggling of a noxious fungal pathogen, Fusarium graminearum, into the United States for research purposes. Jian was a postdoctoral researcher at the University of Michigan, while Liu was associated with a university in China. They were arrested following suspicions that Liu transported the fungus through the Detroit Metropolitan Airport with the intention of using the pathogen for research at Jian's lab. Authorities indicated that the pathogen is recognized as a potential agroterrorism weapon, capable of causing severe agricultural damage and public health issues. The investigation revealed that Jian had received funding from the Chinese government for her research. Further analysis of Jian's electronic devices uncovered content supporting her loyalty to the Chinese Communist Party. Investigators highlighted Liu's attempt to mislead airport officials during his initial questioning about the materials he carried, although he later confessed to purposefully concealing the fungal samples in his luggage. The situation has raised significant concerns regarding national security, especially relating to the potential ramifications of compromised agricultural integrity and food supply. The U.S. Attorney's Office stated that the charges included conspiracy, smuggling goods, false statements, and visa fraud. Both individuals face the prospect of severe legal consequences if convicted, as authorities emphasize the importance of safeguarding American agriculture and public health against such threats.
