Despite popular belief, this isn't the ideal place to keep your cherished fish.
If you want to avoid the hassle of waiting for tuna to cool down, you should stock up on cans and keep them in the fridge for when hunger hits.
Is it ever true that canned tuna goes bad?
Well, canned tuna may go bad faster if you keep it in a cupboard that's close to the oven or stove.
It goes bad faster if it gets too hot inside the can, and
if you cook using your oven or stovetop in close proximity to the pantry, that means your canned tuna will get even hotter.
Putting canned tuna in the fridge will keep it from spoiling before its time.
