LOS ANGELES, CA (Catholic Online) - An investigation into the discovery of the needles in four turkey sandwiches has been launched by the FBI. The needles were discovered en route from Schiphol Airport in the Netherlands to Minneapolis, Seattle and two flights to Atlanta.

Delta Spokeswoman Kristin Baur says that two of the needles were found by passengers, at which point Delta told all 18 flights from Amsterdam to stop serving the sandwiches.

One passenger on the plane going to Minneapolis was injured by the needle but declined medical treatment upon landing.

Gate Gourmet, which provided the sandwiches to Delta, says the sandwiches originated at the firm\'s facility in Amsterdam.

\"This is a terribly upsetting situation," Gate Gourmet spokeswoman Christina Ulosevich says. \"First and foremost is the safety of the traveling public. There\'s nothing more important to us at all than the safety of the passengers and crews.\"

In response, Delta is now serving sealed prepackaged food on these flights instead of the sandwiches, and no other needles have been found.

The Transportation Security Administration has notified all U.S. airlines with flights from Schiphol to the United States of the findings.

\"TSA continues to closely monitor the review of the incidents as well as the security protocols being conducted by the air carrier and the airport authority,\" spokesman David Castelveter said.

\"Delta requires all its in-flight caterers to adhere to strict criteria in order to offer our customers the very best onboard meals,\" Baur told CNN in a statement. \"The safety and security of our passengers and crew is Delta\'s number one priority.\"

Asked whether Gate Gourmet had taken any actions have been taken against any employee, Ulosevich said, \"We don\'t have any comment. It\'s part of an active investigation.\"

\"We are absolutely cooperating fully with federal and local authorities who are involved, and concurrent with that, we\'ll be conducting our own full-scale investigation.\"
