Canned or pouched tuna is cooked inside the sealed container. This is how canning anything works. Once the food is inside the sealed can or jar or pouch, the temperature is raised to a certain degree for a specific amount of time. This kills any bacteria or other microorganisms that may be in the food.
How is tuna in a pouch preserved?
