Brown spots on green beans may be something you might have experienced as a gardener. But do you know for sure what the reasons are for your beans to start changing color? This is what we are about to find out in this post.
Green bean is a type of common bean that comes from different cultivars. Green beans have different common names they go by and some of these names include snap beans, string beans, and French beans.
You can add green beans to any type of healthy diet, or almost any eating plan and this is thanks to their low-calorie and fat contents.
Green beans are also fairly easy to grow and they grow in either a bushy manner or a climbing manner. But some situations may arise that causes your green beans to turn brown and this can have you wondering what the cause is.
Let’s look into some of the reasons why your green beans may be turning brown and see if they are safe to eat.
Brown Spots on Green Beans: Why?
Looking at some of the major reasons why green beans turn brown, may be because the beans are not in their best state any longer.
When you begin to notice some brown spots on green beans, it usually means they are already getting old and stale. These green beans usually become mushy and they do not snap easily when broken into half. Therefore, this type of bean won’t be so fresh when you consume them.
However, this doesn’t mean they aren’t safe to eat. You can still eat them but you just won’t get that fresh taste. You can simply compare them to products or foods that are not spoiled but are simply past their peak of freshness.
If by any chance you come across this type of brown beans, you can simply make use of them in dishes that have bold flavors.
Note that both cooked green beans and raw green beans have the same shelf life and they can last up to a week in the fridge.

It may not necessarily mean they are spoiled, but you just won’t enjoy that fresh taste of green beans.

If the spots are few and far between, then it’s safe to say you can eat them without any problems. The only issue may be it may not taste as good! However, if the discoloration is significant and there are many spots, then it’s probably best to discard it to avoid any potential problems.
What Do Rotten Green Beans Look Like?
The easiest way to tell if green beans are rotten is by their appearance. Brown spots and discoloration is the easiest sign to see that your green beans are going, or have already gone rotten. Other signs may include limpness, sliminess, and misshapen.
When you’re looking at fresh green beans that have yet to be washed, they should look vibrant and bright. As well as this, they should be able to snap with ease. Instead, they may feel rubbery in texture, or even slimy.
If you’ve boiled your green beans and then place them back in the fridge, they’re likely to last longer, at around 5-7 days. However, if they start exhibiting any of the signs above before then, it may be best to discard them.
The same goes for frozen green beans. While freezing does massively increase the shelf life to around 6-8 months; they can still go bad. It may be easier to tell once they are defrosted. Keeping your green beans frozen is a great way to ensure they keep their snap.
As for canned green beans, they can last anywhere from an amazing three to five years. No matter what the best-by date is on the packaging, it’ll safely last well beyond that date. The only deterioration that may happen is mold, and an odor may eventually appear. If either of these things happens, it’s best to throw the can of green beans away.

If your green beans are slimy, likely, they are already past the point of no return. You want your green beans to be crisp and snap easily; not limp and slimy. If you notice that only the ends are like this, simply slice them off and wash them under water. When cooking them, you should allow an extra 5-10 minutes to ensure the delicious texture you’re looking for.
