Mangosteen
Prohibited in: United States (Until 2007)
Justification: Risk of fruit flies
Mangosteen, a tropical fruit native to Southeast Asia, was banned in the United States until 2007 due to concerns about fruit fly infestations. The USDA feared that the fruit could harbor invasive species that would threaten U.S. agriculture. After rigorous inspection protocols were established, the ban was lifted, and mangosteen is now available in certain U.S. markets.
