How Long Does Unopened Canned Meat Really Last For?

We all have those mildly suspect cans of meat dwelling in the depths of our pantries, unsure of how long they've been there and what we'll actually find inside if we ever open them up. Canned meat and fish can be an excellent source of protein, especially in emergency scenarios when we can't rely on electricity. But how long does that canned meat really last? According to the U.S. Department of Agriculture, low-acid canned foods like meat will keep at good quality for two to five years, but that doesn't guarantee they'll taste all that good.

If you check your groceries, you'll notice a label marking some sort of expiration date — but the dates on canned goods won't always give you a straight answer as there is a slight difference between sell-by and use-by dates. You may also see a "best by," which is similar to sell-by and tells you the amount of time the meat will maintain its quality. This date indicates when your meat may stop tasting, smelling, and looking as good as when it was first canned.

The other label will say "use by," which references the approximate date of when the product maxes out its peak flavor and freshness. Taking note of these dates, and what they actually mean, will help you determine whether to keep a can around for a bit longer or swap it out for something newer.

No matter the type of canned meat — whether it's the best or worst type to buy — safety must be a top priority. First, cans should be stored in a cool (not too cold) and dry space to avoid bacteria growth, which is why you should never eat canned food that was accidentally frozen – the seal breaks, risking the contents entirely.

Second, while it's important to look for the "best by" and "use by" dates, there are also physical signs you should look for on the cans. Damage to the can such as dents, unnatural bulges, or holes are obvious signs, as are leaks and rust. Be sure to check the condition of the meat as well in case of any discoloration or changes in texture. 

It's also important to note that the two-to-five-year timeline exclusively applies to mass-produced factory canned meats. Per the USDA guidance, home canned foods of all kinds should be used within a year — so for those who may be prepping canned meals that include meat, be sure to replace those much more frequently.
