For the businessperson or tourist traveling across the United States, kosher certified products are available almost everywhere, even in the smallest groceries in the most remote towns. However, it is much more difficult to obtain reliably kosher certified products in most foreign countries.
A traveler bringing along frozen (T.V.) dinners where only non-kosher ovens are available for reheating, may use the ovens by covering the frozen package with two layers of aluminum foil. If a microwave will be utilized, then the food must also be double wrapped. Kosher meals should be ordered in advance when traveling by plane, train or ship. These meals are also heated in non-kosher ovens. The employees of the carrier are instructed to heat these meals in the same manner that they were received; totally wrapped in double foil with the caterer’s seal and the Rabbinic certification seal intact. The traveler can ascertain by the intact seals that the dinners have not been tampered. Any dinner, which is not properly sealed, should not be eaten. The kosher certification only applies to the food in the sealed package.
Any other food (rolls, wines or liqueurs, cheeses, and coffee creamers or snacks) served loose by the carrier is not included in the kosher endorsement, unless it is sealed and bears its own separate endorsement.
