THE HAGUE (AP) — Police at Amsterdam's Schiphol Airport have opened a criminal investigation into how needles got into turkey sandwiches served to passengers on Delta Air Lines flights from Amsterdam to the United States, a spokesman said Tuesday. The FBI also is investigating the incidents.
Delta said what appears to be sewing needles were found in five sandwiches on Sunday. One passenger on a flight to Minneapolis was injured. The other needles were on two flights to Atlanta and one to Seattle.
"We are keeping all options open because at this moment we have no idea why somebody or something put needles inside the sandwiches, so that is what we have to investigate," airport police spokesman Robert van Kapel told the Associated Press in a telephone interview.
The sandwiches were made in the Amsterdam kitchen of catering company Gate Gourmet. The company's listed address in the Netherlands is in the Schiphol area, where the Dutch capital's airport is located.
Gate Gourmet's website says the company handles more than 3 million airline flights each year.
The company issued a statement Monday saying, "We take this matter very seriously, and we have launched our own full-scale investigation." It also said it was "heightening our already stringent safety and security procedures, to prevent any recurrence."
The company also said it is "treating this as a criminal act" and stressed it is "cooperating fully with investigations by local and federal authorities and by our customer."
Dutch authorities have no indication the incident is linked to terrorism, and Mr. van Kapel said he had no information on whether there had been any blackmail threats made to the airline or catering company.
The FBI said its Atlanta office has opened a criminal investigation.
Passenger Jim Tonjes of Plymouth, Minn., told the Minneapolils Star Tribune newspaper that he felt a sharp poke in his mouth after biting into his sandwich.
"I figured it might be a toothpick," he said, but instead it was a 1-inch needle that had punctured the roof of his mouth.
"It looked like a sewing needle but without an eye. ... I was in shock," he told the newspaper. "I thought, 'Oh, my God.' It's the last thing you expect in a sandwich."
Delta spokeswoman Kristin Baur said Monday that flight attendants stopped serving the sandwiches as soon as the needle was discovered. Messages went out to other flights en route from Amsterdam. Another sandwich served on the Minneapolis-bound flight also had a needle, Ms. Baur said.
After the needles were found, passengers got pizza instead.
Ms. Baur said security for its meal production has been increased and the airline is using more prepackaged food while the investigation continues.
"Delta is taking this matter extremely seriously and is cooperating with local and federal authorities who are investigating the incident. Delta has taken immediate action with our in-flight caterer at Amsterdam to ensure the safety and quality of the food we provide onboard our aircraft," the airline said in a written statement.
Benno Baksteen, a former Dutch pilot and aviation safety expert, said food is transported to aircraft amid tight security, "for obvious reasons — because people can hide stuff in catering trolleys."
He said trolleys carrying prepared airline food are sealed in transport, "so the most likely place where it could have happened would be in the place where it's manufactured or, of course, before it's served, once the trolleys are opened."
Schiphol Airport staff referred questions about security surrounding catering companies to the Dutch Ministry of Security and Justice, which oversees aviation security. A spokesman at the ministry was not immediately available for comment.
Ton Scherrenberg, chairman of the VNC union, which represents some 7,000 Dutch cabin personnel, told the AP that cabin crews check food trolleys for foreign objects when they open them on board aircraft, "but you can't check every single sandwich."
He said he knew of no other such incidents at Schiphol in the past.
