Hold On, Is Canned Tuna Cooked Or Raw?
By Greta Pano
If you're a fan of canned tuna, you'll be happy to know it's safe and ready to eat straight out of the can since it is pre-cooked for your convenience.
The process of canning tuna typically starts with frozen tuna that arrives at the facility straight from a catch, which is subsequently thawed and steamed in large batches.
After cooking and cooling, the tuna is skinned and deboned, and the meat is canned with salt and liquids such as oil, water, or vegetable broth.
The cans are then vacuum-sealed and sanitized to kill bacteria. This contributes to tuna cans' long shelf life, which typically lasts two to five years.
Fresh tuna is often served raw or rare, but cooked canned tuna lasts long, doesn't have to be refrigerated before opening, and is perfect for salads, sandwiches, and casseroles.
