Meat, seafood and other non-liquid food items are permitted in both carry-on and checked bags. If the food is packed with ice or ice packs in a cooler or other container, the ice or ice packs must be completely frozen when brought through screening.

Bringing meat on an international flight is subject to extremely strict customs and agricultural regulations that vary by destination. Generally, most countries prohibit travelers from bringing fresh, chilled, or frozen meats (including poultry and pork) from other nations to prevent the spread of diseases like Foot-and-Mouth Disease or Swine Fever. For example, if you are flying into the United States, fresh meat is almost universally banned from most regions, though some "shelf-stable" or vacuum-packed items from specific countries (like Canada) might be allowed. In the European Union, rules are similarly tight regarding meat from outside the EU. The most important rule is to always declare any food items on your customs form. If you declare a prohibited meat item, it will simply be confiscated and destroyed without penalty. However, if you fail to declare it and are caught by a "sniffer dog" or X-ray, you can face massive fines ranging from $300 to over $1,000 and may lose your global entry or trusted traveler status.
