Federal prosecutor Jerome Gorgon described the events as "a serious concern for national security": "These two foreign nationals have been charged with smuggling a fungus described as a potential agroterrorism weapon into the heart of the United States, where they apparently intended to use a University of Michigan laboratory to advance their plan."
The investigation was carried out by the FBI and Customs and Border Protection (CBP). Its director of field operations, Marty Raybon, emphasized the seriousness of the attempt to introduce harmful biological materials into the country:
"These charges are an indication of CBP's crucial role in protecting the American people against biological threats that could devastate our agricultural economy and cause harm to human beings."
Raybon thanked the "tireless work" of the CBP and FBI teams that managed to thwart what could well have been a covert biological strike at the heart of the North American scientific system.
As of Tuesday afternoon, Jian was still listed as a researcher on the University of Michigan website. The university did not issue statements despite being contacted by the press.

This episode occurs in a climate of growing geopolitical tension, where the Trump administration has taken measures against foreign students linked to anti-American activities or with ties to hostile regimes. Last week, Secretary of State Marco Rubio announced that the government will "aggressively" revoke visas of Chinese citizens, particularly those with connections to the CCP or studying in sensitive areas.
In a post on his X account, Kash Patel reaffirmed:
"The FBI arrested a Chinese citizen who allegedly smuggled a dangerous biological pathogen into the U.S. [...] This case is a cautionary reminder that the CCP works day and night to infiltrate our institutions and attack our food supply, putting our economy and our lives at serious risk."
National security of the United States is threatened this time from within its own academic system, by agents linked to the Chinese communist regime. It did not arrive in the form of cyberattacks or from the airspace, but hidden in a vial, smuggled clandestinely through the Detroit Metropolitan Airport. Two Chinese citizens have been charged with smuggling a pathogenic fungus considered a "potential agroterrorism weapon", allegedly intending to research it inside a laboratory at the University of Michigan.
Alarms were raised at the highest level of the U.S. government, which considers this incident part of a hostile strategy by the Chinese communist regime to infiltrate its agents into key institutions of the country.

The FBI Director, Kash Patel, told the media that the case represents "a direct threat to national security." For Patel, this episode is not isolated, but part of a dangerous covert offensive by the Chinese Communist Party (CCP) to attack the U.S. food system:
"This case is a sobering reminder that the Chinese Communist Party continues to deploy agents and researchers to infiltrate our institutions and attack our food supply, an act that could cripple our economy and endanger the lives of Americans," stated the head of the Federal Bureau.
The accused are Yunqing Jian, a postdoctoral researcher at the University of Michigan, and her partner, Zunyong Liu, both citizens of the People's Republic of China. According to the Department of Justice, they are charged with conspiracy, smuggling goods, making false statements, and visa fraud. The prosecution claims that they smuggled a fungus called Fusarium graminearum, classified as an agroterrorism agent due to its ability to cause "head blight," a devastating agricultural disease that affects crops such as wheat, corn, rice, and barley. This disease causes estimated economic losses of billions of dollars annually worldwide and also poses a threat to human and animal health, causing vomiting, liver damage, and reproductive disorders.
The prosecution also revealed that Jian received direct funding from the Chinese government for her research on the fungus, and that evidence of her loyalty to the CCP was found on her electronic devices. Liu, meanwhile, works at a Chinese university conducting studies on the same pathogen and, according to the complaint, initially lied to customs authorities but later confessed to bringing the substance into the U.S.
