A dangerous fungus meant to destroy crops is at the center of a high-profile case in the United States. Two Chinese nationals, Yuning Jian and Zunyong Leu, are facing serious federal charges including conspiracy, smuggling, and visa fraud, after allegedly bringing the crop-destroying fungus Fusarium graminearum into the country.
The fungus infects wheat, rice, corn, and barley, causing “Fusarium head blight,” which destroys the grain and produces toxins harmful to humans and animals. The FBI claims both suspects had previously researched the fungus in China. Leu allegedly tried to bring infected plant material into the US last July, claiming at first not to know what it was but later admitting he brought it for research at a University of Michigan lab, where Jian worked.
Text messages and articles found on Leu’s phone suggest both were interested in the concept of “plant pathogen warfare.” Authorities fear this could be a case of agroterrorism—using biological agents to attack a country’s food supply and destabilize its economy. The case highlights the vulnerability of global food systems and the growing risks posed by bioterrorism.
If convicted, the two could face long prison sentences. The University of Michigan denies any Chinese funding for their research and is cooperating fully with the investigation.
