Quality is the limit, not safety.** High-acid (tomatoes, fruit): 12-18 months for quality. Low-acid (vegetables, meat): 2-5 years Canning sterilises the contents and seals them, so provided the seal holds nothing can get in. Cans recovered from a steamboat that sank in 1865 were analysed a century later and found still free of microbial growth, though nobody suggested eating them. High-acid contents corrode the can from the inside over years, which affects taste and eventually integrity. The only genuinely dangerous can is a damaged one: bulging, leaking, badly rusted, or with a deep dent on a seam, all of which can indicate a broken seal and, in low-acid foods, the possibility of botulism. ## How to store it - Cool and dry. Heat is what shortens canned shelf life. - Never store opened cans in the can — transfer to a container. ## How to tell it has gone - Bulging, spurting on opening, leaking or deep seam dents: discard without tasting. - Surface rust is fine; rust that pits through is not. > "Use by" and "best before" are legally different. Use-by is a safety date and should be respected; best-before is about quality, and food is usually fine well past it. Where the two diverge matters, the page above says which applies. ## Common questions ### Does Canned food expire? An intact, undamaged can is safe more or less indefinitely.
