Fungus Smuggling: Chinese Nationals Charged | US DOJ
Two Chinese nationals face serious charges, as the U.S. Department of Justice reveals they allegedly smuggled a perhaps risky fungus into the country, raising serious questions about biosecurity and potential agroterrorism. The smuggled Fusarium graminearum is classified as a potential agroterrorism weapon. Yunqing Jian and Zunyong Liu, funded by the Chinese government, reportedly brought the fungus into the U.S. via Detroit Metropolitan Airport, intending to conduct research at the university of Michigan. Facing federal charges, their actions have sparked concerns about the safety of the U.S. agricultural sector. News Directory 3 will continue to monitor developments.

Chinese Nationals Charged with Smuggling Potential Agroterrorism Weapon
Updated june 03, 2025
Two Chinese citizens are facing federal charges for allegedly smuggling a fungus, identified as Fusarium graminearum, into the United States. The Justice Department (DOJ) announced Tuesday that the fungus is classified in scientific literature as a potential agroterrorism weapon. The case highlights concerns about biosecurity and potential threats to the U.S. agricultural sector.
Yunqing Jian, 33, and Zunyong Liu, 34, both citizens of the People’s Republic of China, are accused of receiving funding from the Chinese government for their research. Some of this research was conducted at the University of Michigan, according to officials.
According to the DOJ, JianS electronics contained data indicating her membership in, and loyalty to, the Chinese Communist Party. Liu,identified as Jian’s boyfriend,is employed at a Chinese university where he researches the same pathogen.He initially denied, but later admitted to, smuggling the Fusarium graminearum into the U.S. through Detroit Metropolitan Airport. He intended to conduct research on it at the University of Michigan laboratory where Jian worked.
The FBI has stated that Fusarium graminearum causes “head blight,” a disease affecting wheat, barley, maize, and rice. This disease results in billions of dollars in economic losses globally each year. The smuggling of this fungus raises meaningful national security concerns.
“The alleged actions of these chinese nationals — including a loyal member of the Chinese Communist Party – are of the gravest national security concerns.These two aliens have been charged with smuggling a fungus that has been described as a ‘potential agroterrorism weapon’ into in the heartland of America, where they apparently intended to use a University of Michigan laboratory to further their scheme,” U.S.Attorney Jerome gorgan said.
Marty C.Raybon, U.S. Custom and Border Protection, Director of Field Operations, emphasized the importance of border security in preventing biological threats. The charges against Jian and Liu highlight the role of Customs and Border Protection in safeguarding the U.S. agricultural economy and public health.
“Today’s criminal charges levied upon Yunqing Jian and Zunyong Liu are indicative of CBP’s critical role in protecting the American people from biological threats that could devastate our agricultural economy and cause harm to humans; especially when it involves a researcher from a major university attempting to clandestinely bring potentially harmful biological materials into the united States,” U.S. Custom and Border Protection, Director of Field Operations Marty C. Raybon said.
Jian is scheduled to appear in federal court in Detroit for her initial hearing.
What’s next
The investigation is ongoing, and further details are expected to emerge as the case progresses through the legal system. Authorities are likely to review security protocols at research institutions and border control measures to prevent similar incidents in the future. The focus remains on preventing agroterrorism and protecting U.S. agriculture from potential threats.
