The cans should be properly sealed and should not have any sign of rusting. The canned tuna contains some liquid such as pickled sauce, olive oil, and Catalan sauce.
These liquids may cause the tuna inside the cans to spoil faster if they are not stored in dry places. Moisture would increase the bacteria growth in the canned tuna. Therefore, people should avoid storing canned tuna in wet or moisture-rich places. The sterilization process ensures that the canned tuna has no pathogens.
