When Do Beans Go Bad
Beans can go bad quickly if not stored properly. Beans should be stored away from direct sunlight in a cool and dry place. You should store them in the refrigerator in an airtight container. You should also not refrigerate cooked beans otherwise they will turn black.
If your beans have not softened at all, repurpose them for pie weights, or toss them into the compost bin. You should never forget to remove bean ends, either snapping them or cutting them off with a knife, so they will not rot. If you are going to use your beans in the future, it is best to rinse them with running water before you store them.
For fresh beans, you are best off keeping them in the refrigerator, or you can alternatively freeze them if you do not expect to use them anytime soon. As long as you keep the beans in the pods, fresh beans will last three to five days in your refrigerator. Once cooked, most beans last several days in your refrigerator, or you can stretch that out further by popping them into your freezer. As mentioned, keeping cooked beans in a sealed container and keeping in the refrigerator will help keep them going for up to four days.
Cooked beans will last in the refrigerator for three to five days, meaning that you should date your leftovers and discard them if they are past this date. When you need another serving of beans, move them from your freezer to your refrigerator and let sit there for about 24 hours, and they will be ready for cooking the next day. Doing this keeps in the moisture and allows the beans to retain that same fresh cooked flavor, when you take the beans out of the freezer again. I would suggest having a few beans on hand for your meals the next two days, keeping two to three portions in your refrigerator.

You can help dried, canned beans keep fresher longer by keeping them in the pantry (a cool, dark area) at temperatures below 75 degrees F. If your navy beans are dried, you can store them for years in a dry container, but try to use them often. You can store dried beans in a pantry for years, and they should still be fine, but after two to three years, they are more likely to have lost their nutritional value. Dried beans are listed as non-permanent, but will start losing their moisture after 1 or 2 years in the pantry.
Of course, once you crack the bag open and expose beans to air, they slowly start expiring, and after 1-2 years in the pantry, they will start losing moisture, eventually turning squishy. If kept for too long, dried beans eventually get so tough no amount of soak or cooking can soften them. If you have a bag of dried beans sitting in your pantry whose best-by date has passed, you are going to need to soak and cook them for much longer than it will take to prepare a new bag.
If your dried beans are older than 2 years since their best by date, they will have to be soaked and/or cooked longer than recommended. Since beans are likely going to stay there a long time, you may want to mark them according to their storage dates to make it easier for you to use them later. No matter which kind of beans you are storing, as long as they are dry and unopened, they should last an unlimited amount. You may want to salvage these beans by either sopping them longer than recommended, or cooking them longer, which should help to revive them slightly while cooking the beans.
To make matters worse, you actually have to soak and cook beans before you can evaluate their quality. If you find that you are cooking your soaked beans for over two hours, but they simply do not get soft, then maybe it is the beans…not you. The good news is that if your beans are at about the five-year-old-old-mark, they will still make a tasty dish. As long as you stored the beans correctly, and there is no evidence of deterioration, you can safely eat your expired beans.

To ensure the dried beans are kept as fresh as possible, store them in a food-safe storage container with tight-fitting lids, not the plastic bag in which you purchased them. Dry beans, sealed inside an oxygen-absorbing Mylar bag and placed inside a sealed plastic barrel, will store well for 25 to 30 years in ideal storage conditions.
Oxygen absorbers help keep the beans free from oxygen and insects, and Mylar bags are great at keeping out light, humidity, and gases. This barrier prevents the air from damaging the beans too early, so you do not need to worry about your beans drying out or holding on unwanted humidity. As we mentioned, beans really need a little bit of attention, and following all of the rules like keeping it out of moisture and out of air, you can make sure that your beans stay whole.
Wait until your beans are cooked to add salt or any acidic foods, like tomatoes. If you do not want to waste any of the re-roasted pinto beans, put them in the refrigerator for at least two hours, or store them in the hot slow cooker container. Properly stored, dried pinto beans typically will stay good quality for around two or three years at normal room temperature, though generally will still be safe for use beyond this time.

On average, cooked, fresh green beans, such as bell peppers, last from five to seven days in the fridge when stored with cooked, fresh green beans in a crisper drawer. Sealed tightly against oxygen, expect storage to be eight to 10 years with stable temperatures of 70 degrees F. Dried beans should last proportionally longer when stored cooler. Dried-packed beans stored longer than 12 months will lose moisture and may need more time to cook.
How do you tell if cooked beans have gone bad?
Your nose and sight are typically the most accurate tools to determine whether your beans have gone bad, however, they are not a perfect test. A sour scent and a white liquid surrounding the beans are indicators of improperly cooked beans.
How do you know if beans are bad?
Seeing bugs or mold on beans indicates that they are bad, though beans don’t officially go wrong. You should also discard them if they smell sour. Beans are spoiled if their color has turned brown or brownish or if they have a rotten odor along with a brown and brownish color.
How long does it take beans to go bad?
There is a time limit attached to opening those beans, but once they are opened, the clock begins to run! The USDA recommends that, despite the temptation of storing open beans in the refrigerator for three to four days, you transfer them to plastic or glass containers before storing them in the fridge.
