Breakouts of Fusarium graminearum infections already naturally occur in dozens of U.S. states — basically any state that produces wheat and barley — and has been established in the U.S. for at least 125 years, Caitlyn Allen, a professor emeritus of plant pathology at the University of Wisconsin-Madison, told ABC News. In addition, the U.S. Department of Agriculture keeps a list of potential agroterrorism agents, and Fusarium graminearum is not on that list, Allen said.
“We’re not talking about something that just got imported from China,” Allen said. “People should not be freaking out.”
