Authorities in the U.S. and Netherlands are investigating how needles were inserted into the sandwiches served to passengers on four Delta Airlines flights, CBS reports.
Travelers on four separate flights out of Amsterdam were served turkey sandwiches with what appeared to be sewing needles in them, and one passenger was injured when a needle punctured the roof of his mouth. All four flights were en route to the U.S., prompting the FBI to begin an investigation into the matter with the help of Dutch authorities.
The sandwiches were made in Amsterdam by Gate Gourmet, which describes itself as the world's largest independent provider of airline catering.
The injured passenger, Jim Tonjes of Minnesota, is on medication and is being monitored for hepatitis and HIV, he told the Minneapolis Star Tribune. He discovered the needle after biting down onto a sharp object in his sandwich.
"I figured it might be a toothpick," he said. "It looked like a sewing needle but without an eye. ... I was in shock. I thought, 'Oh my God.' It's the last thing you expect in a sandwich."
Tonjes said his son also found a needle in his sandwich.
Delta, Gate Gourmet, and both Dutch and American investigators are looking into the matter.
