Needle Sandwiches Served on Delta Airlines

Sewing needles found in 6 sandwiches served on flights from Amsterdam

Delta Air Lines officials and the FBI are opening up a criminal investigation after half a dozen sewing needles were found in sandwiches served on four separate Delta flights on Sunday.

The needles were found on flights from Amsterdam to Minneapolis, Atlanta, and Seattle. One passenger was injured.

"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," said Delta Air Lines in a written statement to The Daily Meal.

The sandwiches were prepared by airline catering company Great Gourmet, which provides more than 200 million meals a year for customers at 120 airport locations around the world.

The needles were found inside turkey sandwiches and upon discovery, passengers ordered pizza instead, according to The Huffington Post.

"Delta requires all its in-flight caterers to adhere to strict criteria in order to offer our customers the very best onboard meals. The safety and security of our passengers and crew is Delta's number one priority," said Delta Air Lines in its written statement to The Daily Meal.

James Tonges, the injured passenger who bit into one of the needle sandwiches on a flight to Minneapolis, told ABC News on Tuesday that he is now receiving antiretroviral drugs used for treating HIV.
