Orange juice futures surged Friday on concerns that federal regulators might restrict imports from Brazil.
Orange juice for March delivery rose 10 cents, the maximum amount allowed in daily trading, to close at $2.1065 per pound. The price is near a record high.
Traders are worried that juice imports from Brazil could be halted if the U.S. Food and Drug Administration finds traces of a banned fungicide. The FDA started testing for the fungicide this month after low levels were detected in juice supplies. The fungicide is not approved for U.S. consumption, but is used in Brazil.
The FDA said Friday that several recent tests didn't find traces of the fungicide, but inspections are ongoing.
While the FDA did not find any positive traces of the fungicide, carbendazim, traders are nervous because the testing is ongoing, said Justin Honrath, an analyst with CPM Group in New York.
What makes investors edgy is the lack of transparency for FDA's testing regimen, Honrath said. Investors worry that a surprise announcement of an import ban could be around the corner. "Of course, everyone is going to look at the worst-case scenario," he said.
