In a Seattle airport, it would seem that someone transported some chicken on their flight. Totally legal thing to do, as long as it’s packed up right. Unfortunately for other passengers, it was not, and the contents of the once packaged RAW chicken was accompanying their bags on the conveyer belt.
The TSA thinks it happened when airport workers were throwing luggage onto the belt for distribution. The raw chicken was probably in a package that was loosely secured, and that’s why it fell out onto the conveyer belt. You can tell from the square shape it was once packed up in either luggage or a box.
It honestly reminds me of a a cartoon when a character gets put into a box and then walks out waddling in a square shape.

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. If the ice or ice packs are partially melted and have any liquid at the bottom of the container, they will not be permitted. You also can pack frozen perishables in your carry-on or checked bags in dry ice. The FAA limits you to five pounds of dry ice that is properly packaged (the package is vented) and marked.
TSA Guidelines On Meat Transportation
Well anyway, the TSA put out a video of the incident reminding people that you can travel with chicken, just make sure it’s not “Free Range.” Unless of course it’s your live pet chicken which I assume would be acceptable in just a crate.
