Chinese Citizens Charged with Smuggling Deadly Fungus into the U.S.

Two Chinese nationals have been arrested, accused of attempting to smuggle harmful pathogens into the United States. One of them, Yunqing Jian, a post-doctoral research fellow at the University of Michigan, allegedly transported Fusarium graminearum, a fungus known for its negative impact on crops and potential health risks. This incident reportedly occurred in 2022.

An arrest affidavit reveals that Jian and her boyfriend, Zunyong Liu, discussed their smuggling plans over WeChat. Liu guided Jian on how to conceal the fungus. In one conversation, Jian mentioned stuffing the fungus into her boots, expressing concern about limited space due to only having one pair of shoes.

The fungus has been associated with “head blight,” affecting wheat, barley, corn, and rice, which costs billions globally. It’s also toxic, with the potential to cause severe health issues in humans and animals.

Since starting her research in the U.S., Jian has attempted similar smuggling operations. She even told a third party she mailed materials before without issues. In one case, a package was intercepted before reaching its destination, hidden inside a statistics textbook.

Further attempts to smuggle the fungus continued with Liu’s recent entry into the U.S. in July 2024. He came under the pretense of visiting Jian but was flagged by customs. The search of his luggage uncovered materials associated with Fusarium graminearum.

After initially denying any intention to carry pathogens, Liu eventually confessed to authorities. He also revealed that he intended to use the same lab as Jian for his research.

Both Jian and Liu now face multiple charges, including conspiracy and visa fraud. This arrest has raised concerns about potential threats to national security, as officials note the ongoing infiltration by foreign agents targeting vital sectors like food supply. FBI Director Kash Patel emphasized the seriousness of this situation, commending law enforcement for averting a public health crisis.

The University of Michigan has responded, stressing its commitment to research integrity and national security. They condemned any actions that could cause harm, clarifying that they did not receive any funding from the Chinese government related to the accused activities and are cooperating with ongoing investigations.
