Chinese Researchers in Custody Over Fungi Smuggling Allegations
Recent reports reveal that Chinese researchers are currently in custody related to accusations of attempting to smuggle harmful fungi into the United States. These fungi have the potential to severely damage crops.
Yunqing Jian, 33, attended a detention hearing in Detroit on Thursday. During this session, her public defense attorney questioned when she might be able to secure private counsel.
The judge decided to hold another detention hearing on June 13, allowing Jian, who is a researcher at the University of Michigan and a Chinese citizen, to remain in custody until then. CBS News provided updates on this case.
Jian’s arrest on June 3 followed an incident involving her boyfriend, Zunyong Liu, who was intercepted by customs last July while returning from Shanghai. Liu was discovered carrying samples of Fusarium graminearum, a fungus that poses a significant threat to American agriculture if it mutates to resist treatment.
The risk posed by these fungi has been underscored by officials from the Trump administration, who described the situation as a direct threat to American food security.
Last summer, Jian was involved in research funded by the Chinese government. When questioned, Liu initially attempted to conceal the fungal samples. Eventually, he admitted that he wanted to study them at the University of Michigan laboratory, where Jian had previously conducted research.
During the investigation, agents found materials on Liu’s phone titled “Plant Pathogen War,” which included alarming details about Fusarium graminearum and its potential economic impact on crops worldwide.
Following his encounter with customs, Liu was barred from entering the U.S. and returned to China. Jian was later interviewed by the FBI in February, claiming she only learned of Liu’s plans upon his detainment at the airport.
However, evidence suggests otherwise. Communications between Jian and Liu indicate discussions about smuggling the fungi into the U.S. had been ongoing since at least 2022. In 2024, Jian even signed a document expressing support for the Chinese Communist Party and its leadership.
Both Jian and Liu face conspiracy charges related to the smuggling of a potentially dangerous fungal pathogen. Notably, while Fusarium graminearum is already found in the U.S. and causes annual losses between $200 million and $400 million in agriculture, experts warn that it could escalate the risks to the food supply if altered for increased resistance or toxicity. Dr. Richard Ebright, a molecular biologist at Rutgers University, emphasized this concern.
