U.S. federal prosecutors have charged two Chinese nationals with smuggling a hazardous biological pathogen into the country for research purposes. The pathogen, identified as Fusarium graminearum, is a fungus known for causing “head blight” in crops, leading to substantial economic losses worldwide.
According to the U.S. Department of Justice, Zunyong Liu, a 34-year-old researcher currently located in China, brought the dangerous fungus with him when he traveled to Michigan in July 2024 to visit his girlfriend, Yunqing Jian, who is 33 years old and employed at a University of Michigan laboratory. Liu has reportedly confessed to smuggling the fungus to conduct research at the university.
An FBI complaint indicates that Liu and Jian had previously communicated about the possibility of shipping biological materials and discussing research topics before Liu’s arrival in the U.S. They have been charged with conspiracy, smuggling, providing false statements, and visa fraud.
Cheyvoryea Gibson, special agent in charge of the FBI’s Detroit Field Office, stated that the actions of the accused “posed an imminent threat to public safety.” Jian was scheduled to appear in court in Michigan to face the charges.
This case highlights the increasing vigilance of U.S. law enforcement agencies in monitoring biological threats and the potential for foreign entities to exploit scientific research. The seriousness with which these charges are being treated reinforces the critical importance of safeguarding not only agricultural assets but also public health against possible agroterrorism threats.
The handling of this case can serve as a reminder of the challenges that come with international research collaboration, especially when it involves sensitive biological materials. Strengthening oversight and regulations may enhance the security of research institutions and help prevent future incidents.
