What threats does a company screen for?

With the six needles present in sandwiches on international Delta Air Lines flights from the Netherlands to the United States, it is a query already stressed travelers are beginning to ask. Assuming you get any food on your flight these days, how do you know it is safe to eat?
Each country is responsible for setting its own in-flight catering rules, says Perry Flint, a spokesman for the International Air Transport Association, an airline industry group. The United Nations' International Civil Aviation Organization also has standards and guidance on catering security.
The Transportation Security Administration declined to specify its catering rules "so as to not violate the integrity of these measures," TSA spokesman David Castelveter wrote in an e-mail. "TSA conducts ongoing inspections to make definite airlines and contractors comply with these security requirements." At foreign airports, the TSA's role "is as an evaluator of those programs."


including Delta, would comment on specifics of how food moves from manufacturing plants and commercial food kitchens to their airplanes. Nor would of the largest airline catering companies, including Gate Gourmet, which supplied the turkey sandwiches under inquiry.
Gate Gourmet said it is "cooperating fully with investigations by local and federal authorities and by our customer. As such, further details of this matter must stay confidential" and referred to its net site for information on safety procedures.
