One of the 10 passengers was taken by ambulance to Hawaii Medical Center East, Ishikawa said.

"All of them had symptoms of vomiting, but no symptoms of fever, which would have indicated something more serious," Ishikawa said. "I'm not sure if the food was consumed on the plane or elsewhere. But you have to quarantine the plane to make sure it's nothing more serious."

Flight JQ001 arrived from Melbourne at 8:45 this morning and was parked in a new quarantine area at the 'ewa end of the airport's concourse as a precaution, Ishikawa said.

"Any time we have a plane with a number of people sick, we have the plane park at the far end of the airport as a quarantine area we're putting together," he said.

Ishikawa had no immediate count of the number of passengers aboard the Airbus A330-200 wide body jet.

U.S. Public Health officials cleared all of them to leave the plane about 10 a.m., Ishikawa said.

Jetstar is based in Melbourne and advertises itself as Australia's and Singapore's newest low-fare airline for Australia and the Asia-Pacific.
