Canned sardines don't go bad quickly due to the canning process, which involves sealing them in an airtight environment and then sterilizing them through high-heat processing. This eliminates bacteria and microorganisms that typically lead to food spoilage. Additionally, the lack of oxygen inside the can prevents the growth of aerobic bacteria, further prolonging their shelf life when stored properly.
