Delta Air Lines Inc. is investigating how needles got into turkey sandwiches on four flights from Amsterdam to the US.
According to the Associated Press, the airline admits needles were found in six sandwiches on flights this Sunday. The needles were found on planes enroute to Minneapolis, Atlanta, and Seattle.
The Wall Street Journal reported a passenger on one of the flights was injured but declined treatment after the plane landed in Minneapolis.
"Delta is taking this matter extremely seriously and is cooperating with local and federal authorities who are investigating," Delta said in a statement. "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 sandwiches were made in the Amsterdam kitchen of catering company Gate Gourmet, and were to be served to business class passengers on Delta flights.
Gate Gourmet spokeswoman Christina Ulosevich said the company has gotten no reports of similar incidents on any of the other airlines it serves out of Amsterdam. She said the company did not yet know how the needles got into the sandwiches.
Gate Gourmet issued a statement 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."
Delta operated 17 flights from Amsterdam to the US on Sunday and again on Monday.
